forehead anteriorly likewise whitish, but with a bright brassy 

 3^el]ow glimmer ; the shining black callus situated rather far from 

 the antennae, oblong, filling up the entire width of forehead, its 

 posterior border with two incisions so that points appear at each 

 side, but from the middle a shining black line proceeds towards the 

 vertex, which is at first wider and from behind to the middle deeply 

 incised fork-like ; in the place where usually the ocelli are situated 

 appear two shining black raised little lines near each other ; the 

 remaining surface of the forehead is grey tomentose, as is the rather 

 distinctly concave hind part of head ; proboscis black and short, 

 the labella long. Palpi black-brown, with paler tomentum, broad 

 at the base then gradually ending in a point, curved, a little shorter 

 than the proboscis. Antennae black, the first projecting above; 

 the second very short with a thorny point, the third on the upper 

 side with a shallow incision, the angle onl^' slightly projecting. 

 Eyes naked. Legs black, the tibiae by reason of the paler thick 

 tomentum at the base, appearing whitish, the fore tarsi unusualh' 

 broad and short. Wings tinged deep smoky brown, the centres of 

 cells rather paler, fore border darker, the first posterior cell widely 

 open, no appendix. Length 7 lines. Four females from Nicobar 

 Islands, one from Nankauri, the others from Sambelong. The 

 species could only be compared with Tahanus brunneus, Macq., but 

 there is no trace of black spots on the abdomen, neither of median 

 spots, and the sides are not whitish yellow, Tabanus brunneus 

 is also larger— 8 lines. vSchiner, Reise Novara Dipt., p. 81.

In these specimens the livings are clear, veins brown. The 

 forehead is about eight times as long as it is broad, and a third 

 narrower anteriorly. The frontal callus large, a little protuberant, 

 reaching the eyes, with a lineal extension. Length i6-i6| mm. 

 The comparison with Tabanus brunneus appears to me mislead- 

 ing, but no doubt Schiner had not had the advantage of seeing the 

 type.
