4. On Collections of Lepidoptera from British Central Africa 

 and Lake Tanganyika. By Arthur G. Butler, Ph.D., 

 F.L.S., F.Z.S., &c. 



[Received March 12, 1895.] 

 (Plates XV. & XVI.) 



In 1894 we received, through Mr. A. Wh)i:e, P.Z.S., a small 

 collection o£ Lepidoptera made at Zomba by Mr. J. McClounie, 

 especially remarkable for the number of specimens of tbe genus 

 Charaxes which it contained. Among these were specimens of the 

 female of C ivhytei (the male of which I had described and figured 

 in the Society's Proceedings for 1893), of two pre^dously unnamed 

 forms, possibly distinct species, and of two undoubtedly new 

 species, also examples of C. nyasana confounded by the late 

 Mr. Hewitson with his C. azota. 



A second series has been selected from a large consignment of 

 Lepidoptera collected at Pwambo, Lake Tanganyika, by Mr. Alex- 

 ander (5arson. This is especially interesting, not only as including 

 examples of rare species preA'iously only received from Zomba
