BUTTERFLIES — HERRERA AND FIELD 493 



Male: Plate 4, figure 13. Head with scales behind eyes and with 

 outer face of palpus yellow to orange. Wings above somewhat as in 

 typical microdice but with all darlc markings much larger and with a 

 series of dark wedge-shaped markings at end of veins. Usually with 

 a series of submarginal intervenal dark markings on the hindwing. 

 Wings below with ground color of hindwing and of apex of forewing 

 darker yellow than in T. microdice fiieguensis or T. microdice microdice 

 and with the costal margin of hindwing darker orange than in those 

 subspecies. Hind^ving below with a distinct submarginal series of 

 sagittate intervenal markings, and, as is true of T. m. microdice, there 

 is a large white spot over the lower discocellular vein. This sub- 

 species differs from T. m. microdice and from T. m.. Jueguensis also in 

 having the series of dark submarginal sagittate markings on the 

 underside of forewing very much larger and extending below vein Cu^ 



Length of fore\ving, 22-28 mm. (average, 25.2 mm.). 



Female: Plate 4, figure 13a. Head with scales behind eyes orange 

 and with outer face of palpus yellow to orange. Wings above similar 

 to female T. m. microdice except that the dark markings are much more 

 extensive and the veins on the hindwing are entirely dark brown or 

 occasionally with small streaks of white but never white throughout 

 their enth^e length. Wings below with ground color darker j^ellow 

 than in the males and with orange along costal margin of hindwing 

 darker. Similar to undersurface of female T. m. microdice, with veins 

 on hindwings more of a silvery white with yellow ground color deeper 

 and with dark markings of forewing larger, more distinct. Most 

 similar to T. m. arctodice but with a distinct series of fuscous, sub- 

 marginal sagittate markings and with white stripes on veins narrow, 

 usually covering only the veins.
