Diagnostic Notes
Adult

Medium-sized to very large with broad forewings, often with a darker subtriangular pretornal patch and usually with a small accessory cell with chorda from between R2 and R3 to between R4 and R5. Hindwing with short cell, especially in male, and thorax with an often conspicuous crest. Male: Often have secondary sexual structures such as a modified hindtibia with tufts of hair-like scales, a modified hindwing with sometimes an elongate, heavily sclerotised pocket filled with fine hair-scales beneath in distal half of CuA2, long and mane-like scales dorsally on the abdomen. All species have T8 with a medial subtriangular or Y-shaped plate and with paired tufts of long filiform scales arising from shallow membranous pockets on each side, and nearly always coremata with tufts of modified, short, swollen scales. Genitalia: a strongly swollen, clavate valva with few sparse, very large spines on the inner surface of the cucullus, and with dense, very long, curled scales on the outer surface. Female: Genitalia: sterigma is very variable but fused with the deeply excavated hindmargin of S7, the corpus bursae is usually spinulose in anterior 1/2-4/5 and sometimes has a diverticulum, and the signa are two curved horns.

Larva

Body length of mature larva 13-20 mm. Body usually fat, yellowish white (body colour at maturity turning red dorsally). Pinacula large, darker than body colour. Spiracle on A8 near the posterior margin. Prolegs with biordinal crochets. Anal fork usually absent. Chaetotaxy: SD1 and SD2 on separate pinaculum on A1-A7; D1 and SD1 on same pinaculum on A9; SV group on A1-A7 trisetose, on A8 and A9 bisetose, or A9 unisetose; L group trisetose on A9.

Pupa

Body length 9-15 mm. Pupa stout, with dorsal spines rather strong (especially on A8-A10). Body colour unifoimly pale yellowish brown. Spiracles large, transversely ovate. A2-A7 with 2 rows of dorsal spines, A8 with one row of dorsal spines. A10 with 1-5 spines caudally and a pair of spines along anal rise, usually without hooked setae except 2 pairs along anal rise.
