Frontalia distinctly striated ; bristles of the front descending to one- 

 third of the face ; facialia without bristles ; epistoma not prominent ;

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

 mediastinal vein ending at a little beyond half the length ; radial vein 

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

 costal near its tipj prsebrachial vein forming a very obtuse and not 

 sharply defined angle at its flexure, beyond which it is almost straight, 

 but is very slightly curved inward towards its tip ; discal transverse 

 vein with two extremely slight curves, parted from the border and from
