nus).—In the Northeastern United States the most common 
of the hair-streaks is this species (Fig. 466). The upper 
surface of the wings is dark brown or blackish brown. The 
under surface is blackish slate-brown nearly as dark as the 
upper surface, and marked as shown in the figure. 
The larva feeds on oak and hickory. Excepting the 
southern portion of the Gulf States, the species is found 
throughout our territory east of the Rocky Mountains, and 
in the southern part of Canada. 
The Olive Hair-streak, Mitoura damon (Mi-tou'ra 
da'mon).—The upper surface of the wings is dark brown, 
with the disk more or less deeply suffused with brassy yellow 
in the male or tawny in the female; the hind wing has two 
tails, one much longer than the other, both black tipped 
with white. The lower surface of the hind wings is deep 
green; both fore and hind wings are marked with white bars 
bordered with brown (Plate VI, Fig. 6). 
The larva feeds on red cedar. The species occurs from 
Massachusetts to Florida and westward to Dakota and 
Texas. 
The Banded Elfin, Incisalia niphon (In-ci-sa'li-a ni'phon). 
—In the butterflies of the genus hicisalia the fringe of the 
outer margin of the hind wings is slightly prolonged at the 
end of each vein, giving the wings a scalloped outline; 
they also lack tail-like prolongations of the hind wings. 
There are several species occurring on both sides of the con¬ 
tinent. One of these, the Banded Elfin, is represented on 
Plate VI (Fig. 4). In this species there is a distinct white 
or whitish edging near the base of the under side of the 
hind wing which limits a darker band that occupies the 
outer two thirds of the basal half of the wing. 
This species occurs in the Eastern and Middle States. 
The larva feeds on pine. 
The Hair-streaks described above are of moderate size 
and modest colors. The two following will serve to illustrate 
a somewhat different type. 
The Great Purple Hair-streak, Atlides halesiis (At'li-des
