t lie first median venule. This band incloses a prominent, large, roundish, black 

 (fiscal <lot, with a faint whitish circle around it, but not nearly so distinct as 

 in the female. A white line, mixed with dark, angular, wavy, and parallel 

 with the outer edge of the median band, and situated half-way between the 

 band and the outer edge of the wing. A fine, wavy, white, submarginal line; 

 a prominent, long, dark, oblique, apical streak, edged above with white. 

 Fringe on both wings with a prominent white line at base. Hind wings 

 dusky within the middle, inclosing the small discal dot; beyond are four or 

 five wavy lines like those on the front wing, with a more prominent one half- 

 way between the dark inner portion and the edge of the wing; beneath, the 

 lines are distinctly reproduced, but not the median band; the costa is check- 

 ered with light and dark spots, and there is a small, black, discal dot. 



Female of the same form and size as the male, but the ground-color is 

 a uniform, bright, clear red. The dark mesial band is consequently indistinct; 

 but the large, conspicuous, broad, white, discal ringlet will easily distinguish 

 this species from any other Larentian moth. The outer line is white, wavy, 

 and irregular, and much more distinct than in the male. The markings on 

 the underside of the wings are much as in the male; but the outer line, 

 common to both wings, is much. darker and more distinct than in the male.
