quite faintly indicated. The $ seems to me to be an entirely white butterfly which was figured on the table 



riis.iata. as chionea, benause Salvin and Godmaiv included a yellowish-red, broad black-bordered butterfly (russata 



G. and S.) (122 d as gyda-'^) as the $ to gydn. This latter one occurring with a red-brown, yellowish-red and 



pale yellow upper surface, belongs, however, according to the under surface into the group of eucrates-leucorrlioea, 



it may be the legitimate $ of one of them, gyda is a dubious species; the under surface is not figm-ed in 



Hewitson's work and the type is lost. The upper surface varies in the tinge being sometimes brownish-red 



ictm. (ab. tetra nov.), sometimes more yellowish-orange; the $ may be faintly shaded in grey at the base pnd the 



border of the hindwing. The butterfly seems to be distributed over the whole tropical South America, though not 



common and \ery local; it occurs from Central America through Colombia and the Amazon as far as Bolivia. 



In the north of the range the $$ exhilnt the purest white, in the south they are slightly darkened in greyish, 



especially in the basal part of the wings (? = cJiirone Hew.). 



praechira. E. praeclara Hew. (122 d). ^ above about like gyda-^, but the wings are of a wonderful green, golden 



red and purple silky lustre, as we have described it in a detailed manner on p. 617. Under surface silvery 



white with some dispersed, small brown spots in the disc of the hindwing. The Upper Amazon District (Iquitos) 



and Ecuador, 9 unknown. 



opaJcsrcns. E. opalcsccns Heiv. Almost like the preceding, also with a magnificent reflection in the colours of the 



rainbow, but the dark margin of the forewing is absent. Seems to be widely distributed like the preceding and 



following species (Amazon to South Brazil), but very rare. I don't know the $. 



opalina. E. opalina Heir. (122 d). Coloured like praeclara, only the yellowish-brown more hazy; but the lustre 



is here more one-coloured brass-yellow and it mostly varies on the whole surface of the wings uniformly to 



golden red or yellowish green. On the silvery white under surface the small discal spots are arranged in the 



direction of the usual median transverse stiipe. From Brazil, probably very widely distributed, but extremely 



rare. The $ is unknown to me. 



euphaes. E. euphaes Hew. (122 d). In the ^ the foi'ewings are above dark red brown, the hind wings orange 



with a dark border and basal ray towards the middle of the border; the latter ray varies in distinctness and 

 colouring. Beneath the darker marginal part is separated from the silvery white basal part by the irregularly 

 indented median transverse line. It apparently flies iii the whole Amazon District, since there are specimens 

 before me from Para and from the Rio Napo. 



iiiicd. E, utica Heiv. (122 c). Shape and under surface almost like in euphaes, but the indentations of the 



median transverse line are not so deep. Above, however, the forewings are also orange-red. with a broad black 

 costal margin and distal margin. I do not know the $. From Brazil ; very rare in the Organ Mountains. Neither 

 v. BoNNiNGHAUSBN nor myself have found it. 



.sKhiirr/nitea. E. subargetitea Lathy (122 c). One of the largest Euselasia, above blackish brown (9 somewhat duller), 



beneath silvery grey; forehead above golden-yellow. Colombia, single. 



tplfrhw. E. teleclus Stall (= gemellus F.) (122 c). Above blackish brown, forewing with a reddish-tinged 



basal part and an orange-yellow discal spot {^), or an ochre-yellow oblique spot ($). Hindwing always with 

 an ochre-yellow sj^ot before the apical part. In typical specimens the under surface, similarly to that of sub- 



cakdettce. a,rgenteri (122 c), silvery grey and distally slightly shaded, but it may also be quite light silvery white (cataleuce 

 Hbn.) (122 c), in which case the basal half of the upper surface is mostly of a brighter red-brown colouring, 

 the orange spot of the forewing running in the shape of a stripe as far as to the base. The transverse line of 



archclaH.'!. the under surface is yellow and almost straight. — archelaus -subsp. nov. (110 A e) is a very large form 

 discovered by Fassl on the Rio Songo in Bolivia, at an altitude of 750 m; here the basal part of the fore- 

 wings is not red-brown and the postdiscal spot of the hindwing is covered by blackish. Also in this form 

 the under surface may be, in its distal part, more shaded or of a purer silvery white. Guiana to Bolivia, not rare.

2. Genus: lEetlioiiolla Ww. 



A genus probably consisting of but one very variegated species being unmistakably characterized 

 already by the conspicuous colouring and the deeply indented margin of the hindwing being continued in the 

 $ at the ends of the veins into teeth-like small tails. On the forewing the subcostal is four-branched; the bran- 

 ches 1 and 2 rise before, 3 and 4 behind the cell. Hindwing without a basal vein. Palpi extremely short. The 

 colouring resembles that of certain Themone, Cartea, Monethe, Aricoris etc., with which conjointly patented 

 butterflies such as Acmeini, Ithomii, Pericopini etc. are imitated. The 99 fire very stout and clumsy which 

 makes them still more similar to the unwieldy Actinote. They belong to the more common Erycinidae, but 

 they are local and seem not to leave their birth-place. Life-history unknown. 

 nriiia. M. ceclUa Cr. (122 i). The first form published by this name is a 9- above bright orange-red with 



a broad black apical part of the forewing, containing a yellow crescentiform band, and a row of yellowish
