This species is intermediate between G. LatreiUana Kirby and C. 
venom Walker, and very distinct from either. 
In size it approaches the former, and in the shape of the wings and 
markings of the anterior pair, the latter species. 
In {7. venom the stripes on the anterior wings are however yellow, 
and there is a third on the subcosto-inferior nervule which is wanting 
in G. Gressonana. The two terminal joints of the palpi in G. venom 
and G. Latreillana are black, while in the species just described the 
terminal joint alone is black. The white fringe on the posterior 
wings in (Z venom is interrupted with black about two-thirds of the 
width of the wing from the anal angle; in G. Gressonana the fringe 
is entirely white. 
I have dedicated this species to my friend, Mr. E. T. Cresson, of 
Philadelphia. 
EUDRYINA. 
CIKIS, n. gen. 
Antennae bi-pectinate in both sexes (?). Pectinations straight, ex¬ 
tending along the inside of the antennae from the base to the tip. An¬ 
terior wings with the costal margin straight; apex rounded, acumina¬ 
ted; exterior margin less oblique than in Eudryas] internal margin 
straight. Thorax and abdomen stout, latter crested only on first seg¬ 
ment. 
This genus, founded on a Texan species of which a description fol¬ 
lows, shows a great affinity to Eudryas) the most observable differen¬ 
ces are presented by the pectinated antennae and the somewhat broad¬ 
er and stouter wings. In the shape of the anterior wings it resembles 
the genus Ovios^ represented by an African species 0. capensis^ H. S. 
The pterogostic characters, owing to paucity of material, I have not 
been able to examine. 
C. Wilsonii, u. sp. (See plate 3, fig. 1.) 
Anterior and posterior wings white. Antennae doubly pectinated 
to the tips; stem white, powdered with black at base. Palpi black, 
powdered with white atoms. Head black; tegulae white. Thorax
