Bristles of the front descending to three-fourths of the face ; rather 

 narrow; face vertical; facialia without bristles; epistoma not promi- 

 nent ; palpi black. Antenna almost reaching the epistoma ; second 

 joint nearly twice longer than deep ; third linear, rounded at the tip, 

 very much longer than the second; fourth very short; fifth rather 

 long ; sixth bare, stout for more than one-third of the length, twice 

 the length of the third. Costal vein ending at far in front of the tip 

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

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

 at three-fourths of the length ; cubital vein ending very near the tip of 

 the costal ; prasbrachial vein forming an obtuse angle at the flexure, 

 which emits a long branch, near this it is very slightly bent inward, 

 and is thence straight to the tip ; discal transverse vein much curved 

 inward behind the middle, parted by a little more than half its length 

 from the flexure of the praebrachial, and by a little less than its length

Frontalia luteous ; face vertical ; bristles of the front descending to 

 one-fourth of the length of the face ; facialia without bristles ; epistoma 

 prominent ; palpi black. Antennae black, almost reaching the epistoma ; 

 second joint thrice longer than deep ; third as long as the second, in-

 stout, bare, about twice the length of the third. Subcostal vein about
