NORTH AMERICAN LEPIDOPTERA. 145 



This species is easily distinguished by the characters above pointed 

 out. It is not uncommon, becoming more rare, however, north- 

 wardly. 



The side pieces of the % are moderately long and broad, some- 

 what curved, the tip broadly rounded ; the clasper is rather short, 

 stout, narrowing rather rapidly to a point, somewhat curved. 



There is little variation in this species save in the distinctness of 

 the shades and in the amount of rosy shading iu the primaries. The 

 green of the primaries fades readily into a sordid luteous. 



The larva being of some economic importance has been frequently 

 figured and described. Harris first gave a tolerably complete life 

 history and figures of this species, and Prof. Riley has also figured 

 and described the various stages.

 Head, thorax and primaries above grayish fawn, or red ash color, with the 

 maculation and shadings brown. Palpi, except at tip, brown. Patagise rich deep 

 brown, forming a somewhat trigonate patch on each side. Abdomen somewhat 

 darker dorsally, laterally near base with a roseate tint; segments narrowly edged 

 with white posteriorly. Primaries with a brown dot near base; a quadrate deep 

 brown patch at middle of iuuer margin : a small, trigonate patch of the same 

 color just before anal angle, aud a larger, also trigonate, patch before apex ; a 

 dusky shade from the middle of costal margin outward and downwardly as in 

 pandorus ; terminal space dusky. The transverse lines are as iu jjawrfortts. but 

 more distinct. Secondaries pink, with a reddish ash colored outer border, which 

 has a row of elongate deep brown spots along its inner edge not clearly defined 

 in the basal half of the series, and there is a diffuse, dark reddish spot above the 

 anal angle. Beneath, primaries rosy red, with a broad ash colored outer margin, 

 which is inwardly dentate, and two parallel, somewhat rivulous, transverse, 

 deeper brown lines. Secondaries powdery, with two parallel transverse lines. 

 Expanse 3.75 — 4.25 inches ; 95 — 106 mm. 



Hab. — Canada ; United States from Atlantic to Pacific.
