“Male. Primaries grayish fuscous, with the veins marked with blackish- 
brown scales. The inner half of the wing is somewhat paler, with several 
dirty, white, irregular patches. On the apical third is a narrow, curved, blackish 
transverse band, which forms an angle before it reaches the inner margin. 
Before the outer margin is an irregular, grayish, patch-like band. Hind wing 
grayish fuscous, with an obsolete discal spot of a deeper color. Before the outer 
margin is a distinct broad band of a lighter color, running from a little below 
the apex, nearly to the anal angle. 
Underside, dirty, grayish white, with a broad transverse smoky-gray band 
across the wings. Also a discal spot of the same color. Thorax and body, 
grayish fuscous. Expanse 25 mm. 
Female. Differs from the male by having the transverse band on the 
primaries almost obliterated. Band before the cilia on the secondaries in- 
distinct. Otherwise same as male. Expanse 33 mm. 
One male and one female. Hab. Red River region, Arkansas. Types Coll. 
Chas. Palm.” 
This species is entirely unknown to us. As far as we can judge 
from the photographs received from Mr. C. Palm it would seem best 
associated with the basiflava group.

Until we bred this species in 1911 from larvae so closely approach- 
ing Abbot’s figure in color as to leave no doubt of their identity, this 
species had remained unrecognized or wrongly identified. As the name 
is based solely on a figure we append the following description drawn 
up from 1 ¢ and 2 2 @ in Coll. Barnes. They are the only specimens 
known to us. 
8 Head and thorax gray, patagia and thoracic tuft darker, latter tipped 
with orange. Primaries, ground color rather even purplish gray; a black basal
