ings. The third stage is characterized by yellow incisures. In 

 the fourth stage the head and the body beneath are quite flat- 

 tened, the lateral edge being ridged below the spiracles. 



" The full-grown larva is a dull dirty green mottled with green- 

 ish ocherous. The head is comparatively small, and the first seg- 

 ment is about equal the width, the remaining segments gradually 

 increasing in size. The thoracic feet have the bases considerably 

 swollen and ringed with ocherous. The pair of abdominal and 

 anal legs are chocolate brown. Over the body are scattered 

 irregularly small, elevated, pale yellowish spots, especially on 

 the last three segments, which are conspicuously mottled. The 

 cervical shield is dirty chocolate brown; on the second to tenth 

 segments inclusive, are four minute bkick tuberculate spots; the 

 fourth and fifth segments have an additional pair of spots. The 

 transverse ridge on the fifth is very prominent, as is also the 

 one on the underside of the sixth segment and the one on the 

 eighth segment, and the two black tuberculate spots on the 

 dorsum of the eleventh segment. Underside of body same as 

 above, except the last three segments pale whitish-green. Anal 

 plates tinged with lilac. Length no mm." (Beutenmueller) 



The pinkish white pupa is covered with a mealy substance, 

 the extremities of the segments roughened, the interspaces being 

 semitransparent and yellowish. The change to the pupa occurs 

 in an oval, elongated, whitish cocoon open at each end. 



The parent moth (plate 8, figure i) is a delicate ocher yellow- 

 ish insect variably marked with purplish and reddish brown, 

 especially at the extremities of the wings, the anterior pair with 

 a conspicuous, almost hooked lobe near the middle. The male, 

 with its pectinate antenna, has a wing spread of about one and 

 five-eighth inches, while the larger, stouter bodied female has 

 slender antennae and a wing spread of about two and one-eighth 

 inches. 



Life history, Oviposition occurs in September and October, 

 individual females depositing from five hundred to six hundred 

 eggs. These latter hatch the following May or June, the larvae 

 attaining full growth from the latter part of July till the end of 

 September. The pupal stage lasts from eighteen to twenty days, 

 adults flying from early August until the last of October. There 

 are specimens in the Lintner collection taken at Keene Valley, 

 N. Y., August 7, 1894.
