Entomological Society, 



of Trinodes biitus, and a specimen of Acrognathus mandibularis, a Coleopterous insect 

 new to this country, taken at Darenth Wood, about three years ago. 



Mr. Westwood exhibited a fine specimen of the Carpocapsa, which he had 

 recently bred from the Mexican "jumping seeds," for which he proposed the 

 name of 



Carpocapsa saltitans.

Mr. Westwood exhibited a drawing, lately received by Mr. Spence from India, of 

 the winged male and apterous worker of a species of Dorylus, together with the larva 

 and pupa of the latter, which had been communicated to Herr Neituer by the Hon. 

 Walter Elliot. The male is of the ordinary Dorylus form, that sex having only 

 hitherto been observed, but the worker is a species of Mr. Weslwood's genus 

 Typhlopone. Herr Neitner's letter is as follows : — 



" Rambodde, Ceylon, March 24, 1858. 



"W. Spence, Esq., London. 



Dear Sir. — When at Madras, a few weeks ago, my friend the Hon. Walter 

 Elliot showed me an entomological sketch, a copy of which I beg to enclose, asking 

 me what the insect represented was. There can be no doubt that it is a Dorylus, and 

 of great interest, as it represents two sexes, and as Mr. Elliot has observed their do- 

 mestic habits. With regard to the latter, Mr. Elliot states that a couple of years ago 

 he found a large society of these insects at Collenada, near Coringa, north of Madras, 

 at about 17° N. L. They lived in the manner of ants, under the stone foundations of 

 a house built on loose sand, within half-a-mile of the sea-coast: the society was very 

 numerous. Mr. Elliot brought away a number of the insects, and had a drawing 

 made of them by a native draughtsman : the enclosed sketch is a copy of it, also made 

 by a native draughtsman. [The drawing represents the male insect of the natural 

 size and in different positions, with magnified details of the antennae, legs and geni- 

 talia ; also the worker of the natural size, and magnified with details, and with the 

 larva and pupa]. There can be no doubt that these insects are closely allied to the 

 social ants. The difference in size of the male and the worker is very remarkable. 

 The female remains still to be discovered : still I feel confident that the enclosed 

 sketch and Mr. Elliot's observations will interest you as much as they have interested 

 me, and will be generally considered as an acceptable addition to the natural-history 

 of the genus Dorylus." 



Mr. Thwaites, by whom Herr Neitner's letter was transmitted to Mr. Spence, adds 

 that "it is very interesting to find Shuckard's conjecture that Typhlopone would prove 

 to be of the Dorylus family verified. Shuckard's paper on the subject is in the
