THECLA 1. 
Secondaries have a long discal streak, a curved transverse row of black spots 
and streaks, each surrounded or edged by white, the six from costa nearly round, 
the fifth being anterior to the general line, the seventh long and bent towards anal 
angle, the last a streak running up the margin and bent near its inner extremity ; 
hind margin edged with whitish and bordered by a vermillion (sometimes orange) 
band which is divided by the nervures into spots, each of which is arched above 
and edged with black on which rests a line of bluish white ; this band extends 
some distance up the abdominal margin and encloses, on hind margin near anal an- 
gle, a large rounded space sprinkled with blue atoms ; the three or four red spots 
next outer angle partly obsolete and the spot next the blue patch sometimes edged 
on the marginal side by black ; in some specimens a black edge at anal angle. 
Body above dark brown, below greyish- white ; legs greyish- white ; palpi white, 
at extremity black tipped with white ; antennae black annulated with white ; club 
black, reddish at tip. 
Female. Same size. Similar to the male, only wanting the oval spot on pri- 
maries. 
Taken in Canada, near London, and in various parts of New England and 
New York. 
I have received from Mr. Saunders a description of the larva and chrysalis 
of this species as follows : 
“ Found feeding on willow, June 11, 1865, June 18, 1866, and about middle 
of June 1867 and 1868. Length 0.63 inch ; onisciform. Head very small, pale 
brown and shining, drawn within the second segment when at rest. Body above 
green, of a moderately dark shade, thickly covered with very short whitish hairs, 
scarcely visible without a magnifier. Body thickest from third to tenth segments ; 
a dorsal line of a darker shade of green than the rest of body. Dorsal region flat, 
rather wide and bordered with a raised whitish-yellow line, beginning at the third 
segment and growing fainter on twelfth and thirteenth. Sides of body inclined at 
an almost acute angle and striped with faint oblique lines of greenish-yellow. A 
whitish-yellow line borders the under surface beginning at the anterior edge of sec- 
ond segment, and extending entirely around the body to a point opposite the place 
of beginning ; this line is raised in the same manner as that bordering the dorsal 
ridge. Twelfth and thirteenth segments much flattened. Under surface similar 
to upper, with the same coating of short fine hairs ; feet and prolegs partake of the 
general color. In a younger specimen the head was almost black with a streak of 
white across the mandibles. The under side was rather deeper in color than upper, 
with a faint bluish tint. 
“Chrysalis 0.32 inch long; greatest width 0.15 inch; thickly covered with 
minute hairs. Color pale brown with many dots and patches of a darker shade ;
