below antennae. Frons rich brownish-orange, vertex with a little 

 more yellowish tinge, both with minute black hairs; ocellar 

 triangle exceedingly small, barely raised above the surface. Facial 

 triangle quite prominent and flat, pale yellowish, blackish towards 

 tip. A narrow tomentose stripe on inner side of eyes from vertex 

 to lower corner of eye, gradually widening from top to bottom, but 

 when viewed from behind the whole of the sides of the face appear 

 uniforml}^ yellowish ; the space between this stripe and the facial 

 triangle brownish- orange as the frons. Mouth border narrowly 

 black. Proboscis large, completely filling mouth opening, much 

 swollen at tip, side view triangular, yellowish, labella and palpi 

 concoloroLis ; former with a little yellow pubescence, latter two- 

 jointed, about as long as the 3rd antennal joint, elongo cylindrical, 

 with a few hairs. Antennal ist joint very short, 2nd distinctly 

 longer than wide, both reddish-brown, with some small black 

 biistles on upper side ; 3rd joint ovate-conical with narrower 

 rounded tip, bare, blackish, reddish-brown at base, arista rather 

 long, basal, black, apical half plumose above and below. 



Eyes oblong, twice as high as wide ; occiput flush with vertex 

 on upper half, much swollen posteriorly on lower half, almost 

 equal in width to the eye ; wholly brownish-yellow. 



A single pair of post- vertical strong bristles towards corners 

 of eyes, and a pair of oral vibrissae. 



Thorax deep metallic indigo-blue, the surface studded with 

 almost microscopic tubercles, from each of which two or three short 

 stiff brownish-yellow hairs emerge. Sides of thorax and scutellum 

 of a similar nature, latter with a row of several bristles on posterior 

 margin. Humeral calli yellowish-brown, bare, a small similar dark 

 brown callus bearing a single spine, at each end of the transverse 

 suture. 



Abdomen much curved downwards; shining metallic deep 

 blue, studded with hair-bearing tubercles as the thorax. Belly 

 mainly yellowish in centre. Genitalia deep blue, small, cylin- 

 drical, with a telescopic yellow interior piece. 



Legs. — Fore coxae long, slender, smooth, shining, twice as 

 long as posterior ones, the latter a little pubescent ; fore femora 

 with a row of 8 or 10 small spines on underside, extending nearly 

 its entire length. Legs all blue-black, microscopically pubescent; 

 pulvilli yellow. 



Wings. — Ground colour pale grey ; dark brown from anterior 

 border to 5th longitudinal vein, and distally from base to the 

 upturned section of the 5th vein, the colour thence rather sharply 

 delimited in an oblique line to the anterior margin ; the costa 

 broadly brown to the tip, but sometimes this apical section of the 

 brown colour is cut off from the remainder by a very narrow clear 

 space. Beyond the middle of the wing a large semicircular spot 

 on costa, extending nearly as far backwards as the 4th longitudi- 

 nal vein, and more yellowish in front. Halteres blackish. 



Described from a single specimen in good condition amongst 

 Lord Carmichael's Diptera from Ghumti, 4000 ft., August, 1912,
