SOME NORTH AMERICAN INSECTS. 171 



lateral edge a little arcuated; punctures minute; posterior angles short, 

 rather wide, scarcely excurved ; carina short ; basal margin somewhat 

 depressed, with a longitudinal indentation in the middle, and a slender 

 impunctured line extends to the anterior edge : elytra striate, the striae 

 not very obviously punctured, third and fourth confluent before the 

 tip ; greatest breadth posterior to the middle : tibix and tarsi rufous. — 

 Length two-fifths of an inch. 



This species was sent to me by Dr Harris. The particular disposi- 

 tion of the hair on the elytra of the specimen gives the appearance of 

 a broad band at base, another beyond the middle, and a subsutural spot 

 in the middle, blackish. 



24. E. armus. Black ; shoulder rufous. — Inhab. U. S. 



Body black : clypeus with large punctures, somewhat triangularly 

 depressed ; anterior edge obtusely arcuated, distinct from the anterior 

 part of the head: antennse, joints as broad at tip as long, second and 

 third equal, terminal one large, ovate acute, not abruptly smaller to- 

 wards the tip: thorax convex; punctures rather distant, larger before; 

 lateral edge subrectilinear, a little undulated; posterior angles short, 

 their exterior edge very much arcuated, so that the tip points inward 

 and backward, carina diverging and distant from the edge, and not very 

 obvious: e/y/rawith punctured striae, third and fourth continent before 

 the tip; interstitial spaces punctured ; humerus rufous. — Length one- 

 fourth of an inch. 



Different from scapularis, S., of which the tarsi are lobed. It inha- 

 bits the middle states, and Dr Harris sent me one from Massachusetts. 



25. E. agonus. Posterior thoracic angles very short and rounded ; 

 antennae longer than the thorax — Inhab. Massachusetts, Harris. Penn- 

 sylvania. 



Body violaceous-blackish: clypeus very obtuse before and hardly dis- 

 tinct from the anterior part of the head; punctures small : antennx ru- 

 fous, the tip of the ninth joint reaching the tip of the posterior thoracic 

 angle, third joint a little longer than the second, which is globular; 

 terminal joint obtuse at tip : thorax with small punctures, and, like 

 the head, with prostrate hair; lateral edge slightly arcuated to each 

 extremity ; at base an impressed line in the middle, and an oblique one 

 each side; posterior angles very short, obtusely rounded: elytra with
