wings attains but a moderate extent. The 9 resembles certain jg of A. amydon to such an extent that I found 
it arranged among such in the Coll. Gopman. The @ stands between zenodorus Hew. and frontina Fruhst., and 
it resembles frontina in the colour and the course of the discal band of the forewings, though it has pale yellow 
spots before the apex, like zenodorus. The under surface of the forewings is lighter than that of amydon with 
a broader yellow apical band. In the basal area we distinctly notice a yellow tinge near the distal margin, being 
absent in amydon. Entirely different from amydon, however, is the under surface of the hindwings which show 
the greatest likeness with A. boliviensis Fruhst. described above. The bands in the cell are greatly reduced, 
so that the yellow ground-colour is everywhere predominant, and the blue-pupilled submarginal spots, being 
fused into a broad band in amydon, stand dissolved forming a macular band interrupted by yellow. — ozora 
subsp. nov. is the race from Peru presented by us as amydon (115d). The forewings somewhat resemble those 
of amydonius Stgr. (115 d), but the red basal area of the forewings is reduced. The subapical spots at the apex 
of the forewing are in nature not so prominent as in the figure. The hindwings bear a discal, not subanal 
spot as in eleonora and boliviensis. The under surface forms a transition from that of A. amydonius to 
A. boliviensis. The forewings are more richly striped in yellow than in the gg of amydonius, and on the 
hindwings the eyespot-bands are more broadly spread and their components confluent in nature, not iso- 
lated as in our figure. The name-type originates from Charapajos (Peru) and was collected in 1889 by 
De Maruan for Co. OBERTHUR. Similar specimens are in the Coll. SrauprinceR from Yurimaguas (Peru), 
besides also the fa. larseni Fass] as a rare aberration, and furthermore specimens approximating the 9 of 
zenodorus by a remarkably large magnificent spot of the upper surface of the hindwings. They belong 
to the fa. athenais Frukst. — In Bolivia the collective species is represented by a considerably modified 
territorial form, boliviensis Pruhst. (114 b). It agrees with eleonora by the anally dislocated discal spot of 
the hindwings, which characteristic mark may be more noteworthy than it was considered hitherto. If by 
the discovery of the early stages or by morphological proofs the forms with subanal blue should be entitled 
to be considered as a proper species, they would have to be placed by the type of A. eleonora, the modified 
under surface of which and its occurrence from Ecuador to Bolivia sets one thinking. According to Fasst, 
amydon occurs in Bolivia especially in the yellow form of boliviensis Fruhst. The 33 vary in the shape of the 
yellow spot of the forewings, but also the blue anal spot of the hindwing grows very dark violet and reduced 
in some specimens, and Fasst does not doubt that we may also capture A. boliviensis with quite black hind- 
wings, analogous to those of amydon of which Fass found his form in East Colombia without any blue at 
all, describing it as fa. larseni. The under surface of boliviensis is likewise rather variable, especially the 
black band enclosing the row of eyespots may be increased or reduced. Another interesting fact is that nearly 
all the boliviensis taken by Fassut on the Rio Songo before the rainy period (in October until December 1912) 
belonged to a small pygmean or famished form, probably created by the extremely dry winter in Bolivia (the 
dry period is May to September) of the year 1912. A ¢ of this collection is not larger than a respectable 
Catagramma aegina from the same habitat, and the sole 9 figured 114 b (first figure) is by more than a third 
smaller than the two other 9° captured after the rainy period. All the three correspond with the sole 9 of 
boliviensis known already before, in the resemblance with the ¢¢, thus being also decorated with large 
blue anal spots of the hindwings, being therefore quite contrary to those of genuine amydon-2@ all of 
which exhibit not a trace of blue. — amydonides Fruhst. (= songoénsis Fruhst. being regarded but as a 
rare red aberration of boliviensis, lay before Fassu only in 5 specimens so far; it is very rare among the 
yellow forms and pretty well distinguishable from the amydon-forms of other localities by the red band 
being peculiar on the under surface, since its colour is exactly the intermediary between the red of genuine 
amydon and the yellow of boliviensis. Perhaps we may succeed yet in capturing also the 9 of it whereby its 
alliance with A. boliviensis could be better cleared up. In judging especially the forms with a reduced 
blue, the position of this magnificent spot of the hindwings ought to be above all decisive for the assignment 
of the animal, for by this blue discal or anal spot of the hindwing certain forms are much more sharply 
separated from each other than by the most variable bands of the forewings or the extremely detailed helical 
markings of the under surface, by which for instance some butterflies being very different above (such as 
amydon, amydonius and ferdinand?), are not at all to be separated from each other on the under surface. ,,Who- 
soever, like myself, had the chance to capture personally, for instance, Agrias amydon in greater numbers and 
at different places, will have to own that the reduced blue in the poorly-coloured varieties (muzoénsis and transi- 
tions to larseni), which finally consists only yet of a narrow longitudinal streak in the anal angle and _ parallel 
to the anal margin, presupposes an entirely different development of the distribution of colours, as the blue 
spot of Agrias lugens receding always entirely centrally (discally), however much some sardanapalus-specimens 
may make the impression that the blue is chiefly distributed towards the anal.‘ (Fassu). — ferdinandi Pruhst. 
(115 c) deviates from all the noted amydon-races by the absence of every discal spotting of the upper surface 
of the hindwings, and is very near to being considered a proper species. Beneath it is characterized by the black 
marking in the cell of the hindwings not forming a fork but a more plain, peculiar figure comparable to the 
swollen ring of an earth-worm. The row of eye-spots consists of a rather loose joining. The ground-colour 
of all the wings is deep velvety black. j-upper surface: base of the forewings with a broad, intensely carmine
