A beetle closely resembling Prionus, but with much shorter 
antenme, 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.) 
Mr. George Hunt has collected it among the pine forests 
of the Adiroudacks, northern New York.

Order Coleopteka : family Cerambycidce. 
Common in the pitch pine, several often in the trunk of the same tree, excavatiug 
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 and 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 libers, 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,
