^\ Throughout the State ; scarce. May 27-Au- 

 Hg. 420. Natural size, gust 19. It is nocturnal and occurs about or- 

 chards and open woods, the larvae living in the 

 hollows of beech, cherry and apple trees and feeding upon the juices 

 of their rotten wood. Harris speaks of them* as being "whitish, 

 fleshy grubs, with a reddish, hard-shelled head closely resembling 

 the grubs of the common dor-beetle. In the autumn each one 

 makes an oval cell of fragments of wood strongly cemented with a 

 kind of glue; it goes through its transformations within this cell 

 and comes forth in the beetle form in the month of July." In 

 southern Indiana, as the above dates show, they begin to appear a 

 month earlier.

 the base Insinuate; elytra longer than wide, their tips rounded;
