veins. Fore wing with a black S-shaped line from the inner margin to the 
costal margin, duplicating the inner transverse line of the upper side, but 
curving easily, and not sharply angled at SC5. A series of vein dots 
parallel to the outer margin, and distant from it 7 mm., takes the place of 
the outer transverse line of the upper side. Black dot on costal margin 
9 mm. from apex, as on upper side, but smaller. 
Hind wing with a faint median line parallel to the outer margin, and 
sharply angled at SC2, reaching the inner margin midway of its length. 
A series of arrow-shaped vein dots runs parallel to this line midway between 
it and the outer margin. 
The inner margin of the fore wing nearly to the outer angle, a basal spot 
on the fore wing, a fold at the anal angle of the hind wing, the legs, and the 
side tufts of the abdomen are yellow. These latter make a nearly con- 
tinuous line on each side of the abdomen laterally. 
This is a remarkable form, being in its coloration and the trans- 
verse lines of the fore wing allied to the adalia group, and in the 
location of three black spots on the fore wing being affiliated with 
that to which X. ockendeni belongs.

Habitat.— Costa Rica. Two males in coll. B. Preston Clark, received 
from Mr. A. H. Fassl, Teplitz, Bohemia. 
Shape of wings and type of coloration like X. thyelia, but pattern entirely 
different. Head, thorax and abdomen above and below of same color as 
in thyelia, except that median dorsal line in the latter is heavier and pink. 
Fore wing, above: Chocolate-brown basal area sharply defined out- 
wardly, extending from the costal margin, at a point about one third the 
distance toward the apex, across the wing to the inner margin. This area 
lighter brown in the folds. Lines 1 to 5 are chocolate-brown. Line 1, 
beginning at SC5, runs in an irregular curve to the inner margin, almost 
meeting there the hinder angle of the dark basal area. Costally of line 1 
is a light brown area extending from the dark basal portion of the wing to 
the apex, with a darker brown median cloud, and irrorated with dark brown
