XIV- Additions to the Cicindelid^ fauna of Mexico, ivith

remarks on some of the ^previously -recorded species.By Henry Walter Bates, F.R.S,, F.L.S.,

I Read May 7th, 1890.]Plate XVI.

The object of the present paper is to make known theadditions to the coleopterous fauna of Mexico, as far asregards the family Cicindelida, which have been receivedby Messrs. Godman and Salvin since the completion ofColeoptera, vol. i., part 1, of the 'Biologia Centrali-

Americana,' and to describe such sj^ecies and wellmarked varieties as appear to be new to Science, cor-

recting at the same time the descriptions and identifi-cations of known species by the light of the more

mater

In the * Biologia' thetotal number of Cicindelidce recorded was 61 belongingto 5 genera. In the present paper the total is increasedto 78, the additions, 17 species, belonging all to therestricted genus Cicindela.

Excepting the conspicuous and separated maculationof the elytra this form shows no difference from the type-form, and from numerous varieties of C. ohsoleta found inColorado, New Mexico, and Texas, none of which exhibita similar number and form of spots. The second andthird spots are always distant from the margin, and the

tinguishes them. The species, in fact, isintermediate between C. ohsoleta and C. pulchra. In allthe examples the under surface is destitute of hairs ;none at all are visible on the sides.

strongly j)i'ominent, and the sides of the vertex aresharply striated, the central part, as well as the occiputand neck, being nearly smooth or very finely alutaceons,like the convex disk of the thorax on each side. The elytraare rather strongly punctulated throughout, towards thebase granulate-punctate, and the large bluish roundedshallow umbilicated foveoles are scattered from the basenearly to the ai3ex; the apices are separately rounded,the edges not serrulated, the sutural apex spinose.

s sj^ecies comes nearer King's description of hisC. semicircitlaris than any other Mexican form that Iave seen. It agrees in form, which Klug says is that

of C Jiexuosay but it differs in the colour of the head,

in the labrum being distinctly unidentate in the ? , inthe impunctate thorax, and in the absence of a secondsubmarginal spot on the elytra ; and it may therefore bea nearly allied and distinct species. At any rate, thespecies referred to O. semicircular is in the * BiulogiaC.-A.,' on the authority of French collections, cannot be

armed and the thorax as finely punctured, the wrongly-

named insect having the labrum greatly produced, almostnarrowly sublobate in the middle in both sexes andstrongly tridentate, aiid the thorax rather coarsely anddensely sculptured. It will require, therefore, a new

name :

This cmious little species is evidently closely allied toC. lyrcEciiii^ though having much in common with (7.Hoegi (Bates). The head and thorax are of nearly thesame form, at least in the ? , the ^ differing strangelyin the head being narrower and less convex ' behind theeyes, and the thorax less rectilinear on the sides. Thebasal part of the elytra appears flattened, owing to the

epiplem'ae being vertical in conjunction with the mirror-

like marginal stripe, and forming a rectangular edgewith the disk, which edge is curiously sinuated at thepoint, where a brilliantly polished narrow subflexuousoblique vitta is emitted to the disk. The eyes are moreprominent than in C. j)rcecisa, and the concave vertexmore completely covered with sharp partly concentricstrino. The thorax is finely striated in different direc-

, and the sulci are still more faintly impressed than

in C. lyrcEcisa. The elytra are finely alutaceous, besetwith bluish green punctures, the interstices of which are

minutely marbled with cupreous ; the apical margin isnot serrulated, and is oblique and straight for a shortdistance near the sutural angle, which latter iS' spinose.Beneath blackish blue, glabrous on the sides ; femoraaurescent. The labrum is broadly produced, subtrun-cate, unispinose in the middle, as in C. prcecisa^ but thecentre is strongly longitudinall}^ convex, and the sub-

marginal setiferous punctures are less numerous and

spicuous.

species has, since the above-cited description was

published, been received in numbers from various locali-ties, particularly in the Province Guerrero. The firstexamples received were all of a coj^pery aeneous hue ; mostof those lately arrived are greenish brassy brown, opaque,with rather brighter aeneous or coppery head, thorax,and elytral suture, the green umbilicated foveoles of thelatter conspicuous against the dark colour. The whitemarkings also are more developed than is described inthe type-form, in which they consist of a short obliquestreak on the disk, with a small posterior discoidal spot ;

many examples having an apical lunule and margposterior spot. The following variety has the aspect ofa distinct species :

Hah. Cuernavaca in Morelos {Hoge) ; Chilpancingoin Guerrero {H. H. Smithy Hoge).

The white markings in their full development muchresemble those of the var. Taretana of C. hydrophoha(Chevr.) In some examples the humernl lunule is widelyinterrupted in the middle, and the apical lunule discon-nected from the postero-discal spot, or the latter dis-appears altogether. The abdomen and four posterior


trochanters are. red in all the varieties, and the speciesclearly belongs to the rufiventris group, from all theothers of Avhicli it is distinguished, besides its small size,by the vaulted subsemicircularly produced labrum, un-armed in the c? , and sharply unidentate in the 2 .

The white markings differ from both speciesespecially in the median fascia being uninterrupted and

less oblique, by which its dilated apex lies very littlebehind the middle of the elytra and nearer the suture ; asubmarginal line extends from the humeral lunule tobeyond the middle, but it is narrower and lies nearer themargin than in C. dyscnterica. The head is sharply and

strongly striated, the striae covering the w^hole crown,and the forehead has two purple vittae. The thorax isstrongly sculptured. The elytra are nearly conjointlyrounded at the apex, the apical margin not serrulated,and the suture not spined. The hind trochanters aredark metallic, the abdomen red, with base more or lessdusky.

Cicindela rufiventris^ Dej.

Among the great number of examples of the differentvarieties from very numerous localities referred in the

* Biologia ' to this species on the authority of Chaudoir,I have failed to find a single specimen agreeing withDejean's description in the essential peculiarity of theelytral markings, viz.^ a crescent-shaped apical lunuleand three detached spots in triangle on the disk. Thedetached spots of course represent the marginal and dis-coidal ends of the median fascia and the posterior mar-ginal spot, but in Mexican examples it invariably occursthat when the median fascia is dissolved into spots theapical lunule is also disintegrated* The apical lunuleremains entire \yhen the median markings degenerateonly in closely-allied N. American species, e. g., C. cuvia-tills. Dejean's example was from Palisot de Beauvois's

collection, and labelled ** St. Domingo"; whether this iscorrect, or the specimen came from the south-easternStates, is doubtful, and the Mexican forms perhaps donot belong to the same species.

This Texan species occurs in the States of Tamauh[)asand Coahuila, under the same form as in Texas ; but atYilla Lcrdo in Durango, where it has been collected inlarge numbers by Mr.Hoge, it presents itself as a tolerablywell-marked variety, being generally smaller, the elytra

relatively a little shorter, and the white spots larger, thetwo median spots being sometimes more approximatedthan usual with traces of a fine line connecting themtogether.

The southern form of this common Cicindela is on theaverage smaller, and lias a decidedly narrower thorax ;the hind trochanters also are always red like the abdo-men, the latter having little or no trace of fuscous at thebase. It is a more important variety than any of theothers described under this species, and I propose to callit after the name of the State which appears to form itshead-quarters.

Thespecies forms a transition between the sijerata-marginatigrouj) and the trisigiiata and hirticollis group ; the whitepubescence of the sides of the body beneath, thoughrather dense, is less adpressed and felted than inC. marginata and allies* The labrum is short and broadrectangular, with the median part very slightly i)roducedeven in the 5 The thorax is narrow^ nearly cylindrical,

and minutely, irregularly sculptured. The elytra are

proportionally rather long, broader behind, with con-

jointly rounded and sharply serrulated apical margin ;the surface is very regularly, equally, and finely granu-late-punctate, with very dense and j5ne punctuation onthe interstices. The under side and legs are bluish

green, the four posterior trochanters iiurple-metallic.

There is a large series of this elegant species fromof the two localities named above- Those fromAcapiilco show nearly all a larger extension of whitecolour on the elytra than those from Manzanillo.
