Male. — Form short, feebly shining, and somewhat resembling a 

 small ruficollis; head and pronotum aeneous or cupreous, the head 

 usually green on the front, and the pronotum more reddish on the 

 median part; elytra purplish-black; beneath piceous, with a strong 

 aeneous tinge, and slightly more shining than above. 



Head with the front rather wide, moderately convex, and about 

 equal in width at top and bottom, the lateral margins usually feebly, 

 arcuately constricted at the middle, and with a feeble, broad, more 

 or less interrupted longitudinal groove extending from occiput to 

 epistoma ; surface densely, finely granulose, with a few coarse punc- 

 tures intermixed, becoming somewhat longitudinally rugose on the 

 occiput, and sparsely clothed anteriorly with short, recumbent, whit- 

 ish hairs ; epistoma rather narrow between the antennae, and broadly, 

 but not deeply, arcuately emarginate in front ; antennae extending to 

 near middle of pronotum, serrate from the fifth joint, and the outer 

 joints not longer than wide; eyes large, elongate, and more acutely 

 rounded beneath than above. 



Pronotum about one-fourth wider than long, narrower at base than 

 at apex, and widest at middle or near apical angles ; sides obliquely, 

 or feebly, arcuately narrowed from apex to posterior angles, some- 

 times more or less parallel near the posterior angles, which are 

 rectangular ; when viewed from the side the marginal carina is more 

 or less sinuate, the submarginal carina nearly straight, the two 

 carinae narrowly separated anteriorly, and connected to each other 

 at basal fourth; anterior margin strongly sinuate, with a broadly 

 rounded median lobe; base strongly, transversely bisinuate, with the 

 median lobe only feebly developed; disk moderately convex, with a 

 broad, transverse depression in front of base, so whe^i viewed lat- 

 erally the median line of pronotum is more strongly convex on ante- 

 rior half, with a deep depression on each side along lateral margin 

 near middle, and with more or less distinct, straight prehumeral
