prominent. Antennae 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 ; preebrachial 

 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 prajbrachial. Legs black.
