Argynnis Bremnerii. 6. Argynnis Eurynome. 7. Argynnis Meadii. 8. Grapta Hylas. 9. Satyrus Charon. 5. Argynnis inornata. | 10. Erebia Meadii. Colias Astrsea, n. sp. Male. — Expands 2 inches. Upper side pale ochraceous, very little tinted with orange on disks of secondaries from cell to marginal bor-der and from base to hind margin of secondaries below cell, this color being not decided but only a tint ; border of primaries pale black, of medium width, erose within, very little advanced on costa and send-ing out a short and attenuated spur on inner margin ; border of second-aries very narrow, erose within, and unusually long, exteuding from above upper sub costal nervule to below lower median ; discal spot of primaries a short black streak ; on secondaries wanting. Under side of primaries yellow nearly as above, without orange ; of secondaries yellow densely covered with black scales so as to obscure the whole surface ; discal spot of primaries very narrow, black, enclos-ing a few yellow scales, of secondaries white, as in Alexandra, without a ring; no spot on costal margin ; a scarcely perceptible pink tint at base; legs yellow, the tibia and tarsi faint pink; palpi yellow tipped with pink. (Antennae wanting in the specimen described.) From a single male taken near the Yellowstone Lake by the Hayden Expedition, in 1871. On the under side this species is nearest Alexan-dra; on the upper of a different shade of color from any of our species. Anthocaris Julia, n. sp. Male. — Expands 1.3 inch. Upper side pure white, black at base; primaries have a bright orange apical patch, edged outwardly by a sharply serrated black band which is broadest at apex and narrow as it descends the margin, but is not broken into distinct spots as in the allied species Sara&ud Reakirtii ; on the arc a sinuous black bar nearly pro-tracted to costal edge, and at its upper extremity expanded in direction of base to double its width elsewhere ; from the lower third of hind margin proceeds a stripe of scattered black scales which borders the orange patch,
