surface of hindwing of female variable, located between Rs and 

 anal veins (fig. 10) on two examples, but extending from apex to Cui 

 on another example. Ventral surface of hindwing of female yellowish 

 orange with a dark median costal mark. Length of forewing: male, 

 13 to 14 mm.; female, 14 to 15 mm. 



Male genitalia distinctive (fig. 31), clasper of left valve long and 

 slender, exceeding apex of valve; clasper of right valve reduced, less 

 than one-third length of valve. Female genitalia (fig. 32) with the 

 sclerotized fold and groove on the right side of ductus bursae; ductus 

 seminalis from right side of bursa copulatrix; right side of posterior 

 margin of seventh abdominal sternite forming a short, broad lobe, 

 the shape and size somewhat variable. 



Type: Type male, Tucuman, Ai-gentina, E,. Schreiter (USNM 

 64641); 5 males and 1 female paratypes, same place and collector; 1 

 male and 1 female paratypes, same place, P. Girard in the U.S. 

 National Museum, Washington, D.C. Two males and 1 female 

 paratypes, Tucuman, Argentina, P. Kohler, in the personal collection 

 of Mr. Kohler, Buenos Aires, Argentina. 



Distribution : Known only from the type locality. 



Remarks: The sinuous line formed by the basal parts of the 

 ocellate spots of the forewmg, the long clasper of the left valve of the 

 male genitalia, and the sclerotized groove of the right side of the 

 ductus bursae of the female genitalia will enable the entomologist to 

 separate this species and E. paraguayensis (Draudt) from the other 

 species of the splendens complex. The obsolescence of the median 

 part of the oblique subterminal bar on either or both surfaces of the 

 forewing, the yellowish-orange hindwing of the male, the absence of 

 dark apical marks on the ventral surface of the hindwing of the female, 

 and the reduced clasper of the right valve of the male genitalia dis- 

 tinguish examples of robertae from paraguayensis. I name this species 

 with affection after my wife, Roberta.
