THECLA ONTARIO. 1—2. 
Thecln Ontario , Edwards, Trans. Am. Ent. Soc. ii, p. 209, 1869. 
Male. Expands 1.1 inch. 
Upper side dark brown, color of T. Acadica ; on costal margin of primaries a 
large smooth oval spot ; secondaries have a single tail and a very slight projection 
at extremity of second median nervule ; from the base of the tail a faint white line 
extends along the margin to anal angle ; at this angle a few scales of fulvous ; be- 
tween the first and second median nervules an indistinct marginal dark spot above 
which are a few fulvous scales in crescent form ; tail black, tipped with white ; fringe 
of both wings fuscous, next before the tail white, beyond it, black at extremity, 
white next the margin. 
Under side uniform light brown, color of T. Calanus, Westw. ( falacer of Godart 
and Harris); across the disk of primaries a nearly straight, narrow band of dark 
spots, slightly edged without by white ; this hand is continuous except that the two 
spots in the second and third median interspaces are somewhat lunulate and separa- 
ted ; parallel to the margin is a second hand of faint spots, of dark brown, nearly 
obsolete at each extremity ; on the inner edge of the three or four middle and most 
distinct of these spots are a few white scales. 
Secondaries have a discal row of spots like those of primaries, hut separated, 
forming a nearly straight line (the two middle spots only being outside the line) 
from the costa to a point just above the black space that surmounts the blue patch, 
then turning towards abdominal margin in a zigzag course forming the letter W, 
the last limb of which is long and reaches the extreme margin ; hind margin edged 
by a fine whitish line and bordered by a row of spots occupying the interspaces, 
each of which is edged above with a curved black line on which is a second bluish- 
white line ; the four spots next apex almost obsolete, merely showing a darker 
tinge than the ground color, and on these the black crescents are not distinct and 
the white line is represented by a few scales only ; the fifth spot a shade darker than 
the preceding and edged above with a narrow patch of orange-red ; the sixth 
black with a broad red arch between it and the black line ; beyond the tail a large 
patch of blue scales on a black ground which it does not wholly cover, leaving 
above the blue a small black spot on which are a few red scales ; at the angle a 
rounded black spot narrowly edged above with white, between which and the black 
and white lines, which here are not crescent, is a red space. 
Body above fuscous ; beneath, abdomen ashy-brown, thorax blue-grey ; legs
