This insect is a southern race of NV. lycorias, taking its place in Nicaragua and 
extending its range to Panama. It is common in Costa Rica, and occurs again in 
Calobre in the State of Panama, but we have no specimens from the district of Chiriqui, 
which is somewhat remarkable. In Western Colombia there is a still more modified 
form which we describe below *. 
PANDEMOS. 
Pandemos, Hubner, Verz. bek. Schmett. p. 25 (1816) ; Westwood, Gen. Diurn. Lep. p. 440 (1851). 
We are acquainted with but four species belonging to this genus, three of which are 
known only from single specimens; the fourth is P. arcas, the type of the genus which 
we here describe. Two species occur within our limits. 
The subcostal nervure of the primaries emits two branches before the end of the cell 
and one after it; both the lower and middle discocellulars are atrophied, the upper 
meets the subcostal at the same point as the upper radial, the lower the median beyond 
the second branch ; the costal side of the cell is a little longer than the median ; there 
is a large patch of thickly felted scales below the junction of the median and its first 
branch. ‘The secondaries have a basal nervure, both discocellulars are atrophied, the 
upper meets the subcostal a little beyond the first branch, the lower the median nearly 
opposite the second branch ; the costal side of the cell is a little shorter than the median ; 
there is a patch of thickly felted scales between the costal and subcostal nervures 
corresponding to the similar patch on the primaries. In the female these patches are 
absent. 
The front legs of the male have the trochanter inserted beyond the middle of the 
coxa; femur >4 coxa, ovoid and dilated towards its distal end; tibia < coxa; tarsus 
> ¢ tibia, two-jointed, with a constriction in the terminal joint, the remnant of an 
atrophied third joint. The terminal joint of the palpi in the male are long and 
slender, =% middle joint; that of the female is much longer, =? middle joint. The 
antenne have fifty-four joints, the terminal seventeen forming a slender club. 
The harpagones of the male in the secondary sexual organs are subtriangular, the 
apex being a simple lobe slightly setose; a short rod proceeds from the base of the 
harpagones in the middle line, and the strap passes from the middle of the penis to the 
base of the harpagones. The penis itself gradually tapers, and is decurved throughout 
its length.
