3 to 13 ; and on middle of side from segment 
7 to 10. Sometimes from segment 6 to 11 
is a short oblique line, made up of same 
tubercles, pointing forward and downward ; 
on the medio-dorsal line on segments 6 to 
11, on the anterior side of each segment, 
is a little rounded yellow spot, smallest on 
6 and 11, and often indistinct, on 7 to 10 
clear colored. The largest spot observed 
measured but 0.08 mm. in diameter. Im- 
mediately after the fourth moult all these 
spots were indistinct, but they became con- 
spicuous as the stage progressed. Feet and 
legs bluish-green; head  sub-quadrate, 
about as broad as segment 3, as broad as 
high, the sides and also the base a little 
convex, the top deeply depressed in front 
at the suture ; the vertices conical and each 
bearing a branching process or horn. These 
all stout at base, tapering, 2 mm. long, 
forked near top, the forks being 0.5 mm. 
long; about the middle part are set five 
short conical spurs; at base behind are 
two spurs on inner side and one on outer 
side ; down the side of face three in verti- 
cal line, the upper one long, the others 
gradually diminishing, all bent downward ; 
between the last of these and the ocelli, a 
short spur; many minute spurs are found 
down back and sides to mandibles ; whole 
surface of head and horns thickly and shal- 
lowly pitted, and covered with a fine whit- 
ish down; the spurs and horns beset with 
quite long hairs on their sides and tops; 
the color of face is variable ; some have it 
blue-green, vitreous, along the top vinous- 
brown ; a whitish vertical stripe from in- 
ner base of each horn down the suture, and 
another beginning a little below horn on 
the side, and running to end of mandibles ; 
one example had nearly all vinous-brown, 
there being merely a little green over man- 
dibles ; in this one even the back of horns 
and head was brown; in all others these 
parts were green, the fronts of the horns 
brown; some had the upper part of face 
vinous, with the fine stripes paler brown ; 
one had the whole face green, no brown, 
with fine paler stripes. 
CurysaLis. — Length 23 to 25 mm. ; 
breadth of the largest at wing cases 8.1 
mm.,of abdomen 6.6 mm.; depth of ab- 
domen 9.1 mm.; compressed laterally ; 
the outline of ventral side convex ; the ab- 
domen prominent dorsally, much arched, 
sharply carinated, the carina finely and ir- 
regularly serrate and on it the anterior 
edge of each segment is produced and is 
marked on each side by a shining black 
dot ; the last segment ending in a long bi- 
furcated pad of hooklets ; the thoracic seg- 
ments roundly excavated below mesono- 
tum, and the sides there also excavated in 
the direction of the bases of the wings; 
mesonotum angular, a little rounded at 
summit, with a low and narrow keel; head 
case produced, sub-conic, the projections at 
vertices prominent, sub-pyramidal, bent in 
at the top; color delicate yellow-green, 
thickly covered with pale yellow dots and 
patches over the abdomen, and beyond, on 
dorsal side to top of head, with irregular 
pale yellow inscriptions; many of these 
marks also on the wing cases transversely 
between the nervures; the neuration of 
the wings distinct; a yellow line passes 
along the keel from the last segment to top 
of head case, and a little beyond top of 
mesonotum sends two forks to the projec- 
tions of head; another line, but white, 
passes along the posterior edge of the wing
