terminating in a point. Vinculum weak, not coalesced. Tegumen 
broad; truncate posteriorly. Anellus an elongate, lightly sclerotized, 
curved plate. Aedeagus stout, abruptly curved at distal third, sharply 
pointed; vesica armed with a single cornutus about half the length of 
aedeagus. 
Holotype: U.S. National Museum No. 69747. 
Type-locality: Guatemala, Palin. 
Distribution: Known only from the type-locality. 
Described from the unique male holotype. (July. Schaus and 
Barnes). 
On the basis of the male genitalia I am placing this species in 
Carolella, but on habitus it is far removed from the North American 
members of the genus. In asthenia the apex of the median projection 
of the transtilla is spinous but in the type of the genus, Pharmacis 
sartana Hubner, it is smooth. The aedeagus of asthenia is less stocky 
than that of sartana and the cornutus is more slender.

Labial palpus white; second segment light ochraceous buff, irrorate 
with fuscous on outer side. Antenna light grayish fuscous, whitish 
dorsobasally; scape creamy white. Head creamy white; posteriorly 
and laterally ocherous white. Thorax ocherous white with light in- 
fuscation anteriorly. Forewing ground color creamy white; basal 
patch small, primarily indicated by a small grayish-fuscous spot 
on costa at basal fifth, continued transversely to fold, then inwardly 
to dorsum as a pale, ill-defined buff line; on middle of costa a large 
erayish-fuscous blotch continued to middle of cell; at apical third, 
on costa, a grayish-fuscous spot continued transversely and out- 
wardly to vein 5 as a grayish-buff fascia; at end of cell a small fuscous 
spot followed outwardly by an ill-defined, irregular, transverse, pale 
buff fascia; from vein 5 around termen and tornus and along dorsum, 
a series of short, fine, fuscous strigulae; underside strongly infuscated 
except along costa; cilia mixed buff and white. Hindwing sordid 
white shading to and mottled with grayish fuscous at apex and outer 
margins; cilia sordid white with gray subbasal band. Foreleg creamy 
white; femur and tibia irrorate with fuscous on outer side; tarsus
