Stage III. Head rounded ([uadrate, wide; vinous l)Iaek, a broad mottled erect 
white band on the face of each lobe, diver<fent below; a while trian;;le in the elypeus; 
epistoma and bases of antennae white; width, I nun. Body robust, weakly annulate, 
colored as before; the dorsal and other white patches more mottled and cut by the 
jiround color, which is darker, vinous blackish, 'rnbereles in the lateral patches 
lumpy white. 
Stage 7F. Head as before, black, epistoma white, white tlilfnsed dotlings 
broadly over the angles of the lobes and slightly in the elypens; rounded (piadrate, 
as high as wide, antennae and mouth dark; width 1.4 mm. Body moderate, normal, 
uniform; vinous black, annulate; dotted white subdorsal line on joints 2-4, a cordate 
white mark, containing a dark dot in each lobe on joints 5-10, centered by tubercle i, 
the white cut by the annulet incisures, obscurely joined by a geminate dorsal band 
posteriorly; on joints 10-13 a waved broken subdorsal banil, roughly imitating the 
cordate marks; a series of segmental white patches on joints 7-9, joined by a broad 
white band on joints 8-12, becoming a narrower band anteriorly and posteriorly, 
running narrowly onto the foot on joints 10 and 13. Venter obscurely white streaked, 
with a pale medio-ventral band, dark centered; small white dots laterally, especially 
at tubercles ii and iii. Orange blotches in the white lateral markings. With growth 
the markings faile and become yellowish, bnt leave a bright white lateral spot on 
joints 5, 6 and 7, largest on joint 7. 
Stage V. Head rounded cpiadrate, thick, as high as joint 2, scarcely bilobed; 
dull black, with angular white dots over the sides and in elypeus, forming a short 
black-dotted band on the vertices of the lobes; epistoma white; width, 1.8 mm. 
Body robust, uniform, feet normal; leather brown (dead-leaf) dotted with black; a 
waved smoky black subdorsal line, the cordate white si()ots lost in the brown ground, 
leaving only a little white mottling about tubercle i, and whitish bars on the otherwise 
concolorous cervical shield and anal plate; faint linear white lateral line, black edged; 
large white spots about the spiracles on joints 5-10, faint posteriorly, involving 
tubercle iii by a lobe; an orange spot about tubercles iv and v. Venter with numer- 
ous indistinct lines of blackish and brown, snbgranular, dotted by whitish. Thoracic 
feet dark; the abdominal ones of joint 10 white lined, of 13 large, marbled, with a 
whitish l)and anteriorly that joins a faint stigmatal band conn)osed of the confluence 
of the stigmatal patches on joints 9-13'; a reddish tinged stigmatal band on joints 2—4. 
Stage IT. Head rounded (piadrate, thick, the vertex roundedly divided, level 
with joint 2; colored as before but the white more extended, .so that the ground color 
is white with crinkled and dotted dark brown marks, which are confluent over the 
sides and broadly each side of the median suture, and form a border within the
