658 RIODINA- LYMNAS. By Dr. A. Settz. 



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



oriiata. Btlr. the band of the hindwing is altogether absent above, and in oriiata 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 occin^ 



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



and local, though not very rare. 



29. Genus: ISioclilia Wu-. (= Erycina Hbn.). 



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

 dino-; 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 

 variegated, 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 A^rgentina. Like the Pnnara, they fly in the 

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

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

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



above on bf)th 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 

 lyshis. broad (= lysias Sticit. 132 e): then it is sometimes proximally shaded in white or filled up with white. — 

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

 iirrjrUa. near Bolivar in Venezuela; it is negrita form nor. (132e). — In Colombia flies a very small, scarcely dotted 

 crratira. form with conspicuously uniformly bent, narrow bands, which I denominate erratica form. 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 arc very intensely dotted, at the same place 

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

 lysippn},h-s. R. lysippoides Berg (132 e, f). In shape and colouring very much 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 foim also shows already the marks of the light dotting and thus forms a tran- 

 rriodi.^t. sit'on to lysippus; I call it crioeus iorni. nov. (132f). 



lycisca. R. lycisca Hew. (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. Stichel 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 (132f), the insigniiicant transition with an incomplete band of the hindwing infirmata. 

 injirmciia. ^^ case these names be maintained, especially also those unhanded specimens would have to be denominated, 

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

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

 hjsistralus. R. lysistratus Bur7n. is said to be confined to Argentina and South Brazil and constantly to differ from 



Ixclx.-i. the Paraguay-form hictus 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 peltn Schs. cf. Additions. 

 hiM-n,iarlnif<. R. lysiniachus *%:c/;.. (142 f) has the habitus of the preceding species, but the margin of the hindwing 



is very muc h lobated, the orange band ruiming through the whole forewing. Neu-Freiburg (South Brazil). 



30. Genus: £<yiuua>s Bkh. 



Easily recognizable b}^ the very 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. 

 Antennae 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- 

 wing is yellow or white. The veins are in some species very conspicuous, projecting from the velvety black 

 ground. Beneath some species exhibit a faint bltie reflection (e. g. /.. passiena). above not. Only few species 

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

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

 protuberances on the back of the abdomen. The imagines drink early in the morning from wet stones and 



*) By a mistake the band of the Iniulwiiig of cHi/psis was depicted in yellow on our figure: the artist liad ijrobably 

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

 fact entirely covered bv black scales.
