This geographic race can be distinguished from typical fasciatus 

 solely by the proportions of the caudal femur and ovipositor; over its 

 entire range there is an increase in the robustness of the caudal femur 

 and in the female a decrease in the length of the ovipositor, which, when 

 compared in length with the caudal femur, is found to be as short as 

 or shorter than that member. So few exceptions are to be found to 

 this that, in spite of the close affinity of these southern individuals 

 to fasciatus in all other respects, they should certainly be considered 

 to belong to a definite geographic race. 



Type: 9 ; Georgia. [Scudder Collection.] 



Description of Type. — Agrees perfectly with typical fasciatus, 

 except that the caudal femora are proportionately longer and heavier 

 and the ovipositor shorter, in consequence the length of the caudal 

 femur is equal to that of the ovipositor. 



Males from the same State as the type do not differ from males of 

 fasciatus except in their more robust caudal femora, and so great is 

 the size variation in the species that, with no other than this differen-
