SOME NORTH AMERICAN INSECTS. 167 



7. E. rubricoUis, Herbst, N"ob. (Journ. Acad. Nat. Sc). This is 

 the verticinus, Beauvois, but I do not know which has the priority.* 



8. E. limbalis. Thorax fulvous, disc black; elytra blackish, with a 

 testaceous margin. — Inhab. U. S. 



Head blackish ; ardennx wide, deeply serrate ; three basal joints 

 taken together not longer than the fourth joint ; second and third very 

 short, equal transverse : thorax fulvous-testaceous : disc in the middle, 

 basal and posterior part of the lateral margin black : elytra testaceous 

 all around and blackish along the rhiddle: beneath blackish piceous; 

 pectus with an oblique, fulvous spot near the posterior angles : feet 

 piceous. — Length less than half an inch. 



This is the limbalis of Melsh. Catal.,and I have it noted in my MSS. 

 interrogatively as the limbalis of Herbst, but I have not now his work 

 to refer to. 



9. E. ectypus. Blackish brassy ; antennse and feet rufous ; thoracic 

 spines very short. — Inhab. U. S. 



Blackish or dark brown, tinged with brassy : clypeus very obtuse, 

 almost truncated before, not appressed ; above plane, with two obsolete 

 indented lines : antennae dark rufous, not dilated, and hardly serrate ; 

 second joint more than two-thirds the length of the third ; terminal 

 joint not abruptly contracted near the tip: thorax convex; dorsal line 

 obvious ; spines short, their excurvature hardly obvious, carina nearly 

 parallel with the exterior edge : scutel a little convex : elytra with 

 punctured striae; interstitial spaces with numerous, small, definite, or- 

 bicular punctures: feet rufous: tarsi simple. — Length nine-twentieths 

 of an inch. 



It may be distinguished from the appresifrons^ Nob., which it re- 

 sembles, by the more convex thorax, of which the spines are much 

 shorter and not much excurved ; the antennae are more slender, and 

 the terminal joint is not abruptly narroAved near its tip, and the punc- 

 tures of the interstitial spaces of the elytra are obviously orbicular, and 

 definite. 



10. ^.pyrrhos, Herbst. Elongated : the thorax is narrow, the spines 



* Dr Harris remarks that Herbst's name undoubtedly has the priority ; for that of Palisot 

 de Beauvois does not seem to liave been sanctioned by a description.
