and below it there are arcuate nooses, violetta exhibits on the forewing the distal marginal part and on the 

 hindwing a sector in the cj of a wonderful steel-blue lustre; one may tiu-n, however, the butterfly in the sun 

 in such a way that the whole sru'face of the wings shines also violet. From the Upper Amazon (Tapajoz).

 and in tarinta Schaus (110 A f) from Colombia this median stripe runs through uniformly and in a straight tarirda. 

 line. This species is beneath very bright ochreous yellowish-red and the reflection of the upper surface at the 

 distal margin very intense and extending almost as far as to the centre of the wings; it lies before me from 

 Muzo ; in some places the distal marginal eye-spot of the under surface likewise exhibits a bright blue reflection 

 in others not. Some of these forms may be justly regarded as distinct species, but one must be very careful 

 in this respect in the Erycinidae. Nearly all the af&as-forms are apparently rather common at their finding- 

 places. 



E. eurysthenes Hew. (142 c). This butterfly resembles above very much E. euoras (121 i) to vthich. eurysthenes. 

 the under sui'face is also very similar. But the ^ is at first sight distinguishable by the blue reflection bemg 

 confined to the distal margins of the wings, and beneath between the brown median band of the forewing and 

 its margin, the fringe of euoras is here replaced by another, distinct band. Ecuador. 



E. eurymachus Hew. Probably only a form of the preceding forming the transition to ettoras. Beneath eM)•^/»^ac7^««. 

 the bands of the forewing are duller, more shadow-like, and above in the ^ the blue reflection is confined to the 

 region before the inner angle of the forewing and the apex of the hindwing. Likewise from Ecuador. 



E. regipennis Btlr. and Drc. (122 b). The ^ greatly resembles above arbas; but beneath the median regijiennis. 

 stripe forms the proximal terminus of a white transverse band, appearing in the $ also above. Costa Rica; 

 the specimens lying before me were taken in May near Esperanza. — eupepla G. and S. (122 g) from Panama eupepla. 

 and Colombia exhibits in the male no white band beneath, so that there remains as a difference from arhas 

 only the straight running median line on the under surface of the hindwing. — The regipennis-ioTias are sup- 

 posed to be very closely allied to the arbas-group, and both the forms would produce a very great number of 

 forms, when distinguishing the extension and position of the blue reflection and the colouring of the under 

 surface, since especially the $5 vary almost at every finding- place being sometimes quite grey, or white banded 

 or also nearly c^uite white. 



E. anica H. Schdff. (121 i). This animal, not known to me in nature, is said to come from Surinam; anica. 

 it is described as a (J, but still it is probably a $. Forewings with a white small oblique band, liindwings with 

 a white distal dot. Under surface almost exactly as in the 5 of arbas, but the forewing has a honey-coloured 

 stripe at the base of the costa. 



E. cubages Hew. (121 i). This form of which the (J is unknown, probably belongs as $ to one of the eubages. 

 arbas-iovms some of which have very light $$ which, however, Ave know only from few finding-places. As its 

 patria the ,, Amazon" is only mentioned. 



E. eunaeus Hew. (122 a). Beneath marked like a very small regipennis, but M'ithout the AA'hite band, eunaexis. 

 though with a very distinct marginal eye-spot. Forewing above with an orange oblique spot. From the Amazon. 

 Only the figured specimen, a (J without its exact habitat being stated, is lying before me. 



E. dolichos Stgr. (122 h). Quite peculiarly black and white, beneath with submarginal spots and a doUchos. 

 dark marginal eyespot before the middle of the border of the hindwing. From Pebas and Iquitos on the Upper 

 Amazon. 



E. lisias Cr. (= salimba Godt.) (121 h, as ,,lysias"). In the ^^^ of the typical species the anal angle Usia-i. 

 of the hindwing is extended into a round point. Above the wings exhibit a magnificent blue reflection with 

 white fringes and a black apex of the forewing. The $ is much rarer and its bliie reflection is duller, on its 

 under surface a brown linear stripe runs parallel to the border. Guinea, Colombia, Amazon, to the south as 

 far as Bahia, locally not rare. Varies considerably even at closely adjoining finding-places. The liindwings 

 may end much more obtuse than in the figure (forma lycaeus Stgr., 121 h) or still more pointed; in the latter lycacus. 

 case the small white dots of the under surface being typical for genuine lisias may be also absent; the latter 

 form Statjdikger denominates lysimachus (= lysiniacus Mengel) (121 h, as ,,lisimachus"). Besides, the line lysimachus. 

 of the under surface of the $$ may also occur in the (J and the ground-colom' of the under surface may be 

 brown (euroinus Hew., 121 g); the blue reflection may have a different extension; January-specimens fi-om euromus. 

 Ega (fa. lycaeus) exhibit on both surfaces an orange-red proximal margin of the hindwing and so on.
