256 A RARE COLEOPTERA PAPER OF T. W. HARRIS 



"Body piceous black, densely punctured, and with elongated, brassy yellow 

 scales. Head retracted to the eyes within the thorax, indented at the Ijase of 

 the rostrum. Rostrum as long as the head and thorax, slender, almost fili- 

 form, arcuated, sUghtly dilated over the origin of the antenna?, piceous, mi- 

 nutely and remotely punctured. Antennae inserted behind the middle of the 

 rostrum, piceous, club rufous; third joint (second of the funiculus,) two thirds 

 the length of the preceding, and twice the length of the following joint. 

 Thorax, in the middle, longitudinally elevated, or almost carinated, covered 

 with linear-lanceolate scales, which converge from the sides towards the central 

 carina. Elytra with acute, remotely punctured striae, and flat interstitial 

 lines, each one of which is covered with large, superficial, confluent punctures, 

 and three series of linear-lanceolate scales; an oblique elevation or callus 

 before the tip of each elji;ron. Body, beneath, more densely covered with 

 whiter, shorter, oval scales. Breast, before the anterior legs widely indented, 

 not canaliculate, unarmed."

"Body black, densely punctured, and with Unear-lanceolate yellowish or dirty 

 white scales. Head indented at the base of the rostrum, retracted to the eyes 

 within the thorax. Rostrum rather longer than the head and thorax, slender, 

 arcuated, shghtly dilated in the middle. Antennae inserted just behind the 

 middle of the rostrum; second joint (first of the funiculus,) longer than the 

 third and fourth taken together; the fourth joint rather shorter than the third. 

 Thorax obtusely carinated, covered with linear scales converging towards the 

 central carina. Elytra with acute, remotely punctured stria, and flat, con- 

 fluently but vaguely punctured interstitial fines, on each of which are three 

 rows of hnear scales. Scutel and posterior lobe of the thorax, in front of it, 

 with white scales. Body, beneath, more densely covered with oval, whitish 

 scales. Breast deeply and widely indented before the anterior legs, not 

 canaUculate, but with a long, pendent spine in front of each of the anterior 

 coxae. 



" This insect and the preceding one are evidently closely related. Thej' agree 

 in form of the head, rostrum, thorax, and body: the eyes, in both, are large, 

 oval, not prominent, but rather flat, separated above only by the base of the 

 slender rostrum, and below by a still narrower space. The thorax is conical, 

 nearly as long as it is wide, tubulated before, without lobes behind the eyes, 

 bisinuated behind, and produced in the middle of the base before the [Page 

 82] scutel. The elytra, taken together, are triangular, broadest at base, with 

 prominent shoulders, attenuated behind, the tip not truncated nor obtusely 

 rounded, but subacute, and each with a callus before the apex. The hinder 

 legs are ^dder apart than the two other pairs ; the tibiae are truncated and with 

 an exceedingly minute hook at the inside of the extremity; and the thighs are 

 unarmed." (This is 8928 [Henshaw], Gerceus picumnis Herbst.)
