ClTHERONIA REGALIS, Fabl\ 
The larva is of a green color with a yellowish cast and smooth. 
There are on the first segment two straight, serrate, orange colored 
horns and four small black ones, each with a yellow base. The 
second segment has eight spiny horns, four large orange colored 
tipped with black, and four small and black, the larger ones curved 
backward; on the front of the segment are two large black spots. 
The third segment has the horns arranged as in the second, with 
the black spots much larger extending to near the margin of the second. 
The remaining segments each have six black compound spines, ex¬ 
cept the eleventh, which has but five, and the twelfth, which has 
seven, the number varying on the last two; the spines arise from a 
somewhat elevated sky-blue patch, which sometimes forms a distinct 
transverse ridge, and are slanted backward. A lateral row of large 
cream colored oblique spots on the anterior part of each segment 
from four to eleven inclusive. Head and legs orange colored, the 
true legs with black tips; pro-legs with a black mark extending up¬ 
ward on the body. Length from five to six inches. 
It feeds on the Hickory, Black Walnut, Butternut, Sumach and 
Persimmon.

branches; they are sheltered by this tent from the sun and incle¬ 
ment weather when not feeding, a large number of them living to¬ 
gether. They come out twice a day to feed, once in the forenoon 
and once in the afternoon. 
When first hatched the worms measure less than one-tenth of an 
inch in length and are about the diameter of a common sized pin, 
tapering slightly from the head backward, general color black, feet
