lines forming broad, rather even white bands in the female, becoming more diffuse 

 inwardly iu the male. S.t. line whitish, very irregular, tending to become lost medi- 

 ally, a little emphasized by brown preceding scales in some specimens; a patch of 

 golden brown scales at the apex. A series of black terminal dots, fringes obscurely 

 cut with pale. Orbicular a small black dot, Reniform a small black crescent at 

 the inner edge of the white band forming the t.p. line. Secondaries smoky gray 

 with a diffuse whitish median band, more distinct in the male, in which a dusky lu- 

 nate discal mark is more or less obvious. Beneath, primaries smoky at base, becom- 

 ing paler outwardly until they are white before a distinct broad, defined blackish s.t. 

 band, beyond which the wing is again pale. There is a small black discal lunule. 

 Secondaries whitish, with a narrow extra-basal dark band, a broader, blackish sub- 

 terminal band, and a black discal lunate mark.

One male and two females, in fair condition. I have been inclined to 

 regard these as forms of crustaria INIorr. ; but the receipt of quite a series 

 of the latter shows them to be distinct. The vestiture is smoother through- 

 out, and, while the maculation is almost the same, there is none of the 

 bright coloring or sharp contrast of the older species. The armature of 

 the fore tibia is also somewhat different, forming distinct outer and inner 

 claws, instead of a long inner claw wuth a marked outer angle of the flat 

 corneous tip. 



Pseudacontia louisa nov. sp. 



Head and thorax rich yellow-brown mottled with creamy white and black scales; 

 abdomen yellowish. Primaries creamy yellowish white marked and mottled with 

 brown and black. Basal space brown-powdered, so that the pale ground is only 

 just discernible; the basal line geminate, blackish, included space of the ground- 

 color. T.a. line a broad band of the basal creamy tint, the anterior margin formed 

 by the limits of the dusky base, the posterior a black scale line edging the brown 

 median space; the line irregular, with a larger outcurve between veins 1 and 2, and 

 a sharp inward tooth on vein 1. The median space is narrow, brown-powdered, with 

 the round black reniform (which is annulate with yellow) fonning a conspicuous 

 feature, the outer margin formed by an edging of black scales, of which the small 

 lunate orbicular forms part and the irregular inner part of the t.p. line forms the 

 remainder. Beyond this the wing is creamy to the brown terminal space, the s.t. 

 space appearing bluish from the dark band of under side, the edges of which are a 

 little marked by brown scales on the upper surface. S.t. line not defined, the termi- 

 nal space narrow, and irregularly brown-powdered. A series of distinct black ter- 

 minal lunules at the base of the long, brown, pale interlined fringes. Secondaries 

 blackish, with a broad yellowish white median band in which is a large blackish 

 discal lunate mark. Beneath, primaries mottled, blackish and yellow; a distinct, 

 extra-median, broad outer band forming the most conspicuous feature. Second- 

 aries pale yellowish, with a large blackish discal mark and a narrow, broken, 

 irregular sub-terminal blackish band. A broken dark terminal line on all wings.
