Venation: As illustrated (fig. 55). 



Legs: With paronychium, claw, and pulvillus as illustrated (fig. 69). 



Male: Plate 1, figure 1. Head with an orange margin behind eyes 

 and with outer face of palpus white to pale yellow. Wings white above, 

 usually with apex of forewing, costal margin and distal portions of 

 radial veins dark fuscous in color. Extreme bases of both wings above 

 irrorated with dark fuscous scales, especially along base of cubitus in 

 the hindwing. Hindwing and apex of forewing below white with a 

 faint yellowish cast, remainder of forewing white. There is a faint 

 orange spot in extreme base of hindwing below and many specimens 

 have the veins on this surface faintly outlined with fuscous, especially 

 along the base of cubitus. 



Length of forewing, 23-28 mm. (average 25.5 mm.). 



Male genitalia as illustrated (figs. 27, 41). No differences were 

 found between the genitalia of typical T. maenacte and its subspecies 

 T. maenacte itatiayae. The genitalia of four males were studied. 



Female: Plate 1, figure la. Head as in the male. Wings above 

 white with veins heavily outlined with fuscous and with dark apical 

 area of forewing more extensive than in the male. Wings below as in 

 the male, with ground color more yellow and with fuscous along the 

 veins more distinct. 



Length of forewing, 23-28 mm. (average, 25.5 mm.). 



Female genitaha as illustrated (fig. 83), with anterior lobe of inner 

 genital plate large, subtriangular, and having its ventral margin 

 triundulate. As in the male, no differences were observed between 

 the two subspecies. The genitalia of six females were studied. 



Type locality: "Paraguay, Republique Argentina" = Paraguay. 



Location of type: British Museum (Natural History), 



Additional type data: Described from a number of male speci- 

 mens (number not specifically stated) in the Boisduval collection. Of 

 these, only a single specimen is in the British Museum (Natural His- 

 tory), and we consider this to be the holotype.
