at least as far north as Angola. The species is also found in the 

 French Sudan, in the vicinity of Lake Chad, where, according to 

 Dr. Kerandel, it feeds on hippopotami as well as cattle, and is known 

 to the natives as Kendogo, or Ter al Diamouss.* In West Africa, 

 somewhere to the north of Angola, and at any rate in Nigeria, 

 T. africamis would appear to be replaced by T. latipes, which ap- 

 parently is distributed across the continent from west to east, or at 

 least to Senaar, on the Blue Nile, so that it may eventually be found 

 that the two species occur together in Kordofan, or the Bahr-El- 

 Ghazal. The localities, etc., of the specimens of T. africanus at 

 present in the National Collection are as follows.
