Rare dipteron. —Mr. Jennings, a specimen of tkeclipteron, Hyelemia 
praepollus, Wild., taken at Edmonton. The specimen was caught in 
August, 1896, but he had only recently been able to obtain the name 
of the insect from our most eminent authority, Mr. Verrall, who had 
examined it. 
Anthocaris belemia. —Dr. Chapman, a living specimen of A. 
belemia, and remarked on the somewhat unusual habit it had of resting, 
whereby the striped underside was shown so that the stripes assumed 
a vertical position. 
Hesperia comma.— Mr. Pickett, a series of H. comma taken on the 
Guildford downs. 
Death of member.— Mr. Bell read a letter from the son of Mr. W. 
Gates, a former member, in which it was announced that Mr. W. Gates 
had recently died at the age of 71. Upon this Mr. Tutt moved that 
the secretaries be asked to write for any manuscript notes that Mr. 
Gates might have left, for the benefit of the Society, and to convey to 
the son the great regret of the Society at the loss of one of its 
oldest members. Mr. Clark seconded and the motion was carried. 
Paper.— Mr. Kaye read a paper on “ The re-classification of the 
Lepidoptera ” (Printed in the transactions). 
Feb. 20th, 1900. —Magazine.— Mr. Jennings announced that he had 
received the Halifax Magazine for the library. 
Lepidoptera from Fusio.— Mr. Edwards exhibited three boxes of 
lepidoptera taken at Fusio, and Dr. Chapman also exhibited a large 
number of insects from the same locality. 
Triph^na janthina, etc. —Mr. Clark, a bred specimen of T. 
janthina that had been forced through the winter. Mr. Pickett exhibited 
a long series of Ematurga atomaria from several localities, showing 
light and dark forms. 
Paper.— Mr. Donisthorpe read a paper on the “ Myrmeeopkilous 
Coleoptera.” He divided it into three sections: (1) On the life- 
history, mimicry and relations to the hosts of myrmeeopkilous 
coleoptera. (2) On the best methods of collecting the British species. 
(3) A table classifying all the British species recorded, in the manner 
used by Wasmann for the mynnecopkila of Hollandisk Limburg. In 
speaking about mimicry and protective resemblance, Mr. Donisthorpe 
mentioned that, in certain cases, the resemblance was complete except 
for colour. This was pointed out to have less significance, than at first 
sight appeared, as it was known that in certain species of ants the sight was 
very feeble. Many of the myrmeeopkilous coleoptera acted as scavengers, 
such were some of the Staplujlinidae and Histeridae, which were to be 
found in the channels with Formica rufa. Protection was said to be 
afforded in a variety of ways. Amongst the Coccinellidae, Coccinella 
distincta was mimicked by Clijthra 4 -punctata. Others are able to 
protect themselves by curling themselves up, while Atemeles emarginatus 
imitates the movements of ants. All true guests were said to have 
tufts of golden hair situated on the abdomen generally. It was known 
that certain species in the genus Atemeles even changed their host at 
different times. In his remarks on the method of working for these 
myrmeeopkilous coleoptera, Mr. Donisthorpe had found that the spring 
and autumn were the best periods of the year, but it frequently 
happened that some days were favourable with no apparent reason.
