Variations. — This species is rather constant in size and coloration 

 but quite variable in some of the other characters. Some examples 

 are considerably more robust than others, the pronotum is from one- 

 third to one-half wider than long, the sides are either nearly parallel 

 to each other from the apical angles to basal third or regularly, 

 strongly rounded, and the median depressions are more or less vari- 

 able in depth. The pubescent design on the elytra may consist of an 

 arcuate vitta extending from the basal depression to middle, and a 

 broad, oblique fascia at apical fourth, or the vitta may be interrupted 

 so as to form three or four small spots. 



Host. — The larval habits are unknown, but the adults have been 

 collected by H. A. Wenzel on the foliage of poison ivy {Toxicoden- 

 dron radicans (Linnaeus) Kuntze), and the numbers taken indicate 

 that poison ivy is probably the host plant.
