set£e, shorter than the white hairs of subventral row; but soon the 
tubercles elongate, forming the pale basal portion of the spine. Skin 
smooth, slightly shining. The larva feeds in this stage. Length 1.2 
to 1.8 mm. 
Stage II. _Instead of the spines of the subdorsal row are now 
present on joints 4 to 12 a series of laterally extended, short, conic, 
fleshy appendages, projecting about half their length beyond the sides; 
those on joints 7, 9 and 11 much shorter than the others, which are of 
equal length; all densely covered with coarse, smooth, pale spines. 
The other setae, namely all those of joint 3, the lateral row and those on 
joint 13 form small pale tubercles, with a single hair, inconspicuous, 
being obscured by the appendages of the subdorsal row. Color dead- 
leaf brown, the tips of the appendages whitish, the outline evenly 
fringed by the white spines. Dorsal space narrow, clothed by a few 
small dark setae, On the sides, owing to the broad attachment of the 
subdorsal appendages, the lateral space occupies but one-third, the sub- 
ventral space two-thirds of the area, both perpendicular. Lateral area 
brown; subventral dull whitish. Length 1.8 to 2.5 mm. 
Stage ///—(Plate VIII, fig. 3) Elliptical, the back flat, produced 
by laterally extended appendages; side area small. Appendages as be¬ 
fore, but longer, each slightly constricted near the base, rather sparsely 
covered with stiff, pale setae, arising from conical bases. Yellowish- 
brown, a double blackish spot on the top of each appendage, the tips 
pale; subventral edge white. A tuft of fine short hairs in the center of 
each segment of dorsal space. Lateral tubercles with single seta; sub¬ 
ventral setae double. Head testaceous, the eye black. Length 2.5 to 
3.5 mm. 
Stage IV. _Appearance as before, but the horns are more densely 
covered with the sharp stiff, pale-yellowish setae. The basal portion of 
each horn is divided off by a constriction, approximately bisecting the 
short horns. The horn on joint n is proportionately longer than be¬ 
fore ; otherwise as in the previous stage. Color brown, fringed by the 
pale spines, the long horns shaded in a darker tint. Length 3.5 to 
5 mm. 
Stage V —(Plate VIII, fig. 4) The discrepancy in the sizes of the 
horns has increased. Those on joints 6 , 8 and 10 are elongated, those 
on joints 7 and 9 remain short and that on joint 11 is about as long as 
the one on joint 12. The lateral tubercles are almost invisible, being 
covered up by the subdorsal ones; but they are furnished with a crown 
of stiff hairs besides the central 'seta. Color brown, the horns darker
