NORTH-EASTERN RHODESIA AND THE CONGO FREE STATE. 2^3 



State. AVhile agreeing with the type in all essential respects, these speci- 

 mens, as is not surprising, show certain slight divergences from the typical 

 form. Thus, in many individuals the dorsum of the second abdominal 

 seoment shows a tendency to become more or less clove-brown, the (larker 

 colour spreading from the anterior margin towards the centre. Again, the 

 hair on the posterior angles of the first abdominal segment is paler than in 

 Nyasaland specimens, the costal cells are generally darker brown and present 

 a greater contrast with the rest of the wing in colour, and the hair on 

 the outer side of the hind tibiae, instead of being wholly black, is on the 

 proximal half mixed with, or more or less replaced by, whitish or yellowish 

 hair. 



The localities (all of which are in or near Katanga) and dates of capture 

 of Mr. Neave^s specimens are as follows : — Mid-Lufira Valley, 3000 ft.. May,. 

 1907 ; Mfungwe to Kayumba, Lower Lufira River, 2000 to 3000 ft.. May 

 to June, 1907 ; and Bunkeya to Kambove, 3500 ft., September, ] 907.

Of this species, the type of which was taken in North Nyasa, Nyasaland 

 Protectorate, by Dr. J. B. Davey, " biting cattle," Mr. Neave obtained a 

 single female in the Luangwa Valley, 12-20 miles west of Petauke, 1700 ft., 

 on April 8, 1905.
