males) are an almost uniform green above, except for the five dor- 
sal black spots. 
LIFE HISTORY. 
The life history of this species cannot yet be given in all its de- 
tails, but the essential facts are well enough known. The adults, 
with a very few pupe intermingled, pass the winter under rubbish 
and matted vegetation, in a variety of situations, no preference 
being shown for one kind over another. They are consequently 
found in the woods among the dead leaves, under boards, in grass, 
under the broad leaves of mullein, and in general wherever a suit- 
abie shelter against the winter weather offers. 
With the earliest warm days of spring they venture forth, and 
collect upon whatever tender springing vegetation of tree or shrub 
offers them a supply of sap within the reach of their rather slender 
beaks. On their food plants they lay their eggs; although the pre- 
cise time when they commence this operation bas not yet been made 
out, nor indeed, has the egg itself ever been seen. The young soon 
appear, however, mingled with the adults as early as the latter part 
of April and the first of May, (in Southern [linois), and feed with 
them side by side. By the middle of May, the older individuals 
have matured, and then all stages may be found together upon the 
same plants; but the winged forms scatter widely, and in June and 
July are generally distributed wherever suitable food occurs. Young 
of all stages and adults of both sexes have been found by us, dur- 
ing this last summer, in every month from May to September in- 
clusive,—a fact which makes it difficult to say how many broods 
appear. It is certain that there are two, but whether more than 
that, it will probably be impossible to tell with certainty without 
rearing specimens in confinement. By the middle of October, the 
young have about all transformed, and from that time forward few 
but adults are to be seen. These frequent goldenrod, cabbage, turnip 
and other autumnal plants, and betake themselves in due season to 
their winter quarters, as already related. 
HABITS AND INJURIES TO VEGETATION. 
Both young and old of this species are quick to take alarm, the 
old flying readily, and the young dropping to the ground for con- 
cealment. On cool mornings and evenings, however, when stiffened 
by exposure, they are easily approached. They are, at this time, 
usually concealed among the expanding leaves. 
In the Flower and Vegetable Garden. 
As already reported in discussing the literature of this species, the 
attention of Mr. Harris was first drawn to it by reason of its mjuries 
to flowers and vegetables. Dahblias, marigolds, balsams and asters 
were mentioned by him as subject to its attacks, and he also found 
it so destructive to the foliage of the potato as seriously to diminish 
the produce of the fields in his vicinity. It principally attacked the 
buds, terminal shoots, and most succulent growing parts of these
