200 THE ZOOLOGIST. 



both sexes of an Acridiid insect, of the group Proscopides, remarkable for 

 its great general resemblance to the Phasmidce, 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 

 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 

 Phasmidce 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 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 Ccenonympha pamphilus ; also 

 two specimens of Apatura iris, and two of Limenitis sybilla iu which the 

 white bands were entirely absent. 



The Hon. Walter Rothschild exhibited, aud contributed preliminary 

 notes on, some hundreds of Lepidoptera, representative of a collection 

 of some five thousand specimens recently made in five weeks, by Mr. W. 

 Doherty, in the South-west of Celebes. The collection included species of 

 Nectaria, Ideopsis, Saletaria, Limnias, Radena, Tirumala, Euplcea, Lethe, 

 Melanitis, Micalesis, Yphthima, Elymnias, Amathusia, Pseudamathusia, 

 Discophora, Acrcea, Ergolis, Cethosia, Cynthia, Cupha, Terinos, Cirrho- 

 chroa, Junonia, Precis, Rhinopalpa, Xoma, Cyrestes, Hypolimnas, Euripus. 

 Rohana, Parthenos, Neptis, Athyma, Symphadra, Euthalia, Limenitis, 

 Abisara, Huphina, Catopsilia, Eronia, Appias, Omithoptera, Papilio, &c, 

 and several species of Hesperidm. Many of the species were new, and 

 others very rare. Mr. Elwes, Colonel Swinhoe and Mr. S. Stevens com- 

 mented 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-hydrogeu lantern. Mr. G. F. 

 Hampson, Mr. Elwes, and Mr. Poulton took part in the discussion which 

 ensued. — H. Goss, Hon. Secretary,
