as in the other species of the /aértes-group. This band is downwards reddish-brown and towards the apex bor- 
dered by a broad dark grey region and towards the anal by a somewhat narrower reddish-brown region. Chiriqui, 
Central America. Mr. RozBER presumes that there exist two temporal forms of P. lygia, and writes about 
it: ,,Of this magnificent animal I possess 1 g from Chiriqui which corresponds well above with the figure in 
Tris 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 premature to denominate this form, because it is just as well possible that lygia varies in 
one and the same generation. These questions could be decided only by means of further ample material 
with the dates of-the captures.‘ 
P. pheridamas, an entirely isolated, extremely constant species, without any close allies, bearing 
about the same relationship to the group of P. laértes as P. chalciope and P. lycomedes to the series of P. demo- 
phon. 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; 2 with a somewhat strangulated and duller blue band and a 
larger apical spot beneath which there are, as a rule, one or two blurred, 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 
Brazil. pheridamas Cr. (112 a), depicted according to a 3 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 
the whole Upper Amazon and Peru. — phila Frufst. (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 
silvery white spots. Minas Geraes, Espiritu Santo, very rare. — attalis subsp. nov. is based upon 9° from Bolivia, 
which Mr. Fasst has sent from there. The blue bands of the upper surface are narrowed, and the under surface 
is preponderantly coloured in grey instead of yellow. 
P. deiphile Godt., the best-known of the variegated species, inhabiting Central Brazil. I have before 
me specimens from Espiritu Santo, and v. BOENNINGHAUSEN knew Petropolis in the Organ Mountains as their 
habitat. The upper surface resembles P. vwenagoras-3 (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 Q a grey or whitish violet diffuse spot. Under surface reddish-brown, otherwise like in xena- 
goras (113 a). 
P. xenagoras Hew. (113 a $9) differs somewhat in the extent of the violet part of the forewings of 
the 99. Thus I possess a specimen with almost entirely brown forewings exhibiting but a faint violet lustre. 
The 9 is 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 3 there is only yet a narrow stripe of 1 em 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 g, on the hindwing also the 3 most proxi- 
mal ones exhibit black dots between the ocelli, which are lacking the g. The costal margin of the forewing 
being faintly indicated yellowish-brown in the g, is much more sharply and distinctly prominent in the Q, as 
well as the white fringes of both the wings. The under surface analogous to the 3 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. Ropert BrepERMANN according to specimens of his collection. 
P. garleppiana differs from P. xenagoras by the appearance of a light blue band of the upper surface 
of the forewings. We have to distinguish two territorial forms: garleppiana Sigr. (112 d 3, 113 a 9) from Bolivia. 
The 2 was discovered by Fasst and described as follows: very different from the P. xenagoras-2; especially 
of a considerably larger size (expanse of wings 106 mm). Upper surface likewise of a dull black, but the violet 
reflection of the g is absent and there remains only the blue, very narrow Prepona-band, 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 quite 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
