 heetle."

Tln-oughout the State; scarce. IMay 27-Au- 

 giist 1!). It is nocturnal and occurs ahout 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, \\'ith 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 throu'^rh its transformations within this cell 

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

 southern Indiana, as the al)ove dates show, they begin to appear a 

 month earlier.
