spined, but the spines all simple, the seta from a bare cone as before. 
The coarse seta; on the horns still present, rather less in number than be¬ 
fore, and the fine branched hairs are more numerous. The long horns 
bear six kinds of hairs in this stage: (i) the primitive setae, (2) the 
smooth pale setae, (3) the long pale spinulated hairs, (4) the fine felted 
secondary hairs, (5) the club-shaped black hairs and (6) the fine spines 
on the tip. Length 10 to 13.5 mm. 
Stage IX .—(Plate VIII, figs. 5, 6 and 7) Shape as described above. 
The third, fifth and seventh pairs of appendages longest, second and eighth 
next, first, fourth, sixth and ninth short. The side view (Plate VIII, fig. 
6) shows how these may be variously elevated by the larva. The body 
is sparsely clothed with fine dark setae (Plate VIII, fig. 15), the appen¬ 
dages both of subdorsal and lateral rows covered only with the fine 
branched secondary hairs (Plate VIII, fig. n). The primitive setae re¬ 
main and at the tips of subdorsal horns a circle of very short black 
branched hairs (Plate VIII, fig. 10). These are absent on the side horns 
(Plate VIII, fig. 8). The black club-shaped hairs also remain, irregu¬ 
larly scattered toward the tips of the long horns; but all of the stiff pale 
setae are absent. Any of the appendages of either row may be detached 
by slight force. They leave a bare area, and the subdorsal ones show a 
double attachment (Plate VIII, fig. 9) corresponding to setae i and ii. 
The larva is quite uniformly colored, varying from tan color to purplish 
brown. The subventral edge is usually broadly white and the sides and 
under sides of the horns darker than the upper surface. The fine hairs 
on the horns are so dense and closely felted that they give the shape to 
the appendages as shown in the figures 5, 6 and 7. Length of larva 
13.5 to 22 mm. 
Cocoon.— As usual except that as all the tubercles are shed at the time 
of spinning, they remain on the outside of the structure and give it a 
characteristic appearance. 
Food-plants. _Various low shrubs and the lower branches of trees. 
I have records of oak, chestnut, sassafras, dogwood and ash.
