ERISTALODES. 91 



Six specimens from Nairobi, 3. v. 1911; one from British East 

 Africa, Kenyamkago {Dr. J. Pugh], and another from Marsabit 

 (JR. J. Stordy} ; a couple from Durban (F. Muir) ; a male 

 specimen from Stellenbosch, Cape Colony, xi. 1904 ( G. A. .. 



Marshall ). 



92. Eristalodes fuscicornis, KarscJi (1887). 



Characterised by having only three broad bands on the eyes and 

 the face almost entirely black, the lateral black stripes being 

 therefore indistinct. 



Karsch has described the male alone from Pungo-Andongo. In 

 the collection there is a single female specimen, which agrees well 

 enough in its general characters. It measures 14 mm. in length; 

 the frons is grev pollinose and dark-haired ; the vertex and a broad 

 band just above the antenna? are black ; there is also a broad dull 

 black band on the middle of the frons. Abdomen entirely black, 

 the first segment whitish cinereous ; the second with an indistinct 

 trace of the yellow band ; third and fourth entirely black, without 

 white bands. 



A single female specimen from British East Africa, Mt. Kenia, 

 W. side, 6,500 ft., 20. ii. 1911 (S. A. Neave).

 with short whitish hairs on the sides ; the grey pollen is distinct 

 on the sides, on the under border, and on two small lines on the 

 sides of the tubercle, the two stripes being also very broad, rect- 

 angular, and almost twice as broad as the middle stripe ; peristoma 

 shining, not produced; antenna? placed on a slightly prominent 

 tubercle, entirely brownish black, the elongate third joint having
