s 



Southern half of State; frequent. May 24-July 20. One of our 

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

 of yellowish pubescence vary much in size and shape. The thorax 

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

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

 LeConte which Smith has placed as a synonym of pubesceii*.
