Is wliite ftiul the outer bonlei- of both wiiijrs (llstiiictly, but narrowly, the apical portion 

 of the costal inarj;in of fore winjrs very narrowly, and the costal border of the hind 

 wings as far as the costal ncrvuie. niar;;ined with l)lackish Itrown; inner margin of 

 hind wings fuscous, heavily tlecked with pale lilne; fringe very pale bluisli wliite, 

 infuscated at the extreme base. 



Ueneath pale lioary slate gray. Fmy trhiiis with the apex of tlie cell niarlied l)y a 

 pretty large transverse lilaci; bar, attenuated below, encircled witli white; midway 

 between this and the outer border is a somewhat sinuous or l)ent series of six mod- 

 erately large, subecpial, black spots encircled with white, suljparallel to the outer 

 border; the upper one is round, the next three roundish or rounded triangular, the 

 rtfth generally the same, but sometimes extended diagonally to the lower mediau in- 

 terspace toward the base of the wing; the lowermost sometimes roundish but usually 

 a little linear, having the direction of the bar at apex of the cell; the second spot is 

 usually a little nearer the outer border than the first or third, but sometimes is on a 

 line with tliem and the series is then bent at the third spot ; a little nearer the outer 

 border tliaii this extra-mesial row of spots is a series of ratlier indistinct, dark brown 

 liuiules, opening outwards par.allel to the outer border, surmounted faintly by wliitisli 

 and surmounting very pale orange spots, sometimes almost entirely pale, bordered 

 exteriorly, narrowly and faintly with dusky; the outer margin is narrowly edged with 

 blackish, sometimes enlarging into minute spots at the nervure tips. Fringe as above. 

 Iliml iriiiys with a transverse curved .series of small, roundish, black spots encircled 

 with white in the middle of the base of the wings, in the costo-siibcostal interspace, 

 in the middle of the lower half of the cell, in the medio-submedian and tlio submedio- 

 internal interspaces ; the tip of the cell is marked as in the fore wings but more nar- 

 rowly ; beyond is a transverse series of eiglit rouudisli l)lack spots, encircled narrowly 

 with whitish, arranged in a double curving row; above tlie lower median interspace a 

 very strongly curving row aud below one rather less so, each with its convexity out- 

 ward ; the spots in the costo-subcostal, the lower median and the raedio-submediau inter, 

 spaces are in nearly or quite the same line as the bar at the tip of the cell ; the first 

 to third spots are in a very slightly curved row and the third to sixth are in a 

 similar row at nearly right angles ; that in the lower subcostal interspace is at about 

 two-fifths of the distance from tlie tip of the cell to the outer l)order; there is a sub- 

 marginal row of roundish dark brown spots, the inner half of whicli is. in most of 

 them and particularly in the median interspaces, covered by very pale metallic green 

 ish scales ; they are surmounted by rather pale orange lunnles, edged inwardly with 

 blackish spots, generally assuming the form of rather narrow bent lunules. Outer 

 border narrowly edged with blackish brown, sometimes broadening slightly at the 

 nervure tips. Fringe as in the fore wings. 



Abdomen dark brown above, with scattered pale blue or wliitish scales and hairs, 

 the former growing more abundant down the sides; beneath wliitish. .Vppendages of 

 male (34: 2'.)) with the alatious forming posteriorly extended, tapering, pointed 

 fingers, slightly swollen at the base, running parallel toeachotlicrand leaving between 

 them a narrow and exceedingly deep cleft; lateral arms normal, very slight and 

 elongated. Clasps formed on each side of a broad, snbequal, scarcely swollen lamina, 

 somewhat more than twice as long as broad, the apical m.argin angulate and sliglitly 

 produced, the produced part apparently split and slightly incurved. 



Accessory sexual peculiarities. As described above, the sexes difl'er in coloring 

 on the upper surface of the wings. The same surface bears scattered androconia in 

 the male (46 : 29) , which are of very regularly obovate form, but with the middle of the
