Length 13 to 18 mm., greatest width 7.5 to 11 mm. 



Color of dorsum usually bright shining green. Occasional speci- 

 mens may be entirely light blue, others rarely entirely purple black. 

 Ventrally specimens are generally black with slight bluish iridescence, 

 particularly on the femora. Antenna dark reddish brown with 

 antennal club light reddish brown. Eye canthus, clypeus, and 

 anterior two-thirds of vertex coarsely, closely punctured. The tips of 

 the three tubercles on the head, one medially near the basal margin of 

 the clypeus and one beside each eye, lack punctures. A distinctly 

 indented narrow line runs from the middle of the vertex forward to 

 the posterior edge of the clypeus, where it bifurcates and runs along 

 the posterior margin of the clypeus, finally reaching the outer margin 

 at the juncture of the clypeus with the eye canthus. Clypeus mar- 

 gined, almost semicircular. Poorly margined eye canthus forms a 

 very obtuse angle with clypeal edge, with sides of eye canthi slightly 

 arcuate, almost parellel. Pronotum completely margined, moderately 

 convex with the lateral edges evenly arcuate. Width of anterior half
