of E. hyale in which the black scaling at the apex was extended inwards 
nearly to the discoidal cell. Mr. Bacot also among his specimens had 
some E. electro, from South Africa. 
Discussion on British species of genus Eurymus.— The President 
started the discussion. He said he supposed all members agreed that 
the British species of this genus were as a rule migrants. Personally 
he considered that in such sheltered parts of the country as Torquay 
and the south coast of the Isle of Wight E. croceus (edusa) might 
breed regularly. E. hyale always appears to be a migrant, and never 
to breed on these shores. The Rev. Mr. Burrows had recently called 
his attention to the colour of the sexes in E. hyale. Do all the J s 
have the paler coloration and all the $ s the darker ? Mr. Prout 
then referred to the previous visitation of these Eurymus species in 
1892, and recollected that Mr. Battley, a former member of this Society, 
had traced the first specimens as having been seen at Dover, and 
later only in other parts of the country, pointing to a migration across 
the Channel at that point. Mr. Burrows in referring to the colour 
question of E. hyale quoted from Tutt’s British Butterflies, a passage 
where that author hints at a parallel case to the $ of E. croceus in the 
form helice. Subsequent examination of a number of specimens went 
to confirm this view. Mr. Mera said he had found that intermediates 
between E. croceus and var. helice were more frequent in Devonshire 
than elsewhere, and thought perhaps the extra warmth was in some 
Avay influential. Mr. Bacot mentioned that a specimen of the var. 
helice in Mr. Clark’s series was exactly like a § of E. electro, and 
he had some doubt as to whether the two species could satis¬ 
factorily be separated. Upon the discussion reverting as to 
whether either of E. croceus or E. hyale bred in these Islands, 
Mr. Burrows stated that he had taken E. croceus for three suc¬ 
cessive seasons. Mr. Pickett said he had never been to Folke¬ 
stone at the right time of year without meeting with this same 
species. Mr. James mentioned that E. hyale occurred at Broadstairs 
on September 25th, 1899. The President said that it was possible 
that eggs laid by stray 5 s last year had hatched, fed up and produced 
imagines in the present season. 
Nov. 20th, 1900.—Mr. Wilfred Dadd, of 3, Colina Villas, Wood 
Green, was elected a member of the Society. 
Epirrita dilutata.— Mr. Clark exhibited a long variable series of 
Epirrita dilutata from Polegate. 
Apamea ophiogramma near London, etc. —Mr. Riches, Apamea ophio- 
(jrarnma and A. secalis (dulyma ) from Hornsey Rise; the larvae of both 
species being found together feeding on cotton grass. Two fine Bisulcia 
ligustri were also shown. 
Proutias. —Mr. Prout, the Psychids Proutia hetulina and /’. 
eppinyella, with their cases, from Chingford. 
Spilosoma mendica.— Mr. Bacot, Spilosoma mendica $ s, one of 
which was very large and approaching the form rustica from Ireland. 
Xylina semibrunnea. —Mr. Kaye, a specimen of Xylina semibrunnea 
taken in his garden at Worcester Park on ivy bloom, on October 25th, 
1900. 
Xylena monoglypha, etc.— Dr. Sequeira, A plena monoglypha of the
