P. laertes-gvouY). The peculiar under surface, with abundant tortous and interrui)ted lines, is already entirely 

 of the laertes-clmractev, exhibiting among other marks also the two large a])atur()idal ocelli of the hindwino-s. 

 The character of the upjDer surface is shown by our figure 112c {bakiana), that of the under suiface 112d 

 iproscJiion). The northernmost branch bahiana Fi-uhsl. (112 c) has beneath the greatest likeness \\\\\\ P, fugenes hain,n,a. 

 (112 b), though the ochre-yellow hue in the sulnnedian zone f)f the forewings is absent and the black ])ost-discal 

 interrupted band considerably broader. The specimen figured by us is a $ (no ^J as stated in the table). The 

 blue area of the upper surface throughout paler than in the more southern forms. From Bahia in my 

 collection. — santina Fruhst. beats the Bahia-race in its size; the l>lue zone of the upper surface remains darker, fim/hia. 

 besides of a more intense lustre, and in the ^i^ there is always a forewing-band going as far as to the costal 

 margin. The under surface differs from hnhiann by a darkening of the submarginal zone of both the winffs 

 similar as in proschioti. Espiritu Santo. — pylene Heic, an extremely rare form resembling santina, though inil'»<\ 

 it has no transcellular blue spots of the forewings, the under surface being always overhued by reddish 

 instead of grey. — miranda !^tgr. resembles pylene from which it is only distinguished by the presence of sub- mimiula.

 menau in Coll. Feuhstorper. — proschioti Fnihst. (II2d) forms the extreme with the narrowest bands among i>r<>sr/,ioH. 

 the collective specie-f. I have sjiecimens at hand with scarcely half as extensive blue band of the upper surface 

 as we find it in b'ihian%. The transcellular spots are absent as a rule, though there aie ^(^ as well as 90 with 

 small blue splashe-, but also as a i-arity $9 v,'M\ 3 imposing maculae. The under surface is decidedly paler 

 brown than in nuranda, and the submarginal heart-spots consideralily smaller. Rio tirande do Sul, very rare 

 especially in a good condition: but there are 11 q,j*. 6 $$ i'l Coll. Fruhstorfer *). 



P. eugenes differs from P. pylene above by the light yellow hair-tuft. Some local races are, hoM-- 

 ever, so closely allied with P. pylene that I did not yet recognise it in 1904. The most essential mark is formed 

 by the pregnant silver-spotting of the under surface being distally bordered by the small median black strokes 

 of the forewings. The submarginal reniform or cordiform spots of the forewings are smaller and scarcer than 

 in pylene. P. eugenes is more widely distributed than pylene. It is met from the Amazon to Bolivia and Para- 

 guay, and in South Brazil as a great rarity in Santa Catharina. The most noted geographical race is eu»enes <ii,ini<s. 

 Bates (112 b). The (J has above very nearly the appearance of laertes Hbn. the blue bands of which are. how- 

 ever, on the forewings costally somewhat broader. The colour of the band is in the middle of a greenish lio-Jit- 

 blue which turns dark-blue at the margin. Otherwise the wings are unicolorously jet-black. Under surface: 

 The wing-ba-ie is of a silvery white, as well as the apex of the cell and a cliscal row of 5 very irreoular white 

 spots being proximally bordered in broad black. At the base we notice a broad black semi-circle surroundino- 

 the precostal, and being similar though fainter in pylene btiliiana Fnihst. and pylene santina FruJisf. On the 

 hindwings we notice towards the apex a black streak, and between the ocelli there are 3 light-blue dots. Anal 

 and subanal region of the hindwings densely set \\ith fine white scales. Ground-colour of the wings yellowish- 

 grey, but the centre of the fore\^'ings is traversed by a yellowish-brown region from the base into the anal angle. 

 Palps and feet above black, below white.. Eyes reddish-brown, antennae black. Head and thorax above black, 

 below whitish-grey. Abdomen above black, below yellowish-grey. The $ exhibits above a somewhat broader 

 blue band than the ,^, and also at the costal margin beyond the cell a large roundish blue macula. Occasionally 

 there are also two small blue dots to be noticed yet beyond the cell. The under surface of the wincrs is .--ome- 

 what more profusely white, the ground-colouring predominantly light yellowish-brown and on the hindwings 

 the silvery white scales are concentrated to a distinctly noticeable submarginal band. The ocelli are distally provi- 

 ded with broader white ringlets. Known from Surinam, the Lower and Upper Amazon. Fassl has discovered rj,^ 

 on the Upper Rio Negro at an altitude of 800 m. — simois Fldr. an extremely rare territorial form of Western Co- .simnh.

 more greenish blue, has larger silvery-white spots of the under surface of the forewings than e«^eHe.b\ — decorata (U'c.raia. 

 Fruh.st. forms an intermediary between eugenes diluta from the Amazon, eugenes Bates and laertides Stgr. from Pa- 

 raguay. (J: On the forewings the blue median band grows narrower in an upper direction, being continued to the 

 costal margin in the shape of 3 small blue spots. The under surface of all the wings much lighter, the ground co- 

 lour grey and only in the discal area and anal angle of the forewings yet loam-yellow. The dii^fcal silvery bands 

 of both the wings broadened and coherent, thus not consisting of isolated spots as in eugenes. Furthermore, 

 the whole hindwing-cell is covered with silvery white scales, while in eugenes only the cell-apex apeais covered 

 with silver. All the black i;igzag-bands are greatly reduced. The marginal zone of the hindwings throughout 

 with greyish-white scales, while in eugenes there are only in the anal angle some white dots seen. $; considerably 

 larger than the eugenes-'^, decorated with duller blue bands being prolonged towards the costal margin in the 

 shape of 3 broad blue dots. Under surface lighter than in eugenes, and decorated with broader silvery spots 

 in the cell as well as in the discal area. The under surface of the hindwings still more profusely decorated, 

 since the discal and basal silver-spotting is confluent in it, forming one single region. The discal zigzag- 

 lines greatly reduced like in the ,^, instead of it the internerval sul)marginal ccjrdiform spots of the under
