who illustrated his remarks with projections on the screen— by oxy- 
hydrogen light—of instantaneous photographs taken by him, to which

ENnromonoeicaL Society or Lonpon. 
July 3, 1889.—The Right Hon. Lord Watstxauam, M.A., F.R.S., 
President, in the chair. ° 
The Rey. W. A. Hamilton (Calcutta), and Mr. H. W. Vivian (Glenafon, 
Taiback, South Wales), were elected Fellows of the Society. 
A letter was read from Mr. E. J. Atkinson, Chairman of the Trustees 
of the Indian Museum, Calcutta, in which assistance was asked from 
British entomologists in working out various orders of Indian insects. 
The following motion, which had previously been unanimously passed 
at the meeting of the Council, was read to the Society :—‘ That papers 
containing descriptions of isolated species widely remote in classification 
or distribution, are, as a rule, undesirable for publication, as tending to 
create unnecessary difficulties for faunistic or monographic workers.” 
Mr. M‘Lachlan, Mr. Jacoby, Mr. Elwes, Dr. Sharp and others took part in 
the discussion which followed. 
Mr. J. W. Slater exhibited a doubtful specimen of Arctia mendica, L., 
which appeared as if it might prove to be a hybrid between that species 
and A. lubricipeda, L. 
Mr. M‘Lachlan, on behalf of Prof. Klapalek, of Prague, who was present 
as a visitor, exhibited preparations representing the life-history of Agrio- 
typus armatus, Walk., showing the curious appendages of the case. Prof. 
Klapalek, in answer to questions, described the transformations in detail. 
A discussion followed, in which Mr. M‘Lachlan and Lord Walsingham 
took part. 
Mr. H. J. Elwes exhibited a specimen of an undescribed Chrysophanus, 
taken in the Shan States, Upper Burmah, by Dr. Manders, which was very 
remarkable on account of the low elevation and latitude at which it was 
found; its only very near ally appeared to be Polyommatus Li, Oberthur, 
from Western Szechuen, but there was no species of the genus known in 
the Eastern Himalayas or anywhere in the Eastern tropics. 
Mr. G. T. Porritt exhibited a remarkable series of Arctia mendica, L., 
“bred from a small batch of eggs found on the same ground at Grimescar, 
Huddersfield, as the batch from which the series he had previously exhibited 
before the Society was bred. This year he had bred forty-five specimens, 
none of which were of the ordinary form of the species: as in the former 
case, the eggs were found perfectly wild, and the result this year was even 
more surprising than before.
