the climbing bittersweet ( Celastrus scandens). 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 lia1)it of 

 doing. 



August 7th, exuvicC were found abundantly upon wild jilum 

 leaves, and a few on leaves of wild grape. From these observa- 

 tions it is e\-ident that this species has quite a \-ariety of food 

 plants, the larvcC and exuviae having been found on climbing 

 bittersweet, dogwood, plum, grape, prickly ash, red oak and 

 hawthorne, 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 3'ield a single larva or show evidences of their having 

 Ijeen there, although an occasional adult was taken. 



DESCRIPTIOX OF LARVA. 



Length 4 5 nmi.; width, 2.5 mm.; somewhat depres.sed, only aljout one- 

 third as thiik dor.so-ventrally as 1 Icrally ; a very pale green, even to 

 whitish ; head narrow, projecting slightly beyond eyes, ronnded in front, 

 above covered by the pronotinn ; frons broad, three carinie, margin extend- 

 ing laterally slightly in front of eyes ; eyes pinkish brown ; ocelli wanting; 

 antennae cylindrical, iir.st .segment shorter than the second, bristle brown, 

 enlarged at base ; pronotum produced forward, covering the head, deeply 

 emarginate behind, the angle ronnded ; whole pronotum covered with l)lack 

 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 tlie third abdominal segment ; 

 each fore wing pad has two triangidar 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, and vary in size, shape and position ; legs 

 pale green ; posterior tibite with three spines on outer edge and a large one 

 at apex, also six smaller apical spines ; tar.si three-jointed ; feet brownish, 

 and the tibial spines tipped with brown ; abdomen covered with a white 

 filamentous waxy secretion, which at the tip of alxlomen 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 re.semblance to a bunch of spider web or a tuft of cottonv hairs upon 

 the leaf.
