marginibus lateralibus integris, elytris minute longitudinaliter granulatis ; singulo

This species appears to approach near to A. bicolor, Klug. It is entirely co- 

 vered with very minute granulations, those of the elytra being elongated and 

 almost confluent. It is black, with a pitchy tinge at the sides, and is clothed 

 beneath with pale brown hairs. The disc of the head is neither impressed 

 nor tuberculated ; the angles in front of the eyes are very acute, and the front 

 of the disc is produced into an acute and porrected conical point, the anterior 

 angles in front of the antennae being also acute ; the mandibles have a strong 

 notch at the sides, the margin of each division formed by the notch being 

 rounded. The middle of the pronotum is deeply excavated, the excavation 

 being somewhat oval ; its deepest part is smooth, but the sides are granu- 

 lated ; the sides of the excavation are edged with a narrow raised polished 

 carina on each side, which converge towards each other behind, and are 

 rather angulated outwardly near the middle : there is no oblique, polished, thin 

 raised line between each of these two polished edges and the hinder angle of 

 the pronotum, the lateral margin of which is entire, having a small impression 

 on each side near the margin. The elytra are but slightly setose, the shoulders 

 and a spot near the apex of each are polished, and each is marked (when seen 

 through a lens) with a very slender raised line close to the suture, and two 

 others impressed on the disc, which are more distinctly visible at the base. 

 The underside of the body and legs is pitchy, thickly clothed with pale yel- 

 lowish brown hairs.

 noti angulis posticis prominentibus ; tuberculo ovali ante medium carinis duabus obli- 

 quis lateralibus lineisque duabus laevibus ante angulos posticos, elytris substriatis. — 

 Long. corp. lin. 4j.
