SOME NORTH AMERICAN INSECTS. 175 



with large, very dense punctures : front a little concave : chjpeus not 

 prominent, rather depressed between the antennae: antennae, a little 

 paler ; second joint rather more than half as long as the third ; terminal 

 joint abruptly smaller near the tip, so as to appear like two joints : 

 thorax with the punctures as large as those of the head, but less dense; 

 spines obtuse, not elongated, destitute of carina: e/«/^ra with deep striae, 

 in which are rather large, close set punctures ; interstitial lines convex, 

 with minute punctures : feet^ colour of the antennae, honey-yellow ; se- 

 cond and third tarsal joints extended beneath into a membranaceous, 

 rounded pulvillus. — Length less than seven-tenths of an inch. 



This species may be distinguished by the obtuse thoracic spines, and 

 the lubed second and third tarsal joints. 



38. E. inquinatus. Honey-yellowish, head and suture blackish. — 

 Inhab. U. S. 



Body small, honey-yellow, with short hair: ^eatZ dusky or blackish: 

 antennx pale : clypeus terminating anteriorly in a rectangle : thorax 

 dusky on the anterior margin ; lateral edge rectilinear; posterior angles 

 acute ; base each side with an elongated fissure: elytra, siriad distinctly 

 punctured ; sutural margin widely dusky at base, and tapering to the 

 tip: beneath reddish hrown: feet yellowish ; tarsi with the penultimate 

 joint only, obviously lobed. — Length under one-fifth of an inch. 



This species occurs in Pennsylvania, and Dr Harris obtained it in 

 New Hampshire, and from North Carolina. 



39. Fi. memnonius. Brow^n more or less dark: antennae rufous, 

 compressed ; length of the joints at least twice their terminal breadth; 

 longer than the thorax : head densely punctured ; front concave, ante- 

 rior edge depressed in the middle by the concavity, but still elevated : 

 thorax densely, not confluently punctured, convex, laterally arcuated, 

 widest in the middle ; posterior angles very little excurved, and at their 

 tips somewhat incurved ; carinated line nearly parallel with the edge, 

 elevated and acute; basal edge with an acute sinus near the posterior 

 angles: elytra with punctured impressed striae; punctures nearer each 

 other than their own length ; interstitial spaces convex, densely punc- 

 tured ; third and fourth striae abbreviated and confluent at tip ; apicial 

 margin a little elevated: beneath, margins and feet paler. — Length less 

 than four-fifths of an inch.
