 Length 12-14 mm. Anterior prothoracic lobe armed on the disk with long spines. 



Posterior prothoracic lobe unarmed, bigibbous on the disk. Margins of the female 



abdomen prominently undulate. Abdomen of the male varying from almost entire to 



quite prominently undulate. 



Habitat : United States and Canada. Type, Mus. Holm. 



I doubt the synonomy of Thunberg's hispidus as it was described 

 from India. In Gmelin's Edition of Linnaeus' Syst. Nat., I, (4), p. 

 2144, 1788, under the name setosiis, it is said to inhabit America, 

 Australia and India. 



This species, as originally defined, occurred in Central America 

 and Mexico as well as in the United States and Canada. But as re- 

 cently pointed out by Mr. Champion, the form occurring in Central 

 America is not diadema. This being true it may be doubted if dia- 

 dema occurs south of the Mexican border.
