Annals and Magazine of Natural History (7) 3: 228-236; pp. 232-233 (as Esthema eulalia). Primaries black, the apex edged with white; a curved white hyaline band, crossed by the black veins, beyond the middle of the wing, but not reaching either margin; the fringe black, excepting at the apex: secondaries black, shaded with dark blue along the inner margin from the base to the anal angle; a band of white streaks partly crosses the wing beyond the middle nearest the apex; the fringe white. The head, antennae, and thorax black; the abdomen bluish black above, the underside grey; legs greyish black. Expanse 2 1/2 inches. Hab. Upper Amazons (Mus. Druce). This species is allied to Esthema confluens, Felder. Hering, M. (1925). Pericopidae. In: Seitz, A. (ed.), The Macrolepidoptera of the World, vol. 6, The American Bombyces and Sphinges. Alfred Kernen, Stuttgart; p. 436, pl. 61 d (as Eucyane eulalia). E. eulalia Drc. (61 d) is likewise similar to speciosa, ventrum blue with quite narrow white segmental margins. The discal bands are less broadly crossed by black, those of the hindwing are farther distally removed. The speciosa paragraph referred to (same work, p. 435, pl. 61 d): E. speciosa Wkr. (= herrona Btlr.) (61 d). Blackish-blue, with white discal bands, which are broadly crossed with black by the veins. Fringes at the apex and partly at the tornus white. Ventrum blue with white segmental margins. In the form venosa Fldr. the discal band of the hindwing is expanded to the base, so that the hindwing appears white with a blackish-blue margin. Colombia and Upper Amazon River.
