Head and thorax white or creamy. Abdomen a little gray, with narrow white 

 ring;s faintly indicated in the female. Primaries white at base, above the median 

 vein extending to the s. t. line; below the vein extending to the middle of the 

 median space in the male to the t. a. line only in the female. Basal line indicated 

 on costa. T. a. line marked on the costa, and in the female defined below the 

 median vein by the gray portion of the wing, in the male the line is more or less 

 indicated by gray shadings. Basal space otherwise also gray clouded in some 

 examples. Outer part of wing luteous brown in the median space, more or less 

 violaceous in the s. t. space ; luteous brown in the terminal space. Median .shade 

 marked on the costa and again below median vein, where in the male it forms 

 the inner border of the dark part of the wing. T. p. line dusky on the costa, 

 then whitish, narrow, irregular, often in great part obsolete. S. t. line whitish, 

 irregularly sinuated and toothed, preceded by brown shadings below the apex 

 and again at about the middle. Terminal space brown. A series of small black 

 terminal lunules. Fringes brown, cut with white at the middle. Orbicular a 

 black dot, always distinct in the female, tending to disappear in the male. Eeni- 

 form small, I'ouiid, a black or brown ring, white or yellow center. Secondaries 

 white in the male, with a narrow smoky outer border. Yellowish in the female, 

 with a much broader smoky outer shading. Beneath, primaries blackish, with 

 a yellowish streak in the cell, and a subapical mark on costa. Secondaries whit- 

 ish, with a narrow smoky outer border and a smoky spot on costa toward apex. 



Expands 17-20 mm. = .68-.80 inches.

Four males and eight females, the difference in maculation con- 

 stant between the sexes. In all the females the dark shade begins 

 at the t. a. line below the cell ; in none of the males does it begin 

 before the median shade. In the niales the orbicular becomes much 

 reduced, and in two examples is entirely wanting. 



As for the rest, the variation is chiefly in the amount of gray 

 shading in the basal space and along the costa. There is also a 

 difl^erence in the s. t. and terminal spaces, which tends to become 

 mottled. 



The primaries are a little narrower than usual, tending to sub- 

 parallel. Secondaries with 5 weak, well removed from the median, 

 out of the cross vein, a real trifid ; 8 and 4 branch well beyond the 

 end of the cell. 



Acontia libedis n. sp. 



Head and thorax creamy white; abdomen white or faintly yellow tinged. 

 Primaries yellowish or creamy, the terminal space mostly gray, a large quadrate 

 gray and brown patch a little beyond the middle on the inner margin. This 

 patch extends from the median shade to the t. p. line, and from the inner mar-
