slightly curved inward from thence to the tip ; discal transverse vein 

 with two indistinct curves, parted by much less than its length from 

 the flexure of the prsebrachial and from the border. Abdomen ellip-

 tibus, thorace nigro-quadrivittato, alis cinereis, alulis albis. Long. 3 ; 

 alar. 6 lin. 



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

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

 nent ; palpi black. Antennas 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 prasbrachial, and by a little less than its length 

 from the border. Abdomen long, obconical ; base, tip, dorsal stripe,

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

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

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

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

 creasing in breadth from the base to the tip, which is truncated ; sixth 

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

 one-third of the length of the wing ; mediastinal vein about 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 form-

 branch, beyond this it is very slightly inclined inward, and is thence 

 almost straight to its tip ; transverse veins slightly clouded with brown ; 

 discal transverse vein almost straight, excepting a^ slight outward curve
