White or yellowish, elytra always with three black spots, one at 

 base of inner apical cell, one midway along costa and the third and 

 largest margined with red and situated just outside of clavus not 

 quite half way to its apex. Vertex, pronotum and scutellum each 

 often with a large red spot. Length 3 mm.

Whitish, vertex, pronotum and scutellum with two red longitudi- 

 nal lines. Elytra with three oblique red stripes extending toward 

 inner margin. Length 3 mm. 



With its varieties this species occurs on grapes and is taken in 

 practically all sweepings from shrubs and trees in woodland. It 

 hibernates as an adult under leaves or bark in sheltered places and 

 can be found on warm days in winter and early spring coming out 

 of these shelters.
