and from the costal edge, a line connecting them being at right 

 angles to the costal edge, or sloping slightly towards the basal hind 

 edge of the wing. These two dots are sometimes of equal size, some- 

 times the one nearest the costa has twice the diameter of the other, 

 and occasionally vice versa ; and in two or three specimens, there is 

 a dusky cloud on their terminal side. At about one-seventh of the dis- 

 tance from the apex to the base commences a narrow and obscurely- 

 defined fuscous band, slowly and gradually diverging from the ter- 

 minal margin for three-fourths its length, when it suddenly converges 

 with the terminal margin for the remaining one-fourth of its length, 

 forming an angle of about 140° with its former course, and attains the 

 interior margin. On the terminal side of this band, the ground-color 

 of the wing is of a paler yellow, and generally with a faint, purplish 

 tinge. Hind wings lake-red, except the sub-costa and the terminal one- 

 third or one-fourth, or occasionally the terminal one-fifth. Beneath, the 

 front wings have the same sub-terminal narrow band as above, but less 

 distinctly angulated, and except towards its costal extremity, not fus- 

 cous, but dull lake-red. On the basal side of this band the sub-costa is 

 bright ochre-yellow, with a few dusky dots, and the other part lake- 

 red, shading off gradually to a pale, dull yellow with a tint of pur- 

 ple as the band is approached, which last color is continued beyond 

 the band, where there are also a few scattei-ing dusky dots. In a 

 single S the lake-red color extends nearly to the terminal edge. The 

 hind wings are ochrey-whitish, sprinkled with dusky dots, especially 

 along the costa ; two-thirds of the way along their costa from the base 

 there is a very obscure, narrow band, dusky towards the costa, else- 

 where brown, gradually and slowly diverging from the terminal edge 

 for three-fourths its length, and then angulated as in the front wing 

 till it attains the interior or anal edge. 



The ? differs only as follows : — In one specimen, the front wing 

 above is almost ochrey-brown. In two, the white dots of the front 

 wing are entirely absent ; and in another, only the one next the costa 

 is present, and is smaller than usual. The ground-color of the front 

 wing is always the same on both sides the band. In one specimen, 

 the lake-red color of the hind wing extends to its terminal margin. 

 Beneath, the band on the hind wings is always very distinct, and wider 

 than in S .

 That there may be no possible doubt as to the ? antenna being bi- 

 pectinate, it may be as well to state that on June 22 a 5 and ? copu- 

 lated in the cage, and remained in copulation for half an hour after 

 they had been pinned. The first imago, a ? , appeared June 13, and 

 the last, also a ? , July 28, all without exception coming out about 

 dusk.
