Port Natal (Plant, Gueinzius) ; Sierra Leone (Morgan). B.M. 
Wallengren (Ofv. Vet. Akad. 1871, p. 913), publishes his opinion that his C. trans- 
Jigurata is =B. idricus. 
Genus 10. Gnatuostypsis, Wallengren. 
Gnathostypsis, Wallengren, Ofvers. Kongl. Vetensk-akad. Férhandl. 1858, p. 137. 
Allied to Cherocampa. Antenne with recurved apex, furnished with a fasciculus of 
rigid hairs. Palpi ascending, forming a projection in front of the head as in Cherocampa, 
hairy; last joint large, acicular, pilose, robust ; intermediate joint laterally compressed, 
with a slender fringe of hairs separated from the last joint by an interval destitute of 
hairs on its outer edge. Proboscis long, not concealed. Head porrect; vertex convex, 
crested. ‘Thorax sloping from the vertex, very convex on the dorsum, smooth, with the 
pterygodes appressed. Abdomen thick. Form of the wings almost as in Chwrocampa, 
but broader; primaries with the apex not falcate, external angle more rounded; second- 
aries with outer margin not excised. 
GNATHOSTYPSIS OSTRACINA. 
Gnathostypsis ostracina, Wallengren, Wien. ent. Mon. iv. p. 42. no. 43 (1860) ; Kongl. Svensk.

Caffraria. 
Genus 11. Dioposrpa, Walker. 
Diodosida, Walker, Lep. Het. viii. p. 163. gen. 19 (1856). 
1. DroposipA MURINA. 
Diodosida murina, Walker, Tep. Het. viii. p. 163. no. 1 (1856). 
Darapsa marginata, var. 8, Walker, 1. c. p. 185. no. 5 (1856). 
2, Port Natal (Stevens, Gueinzius). Type, B.M. 
2. DI0DOSIDA MARGINATA. 
Darapsa marginata, Walker, Lep. Het. viii. p. 185. no. 5 (1856).

Very distinct from the preceding, but unquestionably belonging to the same genus. 
3. DroDosiDA FUMOSA. 
Zonilia fumosa, Walker, Lep. Het. viii. p. 193. no. 3 (1856). 
Congo (Richardson). - Type, BM. 
The palpi in this species are rather long for the genus, and the prothorax is rather 
prominent; but the distinctions are scarcely sufficiently well marked to warrant its 
generic separation.
