(Gorky Slate Lnilersily)

In the Soviet Far East the genus Onco;r.sis Buuneister, 183E is representedLry a great number of species nranl' of rvhich are apparently endemics. Be-cause of the extensiye individual varialion it is often difficult to identify someof the species on exlernal characters alone. The male genitalia, however,offer good specific characlers.

The following is a description of one new subgenus and seven new speciesof leafhoppers of the genus which have been found in the Soyiet I.ar East..{ key of all wellknou'n Palaearctic species is also given. All species live ontrees of the Betulaceae famill'.

The types of new species, rs well as the rest of the material here lreatedare in the author's collection aud in the collection of the Leningrad ZoologicalResearch lnstilute.

Subgenus Sispocrris nov.

Tvpe of subgenus BUthoscopus jugTlcns \Iatsumura, 1912 (F'igs. l-8).Differs principally from Oncopsis s. str. in the follorn'ing characters: py-

gofer with strong spine on dorsal side: aedeagus with unpared teeth on sidesnerr the top and with two pairs of teeth on ventral side; appendage of analttrbc rvith underdeveloped branches.

Subgenus Oncoptit t. str.

The species of the subgenus Oncopsis s. slr. are forming two groups. Therepresentatives of the first group have an aedeagus with a saddle-concaveddorsal margin. Three Palaearctic lO. llaoicollis (Linnaeus, 1758), O. sub-angulata (J. Sahlberg, 1E7l) and O. carpini (J. Sahlberg, lETl)l and allknortr'n Nearctic species [O. sobrias (Walker. 185f), O- minor (Filch, 1851),O. nigrinasi (Fitch, 1851), O. coloraclensis iBaker, 1898) and O. uariabilis(Fitch, 1851)l belong to this group. The representatives of the second groupEnto,nt. rs. .h.t. t6. 8. 3 _ t, 196;

have a penis with a conver dorsal margin. The majority of Palaearctic spe-cies including all new ones belong to this gmup.

Oncopsis (s. str. ) (drrstrr sp. n. {FiBs. 20-22)Crown is black. Face is yellow with black band between ocelli. This band

is connected with the black field on the crown by a middle black stripe.Pronotum is brownish-jet-black rvilh a more pale posterior margin. Sculellumis black. Palecoloured specimens have yellos-brorvn pronotum with blackspots on anterior margin. Forewings are black with transparent borderingof claval suture, wilh lransparent costal margin and with more or less visibletransparent band on subapical cells. Clavus black, apical cells dark, veinsare bordered with black.

The male genital segment is rer)- characteristic. -{edeagus as in O. (Ini(Shrank, 1801), i.e. with convex dorsal margin. Stilus gradually widening toapex. Appendage of anal segment with one strong unbranched process, Iurnedto ventral side. No one of known species has such r process.

Oncopsis (s. str.) ccliginos( sp. n. (Figs.23-25)General appearance:rnd colour is like previous species. It is distinguished

by larger size, pale basis of clavus, more rvide and pale costal margin andmore wide and pale bordering of claval suture.

It is rvell distinguished from previous and other well-known species bystructure of anal tube appendage. Penis as in O. (lni convex all the wa]'along dorsal margin. Stilus with approximately parallel sides. .{nal tubeappendage with two branches - ventral and dorsal. \'entral branch issemicircularly bent dorsad; it is broadened or sligthly bifurcated at the end.Dorsal branch of appendage is short, subparallel lo apical part of lhe ventralone. O. obstructo Dlabola, 1963. has someu'hat similar anal tube appendage,but it is of another general appearance and has a \yell-distinguishable stilusrvith dorsal part sharply broadened.
