PIERLS MEXAPIA. 15 



minute differences in the shape of the wings, but docs not make any mention whatever of the 

 black mesial line on upper surface, or the very remarkable flesh-colored edging of costa, and 

 six marginal lunules of same color on under surface of secondaries ; so we must come to the 

 conclusion that Scudder fell into the same error as W. H. Edwards, and described both sexes 

 from male specimens only. 



I would suggest whilst on this subject that it might be better ])erhaps, instead of heeding 

 imaginary difFeranccs in the cut of the wings, which only lead to error ; to bear in mind that 

 in none of the Pierida are the male and female marked alike. 



Dr. Felder in the Weiner Monatschrift is more acurate, and appears to be the only one 

 who has heretofore really known the female ; he notices that while the male has but five 

 white spots, in the black apical patch, the female has six and also mentions that on secondaries 

 of female, below, the costa, the basal and other spots are livid. 



For the example from which I made my drawing I am indebted to my valued friend, 

 Mr. Henry Edwards, of California, who i-cccived it from A'ancouver's Island.

NOTES ON SOME SPECIES. 



Papilio Burtonii, Peak., Proc. Acad. Nat. Sc, Phil., p. 8<J, 1868, is a synonym of P. 

 Columbus, Hew., Trans. Ent. Soc, Ser. II, Vol. 1, p. 98, t. 10, f 1, 1850. 



Papilio Caleli, Peak., Proc. Ent. Soc, Phil., II, p. 138, 18G3, is Papilio Polymetus, 

 Godt, Enc. Meth., 1810. 



Eresia Yorita, Peak., Proc. Ent. Soc, Phil., \'., p. 224, 1805, is Ercsia Ezra, Hew., 

 Ex. Butt., Ill, Ercs. t. 4, f 29, 1864. In Kirby's Catalogue, this is set down as variety 

 of Eresia Theona, Men.; on what grounds I do not know, there certainlv is little or no 

 resemblance. 



*Colias Semperi, Reak. is C. Dimera, Doubl., IIcw., Gen. D. L., t. 9, 



f. 3, 1847. Although Reakirt's name might be retained for tlie white female variety, which 

 I believe he was the first to notice and describe. 



Lycffiua Helloides, Boisd., L. Castro, Reak., L. lantlie, Edw., concerning these there 

 is some confusion, either Helloides is unknown in X. American collections or two of the 

 above are synonyms, which latter I am inclined to believe is the real state of affairs, for I do 

 not believe any one American collection can produce examples of all three ; Mr. Edwards 

 has in his I believe Helloides and lanthe ; Mr. Mead has lanthe and Helloides, and I 

 have helloides and Castro, but my Helloides is the same as the lanthe of the others and 

 ray Castro is like their Helloides, a specimen of the typical Helloides from Dr. Boisduval 

 would be of some use here I trow. 



April, 1873. 



''I have in my possession the types of Reakirt's Semperi male and female, hut where he described it 1 cannot 

 recollect or at the moment ascertain.
