a bow round the much larger, yellow-bordered eye-spot. The hindwings beneath, in the ^^ of the Amazon- 

 form also above, with 4 dark streaks and dark margin. Amazon, Peru and Bolivia. 



D. hyphea Cr. (126 f). In this form, being distributed from Cayenne to Peru, though mostly not hyphea. 

 common, the median eye-spot of the forewing is considerably developed, like in a Mesosemia of the preceding 

 group, the distal half of the forewiiigs being suffused with grey and the dark streaks widened to brown bands. 



8. Genus: Meisoplitlialiua Wio. 



Only a branch of the preceding genus, with somewhat differently formed forelegs and palpi (last joint 

 more knob-shaped than coniform), forming a connection of Diophthalma with the maeotis-groxij} of the genus 

 Mesosemia. Especially the ?$ of Mesophihahna are very near to certain $$ of Mesosemia. Only 1 species. 



M. idotea Wiv. (= mirita H.-Sehdff.) (126 e). Ground-colour of the cj light blue, of the $ dirty grey, idoUa. 

 in both sexes with a slightly reddish gloss. The transverse stripes are in the ^ more of the shape of lines, like 

 in Diophfhahna, in the $ more like stripes, like in Mesosemia. Central eye-spot of the forewings -with 3 

 small white dots. The butterflies occur in Guiana and on the Amazon and are not rare. The figured specimens 

 are from Ega. 



9. Genus: Peroplithalnia Ww. 



Small, very delicate butterflies of a dirty yellowish-grey colour with an eye-spot of the forewing stan- 

 ding, however, not in the cell-end, but behind the cell, thus being placed more distally than in Mesosemia. 

 The butterflies have the same habits as the preceding, they are met with singly, though they are not rare. Only 

 1 species. 



P. tullius F. (= tenera Ww.) (126 f, as tullia). Dirty greyish-brown with yellowish and whitish iuUius. 

 shades; before the apex an eye-spot with a yellow ring around it and several pupils. This eye-spot stands be- 

 hind the cell-end, almost like a Satyrid-eye-spot, unlike the more proximally situated eye-spot of Mesosemia. 

 The whitish shades may be developed to such an extent that the whole disc ef the wing turns white. Such 

 extreme forms may be denoted as tenera G. and 8., nee W^v. (? = lasus Dbl.) (126 f), but from the more tmera. 

 than 100 specimens before me it is impossible to form a complete series of transitions (second tullia-iig\xre) 

 to both forms. Thc^e transitions are also confined to habitats, but not to geographical districts, and between 

 habitats with entirely grey specimens there may occur habitats with very light white butteiflies, as for instance 

 near Cachabe. Central and South America to the south as far as Ecuador and the Amazon. Not rare. 



10. Genus: Hypliilaria Hhn. 



This genus contains half a dozen of just as delicate forms as the two preceding genera, but the animals 

 are generally of brighter colours. Mam'' have, similar to the Diophthalma, -wings with parallel transverse stripes. 

 The veins exhibit great variations, being also expressed in the shape of the wings. The margin of the fore- 

 wings is sometimes convex, sometimes curved and the hindwings may be round, or also angled iir the middle 

 or the ma,rgin. The habits are the. same as in Diophthalma. 



H. nicias Stall (= nicon Godt.) (126 g). ^ pale yellow, $ more bone-white, the wings with black jHcia.s. 

 margins and a black oblique band cutting off a light — in the ^ ne«rrower — subapical band-spot from the 

 ground-colour. In Surinam-(J(;J there are often in the black distal margin all kinds of light yello^v markings 

 which are absent in Bolivians. The scheme of coloration being somewhat conspicuous imitates that of a small 

 form from the Danaid genus Scada. From Cayenne to Bolivia, varying somewhat in the width of the black 

 margins and bands; not rare. 



H. anthias Heiu. (126 g). Similar to the preceding, but the whole marginal third or a stUl gr-eater anihias. 

 part of the wing black with chains of light spots, while the black oblique band is absent. Bolivia and Peru. — 

 orsedice Godm. (126 g) is a scarcely differing form in which the small light spots are somewhat more developed, orsedice. 

 especially' beneath ; Colombia to Guiana. 



H. anophthalma Fldr. (126 g). Immediately recognizable by the slightlj^ produced apex of the fore- anopMhal- 

 wing and by the margin of the hind wing being faintly bent. The bone- white disc of the wings is traversed by '"" 



a straight black stripe in the basal third, and one each in the middle of the forewing and hindwmg, so that 

 they meet angularly at the imier ma.rgin of the forewing. Colombia and Ecuador, not rare. 



H. parthenis Ww. (= cydias Dil.) (126 g, as parthenias). (J above drill orange-red, somewhat lighter parihenis. 

 at the costal area. The forewing is traversed by black parallel bands which by far do not reach the mner mar- 

 gin in Bahia-rJ(5^, whereas in Bolivians they extetid with one tip quite close to it (= tigrinella 5fic7i.) (126 g). tigrinetla. 

 in Surinam-specimens where they are besides mostly — though not always — increased, they rea^^h it broadly; 

 this is the form virgatula Stich. (126 g). The $? of these 3 forms scarcely differ; their black stripes always virgafula. 

 traverse all the wings thickly and completely.
