A black species with Ihe abdomen apically c3'aneous, ils centre and 

 most of Ipgs red; terebra short. Head but slightly constricted pos- 

 teriorly; face with testaceous pubescence; palpi and part of mandibles 

 fulvous. Antennae somewhat stout and hardly longer than half body. 

 Thorax with the propleurae nitidulous and di.stinctly striate below; meso- 

 pleurae rugosely punctate; acetabulae centrally bilobed; metathorax with 

 the basal areae distinct and the central impression deep, broad and 

 coarsely rugose. Abdomen black with the third segment entirely, the 

 fourth partly, and the second apically al)ove, red; ventral plica infuscate; 

 anus black with distinct blue reflection ; petiole with lateral foveae and 

 the postpetiole narrow ; terebra short. Legs fulvidous with coxae and 

 trochanters black, and both extremities of hind tibiae piceous; hind 

 femora vary from entirely fulvous to entirely black. Wings with stigma 

 and part of tegulae fulvous; areolet subsessile, emitting recurrent nervure 

 beyond its centre ; radial cell broad with apical abscissa of radius straight 

 and hardly longer than the basal ; lower basal nervure a little postfurcal. 

 Length, 6-8 mm. 



Our only species with the anus at all blue, excepting C. sobolicida ; the 

 short radial cell is distinctive; but the colouration of the hind femora is 

 very variable. 



Not very common with us, though taken at Harting in Sussex bv Beau- 

 mont in the middle of August and both sexes have been bred by Bankes 

 on " ist-3rd June, iqoo, from larvae of Eiipi/hccia -rfiosci/a, Fb., collected 

 at Salisbury in 1899"; bv Clutten from Lepidoptera at Burnley in 1907. 

 I ha\e taken a cou{)U' I il fi-nialcs on oak in Sta\erton Thicks in Suflblk 

 on 24.tli June, 1903, and in llie W'iherley Inclosure in the New Forest 

 on ()tli |ul\', 1909.

A black species willi llic anus not at all cyaneous, the- abdomen 

 centrally with anterior femora and tibiae fulvous, hind tibiae black at both 

 extremities and the terebra shortly exserted. Length, <S nnn. 9 onlv. 



It is said by Thomson to be very similar to C. obnpUnis in its size, the 

 ca{)ital, antennal, thoracic and abdominal structure, but with the last 

 strongly compressed with its second segment more broadlv red, the 

 stigma somewhat narrow and emitting almost before its centre the radial 

 nervure, which is a little simialc towards its base. Tlu^ British records 

 are pnjbably founded on tlir pleural conformation; the [)roj)leurae are 

 shining and obviously slricjlate, transrugose below their centre ; the nu'so- 

 pleurae are somewhat coarsely pimctate; and, as in the last species, both 

 the mesosternal acetabulae are centrally bilobed, and the central meta- 

 thoracic impression is broad and deep with strong rugosities. 



Thought by Thomson to be nearly confined to ci-ntra! (iermany.
