They all agree in being colored straw yellow, or very pale vermilion, 

 and being thickly covered with triangular black spots, which are con- 

 nected in C. fasciata. 



Secondaries with one or two transverse rows of three or four large 

 black spots. The genus is distinguished from Eucharia Hiibner, its 

 nearest ally, by its nearly simple anteuna3 and more slender thorax : 

 and from Eujn-epia by its much smaller and narrower wings, the outer 

 margin of which are less oblique in Callarctia. 



Callarctia ornata n. sp. 



S . Very pale salmon ; sides of the front, central dot of the protho- 

 racic scales, patagia and middle of the mesonotum black. Primaries 

 with two long broad black streaks ; the one between the costal and 

 median nervures; the other divided by the internal nervure. Two 

 transverse spots beyond. Between this last and the submarginal row 

 of three spots is a long narrow triangular spot reaching from the costa 

 to the 4th m. nervule. The costal spot of the submai'ginal line is ob- 

 long, the two lower ones triangular. A triangular apical and median 

 spot, the latter twice divided by the m. nervules. 



Secondaries deep salmon color, with two rows of marginal round 

 black spots; an apical and median sub-linear spot. Beneath, both 

 wings are uniformly yellowish salmon, otherwise much as on the upper 

 side. Abdomen with dorsal, ventral and sub-ventral rows of partially 

 united black spots. 



Length, .75. Exp. wings, 1.85 inch.
