144 Entomological Society. 



him at the last meeting, and which was nearly two inches long. 

 The same gentleman exhibited a specimen of the pupa of Sphinx Li- 

 gustri, the head-case of which he had repeatedly disturbed during 

 its change from the larva to the pupa state, and in consequence of 

 which, as it appeared to him, the tongue-case was not developed, so 

 that the pupa resembled that of a Smerinthus instead of Sphinx. 



Mr. Hope exhibited a new species of Phyllium from the Neilgher- 

 ries, which he proposed to name P. Rohertsonii after Mr. Robertson, 

 who had presented a large collection of insects from that country to 

 the Society at the last meeting. 



Mr. Shuckard having read some extracts from his memoir on the 

 f2iva.\\yDorylid(B, since published in the Annals of Natural History, Mr. 

 W. W. Saunders stated that one of his specimens of Dorylus orientalis 

 had been captured in the sunshine, but that the other had entered a 

 lighted room in the evening. Mr. Westwood also objected to several 

 of the views entertained by Mr. Shuckard. (See his Memoir on 

 Typhlopone, since published in the Annals of Natural History.) 



Mr. Westwood also read some " Notes on African Entomology," 

 amongst which the almost complete absence oiHomopterous insects on 

 that continent, and the general uniformity of the insects throughout 

 the entire continent, and the resemblance of many of them to In- 

 dian forms, were especially dwelt upon. The Rev. F. W. Hope also 

 entered into a detail of the reasons which had induced him to reject 

 the plans which had been proposed for the geographical distribution 

 of insects, and to consider the subject as primarily divisible accord- 

 ing to the respective hemispheres. He however considered that the 

 northern parts of America and of the old world formed but one en- 

 tomo-geographical region, which he would call Boreal. The other 

 parts of each hemisphere exhibit a secondary division. The ento- 

 mology of Africa was well characterized by its uniform character, 

 although that of North Africa resembled that of South Europe, and 

 that of South East Africa that of Asia. Mr. Waterhouse also made 

 a variety of observations on the same subject, considering the two 

 hemispheres as primarily distinct. 



June 1st.— The Rev. W. Kirby, M.A., F.R.S., Honorary 

 President, in the Chair. 



Mr. Samuel Stevens exhibited a new British genus of Carahideous 

 Coleoptera allied to Pterostichus, captured by Mr. Leplastrier near 

 Dover. 



Mr. Ingpen, A.L.S., exhibited a mass of minute cylindrical cocoons 

 arranged close together like a piece of honey- comb in miniature, 

 being formed by a small species of Ichneumonid(E {Hemiteles — ?), the 

 upper end of many of which had an aperture, whilst in others the 

 aperture was at the opposite end. They were found on the surface 

 of the ground in his garden at Chelsea. 



The Rev. F. W. Hope exhibited several new and rare Coleoptera 

 and Dipt era from New Holland. 



Mr. W. Saunders exhibited the larva of a species of Oiketicus from 

 the East Indies.
