it by breeding both from the larva. Mr. Fryer's remarks on other species, 

 especially Terias, were passed in review, and Mr. Godman concluded by 

 calling attention to Mr. W. H. Edwards's beautiful plates representing the 

 winter and summer broods in the genus Phyciodes, which is allied to 

 MelitcBa, in Part VII. of the second series of his ' Butterflies of North 

 America'; he also stated that Mr. Edwards was working at the same 

 subject in other groups. 



Mr. R. Meldola said that Mr. Pr^^er's remarks were of extreme interest 

 to him, but only wished that the author had submitted wings of the different 

 broods of his bred species that they might be figured in illustration of his 

 remarks. Dr. Weisraann had already remarked that many species were 

 not seasonably dimorphic in Northern Europe, but were distinctly so 

 further south ; this appeared also to hold in Japan. His researches 

 tended to prove that the changes were more or less affected with the 

 duration of the pupal state rather than the larval, and that those species 

 having well-marked dimorphic or temperature broods mostly hybernated 

 as pupte. 



Mr. E. A. Fitch did not think these temperature forms were always 

 constant, but that they varied according to localities and seasons :' he 

 especially referred to the very distinct third brood of Colias Edusa which 

 was produced in Britain in 1877. 



Mr W. L. Distant made some remarks on Mr. Pryer's notes, and 

 expressed the belief that many of our so-called species were but seasonal 

 or dimorphic forms of others, and hoped that those naturalists who had the 

 opportunity of breeding various species would turn their attention to the 

 subject. Wallace had already expressed his opinion that Papilio Pammon 

 and P. Memnon possessed both dimorphic and trimorphic forms of the 

 female ; still this was awaiting actual proof, and he hoped that Mr. W. B. 

 Pryer would do for these species what his brother had done for P. xuthus 

 and P. xuthulus. 



Mr. P. C. Wormald joined in the discussion, and said with reference to 

 Mr. Distant's remarks about his relative Mr. W. B. Pryer, he was now 

 Governor of the Sandakan district of North Borneo, and could give but 

 very little time to his favourite study. 



Mr. F. P. Pascoe, after congratulating the Society on the two important 

 papers just read, remarked that some years ago Sir Emerson Tennant 

 published, in liis work on Ceylon, a list of the Coleoptera, drawn up 

 principally by Mr. Walker, from which it appeared that rather more than 

 half the genera were European ^184 out of 358), thereby shewing that, so 

 far as the Coleopterous fauna was concerned, Ceylon, like India, formed 

 part of a transitional zone between the Palsearctic and Indo-Malayan regions. 

 A list with Mr. Lewis's discoveries and a more modern appreciation of 

 genera will be very valuable,
