much longer than the third. Costal vein ending on the fore border at 

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

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

 vein forming an obtuse angle at its flexure, between which and its tip 

 it is slightly curved inward ; discal transverse vein with two very indis- 

 tinct curves, parted from the border by much more than its length, and 

 by a little less than its length from the flexure of the praebrachial. 

 Rare. (E.) 



141. amabilis, Meig. Zw. iv. 374. 232 (1824). Nigra, cano-to- 

 mentosa, capite albo, antennarum articulo sexto ad trientem incrassato, 

 thorace nigro-quadrivittato, alis subcinereis, alulis albidis, abdomine 

 longi-ovato tessellato. Long. 2f ; alar. 5 lin. 



Frontalia deep black, broad, linear ; bristles of the front descending 

 to three-fourths of the face; face oblique; epistoma not prominent. 

 Antennae reaching the epistoma ; second joint not longer than deep ; 

 third linear, slightly truncated, six times the length of the second ; 

 fourth and fifth very short ; sixth bare, stout for one-third of the length, 

 longer than the third. Costal vein ending at far in front of the tip of 

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

 mediastinal vein ending at half of the length ; radial vein ending at 

 four-fifths of the length ; cubital vein ending near the tip of the costal ; 

 praebrachial vein forming a hardly obtuse angle at the flexure, which 

 emits a long indistinct branch, curved inward near this ; discal trans- 

 verse vein with two indistinct curves, parted by its length from the 

 flexure of the prsebrachial, and by much more from the border. 



Rare. In Mr. Desvignes's collection. (E.) 



142. campestris, Fal. Msc. 8. 12 (1810); Meig.; Mcq. ; Zett. 

 Nigra, cinereo-tomentosa, capite porrecto albo, facialibus ad dimidium 

 setosis y alis subcinereis, aluh's albidis, abdomine obconico tessellato. 

 Long. 2f-3 ; alar. 4^-5 lin. 



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

 the face ; face oblique ; facialia bristly for half the length ; epistoma 

 slightly prominent. Antennae reaching the epistoma ; third joint linear, 

 rounded at the tip, about sixth times the length of the second ; sixth 

 microscopically pubescent, stout for more than half the length from the 

 base, a little longer than the third. Costal vein ending at some 

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

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

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

 cubital vein joining the costal very near its tip ; prajbrachial vein 

 forming a very slightly obtuse angle at its flexure, near which it is curved 

 inward, and is thence almost straight to its tip ; discal transverse vein 

 with two very slight curves, parted from the border by very much
