The types of the new species described in the following pages are in the British 
Museum (Natural History). 
Tabanus necopinus, sp. n. (fig. 1). 
©.—Length (3 specimens), 14°75 to 16°5 mm. ; width of head 5:4 to 5°8 mm. ; 
width of front at vertex just under 1 mm.; length of wing 13 to 144 mm. 
Fig. 1.—Tabanus necopinus, Austen, 2. x 3. 
Closely allied to Tabanus africanus, Gray, and T. latipes, Macq., and—eacepi 
for certain small differences in the wing-markings and the usually greater extent of 
the black lateral blotches on the abdomen, at any rate on the third and fourth seg- 
ments—agreeing absolutely with these species in the coloration, appearance, and 
markings of the dorsal surface, as also in the uniformly black coloration of the legs, 
and in the shape of the front tibiae; distinguishable from both species mentioned by 
the ventral surface of the abdomen (except its basal angles and the hind margins o/ 
the second to the sixth segments inclusive) being entirely black. 
Head and palpi as in T. africanus ; antennae as in the same species and in 
T. latipes, except that third joint is less elongate and less attenuated. Thorax 
as in the two species mentioned. Abdomen: dorsum as in the same two species, 
with the difference as regards the black lateral blotches already pointed out in 
the diagnosis printed in italies above ; renter, except as stated in diagnosis and
