on the exterior border of each segment. Legs black, with yellow- 

 ish tomentum. From East India (M. ]\Iarc) Museum. An identi- 

 cal specimen in my collection came from Java. ^lacquart, Dipt, 

 exot., i, p. 132. 



Type 9 (the one from India I believe) seen by me in Paris 

 ]^Iuseum. A medium-sized species distinguished from Tabanus 

 interniis, Wlk., with wdiicli I compared it, by the narrower forehead 

 and frontal callus and by the spots on abdomen which are al- 

 most hemispherical in shape, on the second to fifth segments, small 

 and oblong on the sixth, abdomen dark brown in colour, the seg- 

 mentations very narrowly yellowish, and the lateral margins more 

 wideh' so, forming the spots mentioned by Macquart; underside 

 brown with A^ellowish segmentations and yellow pubescence on them. 



Wings clear, tinged browai. Legs brownish, tibiae appearing 

 obscurely reddish on middle and posterior legs. Forehead narrow, 

 eight or more times as long as it is broad, narrower anteriorly, 

 with a long narrow frontal callus and lineal extension. Antennae 

 reddish brow^n, palpi rather broad, brownish yellow with black 

 pubescence. Face with yellowish white pubescence. Beard the 

 same colour. 



This is apparently a distinct species, distinguished by the 

 almost wdiolly black legs, dark palpi and antennae and b}^ the 

 hemispherical spots of the dark blackish brown abdomen.

A somewhat variable species, in colouring, but distinguished 

 by the extreme narrowness of forehead, becoming anteriorly onl}' 

 half the width of what it is at vertex. The abdomen varies from 

 reddish yellow anteriorly, becoming darker at apex (type), to dark 

 reddish brown with small median indistinct spots, sometimes not 

 apparent, the black pubescence on dorsum always rather thick, 

 sides with yellow hairs anteriorly (type), but some specimens 

 have black hairs entirely. Legs blackish, tlie fore til)iae usuallj- ob- 

 scurely reddish, on their basal third or half with some yellow hairs 

 occasionally reddish yellow on basal half, the middle and posterior 

 pair obscurely reddish or reddish 3'ellow, only black at their apices. 

 Wings tinged brown all along the veins, but in some specimens 

 only tinged very slightly. Length from 15 — 21 mm. The female 

 type 21 mm.
