Edwards Butterflies of X. Am. Part 8, (1871.) 



Female. Expanse 2 inches. 



Antennse black, tliroax black with white hairs ; abdomen blackisii above near the tliorax, 

 rest white. 



Upper surface white, primaries, costji edged with black rather broadly till to the discal 

 vein on which it is continued to its extremity; a black border with inner edge sinuous, 

 broader at apex and diminishing to a mere line at inner angle, extends from costa downwards, 

 within this border are six irregular white spots, the one nearest the inner angle being much 

 the smallest. 



Secondaries have an irregular sub-marginal black line, from which to the exterior margin 

 the veins arc edged with black, which Midens at their tips, forming as it were .six large white 

 s[iot,s, from the space between tlie veins and sub-marginal line and exterior margin. 



Under surface white, primaries nearly the same as above, spots in border a little larger. 

 Secondaries, veins all margined with brownish black ; sub-marginal band as above ; costa and 

 interior margin edged with rose or flesh color ; a row of marginal lunulate spots and a line 

 of same color running parallel with and adjoining the inside of the sub-median nervure. 



This species, of which I am not aware any figure of the female has heretofore been pub- 

 lished, has had almost as rough a time of it as had Colias Eurydice ; it is evident, that until 

 very lately, the tcmale was entirely unknown to Lepidopterists in this country ; Mr. W. H. 

 Edwards, in his Butterflies of N. Aiuerica, part 8, gives three excellent representations, all 

 males, although one of them he supposed was a female, and described it as such in the accom- 

 panying text. Scudder, in the Proc. Boston Soc. Nat. History, 1861, where he redcscribed it 

 under the name of Pieris Tau, gives elaborate descriptions of both sexes, of which he says: "a 

 large number of specimens are in the Museum of Comparative Zoology obtained by Mr. 

 Agassiz at Gulf of Georgia ;" now it is evident from the description that either all of the 

 specimens above alluded to were males, or else Mr. Scudder gave them a \-ery careless examina- 

 tion, indeed, for the only difference he mentions between the sexes is that on the upper surface 

 of secondaries the female " repeats slightly at the outer angle, the markings of the lower sur- 

 face ;" then, after stating that " it rejiresents in AVashington Territory the P. Sisimbrii Boisd. 

 of California," (which it does not resemble a bit, either in size, shape or markings,) he goes on 

 to say that the way he distinguishes between males and females in his foregoing description 

 was founded on the "cut of the hind margin of secondaries ;" lie then goes on and gives some
