628 EUSELASIA. By Dr. A. Seitz. 



dorina. E. dorina Heiv. (121 i). A very raie butterfly from Teffe on the Amazon. Only the (^ lies before 



me. It is above marlied like oimlina, but also the hind\^ings have a broad black border and the colom' is deep 

 hemochrome instead of yellow. Beneath the hind'nings have sometimes a hemochrome proximal niargin, and 

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

 euhemerus. E. euhemerus Heio. (121 g). Only the $ is known, undoubtedly belonging to one of the (J(J known, 



maj^be to dorina together with which it was taken. Above brown ^^ith an oblique-oval orange spot, 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 broMTi 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. Hbwitsou already was forced to demonstrate 

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

 is -CTTong in correcting Crazier for having figured the wdngs too round, gelanor, however, does not only vary 

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

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

 foremng. The blue ]-eflection 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 (Siuinam)-specimens are those from Bolivia with a violet-brown, 

 almost unmarked under siu-face and a convex distal margin of the forewdngs. 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 (J almost 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 smfaces of a dull bro-miish-grey colom-, without a reflection, the marking is like in the ^■. dots, 

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

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

 extensa. transverse line running somewhat differently; Amazon. ■ — extensa Bates is quite similar to euhotes, larger, the 



hindwings in the (J more prolonged, but not quite as pointed as in uria. Upper Amazon. 

 crotopus. E. crotopus Cr. (= midas Godt.) (121 g). Very variable; above the typical ^ is blackish-brown 



with the disc of the fore-ndng being quite slightly brightened. The under sm'face 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 w^hite. Particularly the punctiform spot before the middle of the hindwing-border is intense, 

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

 greyish brown with dull brightenings in, below and beyond the cell, in the fore-wing, sometimes also on the 

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

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

 crotopina. nov.) — above blackisli-browii, beneath red-brown (crotopina Stgr.). — Forewing with a dull, indistinct orange- 

 mutaior. Spot, hindwing with a magnificent bluish-violet reflection: mutator, form. nov. — Hind-«ing with a sharply 

 rhodogyne. defined oblique orange band, imder surface violettish-brown : rhodogyne Godm. This form occmrs more in the 

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

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

 venezolana. zolana form. nov. (121 g) from San Esteban. Venezuela, has a red-brown gromid-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 occm-s singly, though it is not rare. - — The larva is black with whitish stigmata and fluffy hairs; behind 

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

 and the sides with dark dots. 

 micaela. E. micaela Schs. Wmgs dark violettish-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 margm; under surface light Krown; 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 luniform, 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 

 unkno-mi to me, and from the description it is not be seen, where it is allied to. 

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



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

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

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

 buted, though singly. 

 ihucydidcs. E. thucydides F. (= nycha Hbn., arisbas Dahn. (122 g). Hindwing in the anal part like the prece- 



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

 above with a large orange-spot and beneath of a bro-maish-white ground-colour. 5 above yellowish-grey -with 

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

 DrN'GER also on the Chu-iqui in Costa Rica. 

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



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