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 larvse 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 stigmatai stripes, all equidistant. 

 The stripes run from first segments to the last, the stigmatai 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- 

 matai 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 j the red line with different individuals is more or less intense and 

 when most prominent it is edged below with yellow and the stigmatai 

 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 stigmatai 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 stigmatai 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
