defined marginal band and a paler ground-colour, as well as a narrower dark margin; common in French Guiana. 

 heUoils. — heliotis Bat. differs considerabh' by the ground-colour being a pale ochreous-yellow with a brownish tinge. — 

 leucidiodes. leucidiodcs /orm. nov. (142i) is a pj-gmean form of which a series is before me from different places of Guiana 

 ascolia. and which may be the inhabitant of particularly dry habitats. — ascolia Hew. (142 k) is a large form, closely 

 allied especially to cachrus and menalcus, recognizable by the very broad margins and a small red band in the 

 (iscoUdes. anal part of the hindwings. — ascolides Bsd. exhibits an entirely black abdomen which in cachrus is whitish 

 at the sides and beneath, partly also above; otherwise not differing from ascolia worth mentioning; from Central 

 augea. America. — augea Drc. (142 k) differs from ascolia only by a greater extent of the red band of the hindwing 

 reaching in the ^J almost to the apex, in the $ even beyond it to the forewing. Most of these forms are con- 

 nected with each other bj' transitions and may scarcely be assumed to be subspecies. Common. 

 eidrapela.. N. cutrapela Bat. may also be only a form of the preceding species. Forewing with a dark-brown costal 



streak, a dark-brown base and a broad brown marginal band. From the costal stripe small transverse stripes 

 extend into the white of the wing, which projects with 2 continuations into the brown marginal band; in the 

 latter we notice the white arcuate streaks, being also distinct in menalcus, in front of the marginal band at the 

 anal angle sometimes a little red-yellow. Recognizable hy the abdomen being all white on both surfaces. Lower 

 Amazon. 

 ninias. N. ilinias Hetv. (140 d, as minias). White, without the dark costal stripe, the apical part of the 



forewing broadly violettish-brown, with white markings and anteriorly shaded with an ochreous yellow; hind- 

 medusa. wing with a similar marginal band. Upper Amazon. — medusa Drc. (140 d) which we figure from Humayta, 

 but which flies quite similarly also in Peru, exhibits the marginal band of the hindv/ing reduced to few small 

 (jahtriuia. dark marginal spots; — and in galactina Stick, there is no marginal marking whatever on the hindwings; from 

 Cuyaba in Matto Grosso and on the Amazon. — Beside such specimens with purely white hindwings, however, 

 there are near Cuyaba also such with a complete black, pioximally undulately defined marginal band of both 

 wings; they also have the dark basal spot along the costa of the forewing further expanded and they would 

 undimargo. then also have to be denominated: undimargo form. nov. (142 i). • — Not rare. 



leucosia. N. leucosia Hbn. (140 d). Pale yellow, at the apex and above the anal angle of the forewing as well 



as at 3 places of the margin of the hindwing violettish-brown, white-marked spots. The ba^e of the wings is 

 likewise brown. Lower Amazon: Obidos, Santarem, Para. Rarer. 

 kadenii. N. kadenii Fldr. (140 d). This species unknown to me in nature resembles an acherois in which the 



white is increased, the dark marginal band reduced and the orange stunted to a small subcostal spot. In front 

 of the border, the marginal band is traversed by a metallic line. Venezuela. — Stichel thinks it probable 

 that the species belongs to the following genus. 

 cyneas. N. cyncas Heiv. (139 e). Yellow with a black, unmarked margin. A mimetic copy of a homochromous 



Cyllopodina together with which the animal flies in Peru and Bolivia. The figured specimen originates from 

 the Chanchamayo and has a broader margin than Bolivians. Beneath exactly like above. — The Nymphidium 

 are not mimetic and it is, therefore, not likely that this species belongs here. The compact structure and the 

 exterior borrowed from other butterflies much rather assign the species into the following genus, and the latter 

 is again probably rather closely allied to Esthemopsis, Ithomiola or another of the mimetic genera than to the 

 Nymphidium, bemg similar merely in the exterior. 



89. Genus: Ijnelcla Heu\ 



Only 2 or 3 distinct species are reckoned hereto, but presumably- also the last species enumerated among 

 the N ymphidi'um belongs to this genus, since it certainly does not represent a genuine Nymphidium. Kibby 

 inserts the genus between N ymphidium and Lucilla, Mexgel adds it to Zelotaea, Stichel places it between the 

 (newly established) genus Ulajjhrotis {telephus Cr.) and Astraeodes. 1 he species have an imcommonly small 

 head with a narrow forehead, a globular thorax and an abdomen that does not reach the anal angle of the hind- 

 wings. The wings, of a normal shape, exhibit the cell of the hindwing comparatively very long for an Erycinidae; 

 the upper median vein of the forewing branches off far before the lower cell-angle. 

 mycea. I. Hiycea He^c. (= glaucosmia $ Thth.). ^ whitish-yellow, $ mostly paler; in the black margin at the 



acnctus. apex 3 small white spots and in front of the border a yellow, lustrous line. Colombia. — aenetus Heiv. (= oenetus 

 Mengel) (128 i) has the small apical spots smaller and the metallic line in the marginal band of the hindwing 

 leucophry- bluish-grey; Bolivia and Peru. — As leucophryne Stich. (128 i) I figure a specimen from Marcapata (Peru, 

 "*"• 4500 ft), beside a Bolivian specimen, in order to show on what slight differences this form is based. — Not 

 very rare. 

 glaucosmia. I. glaucosiTiia Heiv. (12$ i). Dark blue, of a metallic lustre, parallel to the border 2 or 3 black lines; 



recognizable by the small white subapical band of the foiewing. Ecuador. — In a specimen before me from 

 Colombia (Pacho, 2200 m, captured by F.assl) the proximal lines are streighter, the small white band traversed 

 by strong veins, and in front of the small band there is yet a tiny costal spot. I consider this to be only a 

 ierpna. local aberration; Stichel denominates such Colombian specimens terpna. — glaucosmia shows a homochromism 

 with Mesosemia, the preceding species with certain Terias.
