Mr. Strachan, late resident at Sierra Leone, exhibited several 

 beautiful Coleopterous insects collected at that settlement, includ- 

 ing a male of GoUnthus Torquatus of Drury (another specimen of 

 which is in the Collection of Mr. Joseph Hooker), and which he 

 described as of very great rarity, not having been before noticed 

 by any of the collectors of Insects resident there. The specimen 

 had flown into his room by night. 



Dr. Cantor exhibited some splendid insects collected by him- 

 self in India, including Fulgora clavata, West. ; an apparently new 

 species of the same genus allied to F. candelaria, a large new 

 species of Mantisjm, several beautiful moths allied to Gymnauto- 

 cera, a new Macronota allied to M. j)hiUppinica, a new Mimela 

 and Campsosternus, &c. 



Mr. Westwood exhibited a living specimen of the rare saw-fly, 

 Lyda inanita, captured on the 31st May in his garden at Hammer- 

 smith, and stated that for several years he had noticed it on that day, 

 or within a day or two of it. He also exhibited nests made of small 

 portions of rose leaves spirally arranged, found in his garden, and 

 which were formed by the larvge of a species of Lyda, and which 

 he consequently regarded as those of L. inanita, no other species 

 occurring there. 



He also exhibited a series of drawings illustrative of the natu- 

 ral history of Nematus GaUicola, Balaninus SaUcivorus, and Eu- 

 lopeus Nemati, Westw. (a new species of Chalcididce), the latter 

 being parasitic upon the first-named insect. He also exhibited 

 drawings of various new and remarkable exotic insects, upon 

 which he made various observations. (Since published in the 

 Introduction to Entomology in the Naturalist's Library of Sir W. 

 Jardine.) 



Mr. Ingpen stated, in regard to the economy of Sirex duplex 

 which he had brought before the Society at the last meeting, that 

 the joists of the house (from which alone the Sirex had been pro- 

 duced in immense profusion) were entirely of English timber. 



Mr. Shuckard, in communicating the observations of Mr. 

 Thwaites upon Stylops Dalii, added that he had recently obtained 

 a species of Ammupldla from Gambia, which had evidently been 

 infested by a species of Strepsiptera, and that on examining an 

 American species o( Rht/gckium, which exhibited the heads of two 

 Strepsipterous insects protruding from between the rings of the 

 body, he had found the interior of the abdomen to be occupied by
