 more or less deep yellow soles, and with brownish pulvilli:

 (including the scutellum) conspicuously broader than the thorax, slightly 

 tapering towards the apex though it is somewhat parailel-sided, reddish 

 yellow with dark brown tip ; dorsum slightly brownish with a narrow 

 yellowish median stripe from the basal segment to the sixth segment, 

 and each segment with the much narrower similar coloured hind 

 margin, covered with an abundant short depressed black pubescence 

 but on the yellow median stripe and on the hind and lateral 

 margins of each segment there arc conspicuous golden yeliow hairs, 

 which become somewhat longer and erect at the sides ; ventre dusted 

 with grey, and with golden yellow pubescence, on the seventh segment 

 there are numerous long and erect black bristly hairs which do not

Described from a single female, in fairly good condition, taken 

 by the author at Arisan (July, 1914), Formosa. 



Somewhat allied to T. borniensis, Ricavdo, but apparently differs 

 from that by a broad frontal stripe which has two separated calli. 



When the author was resting upon some timber fallen on the 

 road in a wood, this handsome small Tabanus pierced his bare arm, 

 at about sunset. Its puncture was not very severe but its effect continued 

 for fully five days.

 from New Guinea, in appearance, but distinguished from that by two 

 separated shining blackish frontal calli and by all the tarsi black.
