208 NORTH AMERICAN MUTILLIDAE 



characters separate this from hexagona and ruja. To grotei it 

 is much more closely allied. 



This is the most northern species of the group, and one of our 

 most northern Mutillidae. In common with many species of 

 other families, its known range bridges the gap between the 

 northern Rocky Mountains and our eastern mountain regions 

 b}^ way of Canada. The western specimens usually have some- 

 what more greyish pubescence on the thorax than those from the 

 East. All of the specimens before me have the head and thorax 

 black except one from Florida, and that individual is the only 

 record from south of Falls Church, Virginia. 



The identify of Mutilla canadensis of Provancher with briaxus 

 is made clear from his description. Not only is it the only 

 species known from Canada, but Provancher refers to the white 

 brush at the apex of the scape, thereby leaving no doubt of the 

 insect to which he had reference. The name secunda was pro- 

 posed by Dalle Torre to replace canadensis of Provancher. 



There is little doubt of the identity of the males referred to 

 this species by Rohwer. That the female which he also 

 describes belongs to it, seems likewise probable.
