Habitat.— Para, Brazil. Two males and two females in coll. B. Preston 
Clark; two males in Mus. Tring; two males in coll. of my friend Rev. 
Arthur Miles Moss, by whom all these specimens were raised, and for whom 
the species is named. 
Male. First segment of palpi light yellow beneath, irrorated with light 
brown, warm reddish brown laterally; second and third segments brown, 
shading to warm reddish brown toward the eyes. Eyes large, fully as much 
so as in X. rufescens, and dark brown in color. 
Head, thorax and abdomen above, brownish clay-color, darker toward 
the head; yellowish brown beneath. Abdomen with a few golden brown 
lateral scales on posterior segments; light yellow side tufts at base; black 
spot on first segment. Antennae light brown above, white beneath. Legs 
very light brown. 
Fore wing above, brownish clay-color like thorax. Unicolorous, save 
for the following markings. A narrow yellow subbasal band on the inner 
margin 7 mm. in length, black apically and basad. Minute black stigma 
on cell. A faint postcellular shade lying between the stigma and the distal 
margin, and extending to a faint median transverse line that runs from a 
median point on the inner margin to a point on the costal margin 11 mm. 
distant from the apex. Parallel to this line distad, and 1 mm. from it, ex- 
tends a line, faint at all points and becoming almost invisible costad. An 
equally faint submarginal line runs parallel to the distal margin, distant 
from it about 5 mm., accentuated by faint black vein dots, and terminating 
at the apex. A few black scales make a spot on costal margin 7 mm. from 
the apex. A few black submarginal scales on the veins, and at the wing 
apex between the veins. 
Hind wing above, black. A light yellow submarginal band, shaded with 
black, reaching nearly to the costal margin, dilated basad on SM2, followed 
by a marginal patch at anal angle reaching to the base of the wing. 
Both wings beneath, brownish clay-color, slightly irrorated with black 
scales, especially on the veins and toward the distal margins. Fore wing 
with a roughly triangular postcellular black shade extending two thirds 
of the way to the hinder angle, and fading out costally. A series of vein
