most forms of cytheris found in the same localities. The forewings have in the outer half the ner- 
vules distinctly black also in the gg, whereas in cytheris this is only observed in the 992 and even 
there in a rather lesser degree. darwini 33 have the fringe whitish-yellow, the 99 yellowish-white, sharply 
checkered with black, the dark spots being united with the black spots at the extremities of the nervules 
into roundish patches not found in any form of cytheris. On the upper surface the hindwings, which are 
golden brown, have the outer half marked and coloured as on the forewings, having in the place of the 
postdiscal rows of black dots, which in valdiviana are always very distinct and in the southern forms of 
cytheris quite rudimentary, a black dentate transverse band which, however, is not always complete: between 
the costa and submedian vein, being in some specimens above the cell interrupted or aborted. On the 
under surface the forewings are of a duller colouring than above, the costal edge and apex yellowish, with 
the black markings almost obsolete, occasionally even completely wanting, only the 3 lower spots in the 
inner terminal row making an exception. From the costa near the end a short, narrow, brownish semi-band to 
the lower radial vein, enclosing two small, obsolete ocelli filled with yellowish; this band is outwardly indistinctly 
defined, proximally very sharply set off against the lighter area (in ¢3 yellowish, in 29 whitish), the light 
inner band corresponding to the whitish costal streak of cytheris. Fringe more distinctly and broadly mottled 
with black than in the largest specimens of cytheris. The termen which, especially in cytheris $3, 1s strongly 
indented, is in darwini feebly excurved, occasionally almost straight. On the under surface the hindwings, 
although resembling the paler 99 of cytheris in the markings, differ from them in colouring, being in ¢ 
very pale, in 2 darker fuscous. The nervules all more or less pale, almost whitish. The basal area as far 
as the apex of the cell marked with dentate spots, darker brown, edged with whitish; following these a 
broad, paler transverse band outwardly margined with darker beyond which a light area; hereafter 5 dark, 
light-centred ocelli, two in the upper, three in the lower portion, separated on the median vein by a whi- 
tish streak sharply angled towards the termen; beyond the ocelli a narrow, yellowish or whitish, dentate 
band, with the points very sharp, breaking through the dark terminal band joining the dark spots in the 
fringe. These terminal markings distinguish darwini from all other Argynnis, also from inca in which the ner- 
vules, although much clearer white, are on the dark terminal border not marked with sharp points. Antennae 
as in cytheris, with the shaft dark brownish, the club blackish above, edged with brown at the end, in ¢ pale 
grey beneath. Palpi of g¢ rufous, of 22 whitish ochreous, covered with long hair. Breast and legs as well as 
the lower side of the abdomen light coloured; the latter above in the gg covered with brown, in the 929° 
with grey hair. Puntas Arenas and East Fireland. 
A. modesta Blanch. (Type in the Museum of Natural History at Paris, locality not given); a very 
small form, taken in the mountains of southern Chile at elevations of from 7800—9800 ft., possibly identical 
with “A. dioides, of the terres magellaniques’? mentioned by Botspuvat in his description of A. dexamene, 
but about which I have not been able to find anything in the litterature. From cytheris modesta as well as 
the following forms may be easily distinguished by the shape of the wings; forewings elongate, oval, not in 
the least excavated; the hindwings almost wholly round, the costal edge distinctly convex, not concavely 
excavated. The colouring much lighter than in cytheris, pale reddish-yellow, the basal area faintly obscured 
on both wings. The black markings on the whole feeble, in the inner half greatly reduced, the postdiscal 
row in both wings composed of quite minute dots; only the median spots are relatively heavy and _ pro- 
minent, being almost united into a band, the submarginal spots roundish, isolated. The terminal lines mar- 
ked by distinct spots placed upon the ends of the nervules. Underneath both wings are a monotonous pale 
buff, marked as above, but even more faintly and monotonously, the forewings with a few almost obsolete 
rows of terminal dots, the hindwings without any trace of markings outside of four very indistmct rows 
of minute dots of pale olive colour, the nervules paler than the ground; fringe yellowish-white, sharply 
mottled with black on the veins, joining the terminal spots, very much as in darwini, from which, however, 
it is easy to distinguish by the markings of the under surface and by the absence of the black dentate line on 
the hindwings above. 
A. inca Sigr. (87 £) was discovered by GaReEpp in Bolivia and taken in larger numbers near Malaga, 
Huallatani, at an altitude of about 13000 ft. above the Sea. Although the upper surface shows the general 
markings of the group, resembling somewhat A. pales, the underside is quite different, also from A. sobrina 
Weym. which was taken by Dr. Stipe. at Sicasia in Bolivia at about the same altitude (only the 9 known); 
with this it shares the rounded shape of the hindwings and the peculiarity that the 99 are above chiefly 
pale red-brown, the gj always dark greyish-green, which is the very opposite of A. pales. Expanse: 1,0—1,3”. 
The peculiarly greenish-grey colouring of the upper surface of the 3 is much more decided than f. i. in A. pales 
2 fa. napaea or in A. paphia valesina Esp., only the macular row just preceding the termen is brownish. 
Both wings have the basal area slightly obscured by fuscous, with the black markings moderately heavy, 
varying but slightly in the size of the spots, and chiefly composed of isolated dots and streaks. The median 
band especially of the hindwings indicated by very fine striae. One 3 has the upper surface darker than the 
rest, heavily dusted with blackish; in several others it is faintly suffused with brownish. The 99 have the 
upper surface brown-yellow, in the basal area greenish; only quite rarely we find a faint greenish suffusion 
to beyond the middle of the wing. Both sexes have the fringe mottled with dark and pale, occasionally marked
