is the case with the Gymnopleuri, rather than that they should be thus 

 symmetrically formed by the irregular-shaped larva, whilst, on the 

 other hand, the perfectly oval cells of the Andrence then upon the table 

 were instanced as supporting a contrary opinion. 



Mr. Westwood made some observations in opposition to Mr. 

 Thompson's assertion of a general metamorphosis throughout the 

 Crustacea. And Lieut.-Colonel Sykes stated that he had found the 

 Land Crabs in India several hundred miles inland, and had never 

 observed them to make annual migrations to the shore, the vast 

 Ghauts preventing such a journey. Mr. Sells also made a similar 

 observation respecting the Black Crabs of the West Indies, which 

 he had observed several thousand feet above the level of the ocean 

 in the middle of the island of Jamaica. 



Mr. Pickering's observations upon the CEconomy of the Stre- 

 psiptera called forth extended remarks from various Members, by 

 some of whom it was suggested that it was in the midst of the pollen- 

 paste in the cells of the bees that the eggs of the Stylops are depo- 

 sited, and that the larvae, when hatched, burrow into the larvae of 

 the bee ; by others, that it was in the bee's eggs ; by some, in the 

 body of the larvae of the bee ; and by others, that they were depo- 

 sited in flowers, from whence the bees, in search of pollen, might 

 accidentally carry them into their cells. Mr. Pickering, in reply to 

 the different observations made upon this subject, stated that his 

 opinion that the eggs were deposited in the eggs of the bees remained 

 unshaken, as it could only be during the short period previous to the 

 closing of the cell, after it had been filled with pollen-paste, that 

 the egg could possibly be introduced into the bee's nest. He, how- 

 ever, admitted that with respect to Xenos the case might be dif- 

 ferent, since the cells of the Polistes (in the bodies of w'hich it is 

 found,) are left open, in order that the gregarious wasps may the 

 more readily feed their larvae contained therein, and which would 

 consequently render the deposition of the eggs of the Xenos within 

 the larva of the wasp more probable. Relative to the genera of 

 Hymenoptera attacked by the Strepsiptera, the Rev. F. W. Hope 

 stated that M. Van Heyden of Dantzig had shown him specimens 

 of two species of Cerceris infested by a distinct genus of this order. 

 And Mr. Westwood read an extract from a Letter received by him 

 from Robert Templeton, Esq., relating to the capture of Elenchus 

 tenuicornis, K., in the nest of a Bombus. 



The Rev. F. W. Hope, as Treasurer for the past year, laid his Ac- 

 counts upon the table, and the six following Gentlemen were elected 

 Auditors of tlic same, namely, Lieut. -Col. Sykes ; Messrs. Stephens
