Leptopeza vitripennis, Brunetti, Rec. Ind. Mus. ix, p. 31 (1913). 



S 5 . Head blackish ; proboscis horizontal, as long as length of 

 head ; shining black ; palpi short, porrect, black ; antenna? with 

 elongate conical 3rd joint, arista long, black. Thorax very highly 

 arched, shining black in middle of dorsum, with short whitish 

 hairs laterally. Abdomen shining black, with short whitish 

 pubescence ; venter similar. Legs rather pale pitch-brown, a 

 little pubescent. Wings very clear and iridescent ; halteres black.

Described from a type S from Oncha Gaon, JNaina Tal Distr.,

Subfamily HEMERODROMIIN^E. 



Head with eyes separated in both sexes, frons sometimes nar- 

 rower in (S ; eyes sometimes contiguous below; when this is so, 

 frontal facets larger than the others ; eyes sometimes pubescent. 

 Proboscis short, not- louger than height of head ; palpi 1- or 

 (indistinctly) 2-jointed. Antenna? 3-jointed, with, in some genera, 

 a 2-jointed stjde which may be aristiform ; one or two excep- 

 tions occur. Thorax longer than broad, but slightly arched ; 

 metapleura bare, with short hairs or a few bristles. Legs with 

 fore coxa? always lengthened, sometimes about as long as femora, 

 always longer than posterior coxae. Pore femora often incrassate 

 and fore legs often raptorial. Wings cuneiform at base, the 

 axillary lobe being greatly reduced or absent ; 3rd longitudinal 

 vein simple or forked ; 4th vein forked ; lower branch of 5th vein 

 may be distinctly recurrent, or placed perpendicularly to hind 

 margin of wing, or absent. Pour posterior cells ; discal cell 

 present or absent; basal cells more or less subequal ; anal cell 

 longer or shorter than 2nd basal cell, or absent; anal vein of 

 varying length or absent ; squama? absent. 



The cuneiform wings and much elongated fore coxa? will easily 

 distinguish members of this subfamily. Many of the yellowish 

 forms of Empid.e belong to it.
