52 AMERICAN COLEOPTERA. 



I have taken it at Winnipeg, Manitoba, and have seen specimens 

 from Lake Superior, Illinois, Nebraska, Kansas, Colorado, New 

 Mexico and Texas. 



14. B. COiirusiiin Nobis. — Form morierately robust, convex ; color usually 

 coppery bronze, rarely nearly black, shilling, elytra with the discs obscurely tes- 

 taceous. Head as wide as the thorax at apex, alutaceons ; palpi testaceous, darker 

 towards the tip : anteiiuEe about one-half the lengtli of the body, piceous, the first 

 three joints and base of fourth testaceous. Prothorax rather less than one-half 

 wider than long, not wider at base than apex, feebly transversely wrinkled along 

 the median line, finely rugose at base; apex nearly truncate; anterior transverse 

 impression usually feeble or nearly obsolete, the posterior moderately distinct: 

 basal impressions broad, deep, bistriate ; sides with the margin very narrowly 

 reflexed, arcuate nearly to base, feebly sinuate in front of the hind angles, which 

 are not prominent, subrectangular and feebly carinate. Elytra about one-half 

 wider than the thorax, oblong-ovate, moderately deeply striate; strise distinctly 

 punctate, the punctures usually greenish, less obvious towards the tip; intervals 

 slightly convex, the third with the first dorsal puncture slightly behind the mid- 

 dle, the second about one-fifth from apex. Beneath black, usually strongly tinged 

 with green, shining, the ejiipleurfe more or less testaceous. Legs testaceous. 

 Length .18-.27 inch ; 4.5-6.75 mm. 



The name nitididum, under which this species was described by 

 Dejean, being preoccupied, the above is proposed in its place. 



It has for a long time been regarded as a variety of the preceding, 

 but seems to me too distinct to be retained as such. It differs from 

 coxendix by its more robust form, proportionally longer thorax, with 

 the sides arcuate nearlv to base and feebly sinuate in front of the 

 hind angles, which are subrectangular and not prominent. The 

 elytra are less deeply sti-iate with the punctures usually greenish, the 

 intervals less convex and the discs obscurely testaceous. The legs 

 are entirely pale testaceous. It varies greatly in size. 



It occurs throughout the Eastern and Central States, being known 

 to me from New Hampshire, Massachusetts, NewJYork, New Jersey, 

 Pennsylvania, Maryland, Delaware, Virginia, Georgia, Kentucky, 

 Indiana, the Lake Superior region, Iowa and Colorado. 



Group V. honestum. 



Maxill* with the outer lobe bi-articulate. Frontal grooves single, 

 straight, parallel ; eyes large, prominent. Prothorax subquadrate, 

 more or less narrowed behind; basal impressions unistriate; base 

 truncate, obliquely so each side ; hind angles not carinate. Elytra 

 .with the strife entire, punctate, the eighth distinct and moderately 

 distant from the margin; third stria with two dorsal punctures; 

 humeri subans^ulate.
