subserrulate, simple, scape moderately elongate, Avith a tuftlike 

 small pecten toward apex, in female antenna slender, scape without 

 pecten. Labial palpus long, recurved, median segment moderately 

 thickened with appressed scales, forming a small roughish tuft at 

 apex above, terminal segment shorter than median, rather slender, 

 acute. Maxillary palpus small, scaled, appressed to proboscis. 

 Thorax ^^-ithout a crest. Posterior tibia thickened with smoothly 

 appressed scales. 



Forewing suboval, short-pointed. Vein la strong, long-furcate at 

 base, 2 and 3 stalked from angle, 4 and 5 approximated to each other 

 at base, 6 to termen, 7 absent, 8 to apex, 9 moderately approximated at 

 base, 11 from middle. 



HindAnng shghtly over 1, cilia 3/4, trapezoidal, without cubital 

 pecten. Vein 2 from before 3/4, 3 and 4 very short-stalked, 5 shghtly 

 submedian, parallel, 6 and 7 connate. 



Male genitaha with tegumen triangular, uncus strong wdth a dilated 

 top, gnathos normal. Valva triangular, rather broad, with a tri- 

 angular knob at base of costa. Anellus lobe broad and rounded. 

 Saccus rather short. Aedeagus cm-ved, moderate, mthout cornuti. 



Female genitaha wdth ovipositor large, cylindrical, apophyses 

 moderate. Ostium, a small cup. Ductus biu-sae tortuous. Corpus 

 biu-sae inverted pear-shaped. Signa, tw^o separate stellate sclerites. 



Type species: Hypodrasia acycla, new species (cf9). 



A peculiar form, probably of Brachmia gi"oup, but not fitting in 

 any of the described genera. Perhaps it is closest to Pachnistis 

 Meyrick, differing by separate veins 8 and 9, and the presence of a 

 pecten of the antenna (in male only).
