dinal lines; deeply inserted into the thorax; surrounded with a coro- 

 net of long incurved yellowish hairs on the margin ; antennas pale 

 reddish ; thorax nearly or quite as wide as the elytra, sub-quadrate in 

 form, somewhat rounded in front, the length, which exceeds the 

 width, is almost equal to that of the elytra, punctured dimly on the 

 disk, but more distinctly on the sides; elytra with about ten strise, 

 irregular on the sides, but regular above, composed of small, deep 

 punctures ; interspaces, with a few minute, indistinct punctures ; 

 venter obliquely truncated, black opaque, and with four conic-acute 

 spines, placed three on one segment and one on the following, though 

 sometimes some are found on the segments in front of the one with 

 three. 



Length varies from about one-sixth to one-fifth of an inch ; the 

 width equals about one-half the length. 



There are some other species of this family which are quite inju- 

 rious in some sections to evergreens, especially to pines. As it is 

 possible, some of these may hereafter be found injuring cultivated 

 evergreens in this State, I introduce here a short description of 

 two or- three of the more noted species. 



Hylurgus terebrans — Oliv. (The Boring Hylurgus.) 



The knob of the antennas is sub-globular, and there are but six 

 joints below the knob. It is of a "dull red or fox color, nearly cylin- 

 drical in form, tapering a very little before, obtusely rounded at both 

 extremities, and about one-fourth of an inch in length." The width 

 is two-fifths the length, and the length of the thorax one-third the 

 entire length. 



The larva? devour the inner surface of the bark of - pine trees, bor- 

 ing through it in various directions. 



Hylurgus dentatus — Say. (The Toothed Hylurgus.) 



This is a minute species scarcely one-tenth of an inch long ; of a 

 dark brown color ; the wing cases are rough, with little granulations, 

 which become more elevated toward the hind extremity. 



It infests the red cedar. 



Spec. char. Imago. — Body reddish brown; head plain blackish with 

 short hairs; antennas rufous; thorax blackish, passing into dull rufous 

 at base, with numerous hairs rather shorter than those of the head ; 

 punctured ; elytra dull rufous, Avith numerous short hairs ; striate, 

 the stria; deeply impressed, and giving the prominent basal edge a 

 dentate appearance; interstitial lines rough, with raised points, 

 which are more prominent and distinct toward the tip; beneath, 

 dark reddish brown ; feet rufous. Length nearly one-tenth of an 

 inch. 



Family CERAMpYCHXdE. (The long-horned Wood-borers. 



This extensive family is readily distinguished from the other tet- 

 ramerous families by the following character.- :
