Ix JOURNAL OP PROCEEDINGS. 



of being placed on the leaves or stems, were situated on the peduncles 

 of the flowers, giving the tree the appearance of bearing branches of 

 unripe currants, and which were probably caused by the Cynips quer- 

 cus petioli. 



The President stated that he had received a letter from Mr. R. 

 H. Lewis, M.E.S., dated from the Cape of Good Hope, stating the 

 little success he had met with in his entomological researches in the 

 neio"hbourhood of the Cape, and mentioning that he had noticed some 

 of the species of Anthia, which seemed constantly to reside under 



dung. 



Mr. Kirby suggested that it was probably for the purpose of feed- 

 ing upon the insects which frequent such situations that the Anthi<s 

 resorted to such a habitat. 



The following Memoirs were read : 



" Notice relative to the JEpus fulvescens and other submarine 

 Coleopterous Insects." ByW. Spence, Esq., F.R.S. (See p. 179.) 



" Account of the Habits of the Land Crab of the Deccan, by Lieut. - 

 Colonel W. H. Sykes. With a description of the Species Thelpkusa 

 cunicularis." By J. O. West^vood, F.L.S., &c. (See p. 181.) 



" Descriptions of various Species of Crustacea from the island of 

 Mauritius." By Robert Templeton, Esq., R.A. (See p. 185.) 



In the discussion which ensued, Col. Sykes, in answer to an en- 

 quiry by Mr. Kirby, stated that he had met with the Land Crabs in 

 the Deccan in a very young state and very small size, and that in 

 this state they resembled the full-grown individuals. 



With reference to the subject of submarine respiration alluded to 

 by Mr. Spence, Mr. Westwood observed, that the observations of 

 the former appeared to confirm the opinions of certain physiologists, 

 that the distribution of the Arachnida, founded upon the variation 

 of the respiratory system, into Pulmonaria and Trachearia was not 

 entitled to so much weight as others had given to it, and he read a 

 passage from Mr. Jenyns's report on Zoology, not then published, 

 upon the same subject, and also stated the nature of M. Duges' re- 

 cent observations upon the nature of the respiratory system in the 

 genera of spiders Segestria and Scylodes, read before the French 

 Institute, which had been found to possess a compound apparatus 

 for respiration both pulmonary and trachean. 



The President stated that, in addition to the insects mentioned by 

 Mr. Spence as capable of remaining for a great length of time under 

 the surface of the ocean, the Hesperophili, Heteroceri, Lhnnebii, and 

 Epaphius secalis, as well as other Bembediida, were similarly sub- 

 marine in their habits. ' 



The subject of the impregnation of the eggs of insects was again
