 ceived from T. R. Bell, Bombay, per H. E. Andrews, in Brit. 

 Mus. coll. 



A species allied to Tabanus joidus, Bigot, but distinguished 

 from it by the shining black thorax, and reddish 37ellow abdomen 

 with black apex, the under side identical. In shape of forehead 

 and frontal callus, colour of antennae, palpi and legs and of wings 

 it is very similar to the Bigot species. From Tabanus laotianus, 

 Bigot, from vSiam, it will differ in the colour of thorax, abdomen 

 and legs. Length iy\ mm., the other female 16 mm.

 black hairs, some yellow ones towards the apex, stout, ending in an 

 obtuse point. Antennae reddish yellow, the first two joints paler 

 with black pubescence, the third one broader at base than in 

 Tabanus joidus, with a distinct but small tooth. Forehead about 

 seven times longer than it is broad and a third narrower anteriorl}^ ; 

 frontal callus oblong, not reaching the eyes with a long linear ex- 

 tension, reddish brown, a large spot of the same colour on the ver- 

 tex, probably owing to denudation. r/zom% shining black, with 

 traces of yellowish brown tomentum anteriorh' and at the sides, 

 and on the dorsum as stripes, shoulders reddish and breast black, 

 both with the same coloured tomentum. Scutellum similar to 

 thorax. Abdomen reddish ^^ellow, somewhat shining, the fifth 

 partly, and the last two segments wholly, black, dorsum devoid of 

 pubescence ; under side identical but the black segments fifth and 

 sixth have distinct yellowish segmentations, hardly visible above, 

 some yellow and black pubescence on the under side. Legs black,
