region are darker, it is remarkably constant in its characters. In Guatemala it is found 
in the lowlying portions of the country and up to an elevation of about 3000 feet. 
Mr. Bates met with it in the same situations as Callizona acesta, settling on the trunks 
of trees in the same way ; but though it has considerable resemblance on the underside 
to that insect, not only does it differ in the shape of the wings, but also in many other 
important points of structure, as we have indicated above. 
ECTIMA. 
Ectima, Doubleday, Gen. Diurn. Lep. p. 227 (1849). 
This genus contains four or five species, some of which are not very clearly defined. 
These range over the whole of Tropical America from Southern Brazil to Nicaragua, 
no species, however, being found as yet in the West-Indian islands. 
The species all bear a strong resemblance to one another, being mottled above, 
somewhat as in Ageronia, and with a distinct bar across the primaries. Like the 
Ageronie the species of Ectima settle on tree-trunks and lie with the wings expanded. 
The subcostal nervure in Ectima emits the first branch before the end of the cell, the 
second some way beyond it; the upper discocellular is very short, the middle much 
curved, and the lower an atrophied nervule reaching the median just beyond the origin 
of the second branch. The front legs of the male have a stout coxa >} femur- tro- 
chanter; the femur, tibia, and tarsus are all slender, the tibia slightly> tibia, tarsus 
4 tibia; the tarsus has two joints. Eyes smooth. Palpi slightly hairy; terminal 
joint=# middle joint, which is slender and of uniform width throughout. Antenne 
with 34 joints, of which twelve form a rather abrupt club. ‘The male secondary sexual 
organs have a tegumen with a slightly depressed hook, below which is a projection 
pointing outwards in the middle of the anal cavity; the harpagones are simple narrow 
lobes, hairy at their extremity and along the ventral edge. On the ventral surface and 
independent of the harpagones and tegumen is a long chitinous rod forked at its distal 
end and reaching almost to the end of the harpagones. ‘This rod is not an extension of 
the penultimate segment, but extends as a rod into the abdomen, reaching beyond the 
withdrawn penis. The latter is straight and not curved as in Gynweia.
