EXOPROSOPA. 197 



Museum, labelled " E. bimaculata, Macq."' in Bigot's handwriting. 

 Bigot evidently wrote bimaculata in mistake for binotata, but the 

 two specimens described above are certainly distinct from lar. In 

 the event of binotata, Macq., being a good species, they may be 

 representatives of it.

Head with frons more than twice as wide above antennae (where 

 it equals one-third the width of the head) as at vertex, blackish, with 

 black hairs on upper part, and below with black hairs mixed with a 

 number of short silvery scales of rather greater width ; face blach, 

 with black bristly hairs and small silver scales ; proboscis yellowish 

 brown ; antennae black, possibly sometimes reddish brown at base ; 

 occiput black, with small silvery scales at least near the eye- 

 margins, probably a considerable part of the surface thus covered 

 in perfect specimens. Thorax black ; dorsum with a dark indigo- 

 blue tinge, caused by the whole surface being covered in perfect 

 specimens with brilliant small subquadrate blue scales, longi- 

 tudinally striated, black pubescent; anterior margin with long; 

 narrow black scales ; bunches of similar scales or bristly hairs 

 below shoulders, on mesopleurae and ruetapleurae, and below hind 

 corners of dorsum ; apparently some black bristly or coarse hairs 

 around the wing-base. Scutellum black, covered with scales like 

 those of the thorax, pubescent, dull dark brown towards hind 

 margin, which bears a row of spines. Abdomen black, covered 

 with blue-green or green scales, with black pubescence; some 

 long, thin, very dark brown scales in a bunch at sides of 1st seg- 

 ment ; venter dark blackish indigo, with a little black pubescence 

 and no trace of scales. Legs black; fore tibia? and metatarsi 

 yellowish brown ; middle tibiae very dark brown ; hind femora 

 towards tips and hind tibiae from base to tip with rows of dense 

 long dark brown narrow scales. (No distinct bristles are visible 

 on the legs, but this may be due to the bad preservation of the 

 specimens.) Wings deep brown, violet-tinged, fore border about 

 the middle a little yellowish, also just a little paler about the 

 cross-veins ; tip of wing quite clear, limited by tip of 2nd longi- 

 tudinal vein, and hindwards on the wing-border by the proximal 

 side of the 2nd posterior cell.* Alulae and alar squamae fringed 

 with long narrow dark brown scales ; halteres blackish brown. 



Length, 11-18 mm. 



* In the second speciaien (from Karachi) the wing is pale along the hind 

 margin of the 3rd posterior cell.
