Jieverlv, i\Iass., August 2H (Burgess); Boston, Jlass. (Morrison); New 

 Jersey (.Sa(dis); Easton, I'a. (C'lemens, Stultz); Dallas, Tex., in March, not 

 rare, about .liiniperus Virgiiikinu, and also in October, June IG (Boll, Mus. 

 Peab. Acad. Sc). 



I'his species dilfers from /'. (itrofuvcialit in the liroader wings and the 

 usually nioic siniuite and angled outer line and the curved inner line. The 

 species is nion' nearly related to the latter than to any other. My Pennsyl- 

 vanian male is much smaller than the Texan males or the females, and the 

 two lines are more curved and aijproxiniale. The Texan male is much larger 

 than the Pemisylvanian one, and the two lines on the fore wings are much 

 farther apart, while the basal line is straight, not curved outward. In the 

 Texan male, also, the costa of the fore wing is slightly curved inward, the 

 a[ie\ ix'ing much rounded, the shape of the wing being much as in the 

 ]M\ropean Ei(ho/ia iiiiirinanii. 



As the s|iecimeu desci-ibed as I'Jiasianc excurvala dilfers in some respects 

 from the eastern examples, I apjiend the original description: — 



1 S . — In the onllinc! of the wings, the antennuc, and in other structural 

 features, this species is closely allied to P. ty'ifasclatd Pack., but the markings 

 are quite diflcrent. Body and wings deep mouse-gray. Fore wing.s with 

 inner line not curved as usual, but straight, in its course oblique, ending 

 nearly twice as far on the costa li-om the base of the wing as on the inner 

 edge; the line is black, with an inner dusky shadf.' acconqianying it. Middle 

 lint! not curved exactly 'paralh'l to the inner, blackish and passing very near 

 tiie oblong discal dot. ()uter line bla(d<, rather obli(pie, curved ontwai'd a 

 good deal just below the costa oppositi' Ihr discal dot. A dusky shade not 

 much wider than the line itself accompanies the liiu', and is connected with 

 a broad costal spot nfulway betwe(>n the outer line and the apex of the wing. 

 A peculiar whitish, very bioad, dilfuse, irregular .shade starts from tlie apex, 

 where it is narrow, and ends en the anal angle of the wing. Hind wings
