yellow spots, their apices not contiguous, but connected by a small 

 grey dusted patch. The 3rd band is actually interrupted for a 

 very short space and in individual specimens might easily resolve 

 itself into two elongate spots. Pubescence of abdomen con- 

 colorous with ground colour ; a good deal of white hair laterally at 

 the base and short pubescence along the side margins except 

 where the black parts of the abdomen intervene. Belly blackish, 

 the two wider yellow bands duplicated as on the dorsum, the 

 pubescence sparser. In certain lights the dorsal abdominal bands 

 have a cream3^ shade, especially the ist band. 



Legs. — Coxae rather less than half as long as the anterior 

 femora, and more than half the hind femora, black. Tibiae brown- 

 ish yellow, tarsi brown or blackish brown, hind pair with golden 

 brown pubescence below. Femora with pale hair, hind tibiae with 

 minute black pubescence on outer side. 



Wings clear, subcostal cell pale yellow; halteres yellowish 

 white. 



Described from one 2 from Sadiya, 28-xi-ii. 



Syrphus fulvifacies, mihi, sp. nov. 



9 N.E. Frontier of India. Long. 9 mm. 



Head. — Eyes bare; frons twice as wide at the level of the 

 antennae (where it forms one third of the head) as at the vertex; 

 wholly dull black, but for a short space below the black vertical 

 triangle and also above the antennal protuberance it has a brassy 

 aenous tinge. From the vertex to the antennae with black hairs. 

 Face wholly, from roots of antennae downwards to lower margin, 

 bright golden orange, rather deeper on central knob, which is of 

 moderate size; mouth black but the mouth border itself yellow, 

 with a small black spot at the extreme tip of the snout. Proboscis 

 dark brown. Face with a little short black pubescence on sides 

 of protuberance, on the remainder with ver}* soft pale yellow 

 hairs. Antennae dull black, basal two-thirds of underside of 3rd 

 joint dull reddish brown, arista black. Occiput gre}' with a 

 complete marginal fringe all round of uniformly sized bright 

 yellow scale-like thick hairs. 



Thorax. — Dull blackish, with soft pale brownish yellow hairs. 

 These are so sparsely placed and of such fineness that the dorsum 

 appears at first sight denuded of pubescence except towards the 

 lateral margins and at the sides, where it is bright golden yellow 

 and much thicker both in texture and quantit}^ The pleurae and 

 wing bases also covered with similar, golden yellow hair ; sides of 

 thorax cinereous grey. Scutellum yellow, with rather copious long 

 black pubescence. 



Abdomen. — Ovate, black. A pair of elongate yellow spots in 

 the centre of the lateral margins of 2nd segment, their inner ends 

 rounded but well separated from one another. A yellowish band in 

 the middle of the 3rd and 4th segments, their anterior corners onl}^ 

 reaching the lateral margins. These bands are emarginate in the
