Wings beautiful yellow ; primaries, with the summit, very sharp, 

 sometimes a little falcate. 



Primaries blackish at the base, a large black point in the 

 middle ; a wide black border, sinuate, or rather emarginate inte- 

 riorly, making the yellow part bear a rude resemblance to a dog's 

 head, of which the black point forms the eye. On the upper edge, 

 near the summit, are three whitish oblong streaks. Fringe rosy. 



Secondaries with a black border strongly dentated within ; two 

 large geminate discoidal orange spots, and some streaks of the 

 same color near the border. Fringe yellow, washed with rosy. 



Under side of the primaries dull yellow, except in the middle ; 

 a black eye with a silvery pupil. 



Under side of secondaries deep yellow, with two silvery, dis- 

 coidal, geminate points, circled with ferruginous ; besides this, a 

 transverse line of ferruginous points, as in most of the species. 



Body blackish above ; yellowish below ; antennas reddish. 



The female is of yellow, less bright; the border of the primaries 

 is of black, less deep, with some indistinct yellow streaks ; the 

 border of the secondaries is interrupted, and the surface here and 

 there presents some traces of rosy. Expands two inches and a 

 half. 



Larva green, with a lateral white band, punctured with yellow; 

 besides this band, there is on each segment a transverse black 

 band, bordered with yellow. Feeds on different species of Trifo- 

 lium.
