Frequently taken in the Journey from New York to Cumberland-house, and 

 also in Lat. 65°. Mr. Say says it is very destructive to many species of the genus 

 Pinus. 



DESCRIPTION. 



Body cylindrical, deep chestnut, glossy, hairy underneath. Head above with scattered granules ; 

 nose fringed with yellowish hairs ; antenna? testaceous : prothorax rather oblong, angles rounded, 

 anteriorly granulated with minute elevations, posteriorly punctured with scattered punctures, hairy 

 next the head and on the sides : elytra hairy on the side, with five rows of transverse punctures next 

 the suture, which reach only to the truncated part ; punctures of the side and apex scattered ; apex 

 truncated obliquely and excavated, with the external edge of the excavation armed with four denticles, 

 of which the second and third are the largest : legs pale chestnut ; tarsi testaceous. 



In the other sex? the elytra are entire and unarmed, and the dorsal rows of punctures on the 

 disk of the elytra are more numerous. 



Variety B. Entirely rufous, or pale-chestnut. 



XCVII. * Genus APATE. Fab. 



Antennae with a large rather ovate, hairy, solid compressed knob; with an elongate, clubbed scape: 



subglobose-pedicel ; stalk with four or five indistinct joints. 7 

 Eyes bipartite, immersed, with the lobes connected by a series of lenses. 8 

 Front in one sex excavated into a concavity, in the other plane. 



6 I consider those Xylotrypa as forming this family which have capitate antennas ; those in which they terminate in an 

 elongated knob of three joints, as Bostrichus, &c. I denominate Bostrichida.
