 variable in coloration and sculpture. Several varieties have 

 been described, some of which are considered as distinct species

by certain writers. The beetle is about i inch in length ; the 

 antennae and legs are reddish or yellowish brown ; the head 

 is reddish, and the thorax brownish. In the typical form the 

 wing-covers are black with two pale yellowish longitudinal 

 stripes. In the light-colored variety, blanda, the thorax and 

 wing-covers are paler and the wing-covers have the pale stripe 

 much broader, often leaving but little of the dark markings. 

 In some specimens the wing-covers are uniformly pale. All 

 gradations occur (Figs. 200 and 201).
