has a dark patch on the posterior part of the dorsum. Head pale reddish, 

 the same shade as the red ground color, marked with irregular longitu- 

 dinal rows of white dots ; feet pale red ; ventre pale yellow with black 

 centres to the joints, those at the anterior and posterior parts of the body 

 small. At this time there is a distinct fringe of fleshy appendages on 

 the sides. 



Mature Larva. — Length 2.75 inches ; cylindrical, tapering slightly to 

 either extremity, with short lateral fringe. Marked as at the beginning 

 of the period with seven longitudinal stripes from stigmata to stigmata, 

 the lower dark one stigmatal, below this the space to the fringe the same 

 color as the dorsal stripe, making the nine stripes mentioned before. 

 The stripes are very nearly the same color, the only difference being that 

 the dark ones have a little more of the black mottling than the pale ones ; 

 the stripes are divided by narrower stripes or broad lines of the ground 

 color, which is dull, pale, smoky red. The thoracic joints are a little 

 darker than the others. Piliferous spots pale nankeen, the dorsal tipped 

 with orange ; the space between the posterior dorsals on joint 9 black, 

 only a little elevated; the posterior pair on joint 12 about three times as 

 large as the others ; each tipped with a very short black hair. Head, 

 the ground color striped with reddish white that consists of transversely 

 elongated dots ; feet the ground color ; fringe white ; ventre pale yellow

 abdominal joints moderately punctured, anterior part of each a little cor- 

 rugated ; head moderately rounded. Color chestnut brown, covered with 

 a white powder as is usual. Duration of this period from 30 to 32 days. 



In pupating, the larva fastened leaves together with silk, slightly 

 lining the interior, and into this thin lining the cremaster was fastened. 



Food plant hickory. 



The eggs from which the larva? from which these notes were taken

 being fifty-eight of them in a mass, laid so that they overlapped each

 shells of other eggs in the crevices of hickory bark deposited in the
