The female which we attribute to this species is very like 7. ivtus in general appear- 
ance, so much so that we long thought it belonged to that insect ; but, in spite of its 
more silvery underside, we now think it really belongs here. The middle of the 
caudal appendage of the secondaries is fulvous, as in the male, and it has other slight 
characters which point to 7. alcibiades rather than to 7. livius. This female was in 
one of Arcé’s collections sent from the province of Veraguas.

A very pretty species, confined, so far as we know, to Costa Rica, Panama, and 
Colombia. It is of a pale brown crossed by dusky lines, the outer half of the primaries 
and raargins of the secondaries being marked with white spots. Beneath the wings 
are of a pure silvery white, crossed with pale ferruginous lines as in 7. livius. 
It is a close ally of 7. egina, which, however, besides being smaller, has fewer spots 
and has a more southern range. 
Timetes merops is the type of the genus Timetes, being well figured under this name 
by Blanchard in the illustrated edition of ‘ Cuvier’s Régne Animal.’ |
