developed in the male than in the female. Mr. C. G. Barrett 

 and Mr. H. J. Elwes cited instances amongst the Bombycida 

 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 appa- 

 rently 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 Phasmida, though with- 

 out resemblance, so far as is know n, to any particular species. 

 In reference to the Phyllhnn, Dr. Sharp called attention to 

 the fact that the similarity of appearance of parts of their 

 organisation to portions of the vegetable kingdom was accom- 

 panied 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 foli- 

 aceous expansions of its fellows, although the PhasmidcB 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 pro- 

 nounce them to belong to the vegetable kingdom. Dr. Sharp 

 also stated that in some species of Phasmida it was easy to 

 obtain the egg by extraction from a dried specimen. 



Mr. Barrett exhibited, for Major J. N. Still, a specimen of 

 Notodo)ita bicolorn, which had been captured in a wood near 

 Exeter. Major Still had stated that the captor of the speci- 

 men was unaware of the great rarity of the species. Mr. 

 Barrett also exhibited, for Mr. Sydney Webb, some remark- 

 able varieties of Aryynnis adippe and Ccenonympha pamphilus ; 

 also two specimens of Apatnra irin, and two of Limenitis 

 sybilla in which the white bands were entirely absent. 



The Hon. Walter Rothschild sent for exhibition some 

 hundreds of Lepidoptera, representative of a magnificent 

 collection of about 5000 specimens recently made in five
