of head green; the horns brown in front, 
green behind; the space along back head 
and on side green ; ocelli black. 
of this stage about 5 days. 
Duration 
After 2d moult.— Length 7.6 mm. ; 
shape as before ; color uniform dark green ; 
all the lines as before ; head as before ; the 
horns 1 mm. long to end of forks, the forks 
being about one-third of this ; below each 
horn on side of face avery short cone; 
down side of face are now fine spurs, the 
upper one longest, the rest gradually di- 
minishing to avery short one quite at base ; 
other spurs as before; the color of head 
varies in individuals, the upper front face 
and the front of horns being always dark 
brown, the rest of face greenish-white. In 
some examples the brown extends half way 
down, fading into vinous at its lower edge ; 
in one a pale brown stripe extended from 
base of horn at side to the outer end of 
mandibles ; the back of head always green ; 
the spurs green, the longer ones usually 
brown at tips. Duration of this stage 3 
days. 
After Sd moult.— Length 14 mm.; 
body white in the middle ; color more yel- 
low, of one shade; the tubercles and all 
lines as before. In one example, as this 
stage proceeded, a minute yellow spot ap- 
peared on the anterior edge of each seg- 
ment from 6 to 11, on dorsal line, but in 
the others these spots did not appear till 
the subsequent moult. Head shaped as 
before, with the processes and spurs as at 
preceding stage; colors variable. Most 
have the upper part and front horns vinous- 
brown, with a slight brown stripe from 
below horns to end of mandibles, and a

shorter one down side to top of the ocelli. 
One had the green restricted to a little 
space in front, and a little stripe on side 
between the two brown stripes before spoken 
of; another had all the face green, the 
horns alone being brown; another has a 
narrow rim of brown along the top, and 
two side stripes. In all the front of horns 
is brown, green behind, and the green 
spurs or prongs behind have brown tips. 
To next moult 4 days. 
After 4th moult. — Length 21 mm. In 
from 4 to 11 days after the moult the lar- 
vae pupated. 
Mature Larva. — Length % 29 
mm., 2 36 mm; greatest breadth % 6.1 
mm., of 2? 7.6 mm,; stout, thickest in 
middle, the dorsum greatly arched, taper- 
ing pretty evenly either way, so that seg- 
ments 2 and 12 are of about same diame- 
ter ; ending in two small, conical, divergent 
tails, 1.8 mm. long, one placed on each 
side of the segment, the space between their 
bases being the convex surface of the seg- 
ment. Color of whole surface, dorsum 
and sides, from segment 2 to ends of tails, 
one shade of yellow-green; next over feet 
a little bluish, the under side pale ; thickly 
sprinkled with little yellow tubercles, which 
are distributed equally over whole surface, 
and are distinctly separated. These are 
mostly of two sizes, one twice that of the 
other; some are pointed at top, some 
rounded, and each gives out a short white 
hair. There are neither stripes nor bands, 
but a fine line of tubercles like those else- 
where, but close set, runs from head to end 
of tail, at each edge of the dorsal area.
