ure, near which it is hardly curved inward, and is thence almost straight 

 to its tip ; discal transverse vein with two very indistinct curves, parted 

 from the border by very much more than its length, and by little less 

 than its length from the flexure of the pra3brachial.

 Long. 3 ; alar. 6 lin. 



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

 of the face; face very oblique; epistoma not prominent. Antennae 

 reaching the epistoma ; third joint linear, truncated but rounded be- 

 neath at the tip, full thrice the length of the second ; sixth stout for 

 more than half the length from the base, very much longer than the 

 third. Costal vein ending on the fore border at some little distance 

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

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

 vein ending at a little beyond three-fourths of the length ; cubital vein 

 joining the costal near its tip ; prabrachial vein forming a very obtuse 

 angle at its flexure, from whence it is nearly straight to its tip ; discal 

 transverse vein with two very slight curves, parted from the border by 

 more than its length, and by less than its length from the flexure of 

 the prsebrachial.

Frontalia deep black, broad, linear ; bristles of the front descending 

 beyond one-third of the face ; face vertical ; facialia bristly for more 

 than one-third of the length ; epistoma not prominent ; lateralia red ; 

 eyes bare. Antenna reaching the epistoma ; second joint nearly twice 

 longer than deep ; third linear, slightly truncated, nearly thrice the 

 length of the second ; fourth very short ; fifth rather long ; sixth stout 

 for three-fourths of the length, longer than the third. Costal vein 

 ending at far in front of the tip of the wing ; subcostal vein ending at 

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

 little before half of the border ; radial vein ending at three-fourths of 

 the border ; cubital vein ending very near the tip of the costal ; pra3- 

 brachial vein forming an obtuse angle at the flexure, which emits a very 

 short branch, hardly curved inward from thence to the tip; discal 

 transverse vein almost straight, parted by nearly its length from the 

 flexure of the praebrachial, and by much more than its length from the 

 border.
