From our region I have only seen one specimen, a female, kindly communicated by 
Dr. Staudinger. This agrees perfectly with others before me from Colombia and 
Ecuador, whence we have a good series of examples. The South-American specimens 
show very slight variation in colour, but the Colombian ones are a little paler than 
those from Ecuador.

I have seen two specimens of this species from Chiriqui. It is very closely allied 
to 4. onustaria, but is larger, and has the lines on the primaries straighter.

This species is common in Guatemala and the State of Panama. It varies very 
considerably in colour and in the distinctness of the markings. Guatemalan specimens 
are always paler in colour than those from more southern localities. Geyer gives? 
Java as the locality of his specimen, but that must be a mistake, the genus being 
entirely confined to the New World. The Mexican specimen in Mr. Schaus’s collection 
is smaller, and has the secondaries less angular than usual; but in our large series from 
Guatemala we have two or three examples very similar to it. 
4, Aischropteryx marciana, sp.n. (Tab. XLII. fig. 2.) 
Male. Primaries and secondaries pale greyish-brown, the primaries with very faint brown streaks over the 
greater part of the surface, a black dot at the end of the cell of both wings; the primaries crossed from
