628 EUSELASIA. By Dr. A. Seitz. 



aorhia. E. dorina Hew. (121 i). A very raie butterfly from Teffe on the Amazon. Only the (J lies before 



me. It is above marked like opalina, but also the hindwings have a broad black border and the colour is deep 

 hemochrome instead of yellow. Beneath the hindwings have sometimes a hemochrome proximal margin, and 

 the black punctiform spot before the middle of the border is shaded snow-wliite. 

 etihcpicrus. E. euhcmerus Hew. (121 g). Only the $ is known, undoubtedly belonging to one of the rS<S known, 



maybe to dorina together Avith which it was taken. Above brown -with an oblique-oval orange sjjot, beneath 

 similar to dorina. Amazon. 

 gelanor. E. gclanor Cr. (121 h). Above blackish-brown, with a blue reflection, beneath ochre-yellow with a 



brown transverse line and brown dots before the border. Among the 22 specimens of my collection there are 

 hardly 2 alike, so very great is the variability of the species. Hewitson already was forced to demonstrate 

 by two figures of the under surface that the transverse line on the forewing may be absent in the ^. But he 

 is wrong in correcting Cramer for having figin-ed the wings too round, gelanor, however, does not only vary 

 in the marking and colouring, but also very much in the wing-contour, and there are such with a prolonged 

 and with a round hindwing, with a dentate and smooth border, with a straight and bulged-out border of the 

 forewing. The blue reflection is mostly placed in the distal-marginal region, but it may also be almost absent 

 or extend all over the wing. In some specimens it is extremely bright, of a Prussian blue, in others again dull 

 and violet. Greatly deviating from typical (Surinam)-specimens are those from Bolivia with a violet-brown, 

 almost immarked under surface and a convex distal margin of tlie forewings. In Guiana common; in devia- 

 ting specimens distributed as far as Bolivia. — Near Pebas on the Upper Amazon there fly specimens with 

 very long-stretched hindwings and an under surface exhibiting in the ,^ almo.st the same markings as in the $; 

 uria. this is uria Hew. They have only quite a faint violet reflection at the border of the wings. — The ?? of gelanor 

 are on both surfaces of a dull Ijrownisii-grey colour, without a reflection, the marking is like in the ^J : dots, 

 euholcs. a transverse stripe and the shade more dense. — eubotes Hew. (121 h) is if it is at all of a different species, 

 very closely allied to gelaTwr; the upper surface is the same, the under surface more violettish brown and the 

 e.i-te,i.sa. transverse line running somewhat differently; Amazon. • — extensa Bates is quite similar to eubotes, larger, the 



hindwings in the ^ m.ore prolonged, but not cpiite as pointed as in uria. Upper Amazon. 

 croiopus. E. crotopus Cr. (= midas Godt.) (121 g). Very variable; above the typical c? i'"* blackish-brown 



with the disc of the forewing being quite slightly brightened. The under surface is earthy grey with a transverse 

 stripe running similarly as in gelanor (121 h) and dorina (121 i), and with dots before the border which are partly 

 outside bordered in white. Particularly the punctiform spot before the middle of the hindwing-border is intense, 

 often angular, and above the anal angle of the forewing there is mostly a distinct shadow-like spot. $ dark 

 greyish brown with dull brightenings in, below and beyond the cell, in the forewing, sometimes also on the 

 hindwing. The following forms occur in the ^ being, however, connected with each other by transitions and 

 ater. probably bound to certain finding-places (not countries) : Above jet-black, beneath blackish-brown (ater form, 

 crotopina. nov.) — above blackish-brown, beneath red-brown (crotopina Sfgr.). — Forewing with a dull, indistinct orange- 

 mutator. Spot, hindwing with a magnificent bluish-violet reflection; mutator, jorm. nov. — Hindwing with a sharply 

 rhodorjyne. defined oblique orange band, under surface violettish-brown : rhodogyne Godm. This form occurs more in the 

 northern districts (Central America, Colombia) and the $ is above colomed just like the ^. — All the 4 wings 

 psammathe. with a large orange-spot, the ground-colour of the under surface whitish-grey: psammathe fcr^n. nov. — vene- 

 venezolana. zolana jorm. nov. (121 g) from San Esteban. Venezuela, has a red-brown ground-colour. The species is distri- 

 buted from Central America through the whole northern part of South America, to the south as far as Bolivia ; 

 it occurs singly, though it is not rare. — The larva is black with Avhitish stigmata and fluffy hairs; behind 

 the head there is a hemochrome transverse spot out of which there rise two points; the pupa is green, the back 

 and the sides with dark dots. 

 micaela. E. iTiicaela Schs. Wings dark violettisli-brown, on the forewing a large, yellowish-red spot behind 



the cell from vein 2 as far as above vein 4, not reaching the distal margin; under surface light brown; a 

 reddish-brown median line near the costa of the forewing shaded by black, close at the inner margin of the 

 hindwing curved; a large subterminal shade, on the forewing Inniform, on the hindwing dissolved into spots, 

 containing 2 black dots between the veins 3 and 4; a faint dark distal shade. 32 mm. Peru. The species is 

 unknown to me, and from the description it is not be seen, where it is allied to. 

 eiKjeun. E. eugeon Hew. (122 f). Above black, beneath very dark greyish-brown, recognizable by the anal 



part of the hindwing being prolonged like a point. The transverse line of the under surface runs irregularly, 

 and in each of the specimens before me originating from different districts, differently, in northern specimens 

 (Amazon) more straight, in southern (Argentina, Bolivia) almost semicircular. $ larger, lighter. Widely distri- 

 buted, though singly. 

 thurydidvs. E. thucydides F. (= nycha Hhn., arisbas Dalm. (122g). Hindwing in the anal part like the prece- 



ding species prolonged to a point, transverse line of the under surface also similarly running, but all the wings 

 above with a large orange-spot and beneath of a brownish-white ground-colour. $ above yellowish-grey with 

 dark distal margins and median spots. South Brazil, where it is not rare near Petropolis; according to Stau- 

 DINOER also on the Chiriqui in Costa Rica. 

 eurypus. E. angulata. We distinguish 3 subspecies: eurypus Hew. (122 e), above entirely one-colovued deep 



blackish-brown; beneath the transverse stripe is distally shaded in dark, behind it on the hindwing another
