ish scaloa running outwardly to where the outer component line would bo if it 

 were present. Subtenninal line faint, merely indicated by the paler terminal 

 space, preceded by a darker shading which forms a determinate blackish costal 

 shade before the line. A pale line at base of the dusky fringes. Hind wings 

 dusky, a little paler and semi-hyaline at base, nearly like the primaries in tint, 

 with no determinate border or discal mark save by reflection from the under- 

 Burface. Fringes with a pale basal lino. Beneath paler, more whitish ; luni- 

 form discal mark on hind wings distinct, black, fainter on fore wings. A com- 

 mon exterior darker shade line with faint traces of a subterminal shade. Head 

 and thorax dusky ashen ; abdomen concolorous with hind wing. Feet and 

 tibiae blackish, pale dotted.

i $ . — Resembles the foregoing so that a comparative description will best 

 distinguish it. Larger than suhgothicn, of a purplish black color, and hence 

 much darker than suhgothica, with which it coincides in the ornamentation of 

 the primaries above. The t. a. line below the median nervure is more outwardly 

 rounded, less perpendicular ; the prominent claviform is shorter. The ordinary 

 spots are similar in the two species, but the reniform is discolorous in 

 suhgothica, stained with ochreous, with a distinct internal ring, whereas the 

 internal ring is feebly marked and the spot is simply pale carneous, like the 

 orbicular and the pale nervular squamation, in herilis. The t. p. line is more 

 distinct and black in the new species. Hind wings smoky blackish, deepening 

 in color terminally, not pale with a hind border as in suhgothica. On the fore 

 wings above there is a notable contrast between the paler subterminal space 

 and the extended paler marginings to veins 3 and 4 in suhgothica, and the 

 obscurely carneous coloration of the same parts in the new species, which latter 

 wants the decided prolongation of pale scales along the inferior veins. 



Expanse, 38 to 43 m. m. Habitat, Atlantic District ; of common 

 occurrence. T have taken this species in Central Alahanui.
