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 with, 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 Bupj^estis, and a shining red 
beetle. ( Platycerus Placidiis ? ) There were several oval 
cases, as large as pigeon's eggs, containing the exuviae of 
beetles, and in one I found a lamellicorn, complete but 
decayed. I afterwards took from an elm a living beetle of 
this species ( Gymnodus Hugosus J, which in size and shape 
much resembles the Rose Chafer f Cetonia Aurata ), 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.
