THIRD ANNUAL REPORT OF 



From the foregoing account it will at once be seen how widely 

 this Pall Web worm really differs from the Tent-caterpillars. It hi- 

 bernates in the pupa state, they in the egg state ; it appears mostly 



in the fall, they mostly in the &pi 



its moth is pure white, theirs 



reddish brown ; its eggs are deposited on a leaf, and hatch before the 

 leaf falls, theirs are deposited around a twig, because they have to- 

 pass the winter and would get lost with the leaves if deposited upon 

 them; it feeds- solely on the parenchyma of the leaf under its web, 

 they devour the whole leaf outside of their tent ; and on account of 

 these differences, we cannot employ the preventive measures against 

 it which we take against them. 



REMEDIES. 



As, therefore, nothing can be done to materially affect this insect 

 during the winter, we must do all the fighting when the worms first 

 hatch. Their web soon betrays them, and the twig or branch con- 

 taining it may be pruned off in the same manner described for the 

 Tent-caterpillars. As the worms are always under the tent, the ope- 

 ration in this case can be performed at any time of the day without 

 the risk of missing an} r wanderers. 



IlYrHANTRiA textor — Larva — (Fig. 55, a) GjonncUcolor greenish yellow. Dor3um relvety-- 

 black, with a narrow median pale line on thoracic joints. Sides speckled with black, except along 

 subdorsal and stigmatal lines, where longitudinal yellow patches are left clear. Venter dusky or 

 smoky-brown. Head shiny black with labrum and antennae white. Thoracic legs black ; prolegs 

 long and narrow, smoky-black with faint orange extremities. Covered with' long straight hairs, 

 longest on joints 2, 3, 11 and 12. These hairs are either dirty white- with a few black ones inter- 

 spersed, or of a more nniform reddish-brown. They spring in bundles from around large warta 

 situated as follows on each joint ; 4 which are black and dorsal, arranged in a trapezoid, the ante- 

 rior pair being the smaller ; and four which are orang-e on each side, and arranged in a transverse 

 row in the middle of the joint. Stigmata light yellow. Average length, 1.10 inches. 



Varies considerably, in some the black predominating, in others the yellow. Those found on 

 hickories are usually the darkest. When newly hatched it is pale yellow with two longitudinal 

 rows of black marks and a black head. 



Described from numerous specimens. 



THE BLUE-SPANGLED PEACH VIOmiL—OalUmorpha fulvicosta,

(Lepitloptera, Arctiidic.) 



In examining apple trees, but more especially peach trees, dur-

ing winter or early spring, we 

 often come across little black 

 worms, covered with short, 

 sti'ff, sprangling hairs, and stud- 

 ded with minute blue spots, 

 sheltering under the loose 

 bark. As soon as the leaves 

 put out, these worms issue 

 from their winter retreat and 

 commence feeding. They
