There is a fine series of this noble species in the collection, rep- 
resenting two or three possible varieties. In this connection Mr. 
Doherty’s note to the author is worthy of consideration. “In this, 
the Salpinx-Pademma group, the butterflies vary in a surprising 
manner, and that in the same locality. Mr. DeNiceville has shown 
me a large series of Pademmas from Lower Bengal, in which every 
specimen might easily be described as a separate species. This fact 
seems not generally known at home, and so naturalists keep on 
forming species in this group on the same grounds as in Crastia, 
or Calliplcea, which are remarkably constant.”

This is the local Celebesian race of L. Europa , Fabr., and is 
characterized by the larger size and the strongly arched costa of 
the primaries, a phenomenon specially common in Celebesian forms, 
and to which Mr. Wallace most instructively calls attention in his 
work upon the Malay Archipelago, pp. 287-8.

There are a number of specimens in the collection which I can- 
not do otherwise than refer to this widely distributed and variable 
species. They are all, however, darker in color than any spec- 
imens I have from other localities, and the males have the external
