Black with the somewhat densely pubescent abdomen entirely con- 

 colorous, the seventh segment excised and terebra almost shorter than the 

 postpetiole ; all the femora and tibiae red, coxae and trochanters black ; 

 recurrent nervure emitted from near centre of the areolet ; stigma pale 

 and fenestra large. Length, 6-7 mm. 



Differs from all our other species with large fenestrae and margined 

 mandibles in its black abdomen and anterior trochanters. 



Not very common, though widely distributed, in northern and central 

 Europe. It has been bred by Brischke from a Noctuid pupa, by Mocsary 

 from Orgyia cricae, by Bridg. -Fitch (Entom. 1885, p. 19) from O. fascclina 

 by Harwood, who writes to me " I once found this moth in some numbers 

 at Colchester and bred a good many specimens of C t'(^t7n«//j' from them," 

 and Bignell {lib.cit. 1883, p. 66) raised it from the same host. But there 

 are no other records of capture and it is certainly uncommon with us. 

 Bradley has found it about Birmingham ; Capron took half-a-dozen, in- 

 cluding both sexes, in Surrey ; Miss Chawner has given me a New Forest 

 male; and Garde captured it at Chatham in May, 1892. Keys bred a 

 female from its irregularly black-bicingulated dull white cocoon, the outer 

 covering of which is formed by the indurated skin of the defunct host- 

 larva whose pale head is always attached to exactly one extremity; this 

 was found on Rhamnus Frangida on the banks of the Dart, near Ash- 

 burton, on 8th July, 1903 ; Gaulle gives Pieris and Gonepteryx as generic 

 hosts, so the above may have emerged from G. rhamni. \\\ the British 

 Museum is a female of this parasite together with the indurated larval 

 skin of Cluysophantis dispar, from which Stephens had bred it in the 

 Cambridgeshire Fens many years ago. 



5. carbonaria, Ratz. 



Canipoplcx carhonarius, Ratz. Ichn. d. Forst. i. 93, s ? ; ii. 82; iii. 83; Brisch. 

 Schr. Nat. Ges. Danz. 1880, p. 144, ? . Anilasta carbonaria. Thorns. O.E. xi. 

 1170, ? . 



Black with the abdomen entirely concolorous, and the terebra hardly 

 extending beyond the anus ; all the femora and tibiae red, trochanters 

 except basal joint of the hind ones concolorous ; recurrent nervure 

 almost continuous with external nervure of areolet ; stigma pale and 

 fenestra large. Length, 6 mm. 



The distinction from the last species is not very pronounced and the 

 records seem much intermingled. The pale trochanters, shorter terebra 

 and, Schm. adds, position of recurrent nervure are distinct. 



Ratzeburg describes the larva and pupa of a female he bred in the 

 Hartz Mountains from Orgyia antiqua, adds tiuit Graff, Bouche and 

 Nordlinger raised it also from O, fascclina, the first from Tortrix pkcaiia 

 [xylos/cana), and that a probably synonymous male emerged from Lophyrus 

 pini\ later Brischke bred it from O. gonostigma in Prussia. F21sewhere it
