BUTTERFLIES — HERRERA AND FIELD 505 



homoeodice, the discocellular bar being represented by a narrow line. 

 As in inversa and homoeodice, this species differs from saglttata and 

 stigmadice in lacking all black markings on hindwing. Wings below 

 very similar to homoeodice and inversa with yellow of ground color and 

 black bordering along veins even paler than in those two species and 

 differing from both in having the upper half of hindwing cell orange. 



Length of forewing, 22-29 mm. (average, 25.4 mm.). 



Male genitalia as illustrated (figs. 36, 49). Aedeagus in lateral 

 view similar to inversa, being thicker thi'oughout and differing also 

 in having a broader and deeper distal incision on its left side. The 

 genitalia of six males were studied. 



Female: Plate 6, figure 20a. Head as in the male with outer sur- 

 faces of palpi orange and thus differing from all other females in 

 Group D. Scales behind eyes orange. Forewing above white, some- 

 times slightly creamy, with dark brown markings on fore wings, as 

 illustrated, being much more extensive than in the male but much 

 less so than in the female of inversa, the discocellular bar and sub- 

 marginal row of spots being greatly reduced. Hindwing above with 

 ground color white, sometimes slightly cream colored with veins white 

 and bordered by pale brown. Wings below quite like the male, 

 difi'ering from inversa in having yellow of ground color paler, and like 

 stigmadice in having upper half of cell orange. It differs from stigma- 

 dice in lacking the distinct dark brown stripes along the veins especially 

 on the base and disc of forewing and in lacking the clearly defined 

 orange lines between the veins on the hindwing and on apex of 

 forewing. 



Length of forewing, 21.5-26 mm. (average, 24.3 mm.). 



Female genitalia as illustrated (fig. 89), with anterior lobe of inner 

 genital plate subtriangular and with both the posterior and the 

 ventral margin of this plate serrate. Ductus bursae with the ribbon- 

 like plate on ventral surface opposite the opening of ductus seminalis 

 divided and with a semicrescentic plate just anterior to this. The 

 genitalia of four females were studied. 



Type locality: "Cotana," Department of La Paz, Bolivia. 



Additional type data: Described from five males, cotypes 

 (locality as given above, 1,200-2,200 m., December). 



Location op types: In the Zoologisches Museum der Humboldt- 

 Universitat, Berlin. According to Dr. E. M. Hering of that institu- 

 tion, there are only two males remaining in the collection. A tliird 

 male was destroyed during World War II. Two males are unaccounted 

 for. A lectotype is not designated. 



Method of identification : By a study of one of the two remaining 

 cotj^pes and by comparison with the excellent original colored figure 

 and description.
