PYRRHOGYRA. 
Pyrrhogyra, Hibner, Verz. bek. Schm. p. 48 (1816); Westw. Gen. Diurn. Lep. p. 252. 
A Neotropical genus, containing about eight species, which are spread from Mexico 
to Brazil to the exclusion of the West-Indian Islands. 
Within our region five species occur, of which all but P. hypsenor are also found in 
some part of the South-American continent. 
Besides the coloration of the species, which is somewhat peculiar, the members of 
Pyrrhogyra can readily be distinguished by the great difference between the terminal 
joint of the palpi in the male and female, being short in the former and very long 
in the latter. 
In P. edocla the subcostal nervure of the primaries emits two branches before the 
end of the cell, these branches lying close to one another as they approach the costa; 
there is no upper discocellular ; the middle is nearly straight and in a line with the 
lower radial; an atrophied lower discocellular meets the median nervure a little beyond 
the origin of the second branch. The front leg of the male has a moderately stout 
coxa, >2 femur + trochanter; tibia = femur; tarsus (single-jointed) <tibia. Hyes 
smooth; palpi in the male with a short terminal joint <3, but >$ the middle joint. 
In the female the terminal joint is nearly as long as the middle joint, which in both 
sexes is slender and of nearly uniform width throughout. Antenne with thirty-seven 
joints, but slightly thickened towards the end into a club. 
The secondary male sexual organs in P. edocla have a simple pointed tegumen, from 
which is attached a piece on either side bearing a strong point which projects outward 
in the anal cavity ; these pieces pass onwards to the ventral margin; the harpagones are 
very slender lobes, hairy on the outer surface and at the end; the penis is straight. 
In P. otolais these parts are almost exactly similar. 
All the species of Pyrrhogyra are found in sunny places in the forest, where they sit 
upon the foliage. In the dry season they frequent streams, alighting on rocks and 
stony ground.
