The following specimens are in the British Museum 

 collection : — 



Type (female) and another from Lutete, Congo, Nov. 19, 

 190;5, presented by the Liverpool School of Tropical 

 Medicine, 1904. 267. 



A species with three series of grey spots on the abdomen 

 similar to those of Tabanus distinctus, Ricardo, to which it is 

 closely related, but the median spots in this species are not 

 connected and the legs are more wholly reddish, the fore 

 femora not being brownish ; it is also larger in size and 

 browner in colour. It is distinguished from Tabanus per^ 

 rasas, Wlk. (probably the same as the South-African form of 

 Tabanus bovinus), by the clear wings and the more distinct 

 triangular side spots with their bases resting on the posteriar 

 borders of the segments. It is distinguished from Tabanus 

 sdcficalis, Surcouf, from Font el Julon, N. of Sierra Leone, 

 by its larger size and more distinctly defined side spots. 



Length 20 mm.

 blackish only, red at the base. Forehead covered with 

 yellowish tomentum ; vertex not reddish, but with the same 

 tomentum ; the few hairs on the forehead seem chiefly 

 yellowish ; it is about six times as long as it is broad, 

 narrowing slightly anteriorly. Thorax brownish, with five 

 indistinct grey stripes, and the scutellum the same colour. 

 Abdomen brown ; the median spot on the second segment 

 with long apex, which, however, does not reach the posterior 

 border of the fir&t segment ; the second «pot on the third
