Bores in Pinus ponderosa in Colorado. (A. S. 

 Fuller. Amer. Ent., iii, p. 238.) 



35, Criocephalus nuhilus Le Conte. 



The larva bores in roots of yellow piue (TamDa, 

 Fla.), the beetle appearing in April. (E. A. 

 Schwarz. Amer. Ent., iii, p. 238.) 



36. Harris' prionus. 



Tragosoma harrisii Le Conte. 



Order Coleoptera ; family Cerambycid^. 



A beetle closely resembling Prionus, but with much shorter 

 antennae, only one tooth on each side of the thorax, and several raised lines on the 

 wing-covers. 



This rare insect, which has only been found hitherto in 

 New England and Newfoundland, inhabits New York also, 

 and I infer it to be bred in the pine, having in one instance 

 met with the beetle, dead, under the loose bark of one of 

 these trees. (Fitch.) 



"A specimen of this species was found by Mr. Gibbs east 

 of Fort Colville [Oregon]. It probably extends its range 

 across the continent in more northern latitudes." (Le Conte, 

 Proc. Acad. Nat. Sc. Phil., Nov., 1861, p. 354.) pm ui.—Tra. 



Mr. George Hunt has collected it among the pine forests gosoma har-

Bhagium Uneatum Olivier. 



(Larva, PI. xxi, figs. 1,2.) 



Order Coleoptera ; family Cerambycidce. 



Common in the pitch pine, several often in the trunk of the same tree, excavating 

 a broad irregular patch in the outer surface of the sap-wood, the cavity being mostly 

 filled with sawdust, a yellowish white grub about an inch long, divided into seg- 

 ments of nearly equal length aud width, except the second which is the broadest, and 

 the last which is narrowest with its end rounded ; surrounding itself with a broad 

 oval ring of woody fibers, like short threads, placed between the bark and the wood, 

 in which to pass its pupa state ; changing to a beetle, which lies in the same cell 

 through the winter and comes abroad in the spring ; the beetle 0.40 to 0.70 long,
