did not take notes, inasmuch as they resembled the progeny of the other 
cerurine referred to above. 
Stage III .—Larva molted October 30th, when 22 days old. Length at rest from 
head to fork of tails, 14 mm. Stemapods, 8 mm. Breadth of joint 2, 5 mm. 
joint 7, 4 mm., joint 12, 3 mm. Width-of head, 3 mm., length 3.5 mm Vertex 
marked by a triangular green ) oke, the point of which passes into the median line or 
dorsal band. Prothoracic horns now quite rudimentary. A round brown spot quite 
prominent each side of head, I mm. in diameter. A few white hairs on face. 
Mandibles greenish-white and tinted lilac. In centre of face a brown dot, surrounded 
by an oval, light brown border above mandibles. On each side of this oval two longi¬ 
tudinal lines of same color and length. Above the brown dot a triangular depression 
lilac edged, which has passing through the middle a whitish longitudinal bar. 
On the anterior part of segments 6, 7 and 9, is a small, whitish triangular spot 
each side of median line, enclosing a purple oval which posteriorly is surrounded by 
three or four whitish dots. Joint 10, marked by faint dots of same color. Anterior 
ridge connecting rudiments of former prothoracic horns, of much lighter color than 
the rest of joint 2. Joint 4 has an elliptical purple patch, and joint 5, one of ovoid 
pattern on its dorsal surface. The purple of entire dorsal ornamentation bordered by 
a bright yellow line, which on anterior half of all segments is half a millimeter in 
width. This yellow line starts from below the insertion of former prothoracic pro¬ 
cesses, and is lost at the insertion of stemapods. Lateral surface green, dotted and 
mottled, with yellowish-white and purple spots. A few lairs on lateral surface. 
Spiracles tinted brown. Thoracic and abdominal legs a brighter green than the 
lateral parts of larva. Lateral surface of thoracic feet splashed redcish. Clasping 
surface whitish. Stemapods anteriorly tinted green, and annulated jellow from the 
middle to the flagellum. Lateral surface green covered by minu.e, purple papillae. 
Mature Larva , 35 dajs old, observed November 12, 1897. Length at rest 
including stemapods, 40 mm., when in motion 50 mm. Length from head to fork 
of tails, 32 mm., stemapods, 8 mm. Length of head, 3.5 mm., width, 3 mm. 
Width of joint, 3, 6 mm , of joint 7, 7 mm , joint II, 6 mm. Head purple, vertex 
green, antennae white. A yellow spot indica'es location of former prothoracic horns. 
The border of entire dorsal ornamen'ation is now milk-white from joint 2 to 13. 
The color of dorsum between this border is greenish white in some places and 
milk white in others. 
The color intermediate between the whiter ed dorsal surface and whitish border 
line, has now changed to a lilac tint. Lateral surface of larva spotted and marked 
purple. Thoracic feet whitish, splashed purplish. Abdominal feet whitish and 
above claspers purplish. On the abdominal surface of segments, between joint 11 to 
venter, runs a longitudinal, median purple line. A few white hairs below spiracular 
line. Spiracles brown with a longitudinal, yellowish dash, ringed greenish-yellow. 
Anterior part of stemapods concolorous with body, and posterior part of these anal 
filamental organs is yellow. Entire surface of stemapods studded purple. When 
prolonged the extensive part of outer third of ‘‘tails,” bright purple annulated 
lavender. Under a strong lens the purple spinules covering the stemapods, were 
seen to support a hair. 
Cocoon .—In all thirty-eight cocoons were observed. Of these 37 be-
