Harris's Prionus 



Tragosoiiia Jiarrisii Lee. 



A large, stout, brownish beetle about 1J4 inches in length, and closely resembling a 

 rather slender prionid, breeds in pine stumps. 



This species, according to Wickliani, is coiisiden-d 1)\- sonn; writers as 

 identical with the North European T. depsarium Linn. He character- 

 izes it as a curious h)okirig beetle of elongate form and 

 l)rownish color. The antennae are slender, the prolhora.v 

 small in comparison with the elytra, very hairy and armed 

 on each side with a single sharp tooth, in front of which 

 tile lateral margins are converg(;nt. The eKlra an- shining, 

 ilistinctly punctured and with numerous raised lines. 



This species probably ranges across the continent in i 



the more northern latitudes, having bc-en reported from 



Fort Colville Wash. Leng records it from Newfoundland 



to \'ancouver and Coney Island. The state collection con- fiK-

Criocephalus agrestis Kirby 



A large, brownish black, narrow beetle al)out i im ii long occurs on ])ines in June 

 and July, its white footless grub boring therein. 



The adult insect is a large, brownish black, narrow beetle about 1 inch 

 in length. It may be recognized by the pair of deep thoracic impressions, 

 the fine punctures on the elytra and by the third joint of the hind tarsi 

 being two thirds longer than Avide, emarginate for about one half its length. 

 This beetle closely resembles A s e m u m m o e s t u m 1 laKl, though twice 

 as large and with longer, more slender antennae. This species is evidently 

 very abundant in Quebec, since a large series was taken at Murray Bay 

 by Rrastus Corning in July or August 1878. It occurs in New York
