1914] Pupe of Ceratocampide and Hemileucide 283 
This genus contains two species, bicolor, found in the 
Mississippi Valley and the Southern Atlantic states, and 
bisecta, found in the Ohio Valley. The species may be sepa- 
rated as follows: 
A. Antennae with prominent spines; spines of cephalic margins of abdominal 
segments 5 to 7 larger than those on the other segments........ bicolor 
AA. Antennae without prominent spines; spines on the cephalic margins of 
abdominal segments 5 to 7 not larger than those on the other seg-

Adelocephala bicolor Harris. Color dark reddish brown; 
head, thorax and appendages finely spinose; abdominal seg- 
ments both punctate and finely spinose; antennae with the 
length four times the greatest width, strongly convex, with 
two rows of spines, the outer row, large, prominent and curved 
caudad, the mesal row minute; face parts with an elevated 
spiny ridge on each side extending cephalad from the proximo- 
lateral angles of the labrum to the proximal end of each antenna, 
bearing a prominent spine near the cephalic end and a smaller 
one half way between this and the labrum; epicranial area with 
two prominent spines on each side the meson at the proximal 
end of each antenna; sculptured eye-piece with a prominent 
spiny tubercule; labrum usually six-sided, broader than long, 
maxillae with length and greatest width equal, each half 
quadrilateral, the length measured on meson, one-fourth the 
length of the wings; first and second pair of legs elevated and 
convex; cephalic portion of prothorax prominently elevated 
on meson sloping gradually to lateral margins, the larger 
spines on the elevation pointing dorsad, a slight elevation 
with larger spines near the meson at caudal margin on each 
side the meson; prothoracic spiracles with cephalic margins 
arcuate; mesothorax with a slightly elevated ridge each side the 
meson with at least two bifid spines, a prominent spine at the: 
base of each wing and another half-way between these spines 
and the meson; abdominal segments 1 to 4 with rows of minute 
spines along the cephalic and caudal margins of the exposed 
portion; abdominal segments 5 to 7 having the cephalic margins. 
dorsad between the spiracles with sharp transverse ridges and 
distinct furrows between, ventrad with large circular punctures, 
the margins produced into flange-like ridges set with broad, 
flat, erect spines, many of them bifid; the caudal margins of 
abdominal segments 5 to 7 with similar but very much smaller 
spines, the spines of both cephalic and caudal rows much smaller
