Diaphania praxialis (Druce, 1895) Druce, H. (1895). Biologia Centrali-Americana. Insecta. Lepidoptera- Heterocera, vol. 2: p. 231, pl. 61 fig. 28. 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 antennae blackish-brown, the legs yellowish-white. Expanse 1 7/8 inch. Hab. Costa Rica, Santa Clara Valley 1200 feet (Zurcher); Panama, Chiriqui (Trotsch, in mus. Staudinger). Three specimens. This species is allied to E. 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.
