Frontalia dull black ; bristles of the front descending to one-eighth 

 of the face ; facialia without bristles ; epistoma not prominent ; eyes 

 bare; palpi tawny. Antennae not reaching the epistoma; third joint 

 about twice longer than broad, rounded at the tip, a little longer than

 more than twice the length of the third. Costal vein ending a little 

 above the tip of the wing ; subcostal vein ending at about one-third of 

 the length ; mediastinal vein ending before half the length ; radial 

 vein ending at much beyond three-fourths of the length ; cubital vein 

 joining the costal very near its tip ; prasbrachial vein forming a very 

 obtuse but sharply-defined angle at its flexure, almost straight from 

 thence to its tip, which joins the cubital near the tip of the latter ; 

 discal transverse vein with two very slight curves, parted by hardly 

 less than its length from the flexure of the praebrachial and from the 

 border. Var. /3, discal transverse vein emitting a short branch on the 

 inner side.
