 growing in these places the larvce evidently feed only upon such 

 decaying material. These, as well as those mentioned before as 

 feeding in old niamu"e, are almost entirely used for bait by the

This beetle is a little smaller than the one just described, and 

 is dark brown, almost black, with wavy impressed lines across 

 the wing-covers, which are made prominent by being filled with
