Baker proposes to deal with the question of E. dipora^ so will 

 not enlarge on this very interesting species. But there is one 

 point to which I wish to call special attention, and that is that 

 G. sikkima is a race of C, aryiolus, C. jynteana a race of C. 

 limbatus, and the Everes diporides is a race of E. argiades. 

 These three are blues with very little if any black margins to 

 the wings. It is very possible that further research may show 

 that the other species have forms without dark borders ; so 

 far I have not met with such forms. All these species, 

 C. sikkima, G. jynteana, B. chennellii, N. hinghami, E. dipora, 

 and E. diporid^'S, occur, presumably more or less together, 

 in the Khasya district, and probably in other areas, though 

 I have not records of all the species from any other one 

 district. 



" I differentiate the species, doubtfully by their wing char- 

 acters, but I might almost say infallibly by the genitalia, 

 which happen in these forms to be in every case remarkably 

 different from those of any other of the group. 



" As to which is the model and what may be the object of 

 this mimetic group, I will hardly ventui-e to say anything. 

 But it is clear that the blue argiolus joins the group as 

 sikkima, the blue lifnbatus (which seems to be identical with 

 placida specifically) as jynteana, and the blue argiades as 

 diporides. E. dijyora is closely allied to argiades and was 

 therefore originally blue. Tiiis would leave chennellii or hing- 

 hami as probable models. 



" C. argiolus, whatever it may be elsewhere, is in India 

 clearly a species looking for protection in many directions. 

 It is curious that though something like a dozen forms 

 of argiolus, differing in no great degree from the ordinary 

 form, have received specific names as distinct species, 

 only two forms of very different facies have been recognised 

 by being named as distinct species, viz. sikkima, already dealt 

 with, and the still more remarkable form victoria, Sw. In 

 addition to these are two forms of which I exhibit specimens, 

 one of which resembles jmspa and the other albocseruleus (or 

 marginata). This latter form was found at South Kensington 

 pia,^ed with alhocserideus. 



" C. victoria, Sw., is a form of which I know little, and have
