This widespread and common species is so well known that 

 little comment is necessary. The fact that the yellow stripes of 

 the elytra are narrower than the black would lead one naturally 

 to describe the elytra as black with yellow vittae; they may, 

 however, with equal or perhaps greater propriety be described as 

 yellow with a sutural and two moderately wide discal vittae and 

 the lateral edge, in part, black.
