small but round and distinct, normal, no subprimaries. ia to iib on thorax sepa- 
rate, iv of abdomen below the corner of the spiracle, halfway to v on joint 11. 
Stage II — Head higher than wide, mouth broad projecting, squarish shallowly 
bilobed, flattened before. Green, the broad sutures of the high clypeus blackish; 
width 0.45 mm . Large ocelli black, in a close semicircle, jaws reddish. Body slender, 
moniliform, joint 12 enlarged dorsally. Feet on joints 9, 10, and 13. Translucent 
green, a narrow white subdorsal (below tubercle ii) and stigmatal lines. Tubercle 
iii on joints 5 to 7 and less so on 8, enlarged, black. Others also black but minute. 
Setae long, black, pointed; subprimaries present, normal. Feet all pale and concol- 
orous; no shields. 
Stage III. — Head high, flattened before, held obliquely, vertex against joint 2, cly- 
peus two-thirds to vertex, the paraclypeal pieces broader than before and concolorous 
with the head. Antennae moderate, blackish ringed. Green, ocelli black, whitish 
ringed, setae black; width 0.7 mm . Body humped up in the legless part; joint 12 
slightly enlarged. Green, tubercles whitish with narrow black hair points, iii on 
joints 5 to 7 somewhat larger and black, largest on joint 6, not very conspicuous. 
Fine, irregular white lines, viz, geminate dorsal, small and subobsolete, addorsal 
(above ii), subdorsal (below ii), and stigmatal somewhat broader than the others 
yet narrow. Setae blackish, rather long. Tubercles of joint 12 somewhat enlarged. 
Feet absent on joints 7 and 8. Thoracic feet brownish at tips. Spiracles pale, con- 
colorous; tubercle iv below the stigmatal white line. 
Stage IV. — Head as before, green, ocelli black centered; width 1.2 mm . Body slen- 
der, joint 12 a little enlarged; feet on joints 9, 10, and 13. Cylindrical, incisures a 
little narrowed. Translucent green, the J 1 sex glands in joint 9 large, pale yellow,

conspicuous. White addorsal line narrow, a broader subdorsal (above ii, over i), 
narrower lower subdorsal (below ii and near the subdorsal), narrow white stig- 
matal lines, all as before. Tubercles distinct, a little elevated, small, white, iii of 
joints 5 and 6 black. Feet concolorous, claspers and spiracles whitish; no shields. 
Setae blackish, rather long. Tubercle iv behind the spiracle on joint 5, below the 
lower corner on 6 to 8, opposite the corner on 9 and 10, halfway to v on 11, at 
the lower corner on 12. Tubercles i and ii on joint 12 in a square. Lines irregularly 
edged and broken at the extremities. 
Stage V. — Head rounded squarish, slightly bilobed, flattened before, oblique, free 
from joint 2. Translucent shining green, antennae and palpi yellowish, ocelli black; 
width 1.8 to 2 mm . Body normal, moderate, joint 12 enlarged dorsally. Green, no 
shields marked with white lines. Addorsal narrow, crinkly; subdorsal (between 
i and ii) broader, upper lateral (below ii) and stigmatal narrow. Tubercles white, 
iii of joints 5 to 7 black, but small and inconspicuous. Spiracles white, narrowly 
black-rimmed. Feet green, the abdominal ones on joints 9, 10, and 13. Tubercle 
iv below the spiracle. Setae blackish but obscure. The larva occasionally comes 
darker colored. The ground color is darker green, more transparent, especially 
along the dorsal vessel and above the stigmatal line, making the lines more con- 
trasted and whiter. Tubercles iii are black the whole length, largest on joints 6 to 8, 
but plain on 5 to 12. Head brownish on the lobes.
