THECLA. 33 



A species closely allied to T. Uncus (Fabr.), but differing constantly in having no 

 black margin to the submarginal rufous band of the secondaries beneath, and in the 

 two discal bands of those wings being further apart. 



The types of T. togarna were from Venezuela, whence we also have examples ; 

 these agree with our Central-American series. In the latter country it is a very 

 common species as far north as the forests of Eastern Guatemala. 



In the Cauca valley of Colombia the male has the black discal spot of the primaries 

 confluent with the black margin, and this character is also seen in examples from 

 Ecuador. 



Hewitson seems hardly to have appreciated the differences between T. togarna and 

 T. Uncus, for he figures one of the former as a variety of the latter 4 . He places too 

 much reliance on the black discal spot of the primaries being cut by the white second 

 median branch, which is a very variable feature. The rufous submarginal band of 

 the secondaries being bordered as in T. Uncus with black, is a much more trustworthy 

 character, and may be relied on as distinctive of the two insects. We have figured a 

 male from Panima.
