We have received a few specimens of this species from Central America. From 
Ecuador I have a large series, which do not show any variation. None of the examples 
before me have the margins of the wings so red as shown in Snellen’s figure. Central - 
American specimens are brighter in colour than those from South America.

This species is not uncommon throughout Tropical America, but I have not seen 
a specimen from north of Mexico. It varies greatly in size, also in the shape of the 
yellow hyaline spot on the primaries. 
7. Eudioptis praxialis, sp.n. (Tab. LXI. fig. 28.) 
Primaries dark glossy-purplish-brown, with a large square hyaline yellowish spot below the cell extending to 
the inner margin; secondaries pale hyaline yellow, broadly bordered with purplish-brown, the inner 
margin of the border straight ; the fringe purplish-brown: head, thorax, and abdomen blackish-brown 
above, white beneath ; the antenne blackish-brown, the legs yellowish-white. Expanse 1,8, inch. 
Hab. Costa Rica, Santa Clara Valley 1200 feet (Ziircher); Panama, Chirigui (Trotsch, 
in mus. Staudinger). 
Three specimens. ‘This species is allied to EH. nitidalis (Cram.), but it is a much 
larger insect, and easily distinguishable from it by the distinct border to the secondaries. 
We figure a male from Costa Rica.
