of hindwing and differs from these species in having a very strong 

 discocellular black bar on upperside of forewing. Like homoeodice it 

 differs from orthodice in having lateral surface of palpi white to pale 

 yellow not orange. It is easily separated from homoeodice in its lack 

 of orange between the veins and below the cell on the undersurfaces 

 of hindwing and from orthodice in lacking orange in upper half of cell 

 on this wing. 



Length of forewing, 27-28 mm. 



Male genitalia as illustrated (figs. 34, 48), with aedeagus in lateral 

 view having central part relatively more slender than in the other 

 species of Group D and with dorsal and ventral margins of this cen- 

 tral portion more nearly parallel than in the other species of this 

 group except orthodice. From orthodice it differs, in addition to the 

 slenderness, in having a narrower and shorter distal incision on the 

 left side. The genitalia of both of the known males were studied. 



Female: Plate 6, figure 19a. Head with outer surfaces of palpi 

 pale yellow. Scales behind eyes orange. Forewing above white with 

 dark brown markings on forewing as illustrated, being very extensive 

 with an especially large discocellular bar and large submarginal dark 

 band. Hindwing above differing from all other species in Group D 

 in having a clesr yellow ground color. Veins white with dark brown 

 scaling as illustrated. Wmgs below not differing from the male ex- 

 cept with dark brown scaling along veins stronger, with discocellular 

 bar of forewing more distinct and with the submarginal series of 

 sagittate markings on this wing clearly indicated. 



Length of forewing, 27.5 mm. 



Female genitalia as illustrated (fig. 90), with anterior lobe of inner 

 genital plate nearl}'^ subcircular, having a small lobelet at either end 

 of ventral margin. The ribbon-like plate on ventral surface of ductus 

 bursa e is situated opposite and posterior to the opening of the ductus 

 seminalis. Ductus bursae with two large plates, one ventral and one 

 dorsal and anterior to the opening of ductus seminalis. Only a single 

 specimen, the holotype, was available for dissection and study. 



Type locality: "Quebrada Carapunco, Department de Tafi, 

 Provincia de Tucumdn," Argentina. 



Additional type data: Described from a single female, the holo- 

 type (2,500 m., November 1932). 



Locatiox of type: In the collection of the Instituto Miguel Lillo, 

 Tucumdn, Argentina. 



Method of identification: By a study of the holotype. 



Additional remarks: The two known males, although from quite 

 a distant locality, Cuzco, Peru, are here associated with the female 

 holotype because of their great similarity in color and pattern. One 

 of these males has the forewing with outer margin more straight and
