NOTES ON PIERIS AND ANTHOCHARIS. 



BY HARRISON G. DYAR, NEW YORK. 



After reading Mr. J. W. Tutt's note on page 47 of Can, Ent., I have 

 looked over many of our species of Pieris and Anthocharis with the fol- 

 lowing result : — Our genus Pieris is probably entirely pure and congeneric 

 with the European. The majority of our species of Anthocharis are con- 

 generic with Eiichloc cardamines, as figured by Mr. Tutt, but some species 

 are different and should be removed from the genus. I have not ex- 

 amined seven of the species given in Prof. Smith's list, but those which 

 I have seen separate in synoptic form as follows : — Mr. Tutt's nomencla- 

 ture of the veins differs from that in use here, as will be seen by a com- 

 parison of my figures (Figures 9 and 10) of Anthocharis sara with the 

 figures on page 47 of Can. Ent.
