99. reformata, n. Nigra, capite cano-iomeutoso, frontalibus fer- 

 rugineis, thorace cinereo, alis subcinereis, alulis albis, abdomine nigro- 

 aeneo subfusiformi. Long. 3 ; alar. 5^ lin. 



Frontalia very dark fei'ruginous ; bristles of the front descending to 

 nearly half the length of the face; epistoma pale testaceous, hardly 

 prominent ; lateralia red. Antennae nearly reaching the epistoma ; 

 third joint linear, rounded at the tip, almost twice the length of the 

 second; fifth long; sixth very minutely pubescent, stout along three- 

 fourths of tJie length, much longer than the third. Costal vein ending 

 at very little in front of the tip of the wing ; subcostal vein ending at 

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

 about half the length ; radial vein ending at a little beyond five-sixths 

 of the length ; cubital vein joining the costal at its tip ; praebrachial 

 vein forming an obtuse and much rounded angle at its flexure, between 

 which and its tip it is slightly curved inward ; discal transverse vein 

 slightly curved outward near its base, parted from the border by more 

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

 the praebrachial.
