ure—but it was not until the present season that the maples were in- 
fested to such an extent as to injure and disfigure them. 
Just as the leaves were beginning to put forth, close observation re- 
vealed the fact that they were all more or less stippled with transparent 
spots, some mere dots, others a tenth of an inch or more in diameter, 
As the leaves expanded the delicate cuticle of the upper surface would 
give way and they presented the appearance of being perforated with 
holes and much torn and tattered along the margin, marring their 
beauty for the entire season. If, about the 1st of May, the leaves were 
carefully examined, there would be found on the under surface of each 
{rom two or three to a dozen or more very delicate bugs of a very pale 
translucent green color, the embryo wing-pads being almost white. 
They were further characterized by very long and slender legs, beak 
and antenne, body flat and broad oval in outline; head small, eyes rel- 
atively large, oblong and bright red-brown in color. The larvz varied 
in size from one-twentieth to one-eighth inch in length, and so far as I 
could discover there were but two larval molts. Scattered about over 
the leaves were small, round, translucent green eggs rather larger than 
a Portulaca seed. The pupal form was precisely like the larval, except 
in point of size and relative development of the wing-pads. When the 
under side of a leaf was turned up for examination the bugs, large and 
small, would dart, on their hair like legs, to the reversed surface, mov- 
ing with the greatest rapidity and sometimes dropping to the ground 
in their evident desire to escape observation. The final transformation 
occurred about the middle of May, after which the companies dispersed. 
The species is a pretty one, although, from the glassy texture of the en- 
tire hemelytra and the general delicacy of coloring, it always has a 
somewhat immature appearance. 
This bug happily lacks the disagreeable odor so common to the species 
of this suborder and which pertains even to most of its closest allies. 
Absence from Kirkwood after the middle of May somewhat inter- 
rupted my observations on this insect. On my return, early in June, 
margins covered with dark brown; corium usually with a transverse, dark-brown 
are next the posterior border; cuneus long and wide, the incised base fuscous, and the 
inner margin brown; membrane pale testaceous, with two or more dark clouded spots, 
the inner submargin of the principal arcole, a spot at its tip and the base next the 
cuneus all more or less fuscous. Venter pale greenish. 
Length of body, female, 5™™; to tip of wing covers, 7™™; width of pronotum, 2™™. 
Male, length of body, 4™™; to tip of wing covers, 53™™; width of pronotum, 12™™, 
This has proved to be a very common insect in various localities. 
Mr. Cassino collected numerous specimens around Peabody, Mass. Mr. Bolter sent. 
to me a pair from [linois and Missouri; and I have taken it from Alders, Maples, and 
many other kinds of small trees and shrubs on Cape Ann, Mass., also near the base of 
the White Mountains, and in New Hampshire, and near Quebec, Canada. 
Mr. Forbes has also forwarded to me specimens from near Normal, Ill. 
It resembles Lygus invitus Say, and presents several of the color varieties common to 
that species; butit isa much larger insect, of a longer figure, and has a more flattened 
upper surface.—P. R. UHLER.
