the middle, and one near the inner angle of the wing; in one specimen, the 

 inner two-thirds of the wing is paler, somewhat whitish, thus approaching 

 the normal color of nyssaria. The three specimens arc from Detroit, Mich. 

 (Swartz, Mas. Comp. Zool.), Brewster's, N. Y. (Grote), and from Dallas, 

 Tex. (Boll). 



Walker's nepiasaria (plate 13, fig. 42) is a small individual, with the 

 middle of the fore wings yellowish atid the remainder pinkish; hind wings 

 yellow, outer third pinkish. 



A fourth variety is represented by fig. 38, of which the following is a descrip- 

 tion: 2 9. — Cinereous, with an obscure lilac tinge. Palpi stout, long, porrect, 

 tipped with black. Head, body, and wings at base concolorous. On the fore 

 wings, a broad, zigzag, brown line, pointed acutely four times on the nervules, 

 the last time on the costa, shaded within on the costa; internal margin 

 strigated with black more than the rest of the wing; middle of the wing 

 clearer than the base ; outer line very large, elongated ; angle obtuse, going 

 much nearer the outer edge than usual; apex rounded, not acute as usual; 

 line fuscous; beyond fawn-color, with a lilac tinge; a costal dark streak near 

 the apex, which is falcate, produced a little more than usual, well excavated 

 beneath; angle distinct in I he middle, rounded, below well excavated; discal 

 dot indistinct on both wings. Hind wings same as the fore wings, deeply 

 excavated on each side of the mesial, prominent, rounded angle. Beneath, 

 the body is fusco-cinereous ; wings ochreous, with fuscous strigse, margin 

 of the wing violaceous, except on the fore wing toward the costa, where it 

 becomes ochreous, and directly on the costa whitish-cinereous. 



Length of the body, 0.40; of fore wing, 0.55 inch. 



Natick, August 2 (Stratton) ; Illinois (Clemens). 



This variety is easily known by the cinereous body, with the outer 

 margin fawn-colored, which becomes violaceous on the under side, and 

 without the usual dark, violaceous spots on the margin near the inner angle; 

 beneath, more distinctly ochreous than usual ; the apex is falcate, as usual, 

 and the mesial prominence well marked ; the angle of the outer line is also 

 more produced, and ends in an obtuse, rounded point. 



This species is so exceedingly variable that no one can be blamed for 

 regarding the more aberrant forms as good species, if they have but a single 

 specimen; but, with the excellent material I have had, I have little hesita- 

 tion in regarding the synonymy given above as approximately correct, and
