428 ARGYNNIS. By Dr. Th. Lehmank. 



most forms of cytheris found in the same localities. The forewings have in the outer half the ner- 

 vules distmctly black also hi the (JcJ, whereas in cytheris this is only observed m the $$ and even 

 there in a rather lesser degree, darwini JcJ have the fringe whitish-yellow, the $$ yello\^'ish-\\■hite, sharply 

 checkered with black, the dark spots being united «ith the black spots at the extremities of the nervules 

 into roundish patches not found in any form of cytheris. On the up2>er 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 vakliviana 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 forewmgs 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 sjjots in the 

 inner termmal row makmg 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 cJ^J yellowish, in $$ whitish), the light 

 inner band corresponding to the whitish costal streak of cytheris. Fringe more distinctly and broadly mottled 

 with black than hi the largest specimens of cytheris. The termen which, especially in cytheris (^(^, is strongly 

 indented, is in darwini feebly excurved, occasionally almost straight. On the under surface the hindwhigs, 

 although resemblhig the paler $$ of cytheris m the markings, differ from them in colouring, being m (J 

 very pale, in $ 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 m 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 browAish, the club blackish above, edged with brown at the end, in ^ pale 

 grey beneath. Palpi of i^,-^ rufous, of $$ 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 3*o covered with brown, in the $$ 

 with grey hair. Puntas Arenas and East Fireland. 

 modesta. 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 Boisduval in his description of .4. dexaniene, 

 but about which I have not been able to find anything in the litterature. From cytheris mode.sta as well as 

 the following forms may be easily distmguished 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 niuch lighter than in cytheris, pale reddish-yellow, the basal area faintly obscured 

 on both wings. The black markmgs on the whole feeble, in the inner hah 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 indistinct 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. 

 inca. A. inca Stgr. (87 f) was discovered by Garlepp in Bolivia and taken in larger numbers near Malaga, 



Huallatani, at an altitude of about 13 000 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 .4. sohrina 

 Weym. which was taken by Dr. STiJBEL at Sicasia in Bolivia at about the same altitude (only the $ known) ; 

 with this it shares the rounded shape of the hindwings and the peculiarity that the $9 ^i'© above chiefly 

 pale red-brown, the (^,^ 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 q is much more decided than f. i. hi A. pales 

 9 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 <^ has the upper surface darker than the 

 rest, heavily dusted with blackish; in several others it is faintly suffused with browmish. 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 frhige mottled with dark and pale, occasionally marked
