Genus Grapta 
and when the first warm winds of spring begin to blow, it may 
be found at the sap-pans in the sugar-camps, sipping the sweets 
which drip from the wounded trunks of the maples. It ranges 
all over the United States, except the Pacific coast, and is com¬ 
mon throughout Canada and Nova Scotia.

form harrisi, Edwards, Fig. 4, $ ; Plate III, Fig. 38, larva; Plate 
IV, Figs. 27, 29, 30, 39, 46-48, chrysalis (The Comma' Butterfly). 
Butterfly .—Dimorphic, in the form dryas with the hind wings 
heavily suffused with black, in the form harrisi predominantly 
fulvous. Expanse, 1.75-2.00 inches. 
The caterpillars feed upon the Urticacece , and are very com¬ 
mon upon the nettle. They vary greatly in color, some being 
almost snow-white. This species is found throughout Canada 
and the adjacent provinces, and ranges south to the Carolinas and 
Texas and over the Northwestern States.

under side; form marsyas, Edwards, Plate XIX, Fig. 14, $ ; Fig. 
15, $, under side ; Plate III. Fig. 33, larva; Plate IV, Figs. 41, 
42, chrysalis (The Satyr). 
Butterfly. —The species is so accurately depicted in the plates 
that a description is hardly necessary. The form marsyas is 
smaller, brighter, and with the dark spots on the upper side of 
the hind wings reduced in size. Expanse, 1.75-2.00 inches. 
The food-plant of the caterpillar is the nettle. It occurs occa¬ 
sionally in Ontario, and thence ranges west, being not uncommon 
from Colorado to California and Oregon. 
(4) Grapta hylas, Edwards, Plate XIX, Fig. 7, 6 ; Fig. 8, $, 
under side (The Colorado Angle-wing). 
Butterfly. —The butterfly closely resembles G. silenus on the 
upper side, but may easily be distinguished by the uniform pale 
purplish-gray of the lower side of the wings. Expanse, 2.00 inches. 
The early stages are unknown. The insect has thus far been 
found only in Colorado, but no doubt occurs in other States of 
the Rocky Mountain region.

$ , under side; Plate III, Fig. 32, larva; Plate IV, Figs. 31, 33-35, 
chrysalis (The Faun). 
Butterfly.—This species is readily recognized by the deep 
indentations of the hind wings, the heavy black border, and the
