498 PERISAMA. By J. Rober. 



lines between which there are 3 to 5 very small (sometimes missing) black dots. — Specimens with a brown 

 hahneli. under surface were described as hahneli Stgr. 



oppdii. P. oppelii Lrifr. ( 102 A e. f ) fi'om Colombia has a sulphur-yellow under surface with 2 black lines on 



viridhiota. the hind wines. In viridinota Btlr. from Peru the blue band of the upjDer surface of the hind wings has disappeared 



except some few little scales. The $ has somewhat rounder shape of the wings. 



emincns. P. etilinens Oberth. has above a broad yellow band of the hindwings instead of the blue one, but does 



not differ from oppelii beneath. It is presumably not a species of its own, but only a remarkable aberration. 



comnetia. P. coiiinena Hew. (102 Af) from Peru has an ochre-yellow-under surface of the hindwings and a large 



red basal spot of the forewings, thus resembling huinholdtii , but between the black lines of the under surface of 

 the hindwings there are no dots. 



xanthica. P. xanthica HeuK (102 A f) from Peru has black upper surface of the hindwings and deep-yellow under 



surface with 2 nearly parallel black stripes. 



nyctimcnc. P. nyctinicne Heu\ (102 A f) from Ecuador has the forewings marked similarly as in himiboldtii, but 



on the distal margin of the hindwings only 4 sphenoidal blue spots, the under surface of the forewings being 

 black with brown basal strijje and brown apex of the wings and 2 white spots at the costal margin; the 

 under surface of the hindwings is yellowish-brown with a dentate submarginal line and a black, little curved 



tnstrhjosa. median line between which there are 5 black dots and several submarginal white streaks. — In tristrigosa Bth. 

 from Peru the black dots on the under surface of the hindwings are absent. 



cloelia. P. cloelia Hew. (= oehreipennis Bth.) (102 A f) from Peru is most conspicuous by a large blue spot 



at the proximal margin of the forewings, whicli are besides provided with a blue basal stripe and a subapical 

 spot; the hindwings have a faint blue band of the distal margin. The under surface has almost the same mar- 

 kings as in oppelii (102 A e), but deeper yellow. 



iryphoKi. P. tryphena Hen\ (102 A f) from Colombia has a large yellowish-green spot on the forewings, which 



is adjoining to a basal stripe of the same colour, a yellowish-green spot at the costal margin and a small 

 bluish apical spot. The hindwings have a bluish-grey marginal band and a yellowish-green median spot. The 

 under surface resembles that of oppelii, but is paler yellow, and between the 2 black lines there are also several 

 small black dots. 



vifrlmja. P. vitringa Hew. (102 A g) from the Upper Amazon has a similar but still paler under srrrface tlmn 



tryphena, the black upjjer surface has a yellowish-green band nearly of the same width and leads from the 

 costal margin to the inner angle, as well as 2 blue rays at the base of the forewings and a distal-marginal band 

 consisting of 4 greenish-blue small spots. 



camcll/a. P. canielita Hew. from Bolivia shows a greenish-blue median band reaching from the costal margin 



to the inner angle, broad blue basal stripe and rather large blue apical spot of the forewings; the hindwings 

 exhibit a very broad bluish-green marginal band decreasing in width from the costal margin to the inner angle, 

 and some few blue scales in the centre. The under surface is quite similar to that of humholdtii. 



lebasil. P. lebasii Guer. (102 A g) from Colombia is striking for the blue rays on the hindwings, which are in 



ttci/riiKi. negrina form. nov. from the Upper Rio Negro onljr alluded to. In this form the greyish-green band of tlie hind- 

 wings is also broader, the lustrous blue band of the forewings, however, narrower. 



lanice. P. laiiice Heiv. (102 A g) from Ecuador and Peru is above very similar to a little bonplandii, but the 



green band of the forewings is narrower and dentate on both sides. The under surface is cpiite different, as 

 is shown in the figure. 



vioronina. P. nioronina Stgr. i. I. from Peru (Chanchamayo) is somewhat larger than lanice, above hardly differing 



from it, the under surface of the hindwings, however, is darkened to such an extent that, except the light colou- 

 ring jjlaced distally to the outer dentate line, only anelongatedtriangular spot distal to the inner black line at the 

 costal margin and some very little spots in the centre remain light; the inner, proxiinally red-edged line i.s much 

 less curved than in lanice and black discal dots are absent. The under surface of the forewings has more red 

 colouring on the basal part and a complete middle row of blue spots. 



oucrini. P. gueritii Fldr. (102 A g) from Colombia has almost white under surface of the hindwings; the red 



stripe at the costal margin of the hindwings may also be absent or only indicated; at the basal part of the under 

 surface of the forewings there may be a red spot instead of a blue one. 



vanlnka. P. vaninka Hew. (102 A g, h) from Colombia and Peru differs from the similar species by a red stripe 



at the costal margin of the upper surface of the hindwings and by pure blue bands. The $ is hardly different.
