Entomological Society of London. — April i, 1891. — Capt. H. 

 J. Elwes showed a small but very interesting collection of butterflies 

 "from Laggan Alberta, N.W. territory of Canada, taken by Mr. Bean at 

 high elevations in the Rocky Mountains. Amongst them were Colias 

 ells, Streck. (which seemed to be very close to, if not identical with, C. 

 hccla of Europe), Argynnis alberta, W. H. Edw., and Chionobas 

 subhyalitia, W. H. Edw. The resemblance between the butterflies of 

 this locality and those found on the Fells of Lapland was very striking, 

 some of the species being identical, and others very closely allied. 

 Capt. Elwes said that it was another proof, if one were wanted, of the 

 uniformity of the butterflies found throughout the boreal region in the 

 Old and New Worlds. Mr. G. C. Champion exhibited several insects 

 recently received from Mr. J. J. Walker, from Hobart, Tasmania. The 

 collection included a curious species of Forficulidct, with asymmetrical 

 forceps, from the summit of Mount Wellington ; two mimetic species of 

 (Edemeridce, belonging to the genus Fseudolycus, Guer., and the corre- 

 sponding Lycidce, which were found with them ; also specimens of both 

 sexes of Lamprima rutilans, Er. Mr. N. M. Richardson exhibited a 

 specimen oi Zygcena filipendjilce with five wings; a second specimen of 

 the same species with the middle legs on the right side much dwarfed ; 

 four specimens of Gelechia ocellatella, including a pink variety, bred 

 from Beta maritima ; four specimens of Tinea subtillella, a species new 

 to Britain, taken last August in the Isle of Portland : also specimens of 

 Nepticula auroinargineUa, a species new to Britain, bred from larvae 

 taken near Weymouth on bramble. Dr. Sharp and Mr. M'Lachlan 

 commented on the structural peculiarities of the two specimens of 

 Zygcena. Mr. C. Fenn exhibited a series of TcEiiiocampa instabilis, 

 which had been bred out of doors during the recent severe weather. 

 They were all bred from ova laid by the same female, and many of 

 them were of an abnormally pale colour. Mr. Fenn said that, accord- 

 ing to Mr. Merrifield's theory, these pale specimens, in consequence of 

 the temperature to which they had been subjected in the pupal state, 

 ought to have been very dark. Mr. Jenner Weir, referring to the 

 pale specimens, said he had never before seen any of so light a colour. 

 Mr. W. Dannatt exhibited a butterfly belonging to the genus Crenis, 

 recently received from the Lower Congo. He said he believed the 

 species was undescribed. Mr. G. A. J. Rothney sent for exhibition 

 several specimens of an ant {Si ma rufo-/iigra), from Bengal, together 

 with specimens of a small sand wasp [Rhtiiopsis ritficornis) and a spider 

 {Saiiicus), both of which closely mimicked the ant. It was stated that 

 all the specimens exhibited had lately been received from Mr. R. C. 

 Wroughton, Conservator of Forests, Poona. Mr. Rothney also com- 

 municated a short paper on the subject of these ants and the mimicking
