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

 about five-sixths of the length ; cubital vein ending very near the tip 

 of the costal; prsebrachial vein forming a very obtuse angle at its 

 flexure, very slightly curved inward near its tip ; discal transverse vein 

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

 flexure of the praBbrachial and from the border. Abdomen obconical ;

 nent. Antennas nearly reaching the epistoma ; second joint nearly 

 twice longer than deep ; third linear, slightly truncated, twice the 

 length of the second ; fourth and fifth short ; sixth bare, nearly twice 

 the length of the third. Thorax with four black stripes. Costal vein 

 ending at some distance in front of the tip of the wing ; subcostal vein 

 ending at one-third of the length ; mediastinal vein ending at a little 

 before half of the length ; radial vein ending at four-fifths of the length ; 

 cubital vein ending near the tip of the costal ; prasbrachial vein forming 

 a very obtuse angle at the flexure, nearly straight from thence to the 

 tip ; discal transverse vein with two slight curves, parted by nearly its 

 own length from the border, and by a little less from the flexure of the 

 prasbrachial.
