c 56 Rev. Mr. K 1 R n y"'^ Ohfervaiions upon Infdls that prey upon Tmber, 



Mr. Trimmer thinks that thcfe infe£ts fly only during the night, 

 as in the day-tiiiie he always found them (landing upon the piece 

 of wood from which they had been difclofed. The cafe is different 

 with Ccramhyx circuatus, which, as I obfcrved before, flies at mid- 

 day : but perhaps this circumftance may depend much upon the 

 ftate of the atmofphere, or the hour of the day ; for many infedls 

 have their certain hours for flying; a fmgular inftance of which 

 I had once an opportunity of witnefllng. In the beginning of 

 July 1793, about ten o'clock in the morning, as I was paffing 

 through a meadow, I was furprifed with the appearance of what 

 at firfl leemed to me to be myriads of bees flying about the hedges 

 and trees ; but, upon taking fome of them, they proved to be Scara- 

 bceus argenteus {Melolontha argentea Fab.) ; upon my return through 

 the fame field, a little after noon, I was afl:oniflied to find that of 

 this infinite hoft of infctSts not a fingJe one was to be feen. 



I have now communicated all the obfervations which Mr. Trim- 

 mer made with refpe6l to rhe hidory of this infe£l; thefe I hope 

 will not be thought unworthy of the attention of the Linnean So- 

 ciety, fince they furnilli an ufeful lefibn in CEconomics, and fupply 

 an additional proof of the utility of the ftudy of Natural Hiftory, 

 and to what good purpofes it may be direfted. 



Mr. Trimmer, when he came to Barham, brought with him fpe- 

 cimcns of this infeft in all its fiiates, as alfofome pieces of the wood 

 that had been attacked by it, from which I employed my ingenious 

 friend the Rev. Peter Lathbury, F. L. S. to make the drawings 

 which accompany this paper. Nothing now remains but to clofe 

 this account with a defcription of each flate of the infccf.
