and absent in others near by. Though not gregarious many are often 
found on the same bush. They are low feeders, not occurring on trees 
to any extent. 
The eggs are laid during July and the larvae mature toward the 
middle of September. They remain on the under sides of the leaves in 
spite of their very conspicuous coloration. The effect of a touch of 
their spines is about the same as that of Sibine stimulea . The larvae 
have eight stages, occasionally nine. Two examples bred from eggs of 
the same moth varied in this respect. They do not feed in stage I, 
which is rapidly passed through. 
I am indebted to Miss Morton for obtaining for me the eggs from 
moths bred from larvae part of which I collected and part obtained from 
Mr. Doll. 
Criticism of Previous Descriptions. 
All of the references given are to figures or descriptions of the ma¬ 
ture larva, none of them going into structural details. The two best are 
that of Professor French (1885) and my own (1894). . I notice nothing 
important of a positive nature to criticize except that in Prof. French s 
account the segments from which the horns are said to arise are not 
quite accurately numbered. 
Description of the Several Stages in Detail. 
Egg. _Singly, or in small groups, slightly imbricated. Elliptical, 
flattened, translucent pale ocher yellow on glass, 1.5 x .9 mm.; reticu¬ 
lations obscure, visible only in a strong light, rounded hexagonal, 
nearly linear, somewhat irregular. No special characters. They hatch 
in nine days. 
St a g e /.—(Plate II, Fig. 1.) Not different in structure from Euclea 
delphitiii , the horns proportioned the same, each with three setee with 
slightly swollen tips. Color rather dark yellow, shining, the long 
horns whitish. Segments well marked ; skin smooth. Shape as usual, 
elongate, squarish, the horns low conical, prominent, their bases con¬ 
tiguous. Length 1.1 mm. d he larvae do not feed in this stage. 
Stage //.—Subdorsal horns on joints 3, 4, 5, 8, n and 12 large, 
rounded; the rest, small, all furnished with stinging spines; the short 
subdorsals (joints 6, 7, 9, to) bear only one spine and are crowded up 
adjacent to the next large horn. Spines pale, black tipped. Ridges 
whitish, but dorsal and lateral spaces faintly shaded with dull red; 
horns pale. Dorsal depressed spaces (1) cleft-like with paired dots.. In 
shape the larva is thickest through joints 4-5, the outline elliptical;
