249 Dr. A. G. Butler on Charaxes azota. 



what he now recognized as a true Charaxes. His type of the 

 latter, still in his collection, was received from Nyasaland, 

 and obtained by Mr. Thelwall. 



In 1892 a specimen of the true male of G. azota was 

 received from Delagoa Bay, through the Rev. Henri A. 

 Junod, and in 1894 Mr. Whyte brought home a collection 

 from Zomba in which was a male corresponding with 

 Mr. Hewitson's example, and clearly proving that the forms 

 from Delagoa Bay and Nyasa are as distinct as G. azota 

 itself from G. protoclea. They may then be distinguished as 

 follows : 



C. azota. C. nyasana.

 out defined spots from inner margin well-defined black spots at centre 

 to second median branch, whence of each division, but undivided

Delagoa Bay. Nyasaland (Zomba). 



G. azota was described shortly before Mr. Hewitson's 

 death, and it is possible that the female type may never have 

 been actually purchased from Mrs. Monteiro, who (in her 

 work on Delagoa Bay) gives an illustration of it ; at any 

 rate, it is not in his collection, and was not there when 

 Mr. Kirby catalogued it. The male from Nyasa, however, 

 is in the series of Gharaxes, though only labelled with its 

 locality, and corresponds tolerably closely with the specimen 

 brought home by Mr. Whyte, thus clearly proving the 

 Nyasa form to be constant in its characters.
