Head with roughly appressed scales, in female forming a crest on 

 vertex. Ocellus posterior. Proboscis rather weak and short, es- 

 pecially in male. Palpus moderate, porrected, with rather closely 

 appressed scales, slightly rougher in female, median segment rather 

 curved in male, sinuate in female, roughish along upper edge towards 

 apex, terminal segment moderate. Antenna short-ciliate in male, 

 ciliations imder 1/2, pubescent in female. Thorax smooth. Posterior 

 tibia in male sometimes (type species) densely but smoothly scaled 

 above and externally, below with a dense, fanlike brush of 

 long hair scales, along rostral edge of brush hairs ciu-ved caudad. 

 (When the hindlegs are in rest, these brushes cover the venter almost 

 completely). Sometimes hind tibiae in male normal. Abdomen 

 sometimes (type species) with the third to fifth sternites modified, 

 dilated, with nvunerous small folds; apparently especially the third 

 sternite can be strongly expanded, with posteriorly, a dense fringe 

 of scent hairs or scales, especially along a median excision of posterior 

 edge; foiu-th sternite somewhat less extended and without hairs, 

 fifth with an additional bladder-like trapezoidal appendix with a 

 densely haired top. Sometimes abdomen almost normal, these ster- 

 nites only shghtly enlarged. In type species these sternites covered 

 with extremely large, oval, shining whitish scales. 



Forewing with vein 2 from beyond 2/3, 3 from angle, 4 closely 

 approximated, 7 separate, to termen, 8 and 9 closely approximated 

 at base, 11 from before middle. 



Hindwing with a cubital pecten, 2 from beyond middle, 3 and 4 

 connate from angle, 5 closely approximated, 6 and 7 closely approx- 

 imated towards base. 



Male genitaUa asymmetrical. Tegumen high, triangidar, its legs 

 (pedunculi) rather slender. Uncus clavate, slightly bilobed, mem- 

 branous and hairy, socius-like. Socii large, pending. Gnathos not 

 distinct. Left valva elongate, cucidlus with a narrow base; saccidus, 

 a separate, subquadrate lobe; harpe, a large rounded and flattened 

 pad, covered throughout with strong thorns; right processus dorsalis 

 large and prominent. Right valva much enlarged, right sacculus 

 many times larger than left, semioval; right cucullus long, pointed, 

 with a sheaf of very long bristles at the base extending beyond the
