tip, SO as to appear like two joints : thorax with the puncturos 

 as large as those of" the head, but less dense ; spines uhtusi;, not 

 elongated, destitute of carina : elytra with deep striao, in which 

 are rather large, close set punctures; interstitial lines convex with 

 minute punctures : feet, color of the antennae, honey-yellow ; 

 second and third tarsal joints extended beneath into a membra- 

 naceous, rounded pulvillus. 



Length less than seven-tenths of an inch. 



This species may be distinguished by the obtuse thoracic 

 spines, and the lobed second and third tarsal joints. 



[Belongs to Amjjhrs. — Lec] 



3S. E. iNQUi.NATU.s. — Houey-ycllowish, head and suture 

 blackish. 



Inhabits United States. 



Body small, honey-yellow, with short hair : head dusky or 

 blackish: antennie f»ale : clypcus terminating anteriorly in a 

 rectangle : thorax dusky on the anterior margin ; lateral edge 

 rectilinear ; posterior angles acute ; base each side with an elon- 

 gated fissure : elytra, striae distinctly punctured ; sutural margin 

 widely dusky at base, and tapering to the tip : beneath reddish 

 brown: feet yellowish; tarsi with the penultimate joint only, 

 obviously lobcd. 



Length under one-fifth of an inch. 



This species occurs in I'ennsylvania, and Dr. Harris obtained 

 it in New Hampshire, and from North Carolina. 



[I received from Dr. Harris a specimen of Dohpius pauper 

 Lec, as this species, but as the tarsi are not lobed it cannot be so 

 referred : I am rather inclined to believe it the same as ElaUr 

 recticoUis Say, which is an Adraslus. — Lec] 



39. E. MEMNO.NIUS. — Brown, more or less dark : antcnnaj ru- 

 fous, compressed; length of the joints at least twice their ter- 

 minal breadth ; longer than the thorax : head densely punc- 

 tured ; front concave, anterior edge dej)ressed in the middle by 

 the concavity, but still elevated : thorax densely, not confluently 

 punctured, convex, laterally arcuated, widest in the middle ; pos- 

 terior angles very little excurvcd, and at their tips somewhat in- 

 curved ; carinated line nearly parallel with the edge, elevated 

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