AMERICAN LEPIDOPTERA. 369 



Descriptions of new species of DIURNAL LEPIDOPTERA found within the 



United States. 



BY WM. II. EDWARDS. 



Antiiocaris Reakirtii, n. sp. 



Male. Expands 1.3 to 1.5 inch. Upper side soiled white, blackish 

 at base ; primaries have a large bright orange apical patch, as in *S'ara, 

 edged on the apex by black as in that species, with serrated black 

 spots also upon the hind margin ; a narrow, slightly bent bar from 

 costa across the arc where it connects with a brown, curved bar from 

 inner angle; costal edge much specked with black scales ; fringe alter- 

 nate white and black. 



Secondaries have three or four patches of black at tips of upper ner- 

 vules ; fringe white, black at ends of nervules. 



Under side white •; the orange spots reduced and paler ; costa of 

 primaries and the whole space on apex and margin outside the orange, 

 densely covered with green patches ; on the arc a bent bar ; seconda- 

 ries densely and uniformly covered from base to margin by large green 

 patches. 



Female. Expands 1.7 inch. Same color as male; costal margin 

 slightly specked; the orange spots paler and narrower, reaching from 

 costa to hind margin, not edged by black on inner side, but on outer 

 by a sinuous band, between which and the apical border is a white 

 patch ; the band connected with the triangular marginal spots by black 

 nervures; on the arc a tortuous bar, in most cases starting from costal 

 edge ; beneath as in the male, except that costa, margins and secon- 

 daries are much less spotted with green. 



California. From specimens in my own collection and those of 

 Messrs. Reakirt and Henry Edwards, and Dr. Behr. 



This species has been regarded as a form of Sara. Its distinctness 

 was first pointed out to me by Mr. Eeakirt and I have since learned 

 that our Californian lepidopterists had assured themselves of the same 

 thing. 



The males of the two species much resemble each other on the upper 

 side except in size, Sara expanding more by three or four tenths. 

 But on the under side the present species is much more and differently 

 marked with green. The females differ upon the upper side. I am 

 informed by Mr. Edwards that the yellow form is wholly wanting in 

 the smaller species, while of Sara, at least one-half are decidedly 

 yellow.
