 Pontia simplo7iia, Frejer, Beitr. Schmett. ii. pi. Ixxiii. fig. 2 (1829). 



Rapids of the Drowned, 29tli June. 



A second example of this species was in the " Zeller " 

 collection from Colorado labelled Anth. lanceolata. We have 

 no authenticated E. lanceolata, Boisd., in our collection ; but 

 the species so labelled is identical with E. simplonia. From 

 E. ausonides, to which it is closely allied, it differs chiefly in 

 its inferior size and the smaller and narrower white markings 

 on under surface of secondaries.
