more and differently marked with green. The yellow form is also wholly wanting 

 in Eeakirfii. In a letter from Mr. Henry Edwards dated September, 18(39, 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 be favorable. As far as my own observation 

 goes it is found generally in oak groves, flying about flowers, and is but rarely seen 

 in oi)en j^astures ; 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 flxinter green markings on the under side of lower wungs. 

 Unlike ReakiiiU, this species seems to prefer the open fields, flies much more slow- 

 ly, and alights often upon flowers of Brassicoe, Kasturtium, &c. 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 COOPEEII. 5—8. 



Antliocaris Cooperii, 13ehr, Traus. Am. Eut. Sue, 1869. Angelina, Boisduval, Lep. de la Cal'e., 

 1809. 



Male. Expands 1.4 inch. 



Upper side soiled white with a yellow tinge, much irrorated with black at base 

 of Avings ; primaries have a small pale orange sub-apical patch, as in female Beak- 

 irtii, edged at aj)ex by spots of greeni.sh-l»lack, partly united into a band ; on the 

 arc a narrow, nearly straight blackish bar, not quite reaching the costa ; fringes 

 white, the nervules on jirimaries largely and on secondaries slightly tijsped with 

 black. 



Under side of primaries white ; the orange jiatch repeated, but j^aler ; 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 s2)ots sejxirated and less dis- 

 tinct. Under side of primaries have the apex decidedly greenish-yellow ; in oth- 

 er re.spects like the male.
