above, broadly red centrally, the horns bright red. Sides blackish 
purple, a broad lateral line and the subventral edge red; a narrow 
whitish line above and below the lateral red line, the upper broken. A 
broad pale stigmatal line. Lateral horns red. Spines pale with black 
tips ; skin clear granular. Small patches of caltropes are present on the 
tips of the lateral horns on joints 6 to 12 in eight stage larvae. Length, 
10.5 to 16 mm. 
Stage VIII. —(Plate II, Fig. 3) Shape as described. The blackish 
lines are now still narrower and appear plainly as lines. Dorsal space 
bluish white with four black lines, waved and confluent opposite the 
large horns. The rest of the ground color pale yellow, the horns fiery 
red. Red bands along subdorsal and lateral ridges, in the middle of 
lateral space and along subventral edge. Sides with four black lines, 
subconfluent in pairs; subventral area with two black lines. Joint 2 
purplish ; venter honey brown. The red side-band is partly cut by the 
pale, dark centered, depressed spaces (4); spaces (1) small, paired, 
dark. Skin clear granular (Plate II, Figs. 4 and 6). Caltrope patches 
(Plate II, Fig. 10) present on the lateral horns of joints 6 to 12 and the 
subdorsal of joint 13. Spines enlarged at base, pale with black tips 
(Plate II, Fig. 8). Length, 16 to 22 mm. 
In the yellow form all the red markings are bright yellow. It did 
not come under observation in the early stages, but doubtless differs 
from this only in the absence of red, beginning with stage IV. The 
yellow form seems the more generalized of the two. 
Food-plants .—The larvae feed on various kinds of low brush. I 
have notes of finding them on wild cherry, oak, hickory and bayberry.
