12 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 119 



Length of forewing 11-13 mm. 



Female genitalia, as illustrated by figure 25, not separable from 

 janeirica. Ductus bursae usually sharply curved immediately before 

 ductus seminalis. Figures 24 and 24a of janeirica and figure 25 of 

 chacona were not included to show differences between these two 

 species. Both species have ductus bursae Uke figures 24a and 25 and, 

 although I have not seen chacona like that of figure 24, 1 do not doubt 

 that it occurs. 



Type-locality. — ''Formosa, Argentina." 



Additional type data. — This species was originally described 

 from a series of several specimens (=syntypes), the exact number not 

 being stated. These syntypes are presumably in the Jorgensen 

 collection in the Museo Argentino de Ciencias Naturales, Buenos 

 Aires; however, a lectotype cannot be designated at the present time 

 because I have been unable to obtain anj^ information concerning these 

 syntypes. My identification is based upon the original description, 

 upon a topotype specimen and upon this being the southernmost 

 species in the genus. 



Distribution. — This species is found in the state of Parana in 

 Brazil west and south through Paraguay to the provinces of Salta, 

 Cordoba and Buenos Aires in Argentina.

Figures 6, 20/, 26, 57-60 



Male (figs. 57-58). — Differing from bactra and related species in 

 having the brilHant blue on hindwings above restricted to lower half 

 of wing below cell. Anal lobe without red spot or at most with only 

 a few red scales. Forewing below similar to janeirica, differing from 

 that species on the hindwing in having a second submarginal black 

 pupillated red spot, this spot in interspace Mg and smaller than 

 similar spot in interspace Cui. 



Length of forewing 10.5-12.5 mm. 



Male genitalia, as illustrated by figure 6, with lateral lobe of uncus 

 having distal margin concave, with lower margin straight or nearly 

 so and with upper distal angle produced, forming a short finger-like
