384 E- Brunetti : Azotes on Oriental Diptera. [VOL. I, 



very small with some long bristles ; back of head grey, with a 

 single row of small bristles round the eye border. In the female 

 the front equals one third the width of the head, silvery grey, 

 with a quadrate black spot, sometimes appearing as a thick V, 

 just above the antennae ; on either side of this spot is a vertical 

 row of four bristles. 



Thorax — 



Ash-grey, lower part rather more whitish, a deep black 

 broad stripe runs transversely across the dorsum from the wing- 

 insertions, and a narrower one immediately in front of the scutel- 

 lum. The disposition of bristles is not quite consistent, but 

 seems to be as follows : a lateral row of- three large ones on the 

 humeral limit of the dorsum ; a transverse row of eight bristles 

 immediately in front of the transverse black stripe, of which the 

 two centre ones are smaller than the rest ; a row of six then 

 follows, and in front of these again, a rather irregular row of quite 

 small ones of va.rying number ; three or four occur on the black 

 stripe, and between it and the scutellum are ten or twelve others. 

 The unicolorous scutellum bears a few short ones and two long 

 ones at the tip which cross one another ; a row of five bristles in 

 front of each wing-insertion with three or four behind ; meta- 

 notum whitish grey, bare. 



A hdomen — 



Whitish grey ; at the base of the second, third and fourth 

 segments a narrow black band which is produced downwards in 

 the form of three triangles, the centre ones being longest and 

 narrowest, the outer ones not reaching the posterior border, nor 

 the side margins. A row of bristles on posterior edge of each 

 segment, the dorsum of which is covered with scattered hairs. 

 Belly grey. 



Legs— 



Black ; femora with a row of bristly hairs on outer and 

 under sides, longest on fore pair ; four posterior tibise with a few 

 scattered bristles. Hind femora curved, a' ? . 



Wings — 



Pale grey, with the slightest yellowish tint towards base and 

 foreborder ; alulae whitish, lower scale slightly the larger ; halteres 

 pale yellow. 



Described from six males and four females in the Indian 

 Museum collection, from Calcutta, May 1907, Mhow (India), nth 

 to i6th April 1905, Hongkong, 5th March 1906, and from further 

 specimens of both sexes from Mhow and Hongkong in my own 

 collection, the specimens from these two localities having been 

 taken by me.
