The legs are as before, except that the tibial rmgs are more highly 
colored, and there are more or less evident traces of a second red- 
dish ring below, as well as of two femoral rings of the same color, 
near the tibio-femoral articulation. 
The antenne are relatively shorter than in the first stage, owing 
to the greater development of the body, and reach about to the fifth 
abdominal segment. Their color is darker, all the joints being red- 
dish dusky, with white articulations. The second joint has also a 
paler shade at the middle, and the basal joint is nearly white. In 
the more highly colored specimens the antenne are distinctly ringed 
with pale at the articulations, and at the middle of the second joint. 
The tarsi (still two-jointed) and the tip of the beak are almost black. 
Third Stage. (Plate XII, Fig. 1.) This stage differs from the 
preceding chiefly in the oreater size, the length “being now eleven or 
twelve hundredths of an inch, the width about half the length; and 
in the greater development of the posterior angles of the meso- and 
metanotum, which now begin to take the form of wing pads, and 
reach backwards so as to enclose the ends of the first, and often 
of the second, abdominal segments. The abdomen is now about 
twice as wide as the prothorax; and the beak has the joints 
unequal, the second being the shortest. The legs and antenne are 
more highly colored than before; there is a black spot beneath the 
posterior angles of the prothorax. 
In the more strongly marked specimens, the head, abdomen, legs, and 
antenne, are more or less strongly suffused with crimson, the head 
having a median longitudinal red stripe, with two short oblique ones 
on each side. The thorax is dusky, marbled with paler, with a 
median white line, and pale spaces surrounding the four black spots, 
and 1s sometimes variegated with crimson. ‘The under side of the 
head and the tip of the abdomen beneath are also marked with 
erimson. 
Fourth Stage, or Pupa. (Plate XII, Fig. 2.) The “pupa” 1s de= 
cidedly broader than the other stages, the average length being 
twelve hundredths of an inch, and the width seven hundredths. 
The head and the prothorax have the adult form, and the secutellum 
is well marked as a semi-circular, bimaculate, median part of the 
second thoracic segment ; this segment (the mesonotum), in fact, now 
nearly covers the third, or metanotum. 
The wing pads now extend to the fourth abdominal segment, and 
are about equal in their greatest length to the first two segments 
of the thorax taken together. They are irregularly marbled and 
lined with dusky, while the prothorax, besides the two black spots, 
shows four longitudinal dusky or crimson lines parallel with its margins. 
In some the abdominal sutures are crimson, and a crimson band 
crosses each segment. In fact, the pupe show an extraordinary 
variability of color, evidently independent of age, and probably re- 
lated to sex. 
The tarsi are still two-jointed, the second joint long and slender, 
with the basal half pale, giving the tarsi a banded appearance. 
The antennex are less distinctly ringed than before; and the articles 
diminish in thickness from the first to the last, and in length from 
the second. In some specimens, a pale v-shaped mark on the
