BUTTERFLIES HERRERA AND FIELD 491 



Veins on hinchving dii'tj" wliite outlined on both sides by gray with a 

 white spot over the lower discocelhilar vein and adjacent area. Dif- 

 fering chiefly from T. m. microdice in having these gray stripes along 

 the veins usually more narrow and with tlie white spot over lower 

 discocelhilar vein smaller and in the smaller wing expanse. 



Length of forewing, 20-30 mm. (average, 22.2 mm.). 



Female: Plate 4, figure 12a. Head with scales behind eyes and 

 with outer face of palpus pale yellow. Wings quite different from 

 those of the male, having the ground color above dark yellov/ and with 

 dark brown stripes along veins. Other dark markings dark brown 

 in color and more extensive than in the male. Ground color of wings 

 below darker yellow than in the male with base and disc of forewing 

 on this surface yellowish white rather than pure white and with a 

 series of large but faint submarginal sagittate markings on this wing 

 extending to below vein Cuo. White spot on lower discoeellular vein 

 of hindwing small (as in the male) and with orange along costal margin 

 of hindwing below more distinct than in the male. In addition there 

 is a faint streak of orange below cell and another below vein Cu2. 

 T. in. fiieguensis differs from the other subspecies, in the female sex 

 particularly, in the ground color of the wings above and on the base 

 and disc of the forewing below. In addition it differs from T. m. 

 macrodice and T. in. arctodice in the color of the scales behind the 

 eyes and of outer face of palpus. As is true of the males, the females 

 have the smallest wing expanse of any of the other subspecies. 



Length of forewing, 20-22 mm. (average 2L3 mm.). 



Type locality: Puerto Harberton, Territory of Tierra del Fuego, 

 Argentina.
