brown instead of bhick or clove-brown; upper distal angle of 

 first joint of antennffi is conspicuously tipped witli black, being 

 covered witb minute black hairs, and expanded portion of 

 third joint is sometimes dark brown or brownish, except 

 perhaps at hase ; on dorsum of thorax, especially on scutellum, 

 the black hair is often more in evidence, giving a darker 

 effect and rendering the covering of minute, appressed, bulf- 

 yellow hairs less noticeable; ground-colour of dorsum of 

 abdomen is usually darker, being dark brown or brownish 

 instead of tawny-ochraceous or ochraceous ; the series of 

 oblique, pale marks on dorsum of abdomen, outside adniedian 

 stripes, usually takes the form of clearly defined light grey 

 spots, which are often distinctly ovate in shape, in whicli 

 case they may not reach hind margins of segments on which 

 they are situated ; and, lastly, that ground-colour of all 

 femora, and not merely of those of front legs, is black. 



Abyssinia and the East Africa Protectoi ate : type of 

 variety, " caught in tent in daytime,^' and one other 

 specimen, " caught on camel in daytime,^^ from Hawash 

 Valley, Abyssinia, 30. viii. 1908 (Dr.R. E.lJrake-Brockman); 

 two additional specimens from Laga Hardin, Abyssinia, 

 " caught in tent," 3, 8. ix. 1908 (Dr. R. E. Drake-Brockman] ; 

 a fifth specimen from the East Africa Protectorate, between 

 Lake Kudoif and the boundary of Abyssinia, January- 

 February, 1910 (A''. C, Cuckbu7-n). Ey the courtesy of Baron 

 .7. M. Iv. Surcouf, the author has been enabled to examine 

 an additional example of this variety, from Goudar, Abyssinia, 

 10. ii. 1907 (//. Za/Ziom), now in the collection of the Museum 

 National d'llistoire Naturelle, Paris. 



The variety described above was formerly referred to by 

 the author {lac. cit. p. 293) as a " species.'^ The entire 

 absence of plastic differences, however, as well as the, in 

 some respects, intermediate character of the recently acquired 

 si)ecimen from the East Africa Protectorate (in which, 

 though all the femora are black, the hairy covering of the 

 dorsum of the thorax and the shape of the outer greyish 

 abdominal markings are as in the typical T. k'uu/i), seems, on 

 further consideration, scarcely to justify this view.
