Genus Grapta 
which are mimicked by other species among the butterflies and 
moths of the region which they frequent. A naturalist familiar 
with the characteristics of the butterfly fauna of South America 
can at a glance determine whether a collection placed before him 
is from that country or not, merely by his knowledge of the 
peculiar coloration which is characteristic of the lepidoptera of 
the region. The most brilliant butterflies of the neotropical 
fauna are the Morphos, glorious insects, the under side of their 
wings marked with eye-like spots, the upper side resplendent in 
varying tints of iridescent blue. 
In the Nearctic Region there is a remarkable development of 
the genera Argynnis , Melitcea , and Phyciodes. There are also a 
great many species of the Satyrince and of the Hesperiidce , or 
“skippers.” The genus Colias is also well represented. The 
Nearctic Region extends southwardly into northern Mexico, at 
high elevations, and is even continued along the chain of the 
Andes, and there are species which are found in the vicinity of 
San Francisco which occur in Chili and Patagonia. In fact, when 
we get to the southern extremity both of Africa and of South 
America we find certain genera characteristic of the north tem¬ 
perate zone, or closely allied to them, well represented. 
Genus GRAPTA, Kirby 
(The Angle-Wings) 
Butterfly. —Medium-sized or small, characterized by the more 
or less deeply excavated inner and outer margins of the fore wings, 
the tail-like projection of the hind wings at the ex¬ 
tremity of the third median nervule, the closed cell 
of the same wings, and the thick squamation of 
the palpi on the under side, while on the sides 
and tops of the palpi there are but few scales. 
They are tawny on the upper side, spotted and 
bordered with black; on the under side mimick¬ 
ing the bark of trees and dead leaves, often with 
a ^-shaped silvery spot on the hind wings. The 
insects hibernate in the butterfly form in hollow 
trees and other hiding-places.
