 apical thirds of elytra bluish-black ; thorax, a broad median band of elytra 

 and joints two to six inclusive of antennae, reddish-yellow ; beneath as in 

 angustata. Length 6-7.5 mm.

 regarded as a variety of angustata. but in my opinion specifically 

 distinct. Occurs especially on the foliage of the wild lettuce, Lac- 

 iuca canadensis L., but often found on flowers of buttercup (Ra- 

 nunculus).

 finer ones on intervals. Length 10.5 mm.
