 gust 19. It is nocturnal and occurs about or- 

 chards and open woods, the larva? living in the 

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

 of their rotten wood. Harris spenks 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 gne> 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.
