brown between the zigzag band and the base; and between 
tlie same band and the margin three black spots, behind the 
middle one of which is a rust-red spot with a black centre. 
The wings expand from to Idj inch. This pretty species 
is found on the mouse-ear (^G-naphalium plantagineum) in 
]\Iay, and on the flowers of the spearmint in August. 
Some kinds of Theda have the hind edo-es of the winors 
O O 
notched, but not tailed. This is the case with the Niphon 
Fig. 107 . butterfly ( Theda Niphon of Hiib- 
iier), (Fig. 107,) which has been 
taken at Sweet Auburn early in 
]May. As in the Auburn butterfly, 
the wings are deep brown above, 
with a large rusty space on each ; 
the notches on their edoies are white, and the teeth between 
them are rounded and of a black color; on the under side 
the wino:s are lio-ht brown, with dark brown wavy and zio-zao- 
lines, two of which are bordered on one side with white. 
The wings expand inch. 
The Mopsus butterfly (^Theda Mopsus of Hiibner) differs 
from all the forecroino; in havino; the hind wino-s entire and 
O O O O 
not tailed; but the inner angle projects a little, as it does in 
some species of Lyccena. In form, and in the color and 
arrangement of the spots on the under side of the wings, 
it approaches to the Phlceas and Americana; but in these 
species the eyes are not downy, and the males have not the 
oval opaque spot near the front margin of the anterior wings. 
The Mopsus butterfly is dark brown above, with a row of 
seven or eight deep orange-colored spots near the margin of 
the hind wings, larger and much more conspicuous on the 
under than on the upper side. The Avings beneath are light 
brown, Avith a roAv of deep orange or A^ermilion-colored spots 
near the hind marmns of all the Aviiifis, an inner and more 
irregular row of small black spots encircled Avith ANdiite on 
the same, and tAvo more similar spots close together on the 
middle of the hind Avings. It expands inch. ^ly only
