 Mr. \\^estwood exhibited a specimen of Serropalpus striatus, a 

 beetle not hitherto noticed as British, which he had received from 

 Mr. Plant of Leicester, by whom it had been recently obtained in 

 that neighbourhood. 



The following memoirs were read :— 



'* Notice of the occurrence of a species of Sir ex in a wooden build- 

 ing long erected," communicated by Sir W. Clinton and the Bishop 

 of Norwich to Mr. Spence. 



The wood- work of a conservatory belonging to Sir W. Clinton, 

 which had been erected ten years, having been observed to be under- 

 going what appeared to be the dry-rot, it was partially taken down, 

 and in the interior of one of the rafters of close-grained Memel deal, 

 several pupae of an insect, supposed to be a foreign species of Sirex^ 

 were discovered within burrows filled with wood- dust, and, in the 

 parts where the pupse were observed, lined with the fragments of 

 wings and other parts of the perfect insect ; and as no external ori- 

 fice was detected, it is supposed that the insect proceeded from eggs 

 laid in the rough timber before it was framed, and that there had 

 been a succession of them. The insect was not however forwarded 

 for inspection, so that doubts must be entertained both as to its 

 species and even family, as the account seems in some respects to 

 agree with the habits of some of the wood-boring species of the Lin- 

 nsean genus Sphex.
