Var. Elytrorum linea discoidali obsoleta, vitta submarginali 

 latiori et distiuctiori. 



The black velvety pile is almost as dense as in C. siituralis, 

 F., but on the thorax there is a Avell defined metalhc green 

 dorsal line, the flanks and lateral tubercles being also glabrous; 

 and the longitudijial vittte of the elytra are narrow, linear and 

 well defined ; the submarginal vitta is tolerably narrow and well 

 defined from the base to the middle, but it then becomes diffused, 

 and blends with the general faint green or violaceous tinge of 

 the apical portion of the elytra.
