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,
