G5. E. CORTICINU3 S. (Journ. Acad. Nat 8c., iii., j). 174.) — 

 The second and third joints of the antennae are rounded, erjual. 

 The basal margin of the thorax has a fi.s.sun; each side, near the 

 lateral spines. It varies in .size. The smallest one that I have 

 seen is seven-twentietlisof an imli. Can itbethc iliapar nf Herbst^ 



6G. K. CiNEREU.s Weber. — Second joint of the antoniiaj about 

 half the length of the third: the thorax is more rounded at the 

 sides than the preceding. It varies considerably in size. The 

 basal margin of the thorax ha.s a fissure each side. 



Length from three-tenths to seven-tenths of an inch. 



The former size is rare ; but the more u.sual length is about 

 half an inch. 



This is the vulijaria and pilosus of Melsheimer's Catalogue. 

 It resembles the 6rMn?jj})('.s Zicgler; but the thoracic punctures 

 are rather larger, and less crowded, the thoracic spines are longer 

 and more acute, and the second joint of the antcnnao is a little 

 longer in proportion to the third.* [184J 



*[ Among Mr. Say's manuscripts is a description of the ci'ncrriis, nuder 

 the rejected narao of Jissllis, which, as it contains tlio characters of thia 

 species somewhat in detail, it may be proper to insert here.] 



E. Jissilis. — Brown ; base of the thorax with a fissure near the pos- 

 terior angles. 



Inhabits the United States. 



Body chestnut-brown, punctured, somewhat sericeous with short 

 hairs : head convex : clypeus rounded at tip : antenn.Te rufous ; second 

 joint half as long as the third; ultimate joint not abruptly contracted near 

 the tip: thorax with the lateral edge regularly arcuated, not [184] con- 

 tracted near the spines ; spines rather short and somewhat obtuse, sub- 

 bicarinate ; basal margin, near the lateral spines, with a distinct fissure : 

 elytra with punctured striae, and depressed, minutely punctured inter- 

 stitial lines ; suture somewhat paler : feet dull rufous : tarsi beneath 

 with rather dense hairs : nails pectinated. 



Length over half an inch. 



The thoracic fissures readily distinguish this species. I formerly 

 marked it in my cabinet interrogatively as the brevicollis Ilerbst ; but 

 it can hardly be that species, as no notice^is taken of the fissures. Can 

 it be the cinereus Weber f 

 1836.]
