except the upper and posterior parts which are pale brown where 

 usually withdrawn into segment 2, eyes black; ceiwical shield 

 darker than rest of body with dorsal white line less prominent 

 than on other segments, the subdorsal lines more prominent. 

 All prolegs now fully developed. 



4th stage — 15-1 7mm. ; much more mottled and variegated 

 than preceding stage with black, browns, olivaceous, yellowish 

 and whitish, the darker colors predominating ; two more or less 

 conspicuous sub-dorsal rows of black spot? on segments 7-12, a 

 broad paler region on dorsum between these, in the middle of 

 which is a series of obscure lozenge-shaped darker spots; head 

 mostly black except the periphery (portion covered when re- 

 tracted) which is pale brown; two conspicuous whitish sub- 

 dorsal spots on segment 6; posterior sub-dorsal parts of seg- 

 ment 12 and upper parts of segment 13 yellowish; spiracles 

 black, a yellowish streak below them ; tubercles not conspicuous, 

 same color as place where situated, hairs short; 12th segment 

 quite swollen, 



5th and 6th stages — very similar to fourth stage, but usually 

 darker, almost black. When full-grown 26-32inm. long. When 

 disturbed the caterpillars drop from the leaf where feeding 

 and mostly lie straight and rigid, feigning death. When smaller 

 they dropped and curled up when disturbed. 



The caterpillar in breeding-cage ate leaves of sweet potato, 

 bean, Portulaca, grass and "honohono" {Commelina). They 

 did not take readily to sugar-cane. In nature they have not 

 been found injuring any cultivated plant or crop, but it is 

 possible that they might do so later on if they become more 

 abundant. 



The five molts occur at intervals of 3-9 days, usually about 

 4 days ; and the caterpillars become full-grown in 30-40 days. 

 The pupa is formed in the soil, an inch or two below the sur- 

 face. It is 13-1 5mm. long; uniform medium brown, eyes black, 

 wing-, leg-, and antenna-cases extend to apex of 4th abdominal 

 segment; articulations between segments 4-7 movable; a row 

 of about 20 pits on dorsal part of basal margin of segments 5, 

 6 and 7, from the ends of these rows a band of punctures extends 

 around the ventral side; apex of abdomen blunt and rounded, 

 with two dark S]nnes placed near together, their tips converging, 

 slightly ventraliy curved. Pupal period 12-14 days.
