TACHINA. 69 



epistoma; third joint linear, slightly rounded at the tip, much more 

 than twice the length of the second ; sixth minutely pubescent, stout 

 for one-third of the length, much more than twice the length of the 

 third. Costal vein ending at a little in front of the tip of the wing ; 

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

 astinal vein ending at half the length ; radial vein ending at about four- 

 fifths of the length ; cubital vein joining the costal near its tip ; pra- 

 brachial vein forming a right angle at its flexure, which emits a very 

 short clouded branch, near this it is much curved inward, and is thence 

 straight to its tip ; discal transverse vein with two rather deep curves, 

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

 half its length from the flexure of the prsebrachial. 

 Rare. (E.)

 of the antennae ; bristles of the front descending to beyond half of the 

 length of the face ; face vertical ; epistoma not prominent ; eyes bare ;

 second joint a little longer than deep, tawny at the tip ; third linear, 

 slightly truncated, about thrice the length of the second ; fourth very 

 short ; fifth moderately long ; sixth bare, stout for half the length, very 

 much longer than the third. Costal vein convex as far as the subcostal, 

 ending at very little above the tip of the wing ; subcostal vein ending 

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

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

 the length ; cubital vein bristly at the base, ending at near the tip of 

 the costal; pr&brachial vein forming a slightly obtuse angle at the flex- 

 ure, slightly curved inward from thence to the tip; discal transverse 

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

 flexure of the pra3brachial, and by rather less from the border. 



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