t alia ferruginous ; facialia bristly for one-fourth of the length ; epistoma 

 not prominent ; lateralia red. Antennas nearly reaching the epistoma ; 

 third joint linear, rounded at the tip, full thrice the length of the 

 second ; arista stout for half the length from the base, near twice the 

 length of the third. Costal vein ending at some little distance in front 

 of the tip of the wing ; subcostal vein ending at a little before one- 

 third of the length ; rnediastinal vein ending at about half the length ; 

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

 ing the costal very near its tip ; prasbrachial vein forming a slightly 

 obtuse angle at its flexure, between which and its tip it is hardly curved 

 inward ; discal transverse vein with two extremely slight curves, emit- 

 ting a short branch inward near the hind end, parted from the hind 

 border by a little more than its length, and by much less than its length 

 from the flexure of the prsebrachial.
