ed outwardly. On the margin, between the nervures, are brownish 

 lunules. Fringe concolorous. Secondaries, sordid white, margin 

 broadly dusky, as is also the lunate discal spot. Beneath, entirely 

 sordid white, with dusky shade in centre of the primaries, and the 

 margins sometimes dusky. Thorax ochreous, with pinkish scales. 

 Abdomen, sordid white, with blackish scales. Exp. wings, 1.50 

 inch. Several examples. <^. ?. Colorado, Utah, Arizona, Flor- 

 ida. Types Coll. B. Neumoegen, Hy. Edwards. 



It is possible that this and S. Inepta, may prove to be ex- 

 treme forms of the same species. 



HOMOPTERA RUBI, n. sp. 



S. General color, stone drab, lighter, and less brown than 

 any other species known to me. Primaries with the t. a. line 

 broad, oblique, approaching very closely to the base of the wing, 

 rich brown, narrowly bordered with a darker shade. Median 

 space sparingly dotted with blackish atoms. Reniform, sublu- 

 nate, edged with dark brown. The t. p. line is very strongly 

 marked, showing in vivid contrast with the pale color of the 

 wings. It is rich brown, edged with a darker shade, with a deep 

 tooth in the middle, joined to another brownish shade, which 

 reaches the margin of the wing. Secondaries with a rather 

 broad and distinct subrriedian band, brown, edged as in the supe- 

 rior wings, with darker shade, and several waved bands of dark 

 drab both at the outer margin and towards the base. Thorax 

 and abdomen concolorous, with the collar and thoracic tufts 

 flecked with brown. Underside wholly of the color of the upper, 

 with faint median double line on both wings, and a discal spot 

 on secondaries, brown. The margins are also brown, and the 

 whole of the wings thickly dotted with blackish atoms. 



?. Resembling the S, but with the brown bands of the 

 upper surface almost obsolete, the insect being thus almost of 

 uniform color. Exp. wings, 1.55-inch.

Typ. Coll. Hy. Edwards. 



This species is most nearly allied to H. Atrilineata. Harvey, 

 but differs from it by its large size, paler color, greater angularity 

 of the t. p. line, and by the generally heavier markings. 



A NEW SPECIES OF ARCTIA, FROM COLORADO.

 black spot on the vertex, between the antennae, which are mod- 

 erate, bi-serrate, of blackish color, but whitish at tips of pectina- 

 tions. Thorax equally creamy white, with two prothoracic and
