ABSTRACT OF PROCEEDINGS. 



JANUARY \oth, 1889. 



T. R. BiLLUPS, Esq., F.E.S., President, in the Chair. 



Mr. Jenner Weir exhibited specimens of LhnncBa truncatula, 

 Miill., collected by Mr. Cockerell in Colorado, which appeared 

 to be in all respects identical with the ordinary English form 

 of that species. 



Mr. Jenner Weir also exhibited a ? specimen of Anosia 

 plexippus, L., which he had received from Mr. Cockerell, 

 Custer County, Colorado. Although in this specimen the inner 

 edge of the wing was quite as black as in those received by 

 him from Canada and Hudson's Bay, it yet differed in the 

 colour of the spots on the fore wings being all white, whereas 

 in the northern specimens the four large central spots were of 

 a fulvous brown, little inferior in richness to that of the disk 

 of the wing. 



He exhibited at the same time the water-colour drawing 

 which Miss Crallan had made from the specimen taken at Lind- 

 field in 1876, from which it would appear that the example then 

 captured resembled the more Northern form of the species. 



Mr. Jenner Weir also exhibited the following, received 

 from Mr. Cockerell : — 



MelitcBa minuta, Edwards, a small species allied to M. athalia 

 Rott., Parnassiiis sinintheus, closely allied to, if not a geo- 

 graphical race of, P. delius, Esp., of the Alps. 



Euchloe ausonides, a species similarly allied to the European 

 E. ausonia, Hb. 



Pieris olevacea, $ and ? , Boisd. This species he had 

 contended was not identical with our well-known P. napi, L., 

 and he was glad to read a communication he had received 

 from Mr. Scudder on this point: — "I have to-day, for the 

 first time, been able to make the comparisons I wished 

 from the specimens you sent me, and I can report that the
