A number of color varieties of this andbimaculata have been 

 named, and the two species probably merge. Among the varieties 

 are my op* I laid., having the head yellow, the sutural black stripe of 

 elytra and black spot before scutellum of thorax wanting, and fla- 

 Ilald., black, with legs yellow and thorax almost wholly black.
