ZEONTA. 389 
Zeonia contains about eight species spreading from Nicaragua to South Brazil; only 
one occurs within our borders and this is also found in Colombia. 
The wings being for the most part hyaline render it a conspicuous genus, which is 
usually associated with Erycina, but from which it differs in several important par- 
ticulars; the neuration of the secondaries as well as their shape suggests a relationship 
with Diorhina, the prolonged palpi of which latter genus readily distinguish it. 
The subcostal nervure of the primaries of Z. corineus emits its three branches beyond 
the cell; the first branch sometimes forms an anchylosis with the costal nervure; the 
middle discocellular is perfect and meets the subcostal at an acute angle; the lower 
discocellular is curved, atrophied in the middle, and meets the median beyond the 
second branch; the costal side of the cell is longer than the median side. ‘The secon- 
daries have a very long basal nervure ; both discocellulars are atrophied, the upper meets 
the subcostal beyond the first branch, the lower joins the median beyond the second 
branch ; the two branches of the median start close together and diverge very gradually 
from the median, the first branch is prolonged and carries a tail-like appendage ; the 
costal side of the cell is much shorter than the median side. The front legs of the male 
have the trochanter inserted before the middle of the coxa; femur >+ coxa; tibia 
<coxa, dilated in the middle; tarsus==femur-+ trochanter, there are two constrictions 
indicating the tarsal joints. The terminal joint of the palpi is very small, <4 middle 
joint, which tapers towards its distal end; basal joint stout =4 middle joint; antenne 
forty-three joints, the terminal seventeen forming a moderate club. 
The harpagones in the male secondary sexual organs are slightly setose; between 
them in the middle line is a long slightly upturned setose spine; a piece apparently 
arches over the penis between the upper lobes of the harpagones. The penis tapers 
very gradually to the end and is slightly decurved ; the strap connecting its base with 
that of the harpagones is directed outwards and then bent back again.

Central-American examples agree best with those from Colombia, which we have 
little doubt are referable to Z. bogota of Saunders. This form is closely allied to 
Z. amazona of the Amazons valley, the chief, if not the only, differences being the 
absence in that species of the blue gloss on the wings beneath, and in the scarlet patch 
being rather larger and more narrowly edged with black between the ends of the sub- 
median nervure and the first median branch.
