die than forward of it, and are bluntly rounded at each end with the 
tip slightly angular. The antennae are from a third to half as long as 
the body, and the legs are of corresponding length. The honey tubes 
are merely elevated angular points. These young lice are of a dull 
black color, with the antennae and legs pale, the tips of the antennae, 
the feet, knees and hind thighs usually varying from smoky to black. 
A variety has the body of a grayish or lurid green color, but com¬ 
monly changing to black as it approaches maturity. These green 
larvae are more common in the early part of the season. And on 
some kinds of plants most of the young lice are of this variety. 
The pupa varies remarkably. When the insect first attains this 
form it is smaller and destitute of some of the most prominent char¬ 
acters which it subsequently presents. It is but 0.07 long, sometimes 
only 0.06 in length, and is of a dull sooty black color, its legs and 
antennae very obscurely varied with pallid, the abdomen without any 
mealy-white spots, and the thorax not swollen nor abruptly widened. 
Indeed, it is only recognized as being a pupa at this time by the wing- 
scales on each side of the base of the abdomen, these being small and 
of a dull greenish color. The basal half of the thorax begins to become 
perceptibly swollen and to take on a dull green color, and white spots 
on each side of the back become more and more distinct, and it gradu¬ 
ally thus acquires its complete pupa form and characters. 
In its perfect pupa state it is 0.08 long, sometimes slightly over this, and is oval 
■with the opposite sides nearly parallel, the anterior end bluntly rounded and the 
opposite end tapered to an obtuse attenuated point. It is slightly flattened and con¬ 
vex both on the back and the under side. The head is nearly cubical, rather more 
■wide than long, separated from the body by a transverse deeply impressed line, the 
eyes projecting in form of a rounded protuberance on each side at base and occupy¬ 
ing more than half the length. It is sooty black, sometimes dark dull green, often 
with the vertex slightly dusted over with a white mealy powder, imparting to it a 
grayish tinge. The antennae are half as long as the body, more slender toward their 
tips, black, with a dull pale tinge toward their bases, which is sometimes scarcely 
perceptible, sometimes very distinct, and sometimes the whole of these organs are 
pale with only their tips black. The thorax is composed of two very distinct and 
dissimilar parts; the anterior part small, transverse, no wider than the head, 
sooty black, often dusted like the head with a white mealy powder; the posterior 
part large, twice as broad as the anteriox', abruptly widened, transverse, having a 
peculiar swollen and blistered appearance, and being of a dull lurid greenish color, 
the shoulders rounded, an obtuse longitudinal impression on each side of the back 
dividing this part into three lobes, the lateral ones sometimes paler than the middle; 
the wing-sheaths appearing as oval scales, one on each side, projecting backward, , 
appressed to each side of the abdomen and reaching about half its length, but being 
sometimes more sometimes less developed, black, often pale toward their bases. The 
abdomen forming about half of the total length, its tip tapering to an acute and often 
an acuminate point, color sooty or coal black, sutures marked by transverse impressed
