 Elongate, rather slender, subcylindrical. Black or 



dark brown ; elytra marked with yellow pubescence as follows : a narrow 

 stripe extending from scutellum along the suture to middle, thence curving 

 and angulate to outer margin, a short crossbar near humerus, a subapical 

 band and an apical curved line ; these markings often broken into dots.

One specimen in Webster collection labelled "Ind." Its range 

 is given as the entire United States. Var. f use us Kirby has the 

 sides of thorax covered with pubescent blotches and the elytral

 in the State, while two others perhaps occur.
