terior margin subcurved. Mesothorax, equal to prothorax in length at middle, but 

 longer at sides where rudimentary wing-pads are apparent. Metathorax, very short; 

 posterior margin slightly subcurved, not prolonged at sides as mesothorax. Abdomen, 

 pyriform: slightly marginate. Legs and antennae, long; slender; strong; clothed with 

 fine pubescence; last segment of antennae bearing longer coarser hairs. Length of an- 

 tennae, 1.92 mm. to 2.05 mm. I. 25 mm. to .27; II. .599mm. to .65 mm.; III. 50 mm. 

 .52 mm.; IV. .60 mm. to 63 mm. Hind tibia, .982 mm. to 1.00 mm. Entire body and 

 legs clothed sparsely with short fne black setae. Color, bright apple green; head rather 

 yellow, and thorax yellowish with faint but regular mottlings of the bright green. Two 

 faint small dusky spots on prothorax and two rather wider apart on mesothorax. Third 

 abdominal segment with a bright orange yellow circular spot and a smaller dusky spot 

 on the caudal margin. Legs, dull yellowish green, translucent. Femora faintly banded 

 twice with red-brown; proximal end of tibiae red-brown; tarsi dusky to black. Anten- 

 nae dull greenish yellow, tinged with brown at each end of each segment except I, IV 

 entirely reddish brown. Eyes dark red. This coloration varies to a dark form in which 

 the head and thorax are overlaid with dusky color, and the legs and antennae are dark- 

 er. Length of body, 2.00 mm. to 2.2 mm.; width of head at eyes, .59 mm. to .60 mm. 



Fourth Instar. Body broad and stout; pyriform in outline, being broadest at 

 third abdominal segment. Head, smaller than before compared with the rest of the 

 body, unchanged in form. Prothoiax, as in third instar. Mesothorax, very slightly 

 longer than prothorax, and twice as long as metathorax. Wing pads prolonged to 

 reach the anterior margin of the third abdominal segment, the tips of the first and sec- 

 ond pair coinciding at this point. Abdomen, broad, marginate; pointed at tip. Legs and 

 antennae, long and slender. Length of antennae, 2.47 mm. to 2.6 mm. I. .31 mm. to .32 

 mm.; II. .875 mm. to .93mm.; III. .64mm. to .65 mm.; IV. 65mm. to. 71mm. Hind 

 tibia, 1.37 mm. to 1.43 mm. Color, green in general appearance. Head light yellowish 

 green with five longitudinal stripes of reddish brown converging but not reaching 

 posterior margin. Eyes reddish brown. Prothorax, light green, with two prominent 

 black spots situated laterad of the median line, towards posterior margin. Several 

 dusky markings surround these spots, very variable in form. Two black spots also oc- 

 cur on mesothorax, slightly wider apart and similar dusky streaks and markings. Meta- 

 thorax, dusky green and very faintly marked. Abdomen, bright green, each segment 

 with two faint narrow transverse bands of reddish or dusl-y brown. The caudal mar- 

 gin of third abdominal segment bears a large black spot; the larger yellow spot has al- 

 most disappeared. Legs and antennae yellowish brown with several bars and markings 

 of darker reddish brown. Two prominent reddish bands on each femur. Tarsi and tip 

 of antennae dusky to black. Length of body, 2.53 mm. to 2.68mm.; width of head at eyes. 

 .78 mm. to .82mm. 



Fifth Instar. Body, very stout, broad and thick. Head, comparatively small. 

 Prothorax, lateral margins strongly divergent caudally. Mesothorax, one third longer 

 than prothorax and seven times the length of metathorax. Wing pads extending to an- 

 terior margin of fifth abdominal segment. Abdomen, pyriform; broad; strongly mar- 

 ginate. Antennae, long; slender; clothed with fine pubescence and coarser hairs on ter- 

 minal segment. Length 3.20 mm. to 3.45 mm.; I. .37 mm. to .405 mm.; II. 1.2 mm. to 

 1.35 mm.; III. .81mm. to .88mm.; IV. .73 mm. to .80mm. Legs, long and slender; 

 tibiae clothed with many short, black setae. Length of hind tibia, 1.9 mm. to 2.15mm. 

 Colors very variable; general appearance light to dark green. Head, yellowish, with 

 five longitudinal red stripes slightly darker than in fourth stage. Eyes dark reddish 

 brown. Prothorax light green with two large black spots as before and varying mark- 

 ings of dusky olive. Mesothorax, strongly marked with dark olive, bearing the usual 

 large black spots; metathorax, less distinctly marked. A median longitudinal line of 

 light green always occurs on entire length of thorax, varying considerably in width. Be- 

 fore the final moult the wing pads usually become very dark at the tips, often taking on 

 rust-red color. Abdomen bright green; third abdominal segment bearing a large round
