the body, black, paler at base, the third and fourth joints equal; 

 prothorax nearly a third wider than long, parallel, with evenly 

 rounded and finely reflexed sides, the angles broadly rounded; base 

 as wide as the apex, arcuate laterally; surface obscure aeneous, 

 green laterally, having transverse rugulae, obsolete impressions and 

 fine, somewhat abbreviated stria; foveas short, discal, linear and 

 deeply impressed, smooth; elytra oblong, one-half longer than 

 wide, not quite one-half wider than the prothorax, the feebly 

 arcuate sides more rounded at base; apex gradually obtusely 

 rounded, with feeble sinus; outer green area half the width, the 

 marginal bead bright cupreous; stride moderate, closely punctulate; 

 intervals flat; foveae of the third occupying the entire width of the 

 interval; ninth stria very close to the margin; anterior male tarsi 

 moderately dilated. Length (cf 9 ) 7.5-7-8 mm.; width 2.8-3.0 

 mm. Montreal to North Carolina, also Indiana. Not uncommon 

 in certain localities octopunctatum Fabr. 



Dorsal punctures six or seven; body larger, moderately convex, shining, 

 with dark cupreous lustre; under surface and legs black; head 

 nearly three-fourths as wide as the prothorax, with rather prominent 

 and well developed eyes, the impressions very small, feeble; palpi 

 black, the last joint scarcely as long as the third; antennas black, 

 not quite half as long as the body, the third and fourth joints equal; 

 prothorax a third wider than long, parallel, with evenly arcuate 

 and finely reflexed sides throughout, the angles extremely obtuse and 

 broadl}' obliterated, except a minute prominence at the setigerous 

 pore; base arcuate laterallj^ as wide as the moderately sinuate apex, 

 the apical angles with slightly blunt tips; surface with some feeble 

 transverse rugulae, the impressions obsolete, the stria fine, subentire; 

 foveae short, linear, discal and deeply impressed, distant from the 

 sides, having a very few indistinct punctures; elytra one-half 

 longer than wide, less than one-half wider than the prothorax, 

 parallel, the moderately arcuate sides more rounded at base; apex 

 gradually rounded, with feeble sinus; surface micro-reticulate and 

 alutaceous (9), more polished (cf); striae fine, smooth, grooved; 

 intervals flat; foveae of the third all on or near the third stria as a 

 rule; met-episterna about twice as long as wide; anterior male 

 tarsi distinctly though not widely dilated, with smooth upper surface. 

 Length (cf 9) 8.3-9.0 mm.; width 3.3-3.7 mm. California 

 (southern coastal regions), — Dunn. Nine specimens.
