prominent. Antennas reaching the epistoma ; third joint linear, slightly 

 oblique and almost truncated at the tip, about four times the length of 

 the second ; sixth pubescent, stout at the base, very much longer than 

 the third. Costal vein ending at the tip of the wing ; subcostal vein 

 ending before one-third of the length ; mediastinal vein ending at much 

 before half the length ; radial vein ending at about five-sixths of the 

 length ; cubital vein joining the costal very near its tip ; prsebrachial 

 vein forming a very obtuse and not sharply defined angle at its flexure, 

 from whence it is almost straight till near its tip, where it is slightly 

 inclined inward ; discal transverse vein with two distinct curves, parted 

 from the border by hardly more than half its length, and by a little 

 less than its length from the flexure of the prsebrachial. Legs black.

 Antennas reaching the epistoma; second joint red, not longer than 

 deep ; third sublinear, slightly truncated, about six times the length of 

 the second ; fourth very short ; fifth distinct ; sixth bare, thick for less 

 than half the length, very much longer than the third. Costal vein

 ending at about one-third of the length ; mediastinal vein ending at 

 beyond half the length ; radial vein ending at a little beyond three-

 vein forming an obtuse angle at its flexure, near which it is very

 transverse vein with two very distinct curves, parted by very little less 

 than its own length from the flexure of the prasbrachial, and by much 

 less from the border. Legs tawny.
