Charles. — Yesterday morning, I took an early walk to 

 the maple woods, where I spent an hour very pleasantly. 

 There was a large but quite decayed tree, which I almost 

 pulled down piecemeal. The trunk was pierced w^th many 

 holes, and in nearly every hole were the remains of a Sirex, 

 almost gone to dust, except the crustaceous skin ; a large 

 black and yellow species, resembling S. Gigas. I found 

 remnants of many kinds of beetles, some too far gone to be 

 identified ; but I recognised a Buprestis^ and a shining red 

 beetle. (Platyceru8 Placidusf) There were several oval 

 cases, as large as pigeon's eggs, containing the exuviae of 

 beetles, and in one I found a lamellicom, complete but 

 decayed. I afterwards took from an elm a living beetle of 

 this species (Gymnodus Rugosus), which in size and shape 

 much resembles the Rose Chafer ( Cetonia AurataJ, but is of 

 a dark reddish brown colour : the elytra rough and striated. 

 A strong and offensive musty smell came from it ; and it 

 made a slight creaking sound when held in the fingers.
