Genus Debis

‘After Scudder.) 
margin of the fore wing is either rounded or slightly excavated. 
The palpi are long and narrow, thickly clothed with hairs below; 
the antennae are moderately long, gradually 
thickening toward the tip, without a well- 
marked club; the fore legs in both sexes greatly 
atrophied. 
Egg. —Flattened spheroidal, broadly trun¬ 
cated at the base, the surface smooth. 
Caterpillar. —Body long, slender, tapering 
from the middle; the head cleft, each half being 
produced upward as a conical horn; the anal 
segment provided with a pair of horns similar 
to those of the head, produced longitudinally 
backward. 
Chrysalis.- —Strongly convex dorsally, con¬ 
cave ventrally, with a stout tubercular eminence on the thorax, 
without any other projecting tubercles or eminences; light green 
in color. 
This genus is large, and is well represented in Asia and the 
Indo-Malayan region. I cannot see any good ground for gener- 
ically separating the two species found in North America from their 
congeners of Asiatic countries, as has been done by some writers.

1 6 , larva; Plate IV, Fig. 6 , chrysalis (The Pearly Eye). 
Butterfly.—The butterfly, the male of which is well depicted 
as to its upper side on the plate, does not differ greatly in the 
sexes. The hind wings on the under side are marked with a 
series of beautiful ocelli. In the North the insect is single- 
brooded; in the region of West Virginia and southward it is 
double-brooded. Expanse, 1.75-2.00 inches. 
Early Stages. —The illustrations give a good idea of the ma¬ 
ture larva and the chrysalis. The caterpillar, like most of the 
Satyrince, feeds upon grasses. 
The range of this pretty insect is extensive, it being found 
from Maine to the Gulf of Mexico, and westward to the Rocky 
Mountains.

Butterfly. —Easily distinguished from the preceding species by 
the elongated patches of dark raised scales upon the fore wings,
