A second example of this species was in the ‘ Zeller” 
collection from Colorado labelled Anth. lanceolata. We have 
no authenticated #. lanceolata, Boisd., in our collection ; but 
the species so labelled is identical with . s¢mplonia. 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.
