<']ypeus itself tlie same color; ocelli dark; a few setie; width, 0.7 mm. A red-brown dorsal Hue 

 witli niarkiugs of the same color, tiuely yellow dotted, along the lateral area and covering the 

 ■whole of joints 5, 7, 10, and 12; the rest of the body pale yellowish, especially on joint 8. The 

 abdominal feet on joints 8 and 9 and the thoracic feet are pale. Tubercles 1 with enlarged bases, 

 forming slight dorsal prominences on joints 2, .5, and 12. Anal feet brown, elevated. Setae dusky 

 with glandular tips, normal, six present with five or six sets on leg plate. 



" Third stage. — Head small in proportion to the body, bilobed with a large tubercle at apex of 

 each lobe, rather flat before with several setne ; pale brownish white, shaded with brown posteriorly, 

 with a vertical brown band before ocelli extending to vertex of each lobe, the pair connected by 

 an angular cross band above clypeus and again, faintly, near the vertex; clypeus greenish, ocelli 

 dark ; width, O.O.} mm. Tubercles 1 with enlarged bases ; a slight hump on joints 5 and 12 bearing 



1 near the apes ; a pair of tubercles in place of the cervical shield. Body at first yellowish, except 

 the sides of joints 2-4, which are green. Later shining leaf green. A purple-brown dorsal band 

 dotted with white extends from joint 2 to the anal feet, widening a little on the middle of each 

 segment, covering tubercle 1 on joint .5, but on joint 6, 1 is bright yellow; the brown color covers 

 the whole of joint 7, even the foot, and stains the posterior half of joint 6 and a stigraatal patch on 

 joint 5. Tubercle 1 on joint 8 yellow. The brown band covers 2 on joints 9 and 10 and stains the 

 foot on joint 10, extending up anteriorly and also posteriorly on joint 11; it covers tubercle 1 only 

 on joints 11 and 12 and, becoming very narrow on joint 13, passes to the anal feet. A faint white 

 subdorsal band, stained with yellow, most distinct on joints 8 and 9, and forming a somewhat 

 oblique yellowish mark on joint 11, suggesting the usual V-mark of Schizura larvse. The green 

 ground is partly rei)laced subventrally by whitish streaks. Thoracic feet pale. Setae pale, with 

 glandular tips. 



'■'■Fourth stage. — Head much as before, but a brown line extending up from the ocelli is all that 

 is left of the brown on the sides of flie lobes, and the band connecting the vertical lines above is 

 broken. "Width, 1.5 mm. Body as before in color, but the setae stiff, distinct, not glandular. The 

 green of the sides is considerably broken up by whitish streaks; tubercles 1 on joint 6, and 1 and 



2 on joint 8, are yellow. As the stage advances the brown dorsal baud partially fades out, the 

 white subdorsal line, broken on joint 11, becomes more distinct, and its posterior part forms a 

 distinct V-mark on joint 11. Tubercles 1 on joints 5 and 12 make slight, but distinct, furcate 

 processes. These disappear in the next stage. 



'■'^ Fifth stage. — Head small, flat before, rounded, higher than wide; white, with a faint yellowish 

 tinge; from each side of base of clypeus a band extends to vertex of each lobe, cut by a small 

 spot of the ground color each side of the clypeus and a larger one opposite apex of clypeus and 

 narrowly bordering clypeus above; this band is purple-brown, mottled with round dots of the 

 ground color; a similar fainter band behind the ocelli. A very slight prominence on joints 5 and 

 12, low, scarcely even a hump ; otherwise the body is smooth, tubercles absent, setae small, dark, 

 but tubercle 6 and those on the leg can be distinguished; anal feet elevated. Body green, clear 

 on the sides of joints 2-4 with a dorsal purjjle-brown band mottled with white, which tajiers and 

 ends at joint 5. A white subdorsal shade on joints 5-13, diftuse downward and cut by oblique 

 lines of the ground color (green), broken on joint 11, the posterior part continued forward frorn 

 joint 11 on joint 10 and becoming yellow, forms a V-mark supplemented by a few dots on joints 9 

 and 11. A distinct yellow patch surrounds tubercle 1 on joints 6-8 with a yellow dotted dorsal 

 shading; the spots 1 on joint 8 separated by a Y-shaped brown mark (in some cases the sides of 

 joints 5-8 are more or less covered with dark brown, mottled with whitish, being remains of the 

 brown marks of the previous stage), and the brown usually prevails in a band from the spiracle 

 on joint 5 back to the abdominal feet. Bases of the feet around tubercle 6 waxy white, this area 

 bordered by a rather irregular brown mark. Anal plate and feet dark. Spiracles pale brown. 

 Thoracic feet tinged with reddish."
