ANTHOCARIS I. 
more and differently marked with green. The yellow form is also wholly wanting 
in Reakirtii. In a letter from Mr. Henry Edwards dated September, 1869, he 
says. — “This species is one of the earliest insects of our spring, and may be seen 
even so soon as March if the season he favorable. As far as my own observation 
goes it is found generally in oak groves, flying about flowers, and is but rarely seen 
in open pastures ; liking shade and flying rapidly from flower to flower. It rarely 
alights, and is difficult to take on the wing, I have met with it chiefly in the 
neighborhood of San Francisco, As to Sara, I first met with it two years ago in 
Santa Clara Co., and was at once struck by its larger size, the yellow color of most 
of the females, and the absence of the irrorated line along the anterior margin, as 
well as by the much fainter green markings on the under side of lower wings. 
Unlike Reakirtii, this species seems to prefer the open fields, flies much more slow- 
ly, and alights often upon flowers of Brassicse, Nasturtium, Ac. I am so accusto- 
med to the two forms that I can now distinguish them by the flight alone. Sara 
appears early in May, or probably in the warmer parts of the State as soon as Ap- 
ril, and continues on the wing until August. Probably at least one-half the fe- 
males are more or less tinged with yellow.” 
ANTHOCARIS COOPERII. 5—8. 
Anthocaris Cooperii , Behr, Trans. Am. Ent. Soc., 1869. Angelina , Boisduval, Lep. de la Cal’e., 
1869. 
Male. Expands 1.4 inch. 
Upper side soiled white with a yellow tinge, much irrorated with black at base 
of wings ; primaries have a small pale orange sub-apical patch, as in female Reak- 
irtii, edged at apex by spots of greenish-black, partly united into a band ; on the 
arc a narrow, nearly straight blackish bar, not quite reaching the costa ; fringes 
white, the nervules on primaries largely and on secondaries slightly tipped with 
black. 
Under side of primaries white ; the orange patch repeated, but paler ; apex 
tinged with green and, as well as costa, somewhat irrorated with greenish-black ; 
discal spot nearly obsolete. 
Secondaries much covered by yellow-green patches, most dense next base. 
Body above grey, beneath, thorax covered by yellow hairs ; palpi white tip- 
ped with grey. 
Female. Expands 1.5 inch. Same color as male; the orange patch want- 
ing, but the nervules within the space orange ; apical spots separated and less dis- 
tinct. Under side of primaries have the apex decidedly greenish-yellow; in oth- 
er respects like the male.
