One specimen in Dnry collection from northern Indiana. 

 Taken by him also near* Cincinnati. Of it he says: "This fine 

 large species emerges from dead beech timber in June; the holes 

 are perfectly round and some of them one-half inch in diameter. 

 Many come from a single tree, yet it is very difficult to get speci- 

 mens."
