A REVISION af tllc NEARGTIC' CIIRYNOI'IDIE.

Xvery enton~ologist knows Chrysopcc; for there are few regions in the world whcre insects abound unrepresented by Chrysopa, or sorrle allied genus. Throughout our courl try Chr?jsopa is represented in evcry 1oc:llity by several species; and everywl~cre there is a t least one species which may he reckoned among tlle " common insects." The delicate green color, the bc:tatiful golden eyes, anti, above all, the peculiar odor of certain species have made Chrysopa familiar to every collector of insects.

The Family Chrysopid~ is distinguishable from the other Salnilich of Ncaroptcra by the following characters :

Mouth riot rostrated, no anal space to the hind wings; anterior legs sinrplc (not raptatorial) ; wings bare (not powderetl) ; antetlnz sctiform ; costal space of anterior wing is narrow a t basr, no recur- renl vein, transvc~rse veinlets in gradate series. The filnlily is closely relatctl both in structure ant1 in larval habits with the Hem- erohiid:e, but a coloratiorlal character will idways separate thcm ; the Cl~rysopiclz are usually ~rlostly green, while the 1ienlrrol)iide are never grclen, hut rliore or less brown. Therr are various structural chitracters which separate tkic, two families. The pronoturn in Chrys- opidz is usually as long or longer than broad, in the Henlrrobiidze it is plziiirly broader than long. The wings of the C11sysopiclze have rrlally Inore cross-veir~s than in the Hcrnerobiidx:; tllc result is that most of the cells i n a Clirysopid wing are rarely rnore tllarl twice as long as broad, while in the Henlerohiid wirrg tllc cells are three times s r ~ d usually four to six times as long as broad. In tht, Cbrysopitlre thew is but one mdi:tl sector which is connected hack to ratliur I)y a t least six cross-veins. In the I-Iemerobiid~c there arc. usnally sevcral radial sectors, and thc last is conr~ccted back to the radius by only one to three cross-veins. 111 the Cllrysopidre the radial sector of the hind wing is united for sorne distance to the median vein ; this does not obtain ill the Hemerohiidz.

The Chrysopid~ are illsects of rathcr small size with con~para t ive l~ large wings. A t rert, the wings tire held roof like over the body, and. the antennz arc extended outward and forward. Their flight

is rrever rapid, and usually slow and soinewliat irregular. They fly little cluring day tirnc, and not Far even when disturbed. i l t twilight and in the early clvening their flight is more extendect, and they are then a t their best. Several species are attractecl to lights. Tllc fe'elnales appear to generally tleposit tlieir eggs in the arternoon or evening. P:tiring, as far as I have ol)servt.d, takes place in the day- tirr~e ; the sexes arc attached end to enti. T11erc arc no secontl:i~y iexnal charat.ters, savc in the genus Meleoncci, whr~re the male has a pr.otuk)erance hctwern the hases of the ariteiinz~.

The odor, so characteristic of sonre of the cornnlorier species of Chi-ynoprc, is riot (as has I~cerr noticed by sevt~r:~l writers) found in a11 of Lhe sprcies. (I. 4-ptirtctata is the most colnnlon of the inotlororis species, C! oc~cluta tlrc most coninlor) of the odorous ones. The cib ariarr structurrs are quite well ikvelopecl ; the ~narrdibles are short :t~itl stout; the rrlaxillx large, :~ilrl wit11 five jointed palpi ; tlrc 1:~bial palpi threc joiritetl. Vet, so far 21s I am aware, the adnlt insect takes no ~~ourishment. IIowever, they probably live for a week or rlrore. \Vlren they die, tlieir frail I~otlies rliust sooii dibappear, a8 T have never found a cle:~d specirr~en.

The genital orgxlis in nearly all of our species are withdrawn in the last segnients of the abdorrren ; they are rather soft and probably sllririk ill drying. They have beerr used in the separation of sonle European forms, but in the few closely alliect forms that I have cx- arr~illed, thcy are not useful. The tarsi tern~inate in two claws, sirn- ilar in character in all of our species.

Cll~ysopa has long been familiar to entomologists on account of its rcnlarkable larval habits. They p:rss the wintrr usually as pupx, but a t least one species, Gl~rysopu plorahtcrzdu, hiberilxtcs in the :tdtllt state. F1ic.s of this species l~nvc beon found in hedges and heaps of dry leaves d~rririg January, February ant1 March. The hibernating pup% hatch, according to the species, from March to June. The flies rnate as soon as possible, arid tlier~ the fcmalcs pro- ceed to attach tlieir curious eggs in fhvorable situations. Thr egg is elliptical in sliapcl and attached a t one end to a long slender petlicel, whose base is expanded and attachctl to the leaf or twig. IJsaally there is hut one egg to each stalk ; b r ~ t I have found in July a single stalk on the hark of oak trers, which bore a t its surl~rr~it a cluster of ten or fifteen eggs. I did not succeed in rearing the 1arv:e. A t least one European species has a similar habit. In some species the

AMERICAN NEUIZO~TERA. 139

eggs are laid in groups of frorn eight to thirty (C. ooculata), in others the eggs occur singly (C. ~ u j i l a b r i s ) . I n the latter class the pedicel is often shorter than in the former group. I n many cases the eggs are laid in proximity to colonies of plant-lice, upon wllicll the larvz are dcstiried to feetl. Sometimes, Ilowever, the larva are obliged to search for food.

A t the top of each egg is a rnicropyle-a cup shaped piece pro jecting abovc the snrface, with a nlinutc central pore. Tlle top of the egg is irregularly reticulate ; the base is rrrore pointed than the top. Thc egg in a clay or so heconles darker, and cracks arross the top arltl partly clowri one side. Through this slit tho larva crawls out. t is very bristly, has a big heid, aucl a tapering body. Tlir jaws are very large, the antennz long and cnrvecl, and the pal1)i hroad and pro,ject out in front. Tlie legs are slender, and each tippcd nith two claws and a longer rncdiar~ sucker. The larva of each spccies is char:~cteristic, tliough l a rvs of closely allicd forms differ but littlc.

The larva crawls down thc pedicel to the leaf, and soon rnonlls. Fitch has recorded that in son~e species tkle first food of the I:~rva was eggs of other insects, aftcr which the larva aitackctl plant lice. In other species, however, the l a r v ~ do attack plant-lice ihr their first mcal, ant1 are not as tinlid as Dr. Fitch rccortls of' the larva he observed. As thc larva grows in size it becomes more fusifhrn~ in shape, arid in many species each segrncnt develops a lateral prolnbcr- ance hrarirrg a bunch of bristles. Tlie color becon~es d:trker alrtl often spottecl ; the larva of the few speoies known to rile being marked in a iiiffercnt manner. Tlre questiorl of the larval rr~oults is one of peculiar interest. The new horn larva soon moults as is r~atlily 01)- servable ; but f ion~ this time till it lno~rlts within the cocoon rllost i~uthors have ok)served no nloulting. Fitch and Schrleitler record that they have not seen a moult, aud I have watched in vain. Vinc tiescribes one rnoult about rnidway in larval life.

The larvw of sorrle species covcr tllcrnselves with a pile of debris, made up of the slii~ls of their victims. This scalp-carrying habit is also fourltl in thc larvze of sornc Henierobiids. I t is a protection ; but sorue specics that tlo not have i t are extremely numerous ant1 appear rnotlerately free from pa~xsites. I n travelling ahoat on the leaf or hark the larva ~valks in a restless, ir~tcrrupted may, turning

tlie lieatl from side to side, and keeping the palpi in rnotion. Tlie tail is often useti to liold or1 to sonie spot, but wlier~ not in use is oftell mrried turned to one side.

These voracious littlc l a r r : ~ are kliow11 as " aphis-lions ; " t h ~ i r principal food being aphids. However, they will feed or1 allllost any soft insect, and even upon each otlier. I t scizcs the apliitl with a qi~icli rrloverner~t of the .jaws and rapidly sucks thc unrortunate vie tirri dry, often turning it arountl in order to extract all tlic juices. I n this rnauner they tlestroy a great numbcr of plant-lice in a (lay. The irillurrlerahle hosts of aphids wit11 their remarkable fccantlitj are no ma~ch fhr the ravenous appetite of these C1~1.ysopa larvze, aiid i11 a fcw (lays plants badly i~~festccl witli "green fly " are (aletin again. Their useful Ilabits have been comrrieritetl upon by alrnost every eeorio~nic entolnologist ; not only in the destruction of plalit lice, but as attttclring the pear-tree l'sylla, scale insccts, the clliiicll- bug, elm-leaf hcetle arid other pests

The length of the larval life is from one to three weeks. \Vl~rn a proper size is reached the larva rests for a tirl~e and tller~ proceeds to spin thc cocoon. This niay he placetl almost anywhere, so~nctirnes in a crevice of the bark or a fold in the leaf, but quite as often tlrcy are fully cxposccl to view. The larva, wl~icli is now firsifor111 in shape, spins around itself threarls \vhich are tlrawrl tighter and tighter till the larva is curled upon itself as closely as is possilr)le. The spinning continues ailti results in a practically spheric:~l cocoorl, wllite or yellow i r ~ color. Sorne cocoons are more elliptical tllar~ others.

The silk glands open near the end of the abdomen, anti they errlit :L single srnootli thread.

After a pcriotl of about ten clays thc pupa cuts off a circular lid from thc csocoon arid crawls almost or completely out. The niar~dihl~s of tlie p u p arc short, stoat anti sharp-pointed, enabling tlie creature to cut through its tough cocoon. I n a few riiinutes its back bursts alor~g the rncdian line airti ikon1 it gradually issues the adult f l ~ ; at tirst pale and weak, but ill thc course of an hour or so tlssunies its full coloration and development.

Shilrler lias noted that in a larva that liad but four legs, tlie adult fly frorn it had all six legs fully developed. Since the (:hrysopid larva lives exposed it is not strange that they are attacketi by vari- ous parasites. The Chalciditls, f'erila~r~pus hynlirrtcs, Clirysopgha-

Sirriilar to Chrysopa, but tlie third cubital cell is nearly equally divitlctl, the tlivisory veinlet running into the entl-veinlet of thc cell instead of into the upper margin. The anterlrrz are quite long, their bases close togetlrer. There are two full series of graclate veinlets in eacli wing. Type A. uirginica.

Chrysapa cs l i for~~ica Coquillett.-Pale green or yellowish, with a pale niedian dorsal stripe in life. Clleeks suffused with red, anrl often a red dot above on vertex near each eye. Venation pale green or yellowisl~, pterostigma niodcr- ately distinot. Pronotnm about as broad as long, sides parallel, riot narrowed in frout.

Also fi'otlt IIootl River, Oregoti, Scptenlher; I'ullrnan, lv:tsh., July anti ~ l r i g r ~ ~ t ; and King's Canort, Ormshy Co., Nevada, July. It is harely more than a variety of Ch. han*n*isi, but I rlnderstalid that Hagen considered it a distinct species. I t is the moqt abundant species on the Pacific Coast.

Clrrysopa extcrna Hagen.-Pale green or yellowish, not showing a dis- tirict pale median stripe; cheeks roddish. Venation green, pterostignla not clis- tinct. The pronoturn is about as broad as long, but t h e sides converge a little forward. T h e wings arc slender and arnte a t t ips; tlie divisory veinlet ends bc- fore the middle of the nell and before the cross-vcii~let. Tlie venation is rrot as dense as in the allied spec,ies. Length 11-14 ninl.

Gpecirnens have heen seen from 1,:~s Cruccs, June, Sa l~ ta Fe, Aug., autl Mcsilla, New Mexico and also frorri Yurna, Arizona, and Palrn Springs, Cala. (Feb. 14th). The variation upon which the specific name is h s e d occurs also a t titrles i r ~ the allies species, and one of Hapen's specirne~~s, that fronr D. C., 111ast have bee11 a Ch. harrisii. Nevertheless I have retained tlte rrsrrle for those specilnel~s ~ l ~ i c h show the variatiori irl all extrernc degree.

M E L E O M A Fitcli.

The genus has the venation about as in Chrysopa. Tlie anterlnz :Ire Inore widely separate a t base than in any of orrr other forms, alld in the rvlale there is an inter-ar~teur~al protuberance or 11orr1. The basal joint of the antenna is more slender tlla~r irr Chrysopa. The species appear to inhabit mountains. Type is 31. signorefti.

Our three species are separated by the following table :

1. 1Iot.n of male as l o ~ i g aa., widtli of vertex; second and third ,joiois of male a n t e r ~ u a simple; no line on olieek in either s e x ; pradate veinlrts blaclrish ........................................... signoretti.

jeotir~g in front in two recldisl~ snb~l~ecliau tuhrrcles; I~etween an te lnm arises a prominent hol.n which is :LS Ioug as width of vertex. and projects out Iiorizon- tally, its end bent vertioally downwartl and provided with a stiE hiGd brush of pale rt?ddisli ha i r ; in tlie fernale this and the tubercle are lackirig ; vertex elevated tra,nsversc.ly hetween the ryes. T h e a n t e n n a are darlreued beyond the base, but not black, it1 lengtli scarcely reaching to middle of wing. Prothorax a little longer than broad, plainly narrowed in frout, and with a transverse ridge I>eyoud the rr~id~lle . Venation ol' wing green, witli tlie gradate veins blackisl~, as also the bases of tlie cross-veins fro111 the radius, and one or two cross-vei~~s in the anal region, lower half of b:~se of third cuhital cell and connecting veinlet to the radial sedor aud end of the divisory veinlet of third cobital cell black. Lcngth 14-16 nlrll.

Specirnel~s conle frorn Mt. TVasI~ington and Frallconia, New IJarnpshire, and frorn Sea Cliff; N. Y., J u l y ; Fitch's specirnen was frorn the Green ;\Its. of Vermont. Thc type was, according to Hagen, purchasctl for the M~sseurr~ of Cornpartitive Zoology, but there is a speciinrn in thc National Museuni from the old Fitcll collectioa.

Meleoina slosso~ra Banks.-Pale green or yellowish when dry, a red- brown stripe from eye to mouth ; palpi marked with rcddish, a da rk spot on each :tnteriol. side margin of pronoturu. Veriation green. many of the cross-veinlets ill p:rrt blac:lr ; pterostigrna long and distinct. I n the nmle tlrore is a cavity in riiiddle of face below an tenna , between bases of m ~ t c n n e is a short, broacl tuber- clc, trifid a t tip ; tlie vertex is transversely elevated fro111 eye to eye. Antenna with basal joints slander and ciivergent, curved, concave within, second and third .joiuLs short, fourth longer and swollen a t base on inuer side. I11 9 there is no tubercle, hut a sliglit conical elevation ; the basal joints of a r ~ t e n n a are simple, as also the foclrtli. I'rouotuni broader t l r t ~ ~ ~ long, sides nearly parallel, a little nar- rowed a t extreme front. Wings moderately long, anterior p a ~ r roundcd a t apex, hind yalr acute a t tip. Length 18-19 ulrri.

Specimens have beerr taker1 by Mrs. A. T. Sloseon frori~ Rlt. \FTashington, Crawford Notch and Franconin, New Halups11il.e; also seen frolr~ Iirookline, Mai i~e; and Quebec and Shcrbrooke, Car~:itla. This species differs much froin Jf. signoretti, in structure of antenna and the tubercle. Mr. McLaclilan i r ~ a uote i r ~ Ent. News, 1894, tlliriks t h t it is a sex of M. s igr~oret t i ; howcver, there is not the slightest doubt of their distinctness, and that the female Meleo~na is without a horn.

Meleorna illnovat& Hagen.-Pale green ; a pale yellowish dorsal, rnedian stripe ; a red-brown stripe from each eye to mouth ; palpi marked with reddish. I n male the lower part of face is git)l)ous, a cavit,y above i t marked with pink ; between bases of antcnna: a small tohercle, hifid a t tip end curved downward. Basal joints of antenurn divergent, and swollen near tip, especially below, beyond sirnple. Fenrale without these structural ruodificxtior~s, but tho basal joiuts a re widely separate a t base, and much ~ ~ ~ o r c slender than in a n y C'hvysopa. Wings rather long and slender, anterior pair rounrlcd a t tip, hind [,air acute a t tip. Venation green, some cross-vcinlets marked in part with black ; pterostignia quite distinct. pro not an^ broader than long, not narrowed in front. 1 ~ ~ 1 g t h 18-20 rum.

I have a pair; male from Amecarneca, Mexico, the female frorn Santa Fh, New Mexico, July. A t the tinie of my description of M. rnexicanm, which was based or1 the former specinleli, I had riot exeminctl Hagen's description of Ch. in?~ovnta carefully. I t is strange that FIagen did not place this species in Meleomu, since he states that it possesses the very character upon which this genus was based.

EREMOCHRYSA now gen.

Cliaracters in general those of Cl&r?ysopa, but there is hut one (the outer) series of gradate veinlcts in hilid wing" the branches frorn the radial sector being cnrved and hinuate. Tn the forewings the inner row of gratlate veinlets are only tllrcr or four in riurnber. - The wings are narrower than in lllost spccics of Chrysopa; the longi- tudinal veins are usually marked with brown, and there is usually a brown dot under the tip of each femur. Type Ch. p~~tzetinwuis JvlcLach.

Three species car1 be referred to this genus, arid they may be re- cogriizetl fi-oln the following table :

San Antonio, Texas, and Austin, Texas, May 20th ; the latter from Mr. McClendon. A very hantlsorne and distillet species, not very closely related to any other ill our fauna.

Erelnochrysa pur~etinervis McLach.-Head yellowish ; a blackish uiark under each eye reaching toward mouth, a spot betwcei~ base of anteiiua:; palpi barldcd with red-browr~ ; basal joint of ailtennw often with ;L red-brown spot on inner upper side, a narrow line oil outer s ide; sccond joint often with a dark spot above, but not wholly black. Pronoturn rrsal.ked each sidc with red- brown, as likewise meso- and nletathorax ; abdomen soruewhat marked with brown ; legs pale, a brown dot lindcr tip of each femur. Wings grayish Iiyaline, veins and veinlots interroptediy pale and rccl-brown, sonietinies sonre of the cross-veinlets are wliolly dark, gradate veiulets brown; hii~rl wings sinlilttrly marked. Wings narrow, rour~decl a t tip, hu t three or four gradate veiulets in each serics, iii hind wings but one (the outer) series of gradate veinlets, third cubital cell dlolit twice as long as broad.
