Mr. R. McLachlan exhibited specimens of Anomalopteryx Chauviniana, Stein, 

 a caddis-flj remarkable for the abbreviated wings of the male, the female having 

 fully developed wings ; he alluded to the Perlidce 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. Gr. Barrett and Mr. H. 

 J. Elwes cited instances amongst the Bomhycidce 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 Orohia, obtained by Mr. J. J. Lister in the Seychelles 

 Islands, together with Phyll'mm gelonus. He also exhibited specimens of botli sexes 

 of an Acridiid insect, of the group Proncopides, remarkable for its great general 

 resemblance to the Phasmidce, though without resemblance, 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 organization to portions 

 of the vegetable kingdom 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 Phasmidoe are phytophagous 

 insects. The resemblance to vegetable products reached its maximum of develop- 

 ment 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 com- 

 petent botanist would hesitate to pronounce them to belong to the vegetable 

 kingdom. Dr. Sharp also stated that in some species of Phasmidce, 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 Coenonympha Pamphilus ; also two specimens of Apatura Iris, and two of 

 Limenitis Syhilla in which the white bands were entirely absent. 



The Hon. Walter Rothschild exhibited, and contributed preliminary notes on, 

 some hundreds of Lepidoptera, representative of a collection of some 5000 speci- 

 mens recently made in five weeks, by Mr. W. Doherty, in the south-west of Celebes. 

 Many of the species were new, and others very rare. Mr. Elwes, Colonel Swinhoe, 

 and Mr. S. Stevens commented on the interesting nature of this collection, and a vote 

 of thanks to Mr. Rothschild for exhibiting it was passed by the Meeting. 



Mr. E. B. Poulton gave a lecture, " On the denudation of the Scales in certain 

 Species of Lepidoptera'' and illustrated it by a large number of photographs shown 

 by means of the oxy-hydrogen lantern. Mr. Gr. F. Hampson, Mr. Elwes, and Mr. 

 Poulton took part in the discussion which ensued. — H, Gross, Hon. Secretary.
