 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, II and 12. These hairs are either dirty white with a few black 

 ones interspersed, or of a more uniform reddish-brown. They spring 

 in bundles from around large warts situated as follows on each joint : 

 4 which are black and dorsal, arranged in a trapezoid, the anterior 

 pair being the smaller ; and 4 which are orange 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. " 



This insect is only too well known as the Fall Web-worm. The 

 larva are hatched about the month of July ; they live in company 

 under a web.
