C. T. BBSTGHAM— HYiMENOPTERA. • I83 



Genus Megachile Latr. 



19. Megachile kobertiana Cam. Tr. S. Afric. Phil. Soc. xv. p. 248 (1905). 

 One female from Mokia, S.E. Ruwenzori, 3500 ft. May. 



The type, now in the British Museum, is from Pearston, Grahamstown. 



20. Megachile laevata Gerst. Monatsber. Akad. Berlin, 1857, p. 461 ( c? ); id. Peters, 

 Reise n. Mozamb., Zool. v. 1862, p. 456 ( <S ), pi. xxix. fig. 11. 



One male, Mubuku Valley, E. Huwenzori, 5000-7000 ft. 31st January. 



One female, Ruweuzori, 7000-8000 ft. (G. F. Scott Elliot). 



Dalla Torre and other authors have sunk Gerstaecker's M. larvata as a synonym of 

 M. rufiventris Guerin, from India, but the clypeus in the $ of the Indian species is 

 totally diiferent from that of the African form. Guerin's description is very insufficient, 

 and his figure corresponds neither with the description nor with any Indian form of 

 Megachile known to me. I may add that, in vol. i. of the Hymenoptera. Fauna 

 British India series, I joined M. rufiventris Guerin with M. mystacea Fabr., an 

 Australian species, but further careful comparison has convinced me that the two 

 forms are distinct. 



Genus Apis Linn. 



21. Apis mellifica Linn, race fasciata Latr. Ann. Mus. hist. nat. v. p. 171 (1804). 

 Two females from Mubuku Valley, E. Ruwenzori, 6000-13,000 ft. January. 



The death of Colonel Bingham occurred before he had been able to complete his 

 report on the Hymenoptera collected by the Ruwenzori Expedition. The foregoing 

 has been drawn up from manuscript which he left.
