The broad light yellow stripe more or less straight on lower mar- 

 gin of pronotum extending from front angles nearly two thirds dis- 

 tance to the apex, separates this from all other species. The color is 

 chestnut brown in females becoming darker in males. The pronotum 

 of male is marked with a transverse apical band of light. 



This, like most of the other species in this group has a wide dis- 

 tribution, occurring throughout the entire United States east of 

 Rocky Mountains. It has been found on oak (Qiicrcus sp.) and wild 

 indigo (Baptisia sp.).
