EENEST E. AUSTEN — DIPTEEA. 93 



Hab. Ruwenzori and Entebbe, Uganda Protectorate ; and Ashanti and Sierra 

 Leone, W. Africa ; type of 6 from Mubuku Valley, E. Ruwenzori, 6000-13,000 ft., 

 17th Jan. ; type of ? from Sierra Leone (ex Bigot Collection, presented by 

 Mr. G. H. Verrall) ; the other specimens in the Museum collection include a S , 

 taken between Salt Lake and Wawamba Country, Ruwenzori district {G. F. 

 Scott Elliot) ; another $ , from Entebbe, Uganda, May, " caught in laboratory " 

 (Captain E. D. W. Greig, I.M.S.); 3 c? d and 1 $ from Obuasi, Ashanti, January, 

 June, August, and September {Dr. W. M. Graham) ; and a 6 and $ from Sierra 

 Leone (taken respectively by Surgeon-Captain Clements and J. Fooccroft). 



Megaspis bulligera may at once be distinguished by the coloration of the body and 

 wings from Megaspis bullata (Eristalis bullatus) Lw. (Ofvers. af K. Vet.-Akad. 

 Forhandl. 1857, 381 ; and ' Die Dipteren-Fauna Siidafrika's,' 1860, [391] 319), which, 

 also has shining tubercles on the abdomen, and the type of which was taken in Caffraria : 

 in M. bullata the body and the front portion of the proximal half of the wing are deep 

 black. In the 6 of M. bulligera, taken by Surgeon-Captain Clements in Sierra Leone, 

 the light area on the second abdominal segment is of a wood-brown instead of a dull 

 cinnamon-rufous colour, while, with the exception of the raised tubercles, the parts of 

 the abdomen that are normally black are merely mummy-brown. The specimen 

 selected as the type of the $ , which, as stated above, is from the collection of the late 

 M. Bigot, bears the following label in Bigot's handwriting: — ''Eristalis trichopus, ? . 

 K sp. inedicf. Quincy, Novembre 1891. M. Bigot. — Sierra Leone." No species, 

 however, appears to have ever been described by Bigot under the name Eristalis 

 trichopus, and the specimen does not, as at first seemed probable, agree with the 

 description oi Simoides trichopus Bigot (Ann. Soc. Ent. Fr. Ix. 1891, 373), the type of 

 which, moreover, would appear to be from Assiui.
