would seem very probable that the species has more than a single 

 breed at the southern point of its distribution. 



Remarks. — This species has no synonymy, but it has been mis- 

 identified on several occasions, chiefly on account of the uncer- 

 tainty attached to the name hivittata, and the efforts of authors 

 to follow Scudder's differential features for the species of the genus. 

 Smith reported it as hivittata,*° and again as vigilans,^^ in the latter 

 determination following Rehn and Hebard, who had referred 

 Floridian material of the present species to vigilans.*'^ By the 

 proper reference of the latter to the synonymy under alacris, and 

 a corrected conception of hivittata, we are able to clear up the 

 uncertainty surrounding these names. In the Scudder Collection 

 we find one male and two females bearing the same data as the 

 type material of intertexta, and arranged under hivittata, which 

 are clearly intertexta. From this material we have evidence of 

 the extent to which Scudder's failure to recognize individual varia- 

 tion in this genus led him into serious difficulties. By dogmatically 

 assuming the exact degree of fastigial angulation to be a specific 

 criterion, he associated very different forms and disassociated 

 material of the same species.
