rudimentary and the third spine of joint 2 is lacking. Body elongated, 
sides subparallel, rounded toward the anterior end, joint 13 produced 
into a slender pointed tail. Skin covered with large, irregular, conic 
not contiguous, clear granules. Depressed spaces (1) to (8) present, 
small, ill defined, but devoid of the coarse granules. Color very 
whitish green, opaque; a white line along the subdorsal ridge with 
upper dark green, clear border. The centers of the depressed spaces are 
also whitish, but obscured in the general white shading; (1) and (4) 
have green centers, but not contrasting. A fainter white line along 
lateral ridge and subventral edge. The larva is whiter than the backs 
of the leaves on which it rests, a condition necessary to offset the dark 
shade which its thickness produces when looked at from beneath. The 
larva stands about on the same level as A. y-inversa in degree of speciali¬ 
zation, exceeding it in the presence of the tail-like modification and 
slightly more reduced sette of stage I, but falling behind in coloration. 
Affinities, Habits, etc. 
This species belongs to the group of which Apoda biguttata is typical, 
the palaearctic smooth Eucleids. It departs a little from this type as 
noted above, but not in important characters. Its nearest ally is the 
other species of the genus, P. elegans. The moths emerge unusually 
early in the season, at the same time as Tortricidia testacea , at or be¬ 
fore the middle of June. The females rest quietly and do not fly at 
all till after pairing, even though several nights intervene.* Normally 
emergence from the pupa takes place during the day, the moths pair 
the subsequent night and the eggs are deposited in the next night. 
Flight of the males begins rather late at night, not till after 9:30 
P. M. The eggs are deposited singly on the under side of the 
leaves. The larvae frequent dry woods and bushes on the edges of 
fields. They do not inhabit damp or dark locations. Very often the 
larvae are found on low small plants only a few inches from the ground, 
and they are never high feeders. Larvae occurred not uncommonly at 
Bellport, Long Island, in a dry pine and oak woods on small wild cherry 
bushes which had about six leaves apiece and did not exceed a foot in 
height. 
* Most 9 Eucleids fly on the second night after emergence, and if not mated 
the previous night, refuse the g entirely. Phobetron and Calybia are an exception, 
for they will mate after an infertile flight, but in this case the eggs are without 
vitality, most only proceeding to the first embryonic stages, and those that do hatch 
never live to mature.
