TACHINA. 77 



ending at about live-sixths of the length; cubital vein ending at near 

 the tip of the costal ; praebrachial vein forming an obtuse angle at its 

 flexure, straight from thence to near its tip, where it is very slightly in- 

 clined inward ; discal transverse vein nearly straight, parted by a little 

 less than its length from the flexure of the praebrachial, and by much 

 less from the border. 



Rare. In the late Mr. Stephens' s collection. (E.) 



132. denotans, n. Nigra cano-tomentosa, capite albo, an tennis 

 basi palpisque testaceis, thorace nigro-quadrivittato, alis subcinereis, 

 alulis albidis, abdomine longi-obconico subcylindrico, pedibus fulvis, 

 tarsis nigris. Long. 3 ; alar. 5 lin. 



Head testaceous in front. Frontalia reddish, slightly depressed, 

 widening much in front ; bristles of the front not extending along the 

 face ; facialia without bristles ; epistoma rather prominent. Antenna 

 not reaching the epistoma ; third joint linear, rounded at the tip, much 

 longer than the second ; sixth plumose, with rather long hairs, thick at 

 the base, more than twice the length of the third. Thorax with four 

 interrupted black stripes. Costal vein ending a little in front of the tip 

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

 length ; mediastirial vein ending at about half the length ; radial vein 

 ending at much beyond three-fourths of the length; cubital vein 

 joining the costal almost at its tip; praebrachial vein forming an 

 obtuse, and not sharply defined angle at its flexure, from whence it 

 is very slightly inclined inward to its tip, which joins the cubital vein 

 almost at the tip of the latter ; discal transverse vein with two very 

 slight curves, parted from the border by very little less than its length, 

 and by much more than its length from the flexure of the praebrachial. 



Rare. (E.) 



133. contempta, n. Nigra, cano-tomentosa, capite albo, thorace 

 nigro-trivittato, alis subcinereis, alulis albis, abdomine ovato tessellato. 

 Long. 2^; alar. 5 lin. 



Frontalia with grey tomentum ; bristles of the front descending to 

 one-third of the face ; facialia without bristles ; epistoma slightly pro- 

 minent. Antennas not reaching the epistoraa; third joint broad, 

 straight above, convex beneath, oblique at the tip, very much longer 

 than the second ; sixth pubescent, stout towards the base, much more 

 than twice the length of the third. Thorax with three black stripes. Cos- 

 tal vein ending where the praebrachial meets it, far in front of the tip 

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

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

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

 costal; praebrachial vein forming a right angle at its flexure, which 

 emits a long branch ; near this it is curved inward, and is thence 

 almost straight to its tip ; discal transverse vein with the two usual 

 curves, which are extremely slight ; it has also a short outward curve
