81. expleta, n. Nigra, cano-tomentosa, capite albo, facialibus 

 ad dimidium setosis, thorace nigro-quadrivittato, alis subcinereis, alulis 

 albis, abdomine obconico tessellato. Long. 3 ; alar. 7 lin. 



Frontalia deep black; bristles of the front descending to half the 

 length of the face; face slightly oblique; facialia beset with bristles 

 along half tJie length; epistoma not prominent; lateralia red. An- 

 tennee reaching the epistoma; third joint linear, slightly rounded at 

 the tip, hardly more than twice the length of the second ; sixth stout 

 till near the tip, very much longer than the third. Costal vein ending 

 where the praebrachial meets it at some distance in front of the tip of 

 the wing ; subcostal vein ending at much beyond one-third of the 

 length ; mediastinal vein ending at much beyond half of the length ; 

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

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

 obtuse angle, near which it is very slightly curved inward, and is thence 

 straight to its tip ; discal transverse vein with two slight curves, parted 

 from the border by more than its length, and by much less than its 

 length from the flexure of the praebrachial.

Frontalia piceous, broad, linear ; bristles of the front descending to 

 one-third of the face ; face vertical ; facialia bristly for two-thirds of 

 the length; epistoma not prominent; palpi tawny towards the tips. 

 Antennae not reaching the epistoma ; second joint a little more than 

 twice longer than deep ; third sublinear, rounded at the tip, somewhat 

 longer than the second; fourth very short; fifth short; sixth very 

 minutely pubescent, stout for more than one-third of the length, very 

 much longer than the third. Costal vein ending at far 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 four-fifths of the length ; cubital vein ending near the tip of 

 the costal ; prcebrachial vein forming an obtuse angle at the flexure, 

 which emits a short branch, very slightly curved inward near this, and 

 thence straight to the tip ; discal transverse vein with two very indis- 

 tinct curves, parted by much less than its length from the flexure of 

 the praebrachial, and by very much more than its length from the border.
