564 PREPONA. By H. Fruhhtorfer. 



as ill the other species of the laertes-grou]). This band is downwards reddisli-brown and towards the apex bor- 

 dered by a broad dark grey region and towards the anal by a somewhat narrower reddish-brown region. Chuiqui, 

 Central America. Mr. Roeber presumes that there exist two temporal forms of P. lygia, and writes about 

 it: ,,0f this magnificent animal I possess 1 (J from Chiriqui which corresponds well above with the figure in 

 Iris XVII, Table VI, fig. 2. The under surface, however, is considerably different, since instead of the cunei- 

 form white submarginal spots of the forewings there is only a blurred whitish band slightly contrasting with 

 the ground-colouring, and the black band before it is very much serrated, similarly as in eugenes Bates, but 

 the submarginal cordiform black markings in eugenes are in my specimen of lygia represented only by three 

 white dots being encircled by a thick black. It might be possible that this form though entirely deviating belongs 

 to another generation but the specimen according to which Mr. Fruhstorfer has described this species. 

 But it would be prematm-e to denominate this form, because it is just as well possible that lygia varies in 

 one and the same generation. These c[uestions could be decided only by means of further ample material 

 with the dates of the captures." 



P. pheridatnas, an entirely isolated, extremely constant species, without any close allies, bearing 

 about the same relationship to the group of P. laertes as P. chakiope and P. lycomedes to the series of P. demo- 

 ■plwn. Clasping-organs considerably shorter than in the allied species, the phyteuma-like club at the uncus 

 remarkably stunted, valve extremely densely set with long black bristles. Upper surface distinguished by 

 an uncommonly broad blue magnificent area; $ with a somewhat strangulated and duller blue band and a 

 larger apical spot beneath which there are, as a rule, one or two blmred, insignificant maculae embedded. The 

 under surface varies according to the habitat of the butterflies from light loam-yellow to effaced greyish brown. 

 We so far know only three territorial forms extending from Colombia to Bolivia, and from Guiana to Central 

 plur'iditiiuis. Brazil, pheridamas Cr. (112 a), depicted according to a ,^ from Surinam. The form remains unchanged in spite 

 of its extensive range, and beside the specimens from Cayenne, Surinam, Obidos, Mato Grosso and Ecuador 

 of my collection there are also specimens known to me from Villavicencio in East Colombia from 400 m, from 

 pkiki. the whole Upper Amazon and Peru. — phila Fruhst. (112 a) surpasses pheridamas in the extent of the blue 

 magnificent spots of the upper surface; the preapical macula also appears nearly again as large. The under 

 surface differs from pheridamas by a more reddish-yellow upper surface being more profusely decorated with 

 attalis. silvery white spots. Minas Geraes, Espiritu Santo, very rare. — attalis subs p. nov. is based upon $9 from Bolivia, 

 which Mr. Fassl has sent from there. The blue bands of the upper surface are narrowed, and the under surface 

 is preponderantly colom-ed in grey instead of yellow. 

 (kiphMc. P. deiphile Godi., the best-known of the variegated species, inhabiting Central Brazil. I have before 



me specimens from Espiritu Santo, and v. Boennikghausen knew Petropolis in the Organ Mountains as their 

 habitat. The upper surface resembles P. xenagoras-<^ (113 a), but the black costal dot in the series of orange- 

 yellow spots of the hindwings is absent. The violet zone of the upper surface more extensive, and beyond the 

 cell there is in the $ a grey or whitish violet diffuse spot. Under surface reddish-brown, otherwise like in xena- 

 goras (113 a). 

 xcnaijora^. P. xcnagoras Hew. (113 a o?) differs somewhat in the extent of the violet part of the forewings of 



the 9?- Thus I possess a specimen with almost entirely brown forewings exhibithig but a faint violet lustre. 

 The 9 i'^ generally by one third larger than the rather large 3* of this species. The black of the upper surface 

 somewhat more subdued. Of the magnificent violet of the (^ there is only yet a narrow stripe of 1 cm width 

 left on forewings and hindwings, being more profoundly dark ultra-marine blue and bordered indistinctly. 

 The yellowish-brown submarginal spots nearly again as large as in the rj. on the hindwing also the 3 most proxi- 

 mal ones exhibit black dots lietween the ocelli, which aie lacking the ^. The costal margin of the forewing 

 being faintly indicated yellowish-brown in the 3^, is much more sharply and distinctly prominent in the 9> as 

 well as the white fringes of both the wings. The under surface analogous to the (^ of a deep dark rust-brown ; 

 the white enamel spotting just as conspicuously prominent. Bolivia. The figures of this species were depicted 

 by the directions of Mr. Robert Biedermann according to specimens of his collection. 



P. garleppiana differs from P. xenagoras by the aiipearance of a light blue band of the upper surface 

 ijarUpiiiinni. of the forewings. We have to distinguish two territorial forms : garleppiana Stgr. ( 1 12 d (J, 113 a 9) from Bolivia. 

 The 9 was discovered by Fassl and described as follows: very different from the P. xenagoras-'^; especially 

 of a considerably larger size (expanse of wings 106 mm). Upper surface likewise of a dull black, but the violet 

 reflection of the ^ is absent and there remains only the blue, very narrow Prepona-h&wd, very short in the 

 forewing, reaching upwards only to the anterior median, being downwards widened and terminating at the 

 proximal margin, bent somewhat proximally; it is, therefore, not identical with the cpiite differently coloured 

 and shaped band of the 9 of xenagoras. In the hindwing the blue band corresponds to that of the ^J, the violet 

 reflection likewise absent. The yellow submarginal spots of the forewing similar to those in the 9 of xenagoras; 

 costal margin, however, far less intensely yellow. The submarginal macular-band of the hindwing obviously 

 differing from that of the 9 described above, the two eye-spots on both the surfaces nearly again as large, but 

 the 3 interjacent yellow spots of the band not black eye-spotted as in the former; on the under surface these 

 spots show through, though but in the shape of 3 whitish-blue, minute dots. The brown colour of the under
