■658 RIODINA; LYMNAS. By Dr. A. Seitz. 



ameiMiw. wing ist entirely blind, i. e. simply indicated by a lighter ground-colour *); Espiritu Santo. --- In aureizona 



ornaia. ^ Btlr . the band of the hindwing is altogether absent above, and in oniata Stick. (132 e) it is only indicated at 



the end in the middle of the inner margin. These forms are not bound to certain countries, but they occur 



everywhere in the range extending from Guiana to South Brazil. Beneath often with a blue reflection. Single 



and local, though not very rare. 



29. Genus: l£iodilia Ww. (= Erycina Hbn.). 



Approximating the preceding genus in the exterior, but the basal part of the costa somewhat protru- 

 ding,; in the hindwing the middle of the border between the lower radial vein and the upper median is some- 

 times angled or even lobate. Easily recognizable by the colouring and by the sides of the abdomen not being 

 voiriegated, whereas in Panara they are brightly coloured in orange. Few species are known and distributed 

 from the northern coast of South America to Peru, Bolivia and Ai'gentina. Like the Panara, they fly in the 

 sunshine and preferably settle down, with half-opened wings (about like our Chnjso'plianus phlaeas) on fern- 

 fronds and low leaves of Canna. They belong to the more common Erycinidae. 

 lysippus. R. lysippus L. (132 e). Extremely variable regarding size, orange band arid white dotting. Black; 



above on both wings, from the costa to the anal angle, there runs a generally broad orange band; disc studded 

 with light dots. The orange band may be as thin as a thread (in some places of Venezuela) or also very 

 lysias. broad (= lysias Sticii. 132 e); then it is sonietimes proximally shaded in Avhite or filled up with white. — 

 A form, entirely black above and beneatli, without an orange band and with hardly noticeable dotting flies 

 negrita. near Bolivar in Venezuela; it is negfita jorm nov. (132 e). — In Colombia flies a very small, scarcely dotted 

 ' - erratica. form with conspicuously uniformly bent, narrow bands, which I denominate erratica jorm. nov. (132 e) and 

 ■which one might rather take to the following species at first sight. Typical lysippus chiefly occur in Guiana 

 and on the Amazon; near Humayta on the Rio Madeira they are very intensely dotted, at the same place 

 where also Amarynthis meneria fa. superior (132 g) has the widest bands and the whitest spots. 

 lysippoides. R. lysippoides Berg (132 e, f). In shape and colouring very m\ich like the preceding, but smaller, lighter 



brown and without the light dotting. In specimens from Argentina, where I often came across this species 

 in the agricultural park near Palermo on the Silver River, the small band of the hindwing is confined to 

 the inner marginal part of the wing; in specimens from South Brazil it is better developed and also that 

 on the forewing broader. This form also shows alreadj' the marks of the light dotting and thus forms a tran- 

 crioeus. sition to lysipjms; I call it crioeus form. nov. (132 f). 



lycisca. R. lycisca Heiv. (132 f). — HewitsoN figures 3 forms of this butterfly all of which occur, though not 



so often, in the same district, but mostly separated according to the flying-places. STicin':L denominates each 

 form, the rarest one (both wings with an orange band) as the type. The form without the band of the fore- 

 refracia. wing he calls refracta (132 f), the insignificant transition with an incomplete band of the hindwing infirmata. 

 inftrynaia. j^ ^^gg ^j^ggg names be maintained, especially also those unhanded specimens would have to be denominated, 

 in which also the marginal band of the hindwing has disappeared e.vcept some scattered traces of it. Often 

 the two bands are simply indicated at the ends bj' spots. South Brazil, Sao Paulo and Rio Grande do Sul. 

 lysistraitis. R. lysistratus Burm. is said to be confined to Argentina and South Brazil and constantlj^ to differ from 



JiieiiM. the Po-raguay-form luctus Berg (132 f). But also the latter varies, particularly with respect to the costal mar- 

 ginal spot of the foiewing which may be yellow or white, oval or in the shape of a small band. Not rare. 

 As to the form pelta Schs. cf. Additions. 

 lysimachiis. R. lysiniachus iS^ic/). (142 f) has the habitus of the preceding species, but the margin of the hindwing 



is very much lobated, the orange band running through the whole forewing. Neu-Freiburg (South Brazil). 



30. Genus: Ijjmuas Blch. 



Easily recognizable bj' the verj^ long forewings with a rather steep distal margin and short hindwings 

 with a round margin. The body is of a clumsy structure, often with scarlet or orange markings, the head 

 stout with projecting palpi being, however, only in single species so long that they become visible from above. 

 Antemiae thick, quite gradually thickened to weak clubs. The butterflies are mostly black with a red, yellow 

 or white oblique band of the forewing or a variegated border of the hindwing; often also the apex of the lore- 

 ^ying is yellow or white, The veins are in some species very conspicuous, projecting from the veh' ety -black 

 ground. Beneath some species exhibit a faint blue reflection (e. g. L. passiena), above not. Only few species 

 deviate from the general colorial type owing to mimetic influences (e. g. L. tJiyatira). The larva is said to 

 be hairy (Boisduval), the pupa stretched similarly as an Acraiin, with light colours and dark spots, small 

 IJrotuberances on the back of the abdomen. The imagines drmk early in the morning from wet stones and 



*) By a mistake the band of the hindwing of eclypsis was depicted in yellow on our figure; the artist had probably 

 thought that it was discoloured by oil, and had corrected it according to another specimen: the yellow on the hindwing is in 

 fact entirely covered by black scales.
