A shadow of uncertainty must remain in regard to the correct 

 identification of the males of rufinoda Cresson and those of closely- 

 related species (until some worker can find a positive method of 

 separating these and other difficult males) for the following reasons: 

 (1) After extended studies, the writer has so far found no satisfactory 

 characters to separate the males of rufinoda Cresson from the males of 

 echo Mickel or other unknown, closely related species. (2) The 

 species rufinoda Cresson was described from a male taken in an area 

 (Colorado) where the females of both echo Mickel and the female long 

 accepted as, but not proven to be, the female of rufinoda Cresson have 

 been recorded in numerous localities. (3) Finally, two other closely 

 related species, irene Banks and argia Mickel, of which the males are 

 inseparable without association with the females, also are recorded 

 from Colorado although less commonly. All of the above females are 

 readily separated. 



Type. — The type male of C. rufinoda Cresson, from the Rocky 

 Mountains, Colorado Territory (Riding), is in the Philadelphia 

 Academy of Natural Sciences, no. 1955.
