regular punctures near the suture : suture and edge all around 

 and spot on the humerus blackish-green : antennae and palpi fer- 

 ruginous. 



Length over half an inch. 



This insect and the preceding may be only varieties ; never- 

 theless, having three specimens that are similar to each other, I 

 may state that it differs from A. gemella nob., in the more ob- 

 viously punctured thorax, in not having the striae of the elytra 

 so obviously in pairs, and in the color. 



HEGETER Latr. 



H, PUNCTATUS. — Thorax transverse ; elytra punctured, and

Inhabits Mexico. 



Body black, densely punctured : antennse and palpi piceous ; 

 terminal joint of the maxillary palpi rather large : thorax trans- 

 verse, convex : elytra irregularly punctured, and with regular 

 series of punctures : feet piceous.

E. iN^QUALis. — Body inequal, with elevated points and lines, 

 and indentations and punctures.

Body black, oblong-oval; head minutely rugose, with an obtuse 

 indentation each side: thorax inequal, with [183] elevated obtuse 

 lines and indentations, and numerous small, elevated dots ; pos- 

 terior angles acute : elytra with many small elevated dots, and 

 deeply impressed, distant punctures; several elevated, obtuse^ 

 abbreviated lines, of which the largest one is near the middle 

 and extends to the posterior declivity; on this declivity are three 

 large, elevated tubercles ; an abbreviated line extends from the 

 humerus, and a very short basal one is nearest the suture: 

 beneath, with numerous, small, elevated dots. 



Length three-fifths of an inch. 



This occurred in abundance in an elevated situation, under old 



logs.
