the climbing bittersweet ( Ce/asfrus scan dens). . A few larvae were 
taken on bittersweet leaves, also. As before stated, the larvae 
evidently remain in one location ; that is, upon the same leaf for 
quite a period of time ; but when disturbed they move about, and 
frequently in attempting to capture them they would make a 
sudden leap, as all of this family of insects are in the habit of 
doing. 
August 7 th, exuviae were found abundantly upon wild plum 
leaves, and a few on leaves of wild grape. From these observa- 
tions it is evident that this species has quite a variety of food 
plants, the larvae and exuviae having been found on climbing 
bittersweet, dogwood, plum, grape, prickly ash, red oak and 
liawthorne, most abundantly on the first mentioned and in less 
numbers on the others, in the order named. 
Several visits were made to this particular hedge, and I was 
always rewarded by the capture of several adults and an occa- 
sional larva ; but search upon other similar hedges of the vicinity 
failed to yield a single larva or show evidences of their having 
been there, although an occasional adult was taken. 
DESCRIPTION OK LARVA. 
Length 45 mm.; width, 2.5 111m.; somewhat depressed, only about one- 
tliird as thick dorso-ventrally as 1 terally ; a very pale green, even to 
whitish ; head narrow, projecting slightly beyond eyes, rounded in front, 
above covered by the pronotum ; frons broad, three carinse, margin extend- 
ing laterally slightly in front of eyes ; eyes pinkish brown ; ocelli wanting; 
antennae cylindrical, first segment shorter than the second, bristle brown, 
enlarged at base ; pronotum produced forward, covering the head, deeply 
emarginate behind, the angle rounded ; whole pronotum covered with black 
pustules having lighter centers, or many entirely black ; mesonotum has two 
convex pustule covered areas, one on each side between median line and 
wing pads ; a median groove extends the length of thorax, most pronounced 
on the mesothorax ; wing pads extending to the third abdominal segment ; 
each fore wing pad has two triangular black patches near base and a rounded 
black patch near apex ; a large black patch on hind wing pad ; these black 
patches are not always prominent, anil vary in size, shape and position ; legs 
pale green ; posterior tibia; with three spines on outer edge and a large one 
at apex, also six smaller apical spines ; tarsi three-jointed ; feet brownish, 
and the tibial spines tipped with brown ; abdomen covered with a white 
filamentous waxy secretion, which at the tip of abdomen is in tufts ; this 
secretion is produced in such abundance as to entirely cover the insect when 
feeding upon the surface of a leaf, and thus serves as a protection on account 
of its resemblance to a bunch of spider web or a tuft of cottony hairs upon 
the leaf.
