wings. The blue basal area of the forewings is slightly intermixed with black. The under surface is brick-red 
and in the green distal area there stand three series of entirely black spots. — Near Yurimaguas and Rio Hual- 
laga, O. Micuaris has discovered another race, pherenice subsp. nov., with less extensive orange colouring 
in the basal part of the under surface of the hindwings. The black spots of the green distal zone are more 
pronounced than in beatifica and olivencia, and Micuagt believes that higher up in the mountains we may find 
yet specimens forming a transition to beata. Mr. MicHarL wrote me about the habits, from Iquitos in 1910: 
On the 28th of September 1904, I found mor> than 30 Prepona sitting together near Inanjui, on the Upper Hual- 
Jaga. The day being very hot, the woods dry and nowheres a refreshment for thirsty butterflies, I found, at. an especially 
malodorous spot the said number of Prepona and in the midst of them in the greatest scuffle there sat an Agrias, allied 
to A. beatifica resp. beata. The Prepona were so madly eager after their meal that I could quite carclessly pick out with 
my fingers first the Agrias, then only I chose the best Prepona. 
beata Sgr. (114d) forms the southernmost known geographical extreme of the whole species and is certainly 
but a territorial form, although its author stood the most energetically for its specific rights. beata originates 
from the Chanchamayo in Peru and seems to be very rare, since but few specimens are known. On the upper 
surface the darkening of the blue area and of the green marginal band is very far advanced, and beneath the 
basal area is only yet covered with narrow red stripes. The scent-pencil is somewhat darker yellow than in 
A. narcissus. In the Coll. FRunstTorrerR there is a g without certain habitat according to which the figure 
was depicted. 
59. Genus: Coenophlebia Fidr. 
In spite of the great difference in the exterior, this genus is nearly allied to the palaearctic genus of 
Charaxes, being the most nearly allied to the following Polygrapha, which is likewise formed by but one species. 
The outward appearance is, as the figure shows, so peculiar that it is impossibly confounded. 
C. archidona Hew. (116 a), the only species, has hitherto been found in Colombia and Peru, but it 
presumably occurs also in Ecuador and is very rare. The 2 discovered by Mr. A. H. Fasst in East Colombia 
(Gin March at an altitude of 800 m) is somewhat larger than the g, above and beneath of paler colours and 
markings, and with a somewhat broader, light yellowish-brown costal-marginal border of the hindwings; all 
the dark markings are likewise somewhat lighter dark-brown, and the under surface with the silvery dots of 
a still more striking resemblance with a faded, bedewed leaf. — magnifica Fruhst. from Bolivia is considerably 
larger and beneath with more pronounced and darkened markings. 
60. Genus: Polygrapha Schaiz. 
As mentioned above, this genus is likewise nearly allied to Charawes which is also expressed already 
by the outward appearance. But the shape of the palps exhibits again an alliance with Anaea, whereby its 
affinity with Charaxes is manifested again. P. cyanea was also at first taken to be a species of Anaea. The 
difference in the structure of the veins, compared with that of the genus of Charaxes, is but very insignificant, 
so that Polygrapha, if its habitat were in the Old World, would probably not be separated from Charazes. The 
early stages are still unknown. 
P. cyanea S. and G. (116 a), the only species of this genus, has hitherto been found in Ecuador and 
Peru, and is still considered a great rarity. The magnificent blue, silk-glossy reflection on the upper surface 
can scarcely be depicted in the proper way. Very contrary to the upper surface is the plain, striated under 
surface which is to be considered as a protective attire. The Q is still unknown to us, and probably not known 
at all. 
61. Genus: Siderome Abn. 
This genus, to which but few species belong, is likewise characterized already by its outward appearance 
which is better distinguished by the figures than by words; it is impossible to confound it with other genera. 
The genus is distributed from Mexico to South Brazil and occurs also in the Antilles. The larva of nemesis) 
has a shape similar to that of the Prepona-larvae, the pupa being hardly different from that of Anaea *),. 
S. marthesia Cr. from Surinam and the Lower Amazon, is presumably the yellowish-brown form 
of confluens Sigr. (116 a), likewise from the Amazon. — nemesis ///. (— ide Hbn.) (116 b) is widely spread, for 
*) Clasping-organs of an extremely primitive, clumsy and ugiy shape, tegumen as if inilated, uncus bent like a 
finger, short. Valve basally very broad, somewhat tapering anteriorly. The distal margin running like in Zaretes, concave 
in the middle, valve long, with bristly hair, besides densely set at the end with bacilliform scales being indented at the tips, 
oedeagus broader than in any of the Nymphalidae examined so far, skinny. The segments of the coarse abdomen narrow, 
skinny at their joints, their upper surface covered with leaf-like scaly plates, being deeply indented at the top. The dif- 
ferences of the valve between Siderone ide from Brazil and Siderone mars from Peru are so insignificant that a specific 
connexion of the two forms is possible. (H. FRUHSTORFER.)
