 Pontia simplonia, Freyer, Beitr. Schmett. ii. pi. Ixxiii. fig. 2 (1829). 



Rapids of the Drowned, 29th 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.

Of MOTHS twenty-two species were obtained, of which one 

 is a Sphingid, four are Noctuse, and the remainder Geometrse ;
