Frontalia widening in front ; bristles of the front descending to half 

 the length of the face ; face vertical ; facialia bristly to half the length ; 

 epistoma not prominent ; paljn hlacJc. Antenui3e not reaching the epi- 

 stoma; second joint a little longer than deep; third linear, truncated, 

 twice the length of the second ; fourth indistinct ; fifth very short ; 

 sixth bare, stout to half the length, nearly twice the length of the third ; 

 thorax tclth three hlach stripes. Costal vein prominent as far as the tip 

 of the subcostal, where it is armed with a spine, ending at a little in 

 front of the tip of the wing ; subcostal vein ending at much beyond 

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

 of the length ; radial vein ending at five-sixths of the length ; cubital 

 vein ending very near the tip of the costal ; preebrachial vein forming 

 a right angle at the flexure, which emits a very short branch, much 

 curved inward between this and the tip ; discal transverse vein curved 

 inward, parted by less than its length from the border, and by very 

 much more than its length from the flexure of the prsebrachial.

 radial vein ending at about five-sixths of the length ; cubital vein join-

 the latter ; discal transverse vein with two very slight curves, parted 

 by vei-y much more than its own length from the border and from the
