Common throughout Indiana, May 11 Tu3y 25. New Eng- 

 land, New York and New Jersey; June September. Range the 

 same as that of barlita. Breeds in and beneath the bark of elm. 

 According to Packard (1800, 220), "The burrows are about an 

 inch and a half long running with the grain and in the cambium 

 layer. From the cell at the end an exit pierces the bark as far 

 as the outer layer. The beetles usually attack the upper branches, 

 but several small elms were found with the bark of the trunk un- 

 dermined nearly to the ground." J/. jx.ilUda Say, described from 

 Indiana, is a pale form of the male of unnicoUls. Three males at 

 hand from Ithaca, N. Y., are wholly black.
