To describe in detail those colours and markings of an 
insect, which the eye can embrace at a single glance on a 
well executed representation, is surely unnecessary. We 
shall therefore merely observe that this species has hitherto 
remained unfigured: that it is a native of Southern Brazil, 
and of such rarity, that in two years, we never met with 
more than one specimen. 
In some observations upon what appear to us the leading 
groups of the Diurnal Lepidoptera, published some time 
ago, we considered those groups wherein the anterior feet 
are perfectly developed, and the chrysalis braced by a 
transverse thread, as the most perfect and typical. Sub- 
sequent observations confirm us in this general view; but 
it still remains to be investigated, to which group the 
generic name of Papilio should be retained. The wide 
dispersion of that form represented in the two European 
species Podalirius and Machaon, and which form occurs in 
all the temperate and tropical regions of the globe, leads us 
to suspect it as the most typical group: to this, Papilio 
Niamus, from its very close affinity to Podalirius, w- 
questionably belongs.
