 and hind tibiae and tarsi dark brown, middle tibiae each with a pair of cream- 

 coloured or cream-buff bands of approximately equal depth, hind tibiae each with 

 a somewhat deeper band of same colour a little beyond base, and a narrower, less 

 brightly coloured, and more or less incomplete cream-buff band on distal third ; 

 pale bands on middle and hind tibiae clothed with yellowish-white or yellowish

German East Africa : type and one para-type from the Ruaha Valley, 

 North Uhehe District, 19.xii.1910 (S. A. Neave). Additional para-types as 

 follows (all collected by Mr. S. A. Neave) : — one from North Uhehe District, 

 15. xii. 1910 ; one from the foot of Kifulufulu Mountain, Iringa-Kilossa Road, 

 Usangu District, 3,000 ft., 16 or 17. xii. 1910 ; six from South Usagara District, 

 22-24. xii. 1910. The whole of the foregoing specimens, with the exception o£ 

 two of the para-types from South Usagara, which are retained by the Com- 

 mittee, have been presented to the British Museum (Natural History) by the 

 Entomological Research Committee. 



Haematopota crudelis is closely allied to H, cruenta, Austen (of which the 

 type and only specimen at present known is from the Katanga District of the 

 Congo Free State), to which it presents a somewhat deceptive resemblance in 

 general appearance ; the new species can, however, be distinguished from 

 H. cruenta by the first joint of its antennae being considerably longer, by the 

 greater development of the grey markings on the hind border of the main 

 portion of the dorsum of the thorax, by the absence of a deep clove-brown 

 edging to the scutellum, and by the knobs of its halteres being entirely white or 

 cream-coloured, instead of seal-brown at the base above and below.
