June 1.—The commencement of a Paper on the Pausside, a family of 
Coleopterous Insects, by J. O. Westwood, F.L.S., &c.,was read. The 
insects composing this singular family, remarkable especially for the pe- 
culiar structure of their antenne, 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 Linnzus, he 
admits Hylotorus, Dalm., and Cerapterus, Swed.; and adds three new 
genera of his own formation. The following is his Synopsis of these 
subdivisions :

genus, founded on a single undescribed species, Pent. paussoides, Westw.
