near which it is slightly curved inward, and is thence almost straight 

 to its tip ; discal transverse vein with two extremely slight curves, 

 parted from the border by its length, and by much less than its length 

 from the flexure of the prsebrachial.

Frontalia deep black, linear ; bristles of the front descending to one- 

 third of the face ; face vertical ; epistoma not prominent. Antennae 

 reaching the epistoma ; second joint not longer than deep ; third linear, 

 subtruncated, four times the length of the second ; fourth almost obso- 

 lete ; fifth very short ; sixth bare, stout for more than one-third of the 

 length, much less than twice the length of the third ; thorax with three 

 slender hlach stripes. Costal vein ending at some little distance in front 

 of the tip of the wing ; subcostal vein ending at a little beyond one- third 

 of the length ; mediastinal vein ending at beyond half of the length ; 

 radial vein ending at beyond four-fifths of the length ; cubital vein 

 ending very near the tip of the costal ; pra3brachial vein forming an 

 obtuse angle at its flexure, hardly curved inward from thence to its tip ; 

 discal transverse vein straight, with the exception of an indistinct 

 hinder inward curve, parted by hardly more than its length from the 

 flexure of the prpebrachial, and by hardly less from the border,

Frontalia deep black ; bristles of the front descending nearly to half 

 the length of the face ; epistoma not prominent ; lateralia partly red. 

 Antennas reaching the epistoma ; third joint linear, slightly rounded at 

 the tip, more than four times the length of the second ; sixth very mi- 

 nutely pubescent, stout for one-third of the length, nearly twice the 

 length of the third. Costal vein ending at some distance in front of 

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

 length ; mediastinal vein ending at hardly half the length ; radial 

 vein ending at about four-fifths of the length ; cubital vein joining 

 the costal very near its tip ; prcehrachial vein forming an almost right 

 angle at its flexure, from whence proceeds a slight clouded streak ; be- 

 tween this and its tip it is very slightly curved inward ; discal trans- 

 verse vein with the hind curve much deeper and longer than the other, 

 which is hardly perceptible, parted from the border by much more
