"and cool climate of that country, our lO-lined potato-beetle would thrive there 

 " even if imported. There cannot be much doubt that the insect will rather enjoy 

 *' the more temperate clime ; for while it thrives best during comparatively dry 

 "seasons, both excessive heat and drought, as well as excessive wet, are prejudicial 

 " to it. It is argued by others that on the continent of Europe our DorypJtora 

 ■"would not thrive if introduced. The idea that the climate of North America is 

 " less extreme than that of Europe, is rather novel to us of the Cis-Atlantic, and I 

 "am decidedly of opinion that they delude themselves who suppose that Doryphora 

 " could not thrive in the greater part of Europe." 



Entomological Society of London: 'Jth, June, 1875. — Sir S. S. Saunders, 

 €.M.G-., President, in the Chair. 



W. A. Forbes, Esq., of South Castle Street, Edinburgh, was elected an Ordinary 

 Member. 



Mr. Briggs exhibited some specimens of Zygcena meliloti, bearing a strong 

 Tesemblanco to Z. trifolii, and mentioned several instances in which the offspring of 

 Z. meliloti exhibited a taint of trifolii blood. He suggested that Z. meliloti might 

 he only a stunted variety. Mr. McLachlan remarked that the insects of the genus 

 hybridized very freely, and alluded to their pairing several times. Mr. W. A. Lewis 

 had noticed that Z. meliloti was by far the most common insect in the New Forest, 

 and as it appeared to have been only discovered of late years, this supported the idea 

 that it was only a stunted variety wliich had been recently developed there. Mr. 

 "VVeir said that he had taken the insect twenty years ago in Tilgate Forest. 



Mr. McLachlan exhibited a portion of a vine-leaf on which were galls of PhyUo- 

 xera vastatrim, the leaf having been recently plucked in a green-house near Loudon. 



The Rev. A. E. Eaton exhibited the insects which he had recently captured in 

 Kerguelen's Island. There were about a dozen belonging to the Coleoptera, Lepi- 

 doptera, and Diptera, besides some bird-lice and fleas. They were all cither apterous 

 or the wings were more or less rudimentary. One of the Diptera possessed neither 

 wings nor hnltfres. 



Mr. Briggs exhibited a specimen of Balias prasinano, which, when taken, was 

 heard to squeak several times very distinctly ; and, at the saiuc time, a slender fda- 

 ment, projected from beneath the abdomen, was observed to be in rapid motion, and 

 two small spiracles below the filament were distinctly dilated. 



The President remarked that he had recently discovered a larva in the body of 

 Andrena Trimmerana, which had a long telescopic process in front similar to that of 

 Conops, and two reniform processes behind. He had frequently found Conops in a 

 species of Dombus, but he had never observed it before in Andrena. Mr. W. Cole 

 remarked on the gi'cat number of different parasites attached to the genus Bombus. 



The Secretary exhibited some specimens of a minute Podura, forwarded to him 

 by the Secretary of the Microscopical Society, having been found on the snow of the 

 Sierra Nevada. 



Mr. F. H. Ward exhibited some microscopic slides shewing specimens of a flea 

 attached to the skin of the neck of a fowl. 



Professor Westwood communicated a " Description of a new genus of Clerideous 

 Coleoptera from the Malay Archipelago." 



Mr. McLachlan read a paper entitled "A sketch of our present knowledge of 

 the Neuropterous Fauna of Japan (including Odonata and Tnchoptera)." 



Part i of the Transactions of the Societv for l875 was on the table.
