266 REVISION OF ATTS'll;AI,IAX LEPIDOPTERA, VI., 



Gen. 4 6. Casbia. 



Casbia, Wlk., Cat. Brit. Mus., xxxv., p. 1667 (1866); Deilinia, 

 Meyr., Proc. Linn. Soc. N. S. Wales, 1891, p.634, nee Hb.; Tro- 

 chistis, Meyr., Tr. E.S., 1892, p. 110. 



Face smooth, or with short, rough scales, or with a small pro- 

 jecting tuft of hairs. Tongue well-developed. Palpi moderate, 

 porrect or ascending, rough-scaled; terminal joint very short. 

 Antennae in £ bipectinate, towards apex simple. Thorax not 

 crested, beneath somewhat hairy. Femora smooth, not hairy; 

 posterior tibiae in £ not dilated. Forewings in g without fovea 

 (except in rectaria, in which a moderate fovea with small central 

 gland is present); 10 out of 9, 11 from cell or out of 9, usually 

 anastomosing with 12 but sometimes free; or rarely, 11 appa- 

 rently out of 12. Hindwings normal; 8 approximated to cell 

 to about middle. 



Type, C. rectaria Wlk. I agree with Mr. Meyrick in restrict- 

 ing the genus Deilinia Hb. (for which, however, I think Cabera 

 Treit., may have to be substituted). The type of these genera 

 is pusaria Lin., in which there is a fovea at base of hindwing on 

 underside, and vein 8 diverges from cell at about L But I must 

 differ from him in not referring rectaria to that genus, for this 

 has a fovea in the forewing, not in the hindwing. On the other 

 hand, impressaria has the base of the hindwing in £ roughly 

 hairy beneath, but with no fovea. Vein 11 usually anastomoses 

 with 12, but appears to be always free in rectaria and albinotata, 

 and occasionally so in some other species. Rectaria and im- 

 pressaria are so closely allied to each other, and to other species 

 of the genus, that they should not be generically separated. 



Id'ea farinalis Rosen., Ann. Mag. Nat. Hist , 1885, p. 402, 

 probably belongs to this genus: the type is a wasted Q, which I 

 was unable to identify.
