NORTH AMERICAN LEPIDOPTERA. 187 



what beyond the middle of costa is the inception of a second band, cxtendin'r, 

 however, but a short distance toward the disc. An apical oblique black streak 

 and short, rather heavy black dashes between most of the veins. Fringes pale, 

 cut with dark gray. Secondaries brownish gray, darker outwardly. Expands 

 3 inches ; 75 mm. 



This description is made from a specimen of puuistri (European) 

 which agrees perfectly with Mr. Strecker's figure. Mr. Htrecker's 

 description is comparative wholly. He says : " Male expands three 

 inches. Upper surface in color and ornamentation same as the Eu- 

 ropean S. Pinastrl L., with this exception — that the latter has two 

 broad, transverse brown bands on primaries, the outermost of which 

 is entirely wanting in the present insect, and the innermost is quite 

 narrow and darker in color than in Finastrl. Under surface bi'owu- 

 ish gray, faint traces of a mesial band on secondaries. In Pinastrl. 

 are the marginal parts of primaries a little paler and more ashen 

 than the rest of the wing ; in this species there is no perceptible 

 change in the coloration. 



" Female expands 31 inches. 



" Head and body same color as the male, destitute of all markings 

 save a faint apical line and the obscure streaks in cells between the 

 median nervules near the median nervure. 



" Under surface uniform dull grayish brown. 



" Described from one S and one $ example. The former was 

 captured in Canada, and was received by me from Mr. Reakirt; the 

 female I took sitting on a fence near some pine woods a mile from 

 Reading, Pa. I have never seen any others. Both examples are in 

 good condition, though the female is a little w'orn ; they seem to me 

 to be an intermediate i'ovm between Sequokt and Pinastrl, though 

 very close to the latter. 



" Some years ago in the month of October, crawling among the 

 dead pine leaves in this same piece of woods, I found two larvre 

 which belonged to some insect of this group, perhaps to this species. 

 My notes say : ' Not quite three inches long, rather slender, head 

 yellow striped with red ; body reddish, surrounded with many trans- 

 verse fine black lines ; a brown stripe on back from head to anal 

 horn, this stripe lined with white on both sides ; on sides alternate 

 bands or lines of green and yellow, green predominating from head 

 to last segment (save one) ; caudal horn dark reddish brown ; first 

 few spiracles white, the others ringed with red and black ; from base 

 of anal horn to end of anal segment a reddish brown dorsal line.' " 



The larviie were not carried to maturity.
