In this var. the antennae, palpi, legs and underside (except the 

 middle of the breast, which is picescent) are entirely testaceous.

 by the less fine puncturation of the elytra. The only variation I 

 notice in numerous specimens is in the distinctness of the elytral 

 markings which in some are scarcely traceable.

 difference between it and heat a, Newm., apart from the markings 

 of the elytra. They consist of a large roundish blotch near the
