rows of black triangular spots crossing them. The row of spots near 
the outer margin is tipped externally with yellowish-brown, while 
the other spots are outlined with gray. There are several clear white 
spots distributed on the wings, as shown in the illustration. The lower 
wings are brown with two rows of faint yellowish-brown spots near 
their outer margins. The body is blackish-brown. The larva feeds 
on willow and poplar. 
Pholisora catullus. 
A much smaller species related to the foregoing is Pholisora 
catullus. In this insect the wings and body are black, or very dark 
blackish-brown, and the wings are unadorned, save with a line of 
small white spots near the apex of the fore wings. The head and 
palpi also have a few small white dots. This little butterfly is dis¬ 
tributed over the whole United States. 
In the genus Pamphila is assembled a large number of species 
(over one hundred being inhabitants of the United States) of small, 
stout-bodied butterflies, distributed over the whole continent, and 
often very abundant in point of number. The antennae usually end 
in a club with a pointed recurved tip. In coloring they are gener- 
alty dark brown with spots or markings of yellow or yellowish-brown. 
The sexes are generally separated without difficulty by the males 
having a strongly marked oblique brown stripe on the forward wings. 
These insects abound in the fields and meadows, being particularly 
plentiful along flowing streams where the sweets of various kinds of 
wild flowers tempt them to remain. In walking through the rank 
grasses and weeds beside a brook or pond, one may find dozens of 
them in June, July and August, and a large number of species may 
be taken in such localities. A good many will be ruined in the net, 
however, as they move their wings so rapidly when captured that 
often only the torn fragments of them remain when taken out. 
When disturbed they fly rapidly with a jerking motion, and again 
alight after moving but a few feet. A good many of them fall a
