68 BUTTERFLY COLLECTOR'S 



margin black, in which on the inner side are one or two 

 white spots scarcely visible; underneath nearly like the 

 female of C. Eilusa, but yellower. 



Observation. '-Having at length," says Mr. Haworth, 

 " found Rvc perfect specimens of this fine Papilio, in five 

 different cabinets, (all of which were taken in England, and 

 agree exactly with each other in every respect.) I now give 

 it as a distinct species, and not as a variety of Ediisn only, 

 which it has hitherto in this country been conceived to be. 

 And in this I have the happiness to be supported by the 

 elegant work of Hiihner, whose denomination of this species, 

 Helice, I have with due deference preserved ; though previous 

 to the possession of that author's Schmet I had determined 

 it to be distinct, and in my MS. as in the Proi/rotmis called 

 it Eclusa alba."
