Head in general as before, the lateral wedge-shaped, brown streak 

 still more reduced by enlarged white mottlings. The green ground- 

 color more intense. The white dorsal line forms on top of the 

 hump a characteristic small white oval spot, often followed on the plant 

 by a still smaller one. The subdorsal line terminates at edge of anal 

 segment. Very frequently the stigmatal cream-white band contains 

 irregularly rose-colored oval spots and above the legs a yellowish, partly- 

 interrupted pedal line is formed. The green color from pedal line to 

 lateral line appears of a brighter green shade than the regions above ; 

 this is caused by an accumulation of very minute yellowish white con- 

 fluent dots and streaks most profuse in the middle of the green spaces 

 between dorsal, subdorsal and lateral lines spreading sideways. Tu- 

 bercles appear as minute black dots surrounded by small disc-like white 

 spots ; setae small, black and soft. Ventrally uniformly green but of 

 a fainter and duller shade. Stigmata oval, clay-colored with black 

 wing. On first segment the spiracle is only partly enclosed within the 

 white band, on eleventh segment it is situated above the band. Seg- 

 mental incisures appear as yellow rings when the larva is not out- 

 stretched. 



Stage V. — The larvae attain an average length of 18-20 mm. 

 Width of head 1.5 mm., width of middle of body 2.5 mm. All sixteen 

 legs equally well developed ; all geometrid-like habits are abandoned. 



Head rather flat, dull greenish white, with the brown or dark green 

 streaks as before, the lower wedge-shaped patch dissolved into irregular 

 reticulations. Mouth parts scarcely colored. Antennse pinkish, tipped 

 with black. 



Normally the dorsal line is diminished but distinct and uniform. 

 With many specimens it is interrupted posteriorly on the segments, or 

 appears composed of many irregular small whitish dots and often the 

 line is wanting in front of the oval, white spot on the hump. A rather 

 broad dark green shade attenuated in the middle of each segment seems 

 only to be caused by the action of the dorsal vessel ; subdorsal and 

 lateral lines as before. The cream white stigmatal band extends from 

 the buccal region to the extremity of the anal legs. This band is 

 variegated more or less with rose color or deep pinkish in irregular 

 spots, wavy double lines or even by a narrow, irregularly edged central 

 band. The yellowish-green color of dorsal and lateral area is still 

 more changed by irrorations formed by innumerable minute, confluent 

 yellowish-white dots ; below lateral line to pedal line the.se dots are far
