Face smooth. Tongue well developed. Palpi moderate, 

 obliquel}' ascending; basal joint with long spreading hairs; second 

 joint rough-haired above and beneath; terminal joint moderate. 

 Antennae in ^ pectinated, apices simple. Thorax and abdomen 

 not crested; thorax densely hairy beneath. Posterior legs of ^ 

 [unknown]. Hindwings without costal expansion at base; frenu- 

 lum and retinaculum in ^ well developed. Forewings with 3 

 and 4 separate, 6 separate, 10 arising separately from cell, 11 

 anastomosing with 12. Hindwings with 3 and 4 separate, 6 and 

 7 separate, 8 closely approximated to cell to well beyond middle; 

 discocellulars incurved, not oblique. 



Type, Psendoterpna castanea Low. I regard this as the most 

 primitive genus so far known, and as almost in the direct line of 

 ancestry of Ter'pna.
