the remaining segments blackish and reddish brown, with thick 

 yellow-haired segmentations on third, fourth and fifth segment , 

 less distinct on the second, the fifth is almost covered with ^^ellow

 cence ; under side similar, the segmentations lighter coloured with no 

 pubescence. Legs yellow, fore pair and all tarsi reddish brown. 

 JVings slightly tinged yellow on the fore border and apex ; veins 

 and stigma yellow. 



The specimen in Brit. Mus. coll. has a few black hairs on the 

 first joints of antennae. Beard scanty, pale yellow. Forehead 

 one-third narrower anteriorh-, brown, covered with grey tomentum, 

 the lineal extension of callus reaches more than half wa}- to the 

 vertex, which is reddish brown. vSides of thorax with yellowish 

 white hairs. Legs yellow, the fore femora reddish brown, the poste- 

 rior ones paler. 



x-Vnother specimen from Sarawak has a label in Walker's hand- 

 writing ' ' hybridus ' ' but I believe it to be a specimen of this species ; 

 the fore femora and tibiae are whollv vellow.

 Type 9 from Ce^don ; and 3 other females from Pundaluoya, 

 Ceylon (Green) ; and another from Peradeni3^a, Ceylon (Green) ; 

 others from Kajoe-Tanan, Sumatra, June 1907 (Dr. Hagen). 



This species described by Bigot from a single specimen is a 

 reddish brown medium-sized species with clear wings, blackish, 

 legs and tibiae 3'ellowish, with a very narrow forehead and long 

 narrow frontal callus. Abdomen with no spots except an indistinct 

 black median mark on the second segment, the segmentations 

 narrowly paler. Length of type 15 mm., others from 14-15 mm. 



This species might possibly be confounded with small speci- 

 mens of Tabanus fumifer, Wlk., but may be distinguished by the 

 absence of any median pale spots on abdomen, by the lighter reddish 

 5^ellow tibiae and by the paler segmentations of abdomen with white 

 or yellow hairs. 



Face covered with grey tomentum, on cheeks and near antennae 

 with 3'ellowish brown tomentum, pubescence white. Beard white. 

 A few brown hairs are present on the upper Dart of face and at sides 

 of antennae. Palpi stout, ending in a fairly long point, yellow with 

 black pubescence, a few white hairs visible at the base. An- 

 tennae dull red, duskier at the apex, the first two joints and apex 

 of tooth which is distinct, with black hairs. Subcallus and forehead 

 yellowish brown with grey tomentum. Forehead very narrow, about 

 nine times as long as it is broad, a third narrower anteriorly, the 

 frontal callus ver}' narrow, long, l)r()wn, not reaching the eyes, 

 with a linear extension, the pubescence on forehead black. Thorax 

 blackish brown, no stri])es visible, co\'ered with grey tomentum
