58 MUSCIDvE. 



much beyond one-third of the length ; mediastinal vein ending at very 

 much beyond half of the length ; radial vein ending at beyond seven- 

 eighths of the length ; cubital vein joining the costal very near its tip ; 

 prsebrachial vein forming a slightly acute but much rounded angle at 

 its flexure, between which and its tip it is much curved inward ; discal 

 transverse vein with two hardly perceptible curves, parted from the 

 border by hardly half its length, and by little more than half its length 

 from the flexure of the prsebrachial. 

 Not common. (E.) 



88. fimbriata? Meig. Zw. iv. 337. 168 (1824). Nigra, cano-to- 

 mentosa, capite albo, thorace nigro-quadrivittato, scutello nigro, alis sub- 

 cinereis, alulis albis, abdomine obconico tessellato. Long. 3; alar. 6 lin. 



Frontalia deep black ; bristles of the front descending to one-fourth 

 of the face ; epistoma not prominent. Antenna3 reaching the epistoma ; 

 third joint linear, rounded at the tip, about thrice the length of the 

 second ; sixth very minutely pubescent, very much longer than the 

 third. Scutellum black. Costal vein ending at some distance in front 

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

 length ; mediastinal vein ending at a little before half the length ; 

 radial vein ending at about four-fifths of the length ; cubital vein slightly 

 undulating, joining the costal very near its tip ; prsebrachial vein form- 

 ing an obtuse angle at its flexure, between which and its tip it is very 

 indistinctly curved inward ; discal transverse vein with two distinct 

 curves, parted from the hind border by a little more than its own length. 



Not common. (E.) 



89. flexa, n. Nigra, cano-tomentosa, capite albo, palpis apice fid- 

 vis, thorace nigro-quadrivittato, alis cinereis, alulis albis, abdomine ovato, 

 vitta dorsali et segmentorum marginibus posticis nigris. Long. 3 ; alar. 

 6 lin. 



Frontalia deep black, linear ; bristles of the front descending to one- 

 third of the face ; face vertical ; epistoma not prominent ; palpi tawny 

 towards the tips. Antenna reaching the epistoma ; second joint full 

 twice longer than deep ; third linear, rounded at the tip, reddish at the 

 base, nearly twice the length of the second ; fourth indistinct ; fifth 

 short ; sixth bare, stout for one-third of the length, twice the length of 

 the third. Costal vein ending at a short 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 beyond half of the length ; radial 

 vein ending at much beyond five-sixths of the length; cubital vein 

 ending very near the tip of the costal ; prsebrachial vein forming a 

 slightly obtuse and not sharply-defined angle at its flexure, very slightly 

 curved inward from thence to its tip ; discal transverse vein much 

 curved inward behind the middle, parted by its length from the flexure 

 of the pra3brachial, and by much less than its length from the border.
