Boiled in a solution of KOH, it colours the liquid greenish. The

 which, except joint 3, bear hairs. Length 350-361 mm. Approximate 

 formula 423 (17) (56), or 472 (13) (56). The antennte are variable, but 

 in all the specimens examined, joint 4 was the longest and joints 5 and 6 

 the shortest. Length of joints in //. : (i), 49; (2), 58-62 ; (3), 49-62 ; 

 (4), 80-89 ; (5), 22-29 ; (6), 27-29 ; (7), 49-62. Legs ordinary; the 

 coxa of the first pair of legs, with a short apical hair and several short 

 spines ; trochanter with the long side convex and bearing a long hair ; 

 the articulation between the tibia and tarsus is indistinct ; tarsus with a 

 constriction near the middle ; claw short ; digitules twice the length of 

 claw, large, of equal size, bulbous at base, and broad and flat at the end ; 

 tarsal digitules slender, with the ends slightly expanded. Length of joints 

 of first pair of legs, in // : coxa, 80 ; femur with trochanter, 200 ; tibia, 

 120; tarsus with claw, in ; tarsus without claw, 89. The tarsi of the 

 other legs are not constricted. Mouth-parts well developed, placed just 

 posterior of the first pair of legs. Rostral loop short, not extending to 

 the second pair of legs. Anal ring with ten hairs. Anal plates small ; 

 the outer angle rounded, the two outer sides nearly equal, the postero- 

 lateral side being convex and just a trifle shorter than the antero-lateral- 

 Around the lateral margin there is a simple row of small hairs placed 

 wide apart. 



ft scale small, plain, white, very frail, composed of 7 lateral and 2 

 dorsal plates. General shape elliptical, the posterior part slightly 

 narrower than the anterior : dorsum convex. Length, 1.355 mm.; 

 width, .830 mm. Found on the branches and on the under side of the 

 leaves. 



Larva, just hatched, yellowish green in colour, oval in outline, with 

 the posterior end of the abdomen slightly acuminate and ending in two 

 long setae. Eyes dark brown. Margin of body serrated and bearing a 

 few short hairs. There are two groups of stigmatal spines on each side, 

 each composed of two very short and one long club-shaped spines. 

 Antennae six-jointed, joints 3 and 6 about equal in length. Legs
