EXOPEOSOPA. 197 



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

 Bigot evidently wrote himacidata in mistake tor hinotata, but the 

 two specimens described above are cei'tainly distinct from lar. In 

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

 representatives of it.

Head with Irons more than twice as wide above anteunse (whei-e 

 it equals one-third the width of the tiead) 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 black, 

 with black bristly hairs and small silver scales ; proboscis yellowish 

 brown ; antenna? 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 ; buuches of similar scales or bristly hairs 

 below shoulders, on mesopleurse and metapleura?, and below hind 

 corners of dorsum ; apparently some black bristl}' or coarse hairs 

 around tlie 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 tibiae and metatarsi 

 yellowish brown ; middle tibise very dark brown ; hind femora 

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

 long dark brown narrow scales. (Xo 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 Und posterior cell.* Alula? and alar squamae fringed 

 with long narrow dark brown scales ; halteres blackish brown. 



Lengtli, 11-18 mm. 



* In the second specimen (from Karachi) the wing is pale along the bind 

 margin of the 3rd posterior cell.
