ing the elytra darker, with the yellowish pubescent bands connected on sides

Southern half of State ; frequent. ]May 24-.July 29. One of our 

 most handsome species. The spots which are enclosed by the bands 

 of yellowish pubescence vary much in size and shaj^e. The thorax 

 varies in hue as in pvbescens, and a large series will doubtless show 

 that the two are the same, and are connected by the hcbraica of 

 LeC'onte which Smith has placed as a synonym of pube^icens.
