beak-like, pointed, rounded on the under side, less so on the dorsal 

 side ; mesonotum rounded and rising to a low carina ; abdomen coni- 

 cal ; color yellow -green, the abdomen more yellow than elsewhere and 

 granulated with pale yellow; along the side of abdomen a bright yellow 

 band, through which runs a red or an ochrey line ; on ventral side a 

 line of small ferruginous spots ; on middle of wing-case a blackish dot, 

 and a series of marginal dots, one in each interspace. One chrysalis, 

 instead of the ventral lines of spots, had a continuous reddish band 

 which crossed three segments. Duration of this stage nine to ele\-en 

 days. Duration of the larval stages about eighteen days ; of the entire 

 period from laying of egg to imago about thirty-one days. 



Colias Harfordii was described in Proc. Cal. Acad. N. Sci., Feb'y. 

 1 87 7, from seven males taken in southern California, the female not 

 mentioned; and omitting here and there an unimportant word or line, 

 thus: Bright lemon-yellow. Primaries with the border moderate in 

 width, equal throughout its entire length, and more or less serrate on 

 its inner edge. The band is divided by the nervures, but never to its 

 extreme edge. Discal spot oblong, yellow, surrounded by black. 

 Secondaries\vith the border narrower. Beneath, uniform pale orange, 

 a little palest on internal margin of primaries, a>id devoid of the black 

 and grayish scales so apparent in Gccidentalis and Chrysomelas. Discal 

 spot of primaries as on upper side ; that of secondaries clear white in 

 a brown-pink ring ; and there is a faint indication of a row of sub- 

 marginal spots of brown-pink on both wings. 



C. Barbara is described in same paper from two females, "the 

 male unknown:" Whole surface light canary-yellow, with a black 

 cloud at base, and a few scattered black scales along the costa. The 

 marginal band of primaries is composed of black atoms, through 

 which the yellow of the ground color is distinctly seen. // is broadest 

 at the apex, thence narroivs slightly, and continues of equal width to the 

 inner angle. In this respect it differs greatly from Laurentina, {=In- 

 terior), in which the band is apical only, and obsolete before reaching 

 the inner margin. The discal spot is small, ovate, deep yellow, m a 

 black ring. Secondaries are destitute of any border. The discal spot 

 is circular, pale orange, surmounted by a small spot of same color. 

 Under side of primaries pale lemon-yellow, powdered along the mar- 

 gin with black atoms, more broadly so at the apical and costal edges. 

 Discal spot with the yellow centre very plainly marked. Secondaries 

 more closely and thickly powdered with black atoms, giving a green- 

 ish appearance to the surface, and with a dark rose-pink streak at base. 

 Discal spot large, circular, clear white, surmounted by a smaller one, 

 each in brown ring. 



In the Proc. Cal. Acad., for June, 1878, Mr. Edwards says that he is 

 inclined to think Barbara is the female of Harfordii.
