Notice of the Entomological Proceedings of the Linngean Society 

 during the month of March, communicated by the Secretary, and 

 consistingof "APaperon the Neuropterous Genus E'miiff of Latreille. 

 By J. O. Westwood, F.L.S." This genus is composed of a few exotic 

 species allied to the white ants, but differing from them in the short- 

 ness of the wings, which do not extend beyond the extremity of the 

 body, &c. The anterior tarsi are singularly dilated. It was noticed 

 that each of the three species described presented distinguishing 

 characters of a subgeneric rank, and that each is from a distinct 

 quarter of the globe.

" Continuation of a Memoir upon Succinic Insects." By the Rev. 

 F. W. Hope. 



Dr. Ure, F.R.S., who was present as a visitor at the Meeting. 

 having been called upon by Mr. Hope, stated that at that gentleman's 

 request he had minutely analysed various resins, asserted to contain 

 insects, and that he had ascertained that gum copal (in which no in- 

 sect had been yet clearly proved to exist) never contained Oleum Suc- 

 cinum, and was perfectly soluble ; whereas anim^ (in which alone in- 

 sects had been found by Mr. Hope) was always found to contain the 

 Oleum Succinum in abundance, and could never hitherto be entirely 

 solved ; thus establishing the aflinity of the latter resin with amber, 

 which exhibited similar properties. Dr. Ure entered fully into the de- 

 tails of various experiments made in analysing these substances ; and 

 added, that he had obtained results of great practical utility, by the 

 application of the new ethereal essence of caoutchouc, in which, when 

 united with a little spirits of wine, the anime was almost entirely so- 

 luble, forming a beautiful varnish, which dries in a very short time, 



Lieut. Col. Sykes exhibited a small snake, which had been cap- 

 tured by gum falling upon it whilst moist, and which in its writhings 

 had run itself through with a thorn. He also stated, with reference 

 to Mr. Saunders's communication, respecting the Indian Eumenes 

 (see p. 62.) that this species not only makes its nest in flute-holes, 

 but also that if a house in India remain unoccupied for a few 

 months many of the locks will be blocked up by the nests of the 

 insect. 



He also observed, that Mr. Spence's communication respecting 

 the mode of exclusion of the domestic fly would be received with
