fine black scales; the discal spot of same wing small, white, in a red- 

 brown circlet, about which were scales of same color; no patch at outer 

 angle; no sub-marginal spots in three of the examples, but traces of 

 such spots in the fourth. On the Plate, in But. N. A. Vol I., this fourth 

 male is represented with three points in the three lower interspaces on 

 fore wing, and three in the middle of hind wing. 



The female was wholly pale yellow, without any border; under side 

 thickly dusted, the discal spot as in the male; no patch at outer angle; 

 no sub-marginal spots. 



C. Astraeawas described Trans. A. E. Soc, 1872, from a single male 

 taken in Yellowstone region by the Hayden Expedition. Upper side 

 pale ochraceous, a little orange-tinted on disk of hind wing; border 

 pale black, of medium width. Under side of fore wing yellow, of hind 

 wing so thickly covered with blackish scales as to conceal the whole 

 surface; the discal spot of hind wing small, white, without a ring, and 

 like that oi Alexandra; no patch at outer angle, no sub-marginal spots. 

 Subsequently I received another male, from Yellowstone, agreeing in 

 all these points with the type. So far as I remember, this comprises 

 all that was known of Astrcea up to 1883. 



In the summer of 1883, Mr. Wm. M. Courtis, M. E., then at Judith 

 Mts., Montana, sent me four males, Astrcea. The specimens before 

 received had been much rubbed, and were old and faded before cap- 

 ture. The Mt. Judith males were in fair condition, and the peculiar 

 ochraceous shade was deeper than in the type. This color occupies 

 the same parts of both wings as does the deep orange in Christina. 

 But one of these four showed the entire wing covered with ochraceous, 

 except just at base, where yellow prevailed. The type Astrcra had 

 the discal spot of under hind wing small, white, with no edging. These 

 Judith males all differed from the type here, having a few roseate scales 

 around the white spot, or else a mere thread of roseate. All were im- 

 maculate and thickly dusted. With these males came one other which 

 approached Christina, but the orange was rather a decided tint than a 

 solid color. There came also two males, E, of deep lemon yellow, with 

 orange-ochraceous on the disks of fore wings only, restricted to the 

 median interspaces, which it filled to the marginal borders. Both had 

 the discal spots as in the first mentioned, were thickly dusted and im- 

 maculate. 



No yellow females came from Mt. Judith, but there were two white 

 females, and these at the time much puzzled me, as it did not occur to 

 me that they must be albino Astrcra. These are greenish white; one 

 with a faint broad border reaching quite to inner angle of fore wing, 

 with interior light patches; the other with a slight border on upper half 

 of wing only. Beneath, both are thickly dusted; are without patches 

 at outer angle, and without sub-marginal spots; the discal spot of one is
