52 MUSCID^E. 



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

 of the length of the face; epistoma not prominent. Antennae not 

 reaching the epistoma ; third joint sublinear, almost truncated at the 

 tip, much longer than the second ; sixth stout for full half the length, 

 more than twice the length of the third. Costal vein ending at some 

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

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

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

 length; cubital vein joining the costal almost close to its tip; prae- 

 brachial vein forming a very obtuse angle at its flexure, straight from 

 thence till near its tip, where it is very slightly inclined inward ; discal 

 transverse vein with two distinct curves, parted from the border by much 

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

 flexure of the praebrachial.

Frontalia deep Hack, linear ; bristles of the front descending to one- 

 third of the face ; face vertical ; facialia bristly to one-third of the 

 length ; epistoma not prominent ; eyes bare. Antennae nearly reaching 

 the epistoma ; second joint nearly twice longer than deep ; third linear,

 border ; mediastinal vein ending at a little beyond half of the border ; 

 radial vein ending at four-fifths of the border ; cubital vein ending very 

 near the tip of the costal ; praebrachial vein forming a very obtuse angle 

 at the flexure, nearly straight from thence to the tip ; discal transverse
