mesial band, which as usual includes the vitreous spots; a submari;inal series of 

 ill-deflned, round, blackish spots a little further removed from the border below than 

 above ; occasionally a few scattered, white, elongate scales are found along the nervures 

 and in the grayer parts of the wins, especially on the lower and outer half; outer mar- 

 gin edged with blackisli; fringe dark fuscous brown, nearly uniform. Hind wings 

 very nearly uniform in tint, scarcely so dark as the fore wings, with perhaps more of 

 a chocolate color and furnislied on lower half with long delicate hairs of the color of 

 the ground; a faint, marginal row of small, scarcely paler spots; a more distinct 

 sinuous series of similar, slightly larger spots beyond tlic middle of the outer half of 

 the wing, approacliing the border in the upper median interspace and receding from it 

 in the two interspaces above; outer margin edged with blackish; fringe slightly paler 

 in the hind wings, the extreme tip, especially toward the upper outer angle, whitish. 



Beneath very dark fuliginous brown, with a faint purplish tinge. Fore wings with 

 the whole inner border pale ochraceous. The vitreous spots of the upper surface 

 almost exactly repeated; a marginal row of minute, pale ochraceous, ill-deflned spots, 

 increasing in size below the middle of the wing, and a suljmarginal row of similar, 

 scarcely larger ones, receding slightly from tlie outer border, and above situated mid- 

 way between the vitreous spots and the outer border; these spots are more distinct in 

 the $ than in the ^ , and tlie outer row is sometimes reduced above to longitudinal 

 lines ; the apes of the wing beyond tlie vitreous spots has usually a few scattered 

 hoary scales, especially along the nervules, and sometimes forming the upper of the 

 pale spots ; outer border edged with blackish. Fringe of the ground color of the 

 wing, slightly paler at extreme tip and overlaid at extreme base with whitish or pale 

 ochraceous scales. Bind icings with a double row of faint, pale ocliraceous spots, 

 often obsolescent, especially in the (J , the outer the smaller and marginal, often 

 reduced to longitudinal lines in the middle of the interspaces, the inner sinuous, reced- 

 ing a little from the outer border in the interspaces beyond the cell, but in general 

 parallel to the outer border, extending from the upper subcostal to the submedian 

 nervules in the middle of the outer half or two-fifths of the wing; the anal angle is 

 clouded faintly with ochraceous ; border and fringe as on fore wings. 



Abdomen very dark brown above, becoming gradually lighter on the sides, and dark 

 oehraceous brown beneath. Upper organ of male appendages (36 : 17-20, 28, 29) having 

 the centrum small, not very slender, short, not high. Crest protruding upward and some- 

 what backward into a plump, bulbous ridge, armed with minute points. Hooks very 

 short, very stout, curved, bluntly pointed, widely separate at base, divaricate almost 

 at right angles; from the middle of the ridge, uuiting their bases, depends a short, 

 rather small ilenticle, bluntly conical on a side view, very broadly obcordate on a hind 

 view. Base of the lateral arms greatly produced in a posterior direction ; otherwise 

 directed downward, then bent at more than a right angle backward, the lower edge 

 very soon expanding quite broadly, so as to meet the similar portion of the opposite 

 one beneath, and bearing upon this united belt the inferior armature which occupies, 

 with its minute raised points, a very large and broad field, reaching nearly to the base 

 of the terminal hooks. Left clasp: Main body pretty broad, base obliquely and very 

 Largely docked above, upper margin deeply, broadly and roundly excised just before the 

 lobe; transversely it is a little gibbous, and longitudinally a very little curved. Blade 

 very long, compressed, its upper edge a little incurved, giving it a solid appearance, 

 gradually tivisted so as to bring the outer surface uppermost ; it diminishes in size very 

 gradually to the tip, curving very slightly inward in continuation of the curve of the 

 main body ; viewed laterally It is slightly sinuous in its course, the apex bent inwards 

 nearly at a right angle, rapidly tajiering, terminating in a somewhat blunted point, 

 armed with minute serrulations ; bas.al process directed upward and somewhat back- 

 ward, bent also a little inward, especially by a twist of the hinder edge; it is small, 

 somewhat longer than broad, broader at tip than at base, its hinder edge straight and 

 smooth, its front and upper edge rounded and conspicuously armed with minute teeth, 

 which are borne also, to some degree, upon the outer surface near the tip ; at the base 

 it is very closely connected with the lobe. Lobe forming a very broad and very short
