larly impressed ; antennae and feet du~ky rufous. — 5 I. long; 1| I. wide. Penn- 

 sylvania 



Reddish-brown, rufous pubescent : head nearly as wide as the thorax, densely 

 punctured, with the clypeus porrect, triangularly impressed, margined and ob- 

 tusely rounded at apex; eyes large, prominent, black; antennae fully half the 

 length of the body, slender, not serrate, dull rufous, with the second joint small, 

 hardly half as long as the third, which is nearly as long and robust as the fourth ; 

 terminal joint somewhat thickened towards the tip: thorax oblong, convex, de- 

 ciJ.dly narrower than the elytra, with the sides straight and parallel from base 

 to apex ; finely and densely punctured ; hind angles short, straicht and slightly 

 deflexed : scutel very finely punctured : elytra crenate-striate, with the interstices 

 more convex than flat, finely and distantly punctured: feet dull pale rufous. 



12. A. trivittatus. Fuscous; elytra reddish-brown, with the submargins 

 and suture dusky ; feet testaceous. — 5 1. long; 1| I. wide. Pennsylvania. 



Resembles Eluter viitutus, Fabr. Elongate : head closely and profoundly 

 punctulate, very slightly convex, with the clypeus short, margined, obtusely 

 rounded or almost truncate and piceous or dull rufous at tip ; color of the thorax : 

 antennae color of the feet, hardly as long as the thorax, slender, simple, with the 

 second and third joints subequal, obconic, nearly as long as the fourth and fifth, 

 but less robust; basal joint robust, clavate; palpi color of the antennce: thorax 

 oblong, convex, as wide at base as the elytra, and slightly wider than at apex, 

 with the sides very feebly arcuated from the apex to the hind angles, and there 

 slightly contracted ; posterior angles sub-triangular, short, slightly excurved, 

 hardly carinate ; equally, deeply and densely punctulate, dull reddish-brown, 

 with the margins and hind angles paler: scutellum convex, sparse-punctulate : 

 elytra with the sides parallel from the base to behind the middle, thence gra- 

 dually arcuated to the apex ; punctate-striate, with the punctures numerous, 

 small and profound, and the stria3 fine, the interstices flat, with indefinite yet 

 distinct minute punctures; reddish-brown, with the suture and submargins 

 dusky ; feet, epipleurce and pleurce, testaceous ; tarsi, first joint longer than three 

 following ones united, which are slightly dilated and cushioned beneath; fourth 

 joint very minute. It is rare, and the Eluter trivittatus, of Melsh. Catal. This 

 species does not strictly belong to the genus to which I have referred it. 



13. A. tarsalis. Black ; elytra and feet rufo-testaceous, with the tarsi black; 

 antennas long. — 5 1. long ; 1| 1. wide. Pennsylvania.

 impressed, impression extending to the middle of the vertex, with the anterior 

 edge slightly elevated in front of the eyes, and indented in the middle ; antennae 

 deep black, robust, half the length of the body, with the second joint very 

 small, obconic; third joint as wide as the fourth and a little longer; terminal 

 joint long, slender, subulate; third and following joints compressed : thorax ob- 

 long-subquadrate, moderately convex, black, slightly bronzed, finely and pro- 

 foundly punctured, punctures dense on the middle, confluent on the basal and 

 and lateral margins ; sides almost rectilinear, slightly rounded towards the apex, 

 and faintly contracted before the hind angles, which are obtuse, rather excurv- 

 ed, and not carinated ; medial channel faintly and partially defined : scutel black, 

 flat, punctured : elytra very progressively narrowed from the base to near the 

 apex, which is acutely rounded ; punctate-striate, the interstices somewhat con-
