out like a stick. They are fond of spinning small networks over the 
leaves especially when moulting and drop on a thread when disturbed, 
but these customs are gradually abandoned during their moults. Before 
changing their skins they turn sordid olive green, moult during the 
night and eat their cast-off skins except the head shell. 
After first moult .—The larvae are bright yellowish green, slightly 
paler ventrally. Skin very transparent, contracted. Head compara¬ 
tively smaller than before of very pale tan-color, mouth parts light 
brown, ocelli darker. First segment somewhat swollen, hump much 
produced. An indistinct stripe forms dorsally, more distinct from 
seventh to last segment, also a very pale whitish green lateral stripe. 
After second moult. —They change to bright, glossy pea-green with 
pale bluish white dorsal, lateral and stigmata! stripes, all equidistant. 
The stripes run from first segments to the last, the stigmatal continued 
by a narrow line above cremaster. Cervical shield indicated by a slight 
depression and still brighter green, hump on top also more shiny. 
After third moult —The stripes turn clear, heavy white. The stig¬ 
matal one is bordered above by a cherry-red line. The larvae vary 
much in deeper or lighter shade of green, from pea-green to bright 
olive; the red line with different individuals is more or less intense and 
when most prominent it is edged below with yellow and the stigmatal 
stripe appears cream-colored. 
After fourth moult. —The ground color is still more glassy and trans¬ 
parent pea-green: stripes chalky, finely wrinkled. The dorsal stripe 
rather even, the lateral one almost uniform on the three first segments, 
but then widening in the middle of the segments and tapering in the 
incisures forms a chain of elongated spots. The stigmatal stripe is 
broken up into eleven irregular, half-moon shaped spots ; conjoined. 
The humped nth and 12th segments have only one spot, but enlarged ; 
these spots are bordered above with cherry-red and shaded with yellow 
on the edges and junction. A pedal line of yellowish-white, oblong, 
irregular spots forms above the abdominal feet and on the tenth segment. 
After fifth moult. —The larvae attain their maturity. Full-grown 
they are nearly cylindrical, about 32 to 35 mm. long, width 4.5 mm. 
All 16 feet normally developed. Eleventh segment forming a hump 
slanting to cremaster. The few short delicate hairs distributed as before, 
but hardly perceptible. The finely granulated skin folded, especially 
on stigmatal area. Ground color deep, glossy pea-green, very transpa¬ 
rent ; head and legs more yellowish green; cervical shield and hump 
still brighter green. Dorsal and lateral stripes chalky white, finely
