being the shortest. Antenne gradually taper towards the extremity, having an abrupt 
club. The palpi have a very small terminal joint, the middle one tolerably stout, 
tapering towards the extremity and about four times as long as the terminal joint. 
The secondary sexual organs of the male have the tegumen with two lobes, setose on 
their outer surface towards the ends; between them is a short depressed hook, and in 
the middle what appears to be a central keel, on either side also a strong incurved 
hook. The harpagones bilobed, the lower lobe incurved, and both setose outside 
towards the distal end. The penis is short and truncate, with a broad strap dilated in 
the middle between it and the base of the harpagones; inside are two rows of dentate 
papille which in our preparation reach to a little beyond the orifice; there is also a 
strong chitinous piece, apparently dependent from the penis, upturned with an out- 
wardly serrate edge; the precise attachments of this piece are not clear in our pre- 
paration.

Colombian specimens upon which the name was founded have the white band of the 
primaries rather broader than Central-American examples ; but there seems to be no 
essential difference. 
#. clonia has a much wider range than E. strigosa, being not uncommon in Nica- 
ragua and extending into Colombia, F. strigosa being, so far as we know, confined to 
the district of Chiriqui, where it is much more common than its more widely diffused 
ally. 
It was found by Mr. Champion in the forest region of the low country west of 
Bugaba. It greatly resembles a day-flying moth frequenting the same locality.
