MAPLE BUGS. 421 
©yes relatively large, oblong, and bright red-brown in color. The larvae varied in 
size from one-twentieth to one-eighth inch iu 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 iu point of size and relative development of the 
wing-pads. When the under side of the leaf was turned up for examination the 
bugs, large aud small, would dart on their hair-like legs to the reversed surface, 
moving 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 entire 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 Kirk wood after the middle of May somewhat interrupted my obser- 
vations on this insect. Ou my return, early in June, only a few of the mature bugs 
remained among the curled and torn leaves on which they had developed. Occa- 
sionally throughout the summer a specimen would.be met with, as often on the foliage 
of any other tree as on maple, but there was no second brood. This species, unlike 
Capsus oblineatus, is never to my knowledge found on flowers. It probably secretes 
itself early in the season, and becomes dormant until the following spring. 
The only remedial applications experimented with were Pyrethrum powder and air- 
slacked lime, both of which were measurably effective, judging by the small scale 
on which they were tried. 
Mr. P. R. Uhler gives the following description of this insect: 
Lygus monachus n. sp. — Long-oval, pale green or testaceous, coarsely punctate 
above, sericeous pubescent. Face convex, highly polished, bald ; base of vertex with 
a longitudinal impressed line, towards which a similar line runs obliquely each side 
from the inner corner of the eyes ; antennae sparsely and minutely pubescent, basal 
joint thickest, a little longer than the head, tapering at base, second joint thrice as 
long as the basal, infuscated and a little enlarged towards the tip, third and fourth 
setaceous, together not as long as the second. Pronotum highly polished, convex, 
coarsely punctate in transverse wavy lines, each side with a dark brown vitta or 
long spot ; lateral margin smooth, callous at base, the humeral angles subacute, cal- 
losities prominent, convex, almost confluent on the middle ; lateral flap of pronotum 
irregularly punctate. Pectoral pieces pale, impunctate. Legs pale green, feebly 
pubescent ; apex of posterior femur usually with one or two fuscous bands, tip of 
tarsi and the nails black. Scutellum moderately convex, excavated at base, trans- 
versely obsolete-punctate, more or less infuscated. Corium coarsely, transversely 
rostrate-punctate, the clavers more or less infuscated, sometimes with all but the 
margins covered with dark brown ; corium usually with a transverse, dark-brown 
arc 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 areole, a spot at its tip, and the base next the 
cuneus all more or less fuscous. Venter pale greenish. Length of body, female, 
5 mm ; to tip of wing-covers, 7 mra ; width of pronotum 2 mm . 
Male.— Length of body, 4 mm ; to tip of wing-covers, 5£ mm ; width of pronotum, 
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 Illinois and Missouri, and I have taken it from alders, maples, 
and many other kinds of small trees and shrubs on Cape Ann, Massachusetts, 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, 111.
