joint is linear, as long as the third and half the fourth taken 
together. The two last joints are very slender, the: last slightly 
shorter than the other. 
The beak is long and slender, reaching to the last pair of legs, 
and may be either pale or dark, but is always black at tip. 
First Stage.—(Plate XI, Fig. 2).—Shortly after hatching, the 
young plant bug is of a pale green or sulphur-yellow color; about 
a twentieth of an inch long, and fifteen hundredths of an inch wide. 
Its general form is that of an ellipse with flattened sides, both ends 
being rather obtuse, and the sides nearly parallel, diverging very 
slightly, however, to the fourth abdominal segment. 
The head is triangular, a little longer than the first thoracic seg- 
ment, the color slightly darker before the eyes. The thoracic seg- 
ments are similar to the abdominal, but about twice as long. They 
are of equal width, but the first is a little longer than the second. 
There are ten segments in the abdomen, counting a rudimentary 
anal one. The first two are very short and closely united; the re- 
mainder of about equal length, except the ninth, which is the longest. 
On the dorsum of the third abdominal segment is a median orange 
spot. 
The legs are very long, the hind tibize being half as long as the 
whole body. The tarsi are two-jointed, the first joimt very short 
and obliquely articulated, the second four or five times as long and 
cylindrical. The legs are white, except an orange ring at the prox- 
imal end of the tibie. 
The antenne are four-jointed, and nearly as long as the body. 
The first joint is short and thick, the remainder more slender and 
equal, each being about twice as long as the first. All the articles 
are white, except the last, which is orange. 
The beak is very large and long, reaching to the last abdominal 
segment. The joints are four in number, and of nearly equal length. 
In slightly older specimens in this stage, the antenne, tarsi, and 
the terminal joint of the beak become dusky, and a transverse black 
mark appears at the posterior border of the orange abdominal spot. 
The entire surface, in this stage, 1s sparsely covered with short 
black hairs. 
Second Stage.—(Plate XI, Fig. 3).—In this stage the length is 
the twelfth of an inch, and the greatest width half as much. The 
abdomen is now much broader than the thorax, having an ovate 
form, with the third and fourth segments the widest. The second 
and third segments of the thorax are wider than the first, which 
narrows forwards, being in front scarcely wider than the head. The 
third segment is hardly more than half as long as the second, and 
the hind angles of both these are free, and somewhat produced 
backwards. A quadrate, median black spot occurs on the suture 
between the third and fourth abdominal segments, divided trans- 
versely by a slit-like opening of the gland within. 
On the thorax are four more or less deeply marked black spots 
of circular form, two on éither side of the middle of the first and 
second segments.
