Male. — Form slender, more or less linear, and moderately shining; 

 arftennae and head greenish blue ; pronotum dark bronzy green, with 

 the sides more bluish ; elytra piceous, with a strong greenish or 

 bronzy tinge ; beneath dark bronzy green, and more shining than 

 above. 



Head with the front wide, nearly flat, slightly wider at bottom than 

 at top, the lateral margins nearly parallel to each other, and without 

 any distinct depressions: surface rather densely, coarsely punctate 

 toward the top. densely, finely granulose, becoming longitudinally 

 rugose on the occiput, and densely clothed on -the lower half with 

 long, silvery white pubescence, which conceals the surface ; epistoma 

 strongly transverse between the antennae, and broadly but not deeply, 

 arcuately emarginate in front; antennae extending nearly to pos- 

 terior angles of pronotum, serrate from the fourth joint, and all 

 joints longer than wide; eyes large, strongly oblong, and slightly 

 more broadly rounded above than beneath. 



Pronotum about one-fifth wider than long, base and apex about 

 equal in width, and widest along apical half; sides nearly parallel 

 from apical angles to just behind the middle, then obliquely nar- 

 rowed to the posterior angles, which are rectangular: when viewed 

 from the side the marginal and submarginal carinae are feebly sinu- 

 ate, narrowly separated anteriorly, and connected to each other near 

 the posterior angles; anterior margin strongly sinuate, with the 

 median lobe broadly, strongly rounded; base transversely bisinuate, 

 with the median lobe scarcely produced, and arcuately emarginate in 

 front of scutellum; disk moderately convex, with two round, feeble 

 depressions arranged longitudinally at the middle, a rather broad, 

 oblique depression along the lateral margins near middle, and with 

 distinct, short, straight prehumeral carinae; surface coarsely, trans- 

 versely rugose, and with numerous fine punctures between the rugae. 

 Scutellum strongly, transversely carinate. and the surface obsoletely 

 reticulate. 



Elytra slightly wider than pronotum at base, slightly wider at 

 base than behind the middle, broadly, feebly constricted in front 

 of middle, and arcuately narrowed posteriorly to the tips, which are 

 separately broadly rounded, and strongly serrulate; sides of abdomen 

 scarcely exposed above: disk slightly flattened, sutural margins 

 strongly elevated posteriorly, with broad, moderately deep basal 

 depressions, and with an obsolete longitudinal costa on each side; 

 surface densely imbricate-punctate.
