bristles, and the scutellum bears a strong one on each side, nearly 

 as large as the apical pair. Abdomen yellow, with light yellow 

 pubescence ; 1st segment wholly black, the rest with a broad 

 black posterior margin (which is generally narrowest on the 2nd 

 segment) ; in the male this band is more or less of regular width, 

 but in the female it is generally enlarged in the middle to a suffi- 

 cient extent to attain the base of each segment, in some speci- 

 mens the colour spreading over the Avhole of the hinder segments. 

 Belly yellowish, blackish towards tip. Genitalia of male yellow, of 

 moderate size, second joint of claspers very slender ; in the female 

 the organs are inconspicuous, yellow. Legs wholly yellowish, 

 tibiae rather darker, tarsi blackish. Wings yellowish grey ; an 

 irregular, ill-defined, but distinct brownish arcuate band (its con- 

 vexity inwards) towards tip, crossing the 3rd and both branches 

 of the 4th longitudinal vein, and touching the tip of the 5th at 

 the wing-border. Halteres pale yellow. 



Lenqth 3 millim. 



Described from two males and ten females in the Indian 

 Museum, from Kurseong, Darjiling District, 5000 ft., 3-9. vii. 08,

 men in the Pusa Collection is from the Khasi Hills, Assam, 1000- 

 3000 ft., iii. 07. 



A very conspicuous species, and easily recognised from all 

 others in the genus or even subfamily, by the very large shining 

 black spots on the thorax. In one specimen from Bhowali, 

 Kumaon, taken by Mr. A. D. Imms in July 1909, the basal half 

 of the hind femora is black and the wing-marks almost absent. 

 Mr. Imms took it again at Bhowali on 28. vi. 10.
