87. J.<>(hiit<t ii* ciiHreus Packard. 
The caterpillar of this. species has been found by Professor Riley 
feeding on the maple, and closely resembling the caterpillar of L. olivata, 
Packard. The type of my original description was captured by 
myself in Brunswick, Me. ; Professor Riley's was bred in Washington, 
D. 0., the moth appearing May 28. Mr. Howard L. Clark has found it 
not uncommonly in Rhode Island. My original type was from Maine. 
Moth. — Male ami female : Antenna well pectinated on the basal two-thirds, filiform 
at the end ; the body and wings greenish ash, the wings green, olive sea-green in 
tint. Head greenish on top, ashen in front; palpi ashen, black on the sides. Thorax 
ashen, greenish on the sides at the insertion of the wings; on front edge of the thorax 
a dark brown transverse stripe ; a more distinct transverse stripe behind, and the 
hinder edges of the teguke dusky; between the two oblique tegular stripes the 
hinder part of the thorax is dark brown, including a small tuft on the hinder 
edge of the thorax and a large two-lobed flattened tuft which covers the base of 
the abdomen, the posterior edges of the double tuft becoming blackish. Fort- 
wings rather short and broad, the apex less produced than in L. olivatus ; the wing 
unusually free from scalloped bands; two unequal scallops at the insertion of the 
wing (obsolete in the male before me) ; middle double-scalloped line well marked 
in the female (obsolete in the male in front of the median vein) ; the scallops 
uneven, two in median space, the largest one rectangular; a short acute scallop 
in front of the median vein and extended outward along it; two nearly even- 
sized scallops on the costal edge; a clean space between the middle and outer 
scalloped lines; outer scalloped line very irregular, scallops deep and heavy black- 
brown, and the line curving deeply inward from the median vein to near the apex on 
the costa. The costal edge on outer third, with three distinct narrow linear black 
spots ; the venules marked with black and whitish-gray scales (in the male this 
outer line is almost obsolete). A submarginal row of eight blackish spots, three of 
which are situated behind the last median venule; this series is plainly dislocated, 
the subapical three being set farther inward than those below, and this is a ready 
means of separating the species from L. olivatus. In these females the fore-wings and 
thorax are yellowish green, while in the male of a clear sea-green. Hind wings 
dusky ashen, yellowish on the costa, on the outer third of which is the beginning of 
an outer whitish line, forming two scallops; the wing is pale, almost whitish at base, 
but dusky toward and at the margin. Beneath, the fore-wings are clear ash, the 
costa a little dusky, with fine blackish linear marks toward the apex; the sub- 
marginal row of blackish spots appear through, but the series is not dislocated; 
hind-wings not marked, except by three submarginal dusky spots behind the second 
mediau venule ; abdomen ash, with a faint yellow-green tint ; length of body, male. 
20 to 21 mm ', female, 23 mm . Expanse of wings, male, 45 mm ; female, 55 mni (2.10 inches). 
This species may be known by the less pointed fore-wings, quite 
square in the male, by the clear space between the middle and outer 
scalloped lines, aud by the dislocated series of submarginal dusky 
spots; the wings in the male are uniformly sea-green, while in the 
female the tint is yellowish green. My original description in third 
vol. Proc. Ent. Soc. Philadelphia, is defective, as the type specimen 
was rubbed, and without the greenish tint of fresh specimens. From 
L. olivatus it is distinguished by being more uniformly and darker 
green and by the lack of whitish patches. The discal spot is almost 
obsolete, and with only a slightly marked dusky patch beneath, this 
blackish patch being large and conspicuous iu L. olivatus.
