EXOPLISIA, gen. nov. 
On examining the species described by Dr. Felder as Amarynthis hypochalybe, we 
found sufficient important points to necessitate its removal into a separate genus. The 
second costal branch of the primaries is emitted much nearer the end of the cell than 
in Amarynthis, and there are differences in the secondary sexual organs of the male, which 
will be described in detail below. 
Exoplisia, as we propose to call the genus, is a Colombian insect, stated by Boisduval 
to occur in Nicaragua. 
The subcostal nervure of the primaries emits two branches before the end of the 
cell, the second being almost opposite the middle discocellular; the third branch is 
emitted a long way beyond the cell, as is also the upper radial ; the lower discocellular 
meets the median a little beyond the second branch; the costal side of the cell is a 
little longer than the median side. The secondaries have a strong basal nervure; the 
atrophied discocellulars run nearly in a line across the wing, the upper meets the 
subcostal a little beyond the first branch, the lower the median beyond the second 
branch; the costal side of the cell is much shorter than the median side. 
The front leg of the male has the trochanter inserted before the middle of the coxa; 
femur=4 coxa, and is considerably dilated towards its distal end; the tibia is also 
dilated =? coxa; tarsus=tibia, a constriction near its extremity indicates the remains 
of a joint; there are two or three spines close to the end, and two or three others 
distributed sporadically. The eyes are hairy. 
The male secondary sexual organs are very similar to those of Zasaia and Caria. The 
harpagones are single lobes, setose and rounded at the extremity; they are united by a 
piece which passes over the penis, and is slightly convex outwards, with a short point 
in the middle line, where it is covered with long sete; dependent from this on either 
side of the penis is a stout slightly upturned hook, blunt at the end and setose along its 
upper edge ; outside these, again, are two short subtriangular setose lobes. The penis 
is sickle-shaped ; from the angle the strap proceeds outwards, makes a fold near its 
extremity, and then turns abruptly backwards to the base of the harpagones ; close to 
the bend on the upper side is a cluster of spines, curved outwardly, just as in Lasaia 
and Caria. In the former genus Ezoplisia might well be placed, were it not that the 
palpi do not project as is the case in Lasaia.
