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 
elis^ Streck. (which seemed to be very close to, if not identical witlt, C. 
hecla of Europe), Argy^inis alberta^ W. H. Edw., and Chionobas 
subhyalina^ 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 N^ew 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 Forjiculidce^ with asymmetrical 
forceps, from the summit of Mount Wellington ; two mimetic species of 
CEdeineridce^ belonging to the genus Fseudolycus, Guer., and the corre- 
sponding LycidcB^ which were found with them ; also specimens of both 
sexes of Lampriina rutilans^ Er. Mr. N. M. Richardson exhibited a 
specimen of Zygcena filipendulce 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 siibtillella^ a species new 
to Britain, taken last August in the Isle of Portland : also specimens of 
Nepticida auromarginella^ 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 Tezniocainpa mstabilis, 
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 {Sima rufo-nigra), from Bengal, together 
with specimens of a small sand wasp {Rhmopsis ruficornis) and a spider 
(Salticus), 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
