Mr. Bates described this species from examples in our collection from Panama, whence 
we trace it northwards to Guatemala. Two female specimens from the latter country 
have indications of a submarginal row of black spots on the secondaries, but this alone 
will hardly justify their separation. 
The type of Mr. Butler’s Emesis irata, a female, is in our collection, and can be 
exactly matched in our Panama series. 
There is a slight amount of variation in the amount of black at the base of the 
primaries. Some specimens have a spot isolated from the rest of the black border, in 
others it is joined to it, in others, again, it is wanting altogether. 
S. menetas (Drury) is an allied species from Brazil which may be distinguished by 
the black border to the secondaries, a character which also separates other forms found 
in the valley of the Amazons. 
Found in the dense forest region of “ the tierra caliente” (Champion).

Seven or eight species of this genus are known to us, chiefly belonging to the 
Amazons region, but found also in the neighbourhood of Bahia in Eastern Brazil, and 
as far north as Nicaragua within our country. It is closely allied to Mesene, but we 
find differences in the male organs which probably warrant its separation. 
The subcostal nervure of the primaries emits two branches before the end of the cell 
and one after it; the upper radial and the atrophied middle discocellular leave the subcostal 
at the same point ; the lower discocellular is also atrophied and meets the median a little 
beyond the second branch ; the costal and median sides of the cell are nearly equal. The 
secondaries have a basal nervure; the upper discocellular leaves the subcostal a little 
beyond the first branch, the lower meets the median beyond the second branch; the 
costal and median sides of the cell are nearly equal. 
The front legs of the male are slender, the coxa extends far beyond the trochanter 
joint, femur > 2 coxa, tibia = coxa, tarsus > tibia and has two joints and two sete 
at the end. The front legs of the female have the second and last joints about equal, 
and greater than the third and fourth, the last has a setose pad on the under 
surface, the rest have two strong spines at the extremity of the under surface. The
