closely punctured; medial impressed line only apparent in the middle and at 

 base ; sides rectilinear from the tip of the hind angles to a little before the 

 middle, where they are angularly narrowed to the apex ; posterior angles 

 acute, prominently earinated, with the carinas near the outer edges and 

 slightly oblique : elytra elongated, with the sides rectilinear from the base 

 to near the apex ; inner stria; of punctures obsolete or effaced, four outer 

 ones distinct and placed in rather obtuse or faintly impressed striae, parti- 

 cularly towards the apex ; suture slightly rufous : tip of abdomen reddish- 

 brown : feet and anterior coxa?, rufous. 



Chalcolepidius prasinus. Two specimens, $ and 9 i of an Elater were 

 captured near Baltimore by the Rev. Dr. Morris, the $ is now in my col- 

 lection, and is no other than a specimen of a species, inhabiting South Ame- 

 rica, described by Prof. Erichson in Germar's << Zeitschriftfiir Entomologie," 

 Vol. iii., p. 85, under the above name. This species may probably prove 

 to be Elater riridipilis, Say. Ann. Lye. Nat. Hist. New York, Vol. i. No. ix. 

 p. 257. and also noticed in the Trans. Amer. Phil. Soc. Philad., Vol. vi. p. 

 166, No. 5. 



Athous, Eschsch. 



1. A. vagrajit. Fuscous; beneath and feet castaneous ; thorax oblong- 

 quadrate, with four obsolete impressions. — 9 1. long, 3 1. wide. Pennsyl- 

 vania. 



Elongate, dark chestnut-brown above : head clothed with yellowish pile, 

 rugosely and profoundly punctured, with the clypeus anteriorly deflexed and 

 the edge only elevated in front of the eyes, which are black and glossy ; 

 antenna?, some longer than the thorax, slender, second joint not half as long 

 as the third, which is equal in length to the fourth, terminal distinctly subu- 

 late or furnished with an accessorial point : yellowish, pubescent : thorax 

 oblong-quadrate, somewhat convex, with the sides rectilinear, or somewhat 

 undulated, very slightly rounded in the middle and faintly contracted before 

 the posterior angles ; yellowish pubescent, densely and profoundly punc- 

 tured; each side of the middle with two obsolete indentations, the two an- 

 terior ones are placed behind the anterior margin, the two posterior ones a 

 little before the basal margin ; medial channel somewhat apparent in the 

 middle ; posterior angles robust, slightly excurved, subacute, carinate, ca- 

 rina? fine, long, almost parallel to the lateral edge : scutellum densely yel- 

 lowish pilose, with the disk longitudinally convex, punctured and glabrous : 

 elytra somewhat widest behind the middle, obtusely transversely indented 

 behind the basal region ; finely punctate-striate, the interstices broad, flat, 

 minutely and indefinitely punctured, and transverse-rugulose towards the 

 base, clothed with very short and fine yellowish pile; apex acutely rounded 

 beneath and feet some lighter colored than above, densely minutely yellowish 

 pubescent. Resembles somewhat A. memnonius, Hbst., but is narrower 

 and otherwise distinct from that common species. 



2. A. sequalis. Fusco-testaceous ; thorax oblong-subquadrate — 9 1. long. 

 3 1. wide. Pennsylvania.
