This species was very abundant in the woodshed of the old 

 farmhouse where I was spending my vacation and the timbers 

 were fast assuming a serious condition of "powder-post" from 

 their operations. The sticks of beech wood in the shed, which 

 had evidently been piled up for several years in the back tiers, 

 were almost reduced to powder in many cases. In the pine 

 flooring of the attic some species of insect was also working 

 and throwing up a very fine mealy dust into little piles, some- 

 times a quarter of an inch or more in height. These may have 

 been the larvae of the same species as adult specimens were 

 found in spider webs and on the windows of the attic. 



In view of the great difference in the rate of progress be- 

 tween these specimens of Hadrobregmus and the unspecified 

 Scolytid mentioned in the note referred to, I have concluded 

 that they must represent the tortoise and the hare of the wood- 

 boring Coleoptera. 



I am wondering what becomes of the debris that the pur- 

 sued Scolytid dislodges.

 band rather broad, thick, long; circumfili at the basal third and api- 

 cally ; terminal segment somewhat produced, obconic, tapering to a nar-
