 fore wing is not angular below vein 2, and the terminal margin 

 of the hind wing is entire, not scalloped, with a comparatively 

 shorter tail and smaller tornal lobe. The venation of the wings 

 is quite different. Cell of fore wing broad, not quite half length 

 of wing entirely closed ; upper discocellular very short, middle 

 deeply concave, very little shorter than lower, lower concave; 

 veins 3 and 4 from lower apex of cell ; 8 and 9 out of 7, latter 

 emitted much closer to base of 7 than in Ifhinopalpa ; 10 and 11 

 free, emitted as in BTxinopalpa but much shorter. Hind wing : 

 cell slenderly closed, short, much less than half length of wing ; 

 veins 3 and 4 stalked, vein 6 a very little closer to vein 7 than to 

 vein 5. Antennas and palpi much as in Bhinopalpa, the former 

 proportionately somewhat shorter ; eyes naked.
