AnnuaL Exuisition oF tae SoutH London ENroMoLoGicaL AND 
Natura Hisrory Sociery.—Falling as it does on the very eve of the 
new collecting season, the date fixed for the next Annual Exhibition of this 
Society (May 5th and 6th) appears to be well chosen, and the affair pro- 
mises to be a great success. ‘he Committee, upon whom the arrangements 
devolve, desire to make this year’s exhibition as attractive and instructive 
as any previous one. Of course the success of the enterprise largely depends 
upon the members themselves, and there is no doubt each one of them has 
liberally responded to the Secretary’s appeal for assistance. 
SOCIETIES. 
Entomotoetcat Soctety or Lonpon.—April 138th, 1892.— Mr. Henry 
John Elwes, F.L.S., Vice-President, in the chair. Mr. Francis Jaffrey, 
M.R.C.S., of 8, Queen’s Ride, Barnes, S.W., was elected a Fellow of the 
Society. Mr. R. McLachlan exhibited specimens of Anomalopteryx chau- 
viniana, Stein, a Caddis-fly remarkable for the abbreviated wings of the 
male, the female having fully developed wings; he alluded to the Perlide 
as including species in which the males were frequently semi-apterous. 
Dr. Sharp enquired if Mr. McLachlan was aware of any order of insects, 
except the Neuroptera, in which the organs of flight were less developed 
in the male than in the female. Mr. C.G. Barrett and Mr. H. J. Elwes 
cited instances amongst the Bombycide in which the wings of the male 
were inferior in size and development to those of the female. Dr. Sharp 
exhibited specimens of both sexes of an apparently nondescript phasmid 
insect allied to Orobia, obtained by Mr. J.J. Lister in the Seychelles 
islands, together with Phyllium gelonus. He also exhibited specimens of 
both sexes of an Acridiid insect, of the group Proscopides, remarkable for 
its great general resemblance to the Phasmide, though without resem- 
blance, so far as is known, to any particular species. In reference to the 
Phyllium, Dr. Sharp called attention to the fact that the similarity of 
appearance of parts of their organisation to portions of the vegetable king- 
dom was accompanied by a similarity, amounting almost to identity, of 
minute structure. He said that it had been stated that the colouring-: 
matter is indistinguishable from chlorophyll, and that Mr. Lister had 
informed him that when in want of food a specimen of the Phyllium would 
eat portions of the foliaceous expansions of its fellows, although the 
Phasmide are phytophagous insects. The resemblance to vegetable pro- 
ducts reached its maximum of development in the egg; and Mons. 
Henneguy had observed that when sections of the external envelope of the 
egg of Phyllium are placed under the microscope no competent botanist 
would hesitate to pronounce them to belong to the vegetable kingdom. Dr. 
Sharp also stated that in some species of Phasmide it was easy to obtain 
the egg by extraction from a dried specimen. Mr. Barrett exhibited, for 
Major J. N. Still, a specimen of Notodonta bicolora, which had been 
captured in a wood near Exeter. Major Still had stated that the captor of 
the specimen was unaware of the great rarity of the species. Mr. Barrett 
also exhibited, for Mr. Sydney Webb, some remarkable varieties of 
Argynnis adippe and Cenonympha pamphilus; also two specimens of 
Apatura iris, and two of Limenitis sibylla in which the white bands were 
entirely absent. The Hon. Walter Rothschild exhibited, and contributed
