June i. — The commencement of a Paper on the Paussidce, afantily of 

 Coleopterous Insects, by J. 0. Westwood, F.L.S., &c.,\vas read. The 

 insects composing this singular family, remarkable especially for the pe- 

 culiar structure of their antennae, inhabit the tropical regions of the old 

 world, and do not exceed half an inch in length. In the year 1798, a 

 paper by Professor Afzelius, upon the same group, was read before the 

 Linnean Society, in which that distinguished naturalist indicated no more 

 than five species. Since his time several important additions have been 

 made by other entomologists ; and Mr. Westwood has, in the present 

 paper, increased the number of species to twenty-three, exclusive of those 

 which had been incorrectly referred to the family by previous writers. 

 In addition to the genus Paussus, originally established by Linnaeus, he 

 admits Hylotorus, Dalra., and Cerapterus, Swed. ; and adds three new 

 genera of his own formation. The following is his Synopsis of these 

 subdivisions :
