 sexto ad apicem incrassato, alis sublimpidis, alulis albidis, abdomine 

 elongato-ovato. Long. 2 ; alar. 4 lin. 



Frontalia deep black ; bristles of the front descending along half the 

 face ; epistoma not prominent. Antennae almost reaching the epistoma ; 

 third joint sublinear, very deep, rounded at the tip, about thrice the 

 length of the second ; fifth long ; sixth stout to the tip, longer than the 

 third. Costal vein ending at very little in front of the tip of the wing ; 

 subcostal vein ending at a little beyond one-third of the length ; medi- 

 astinal vein ending at hardly beyond half of the length ; radial vein 

 ending at beyond five-sixths of the length ; cubital vein joining the 

 costal close to its tip ; prsebrachial vein forming an obtuse angle at its 

 flexure, hardly curved inward from thence to its tip ; discal transverse 

 vein with two hardly perceptible curves, parted from the border by a 

 little more than its length, and by more than its length from the flexure 

 of the prasbrachial.

 stoma somewhat prominent ; lateralia red ; palpi tawny. Antenna not 

 reaching the epistoma ; third joint broad, sublinear, rounded at the tip,

 half of the length ; radial vein ending at about seven-eighths of the

 forming a right but not sharply defined angle at its flexure, from whence 

 it is much curved inward to its tip ; prasbrachial transverse vein slightly
