NORTH AMERICAN HESPERID>E. 



BY EUGENE M. AARON. 



No. 1.— ERTCDES URANIA and EUDAMUS HESUS. 



It is the purpose, in this series of short papers, to give descrip- 

 tions of new or little-known species of North American Hes- 

 PERID.E, with notes that will be calculated to aid students in the 

 study of this neglected Family. There are a few species of Hes- 

 PERiD^ which have never been described, the identification of 

 which depend on illustrations only to be found in rare and costly 

 works. Others are inadequately described or, in the opinion of 

 the writer, confounded with older species, and still others are as 

 yet undescribed. Where it seems to be desirable to elucidate the 

 text, plain drawings will be furnished.
