shell circulating over the surface of the limb, perfectly analogous to 

 the system of vessels in the ova for the supply of nourishment to 

 the young ; and he had no doubt that this system in the limbs had 

 for its object the reproductive process. In Cancer Pagurus the em- 

 bryo claw was found coiled upon itself within its sac during the 

 process of reproduction, but in the Lobster it was not thus coiled 

 up. 



Extracts from letters were read from Colonel Hearsey and Capt. 

 Boys, addressed to Mr. Westwood, containing various observations 

 on the habits of Indian insects. 



In the former communication Colonel Hearsey mentions the cap- 

 ture of specimens of different species of Paussida by Mr. Benson 

 and Dr. Bacon, also a pair of a new species of CEstrus in copuld, and 

 a new Hister with white spots on the elytra, and other Necrophaga, 

 taken out of the dead body of a Cobra de Capella which had de- 

 stroyed a quantity of Mrs. Hearsey's poultry. 



In the other communication Captain Boys describes the habits of 

 a species of Orthoptera belonging to Latreille's genus Tetrix, about 

 an inch long, which readily takes to the water and dives under it, 

 remaining at the bottom attached to a stone for many minutes to- 

 gether, the dilated foliaceous appendages of the hind legs being well- 

 adapted for swimming, — being the first instance recorded of a nata- 

 torial Orthopterous insect. He also mentions as remarkable, that 

 he had never taken a Lucanus either in the plains of India or in the 

 Vindyah range of hills, although they are not uncommon in the Hi- 

 malayan range, where he always found them feeding on the fungi of 

 various trees, and he had been informed that a friend had even no- 

 ticed them feeding upon excrementitious matter. He had never taken 

 Meloe except at an elevation of 11,000 feet above the level of the 

 sea in the Himalayahs. At an elevation of 14,000 feet he took a 

 Tenthredo ; they were common at 10,000 feet, where the diurnal Le- 

 pidoptera were scarce, and he had not there met with a single true 

 Papilio : several species of Vanessa were more common, and at 

 13,600 feet he took two specimens of a species allied to Doritis 

 Apollo. He had also taken two or three very fine Bolboceri, and 

 a Meyacephala nearly allied to, if not identical with, M. Euphratica. 



Extracts were also read from a letter addressed by Dr. Cantor to 

 the Rev. F. W. Hope, on the insects of Prince of Wales Island ; in 

 which the writer gives the following extract from his note-book re- 

 specting a species of the singular genus Trochoides (of which he also 

 inclosed a highly magnified figure) : — 



" Nov. 7, 1842. Trochoideus Amphora"^, mihi. The night was 

 very dark, and numerous minute insects were attracted by the flame 

 of the lamp, this among the rest. It is the first and the only one 

 of the PaussidcB I ever observed here. Those few which I have seen 

 up in Bengal were captured precisely under similar circumstances. 



* T. Amphora. Plceus nitidus, punciatissimus, punctis mitiutis, tenue se- 

 tosiis, prothorace laterihus marginatis et in medio angulatis, antennis, 

 clypeo,oris partibus et pedibus piceo-testaceis. Long. corp. lin. If,
