HETARA, 65 
Of this singular species we only possess female specimens; so that we are unable to 
examine all the points which would fully justify its being placed in this genus rather 
than in Hetwra, where it has usually stood. The neuration of the secondaries, how- 
ever, is that of Callitera; and the presence of one and not two ocelli on the same 
wings points in the same direction; so that we have little hesitation in placing the 
species in this genus. Its peculiar rounded wings, and the absence of any of the bright 
colours of Callitera, make it very distinct from any of its congeners. 
The species is a rare one, and was originally one of Belt’s discoveries in Nicaragua, 
whence we have specimens. As it is also found in the neighbourhood of Chiriqui, it 
may be looked for in Costa Rica, from which country, however, no specimens have yet 
reached us.

Restricting the use of this name to H. piera and its immediate allies, the genus 
contains four or five species which are distributed over nearly the whole of Tropical 
South America from Costa Rica to South Brazil, one species (H. macleannania) coming 
within our limits. Some of the diagnostic characters of the genus, as distinguished 
from Cailitera and Pierelia, consist in the male having the tibia of the front legs 
slender and the tarsus only about half the length of the tibia. In both sexes the 
lower discocellular of the secondaries meets the median close to the common origin 
of the second and third median branches, and the proximal segment of the subcostal 
is about equal to the proximal segment of the median. The wings are diaphanous as 
in Callitera. 
In one respect Hetwra differs widely from both Callitera and Pierella; and that is, 
in the secondary sexual characters of the male. In the former the upper hook (the 
‘“‘teoumen ” of Buchanan-White), besides the central spine (which itself appears split), 
has two short lateral projections as in many other Satyride. The lateral jaws (the 
‘“harpagones”) have a prominent tooth on the upper edge. In both Callitera and 
Pierella the tegumen has a simple central projection, and the harpagones have a 
smooth upper edge without any tooth, as in Hetera.
