the body consist of conical tubercles, each with a short spine, tubercles 
one and two on joints 6 and 7 larger than the others. Cervical shield 
colored like the head; liorns red-brown, their tubercles paler; body green, 
a broad red-brown dorsal band, very narro-w and nearly obsolete on 
joints 3 and 4, widening into an elliptical patch on joints 5-11 and enclos- 
ing on joints 7 (posteriorly), 8, 9, and 10 (anteriorly) a patch of the 
ground color, faintly bisected by a brown dorsal line. On joints 12 ami 
13 the band is faint, only tinging these segments. Tails red-brown, 
twice annulated with green ; length 4.5 mm. Five days after the molt, the 
following description was made: Body highest at joint 3 posteriorly: a 
red-brown dorsal band begins widely on joint 2, covering the horns, 
narrows to a line on joint 4, rapidly widens and reaches the spiracle on 
joint 8 ; then narrows to a line on joint 12 and, widening again, covers the 
anal plate. It is edged with yellow and contains, on joints G-'J, an ocher- 
ous yellow patch which is broken by a narrow, brown, dorsal line and 
the brown tubercles. The sides of the body are clear green, dotted with 
yellow. The anterior annulation of the tails is yellowish, the posterior 
one yellow. Venter, especially posteriorly, whitish. Joint 2 edged Avith 
yellow at the sides anteriorly. 
Fourth stage. — Head partly retracted beneath joint 2, shaped as before 
and colored much the same, but yellow on the sides posteriorly ; mouth 
parts whitish; a few piliferous tubercles; width 1.9 mm. Prothoracic 
horns thick, pointing forward, covered with piliferous tubercles. The 
tubercles on the body are short, but bear stiff black setae. They are 
concolorous with the markings except tubercles one and two on joints G, 
7, 10, and 11 which are larger than the rest and blackish. Tails covered 
with spines which arise from enlarged bases. Body marked as in the last 
part of the previous stage except that the paler patcii on joints 6-9 is more 
brownish, and the anal plate is tinged with yellowish. Tails 5 mm. long, 
the extensile threads black, but white at base and middle. 
Two days after the molt the markings had more the appearance of the 
last stage, the central patch (that part of the band on joints 4-11) being 
slightly indented along its edges in each segmental incisure. 
Fifth stage. — Head partly retracted below joint 2, rounded, higher than 
wide; clypeus small, depressed; i-ed-brown, the upper two thirds, except 
the clypeus, covered with little, round, yellowish dots, but leaving an 
obscure line of the ground color on each side of the median suture; yellow 
at the sides posteriorly; mouth parts pale, jaws brown, antennae yel- 
lowish; width 3 mm. Cervical shield large, horns short, rounded, 
smooth, without tubercles but sparsely punctured. Piliferous dots 
absent, the setae short and tine. Tails spinose, turned up at the end. 
Body pale yellow, thickly sprinkled with little whitish and brownish 
dots, not very distinct; spiracles pale brown; a subventral row of brown 
spots corresponding to legs on the posterior apodal segments, and a 
medio-ventral line posteriorly. Dorsal band ferruginous brown, consist- 
ing of three connected patches; the first triangular, covering the horns, 
marked like the head on joint 2 and narrowing to a line at the elevation
