the front femora ; front tibiae not dilated but slightly carved as in the 

 typical Tabanus, short pubescence on the whitish portion (which is 

 slightly brownish on the underside) white and on the blackish portion 

 black, the black pubescence more or less scattered on the former one ; 

 two posterior pairs of the tibiae slightly brownish on the underside of 

 the paler portion, covered with short white pubescence which becomes 

 suddenly black on the apical blackish part and which is intermixed 

 with very few inconspicuous black hairs near the blackish part, and 

 the hind femora bearing a long conspicuous whitish outer-dorsal fringe 

 with some black hairs intermixed and a less long and less conspicuous 

 inner-dorsal fringe of numerous whitish hairs intermixed with some black 

 ones which are rather more abundant than in the outer fringe ; the 

 spurs of the middle tibiae unequal, rather small and brownish with the 

 base reddish yellow ; tarsi dull black, of which the posterior two pairs 

 have the reddish soles ; pulvilli yellowish brown, and the claws reddish 

 brown with the apical half black. 



Abdomen moderately, flat, broader than the thorax but the apical 

 part moderately narrowed, and a little longer than the head and thorax 

 (including the scutellum) together. Dorsum black, with a continuous 

 row of the large well-defined ashy grey tomentose triangles from the 

 first segment to the sixth segment, and on each of the basal two 

 or three segments there is one pair of similar but less ashy grey oblique 

 lateral triangles which are hardly reaching the anterior margin of the 

 segment but on the second segment sometimes broadly connected with 

 the precedings ; the hind margin of each segment more or less dusted 

 with grey especially on the second to third or fourth segments conspi- 

 cuous, these greyish bands gradually narrowed towards the apex ; the 

 sides of the segments all covered with ashy grey (less denser than in 

 the middle triangles) tomentum, especially on the first segment so 

 conspicuous as there are the large roundish grey side-spots ; pubescence 

 very short, dense, black, but on all the grey parts pale yellowish white.
