March 21. 



Thomas Bell, Esq., President, in the Chair. 



Frederick D. Dyster, Esq., M.D., and John Thomas Syme, Esq., 

 were elected Fellows. 



Mr. Ward, F.L.S., exhibited living specimens of Gymnogramma 

 leplophylla, Desv., grown in one of his cases from mould taken from 

 its native habitat in Jersey in September 1853; and observed that 

 this plant, like the Trichomanes, attains a much greater luxuriance 

 in a closed case than in its native situation, and lasts very much 

 longer. 



Mr. Adam White, F.L.S., exhibited a specimen, from the collec- 

 tion of Mr. Aspinall Turner, of Hypocephalus armatus, Desm., and 

 made some observations on its structure and affinities. 



Mr. Westwood, F.L.S., exhibited a small collection of insects of 

 most of the different orders, collected at Darjeeling and in other 

 parts of India by Capt. Slater of the Bengal Army. Among them 

 he particularly noticed a rare species of Paussida, Jumnos Ruckeri, 

 Bombyx Huttoni (the moth which jjroduces the new kind of Indian 

 silk), Epicipera sp. (a moth having all the appearance of a species of 

 Papilio), an apparently new species of Papilio resembhng the genus 

 Euplxa, &c. 



Read a paper " On the genus Myrmica and other Ants." By John 

 Curtis, Esq., F.L.S. &c. 



After referring to the more important published works on the sub- 

 ject of Ants, such as those of Latreille, Nylander and Foerster ; and 

 to the difficulties attending the study of this family on account of 

 the different phases under which each species appears, Mr. Curtis 

 proceeds to enumerate the British species of Myrmica, Stenamma and 

 Myrmecina, and to describe and figure some English Myrmicce, which 

 are either new or imperfectly known. He commences by dividing 

 the British FonnicidcB as follows : — 



A. with a single scale upon the petiole. 

 Palpi 6- and 4-jointed. 



Mandibles of female elongated .... 1. Formica, hinn. 



Mandibles of female triangular .... 2. P oner a, Latr.
