Venation: As illustrated (fig. 57). 



Legs: With paronychium, daw, and pulvillus as illustrated 

 (fig. 71). 



Male: Plate 2, figures 7, 7b. Head with palpi white on the sides; 

 scales behind eyes orange, darker above than below. Wings with 

 markings dark brown to black in color. Ground color on upper sur- 

 faces and on disc and base of forewing below white. Below on hind- 

 wing and apex of forewing very pale yellow or white washed with 

 yellow. Hindwing below with costal margin and extreme base orange 

 and with a white spot over the lower discocellular vein and adjacent 

 area. T. autodice differs from blanchardii chiefly by having the hindwing 

 above entirely without markings or, if marked, with very faint spots 

 at the ends of veins only and by usually having the black bar at end 

 of cell, isolated from the costal margin. 



Length of forewing, 20-30 mm. (average, 26.1 mm.). 



Male genitalia as illustrated (figs. 28, 43) . Very close to blanchardii, 

 differing chiefly in having the aedeagus slightly less sinuate. The 

 genitalia of seven males were studied. 



Female: Plate 2, figure 7a. Head as in the male. Wings with 

 markings dark brown to black. Ground color on upper surfaces 

 white, sometimes pale yellowish on hindwing. Wings below colored as 

 in the male. This sex difl^ers from the male chiefly in having all dark 

 markings on upper surfaces larger and more distinct. From females 

 of blanchardii it differs in having wedge-shaped m-arks on apex of 

 forewing above extending inward onlj^ to the submarginal black spots 

 and also in having the ground color of this surface of the hindwing 

 white, sometimes with a famt yellowish tinge but not distinctly yellow 

 as in that species.
