Plate VI., fig. 43. 



As already stated in the notes on Tabanus africanus, Gray, T. 

 latipes, Macq., would appear to be the West African representative 

 of that species, although, since T. latipes has been met with in Senaar, 

 it evidently extends across the continent, so that the areas of the 

 two species probably overlap in Kordofan or the Bahr-El-Ghazal. 

 On comparing figs. 42 and 43, Plate VI., it will be seen that the 

 present species agrees with T. africanus in the coloration and mark- 

 ings of the body, as also in the general arrangement of the wing- 

 markings, but that it is distinguished by the brown on the costal 

 border of the wing not being continued beyond the stigma (there 

 being no inf uscation at the tips of the second and of the upper branch 

 of the tliird vein), and by the brown band across the middle of the 

 wing not reaching the hind margin. According to Mr. G. C. 

 Dudgeon, the eyes in hfe are " deep blue." 



Tabanus latipes, which was originally described from Senegal, 

 is also found in southern Mauritania, to the north of the Senegal 

 River, in the Brakna and Tagant countries.* With the exception 

 of two specimens from Senaar, the fourteen females by which the 

 species is at present represented in the National Collection are all 

 from Northern Nigeria. The following are the details as to localities, 

 dates, and collectors. —
