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 hairs 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 rede ish. 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 50mm. Length from head to fork 

 of tail?, 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 ornamentation 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 II 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-
