the S.W., and everywhere eastward from the N.E. shores of 

 the Lake to the coast, the dorijijyus form was more abundant 

 than the type form, and that in all his experience he had never 

 received from any of these localities such a group as that now 

 exhibited. 



A Mimetic Group of Indian Celastrinids (Cyaniris) and 

 EvBRiDS. — Dr. T. A. Chapman exhibited specimens of several 

 species of Indian Lycsenids, forming a group curiously alike, 

 especially on the upper surface ; so much so that, with regard 

 to the first four of them, none of our great authorities on 

 Indian Butterflies express any clear view of them. He said : — 



" Moore named C. sikkima, but afterwards mixed specimens 

 of it with his series of jynteana, while de Niceville and Bing- 

 ham sunk it, as possibly a seasonal variety of jynteana, but 

 actually indistinguishable from that species. C. sikkima 

 is, however, a form of G. argiolus, and very distinct from 

 C. jynteana.* B. chennellii was regarded by de Niceville as a 

 Celastrina {Cyaniris)^ it is however not a Celastrinid, but an 

 Everid. I feel sure that de Niceville would not have made 

 such a mistake on the simple merits of B. chennellii, and there- 

 fore believe that though his type specimen of B. chennellii 

 belongs to the species known under that name, he really formed 

 his first (and correct) opinion from iV. hinghami, afterwards 

 making his description from a B. chennellii. 



" Col. Bingham's specimen (or at least the one he showed 



me as certainly correctly named) of B. cheniielUi proved to be 



a specimen of N. hinghami. I presume that if de Niceville's 



series of cJiennellii is examined, it will be found to include 



examples of hinghami. Since noting the latter species in Proc. 



Zool. Soc, 1908, p. 676, I have found a third specimen in 



Moore's series of C. jynteana, so that this series contained 



specimens of jynteana, sikkima and hinghami. This specimen 



is the one here exhibited. I have to apologise for the condition 



of this and other examples shown, as I have only brought 



specimens belonging to myself, but I have worked out the 



questions involved in larger numbers of better specimens in 



the British Museum, and elsewhere. I exhibit also a specimen
