BUTTERFLIES OF MAINE. 65 
is a large olive patch, extending on segments seven to ten to 
the external tip of the prolegs. A pair of black transversely 
arranged dorsal dots in the suture behind segment three, and 
a more or less obvious lateral one just above and behind the 
sixth and eighth pair of stigmata surrounding the lateral 
white line. Segments four to eight and ten to twelve, with 
more or less shining, elevated, blue dots. On segment three, 
a pair of prickly, cylindrical, black horns, transversely ar- 
ranged, and .16 of an inch long. On segments four, eleven 
and twelve, a pair of large dorsal tubercles transversely 
arranged, each crowned by a little bunch of from eight to 
twelve robust prickles. On segment six, a pair of similar 
tubercles, but still larger, of a yellowish color. On segments 
five, seven, eight and ten, tubercles similar to those on seg- 
ments four, eleven and twelve, but smaller. On segment 
thirteen, four black, prickly, dorsal horns, quadrangularly 
arranged, and each about .03 of an inch long. Stigmata and 
legs, blackish. Different examples vary greatly in the general 
depth of coloring, and in the proportion of the lighter and 
darker shades. 
The pupa, (Fig. 23, 6,) is similar in form to that of L. az- 
themis, and is marked with burnt-umber brown, ashy-gray, 
flesh-color and silvery white. 
The winter is passed in a hibernaculum (Fig. 28, ¢ and d), 
composed of a leaf, similar to LZ. arthemis. 
The eggs of this species are destroyed by spiders, ants 
and a minute egg parasite belonging to the Hymenopterous 
family, Chalcidide, and the larve, while small, are destroyed 
by spiders, a Tachina fly, a species of Microgaster and birds. 
This species flies in Orono, from the middle of July to the 
middle of August.
