The formation of the bands on upperside is subject to considerable variation on both wings. The following 
6 forms are named: luteofasciata, bands with orange-yellow with reddish tone, brightly coloured and cont¬ 
rasting sharply from ground colour. — rufofasciata have red-brown, duller bands that do not stand out so prom¬ 
inently from ground colour. Both forms occur in d and $. - purpureofasciata appear only to occur in d, bands 
are dull purple and do not contrast very much. — ab. albofasciata Osth. with dull grey spots instead of the 
red band of spots. - progressiva denotes specimens now and then occurring among subsp. mantoides Esp. 
(p. 134), which exceptionally at least on ujrperside bear the characteristics of a more richly marked sub¬ 
species. — In contrast hereto regressiva denotes specimens of name type form and mantoides Esp. which 
exceptionally and at least on upperside show the characteristics of a more poorly marked race. — Band on 
underside of forewings varies as follows: subtus-luteofasciata, band on underside of forewings light, predomin¬ 
antly yellow, not only towards costa; on the other hand subtus-rufofasciata is darker on underside with 
mainly reddish tone. Both forms occur among E and $. 
Also hindwing bands vary and caused Muller to give the following denominations: subtus-brunnea 
with outer band on underside of hindwings unicoloured brown, without reddish tone, but standing out clearly 
from ground colour. This form has only been observed in E- — - subtus-ferruginea occurs in both sexes, rarely 
however in $$, in certain local forms however commonly. The fuscous to fulvous unicolourecl outer band 
characterises the form. — subtus-bicolor are EE with fuscous to fulvous outer band, but all or a few of the 
band of spots are yellow. This two-fold colour is very striking. — subtus-aurantiaca has a bright yellow 
outer band without a reddish tone, this variety occurs regularly in the E> but only very occasionally in §. 
- subtus-ochrea has a buff or pale ochreous band in both sexes. It is the usual form of $$. —- subtus- 
maccabaeus are $$ with rusty red coloured outer band on underside of hindwings. — subtus-lutescens 
occurs in both sexes, outer band is very pale, creamy yellow. This form is often erroneously classified as 
ab. bubastis Meissn. — d'-ab. subtus-fasciata has outer band on underside of hindwings wider and more or 
less contiguous, it stretches from costa to close to hindmargin. —- subtus-semifasciata denotes forms having 
the subtus-fasciata band wide, but limited only to the costal half of wings or such with band of only half 
normal width, which however is coherent and extends from costa to hindmargin. 
subtus-basimacula 
are Ac? with basal spots on underside of hindwings. — $-ab. subtus-privata have no basal band on und¬ 
erside of hindwings. This denomination only refers to forms, where it is not a characteristic of the race to 
be without basal bands. 
macularis. The marking of the bands is subject to the following variations: macularis has band of forewings 
on upperside dissolved into generally 6 well developed spots which fill out or almost so the interstices 
reduda. between the veins. Towards hindmargin these spots often decrease in size. — reducta has band of forewings 
redudis- reduced to 3 or 4 narrow streak-like spots, so that one can scarcely call it a band. reductissima indicates 
sima. a further reduction of the band. Here forewings show a more or less extensive circular halo around the 
2 apical eyespots, as the only indication of a band and in extreme cases even this is absent. — ab. 
diffusa, diffusa denotes specimens with less sharply outlined band which merges in ground colour. — ab. postniacu- 
post- Jaris has on upperside of hindwings several, most commonly 3 medium-sized spots forming a band, whilst 
macularis ( A < ~ > ** 1 t 0 
pluri- plurimacula has generally 4 or more such spots. — postreducta in contrast hereto, is not rare. Spots of 
macula, hindwing band are reduced in size and number and can even be completely absent. This reduction of 
postreducta. hiivclwing markings is quite independant of the markings of forewings, which may be rich, whilst hind- 
subtus- wings are poor. — subtus-benesignata are specimens in which the pale band on underside of forewings 
benesignata. extends uninterruptedly in medium width from hindmargin to cellule 5 or 6 and often in cellules 4 
subtus- and 5 is elongated towards the base. Band is sharply outlined on both sides. — subtus-minussignata in 
minus- contrast hereto, has band of forewings reduced on underside, i. e. it is either considerably more narrow, 
stgna a. g j 10I q enec p or dissolved into single spots, which may also sometimes be reduced in number. Occasionally 
the spots are as faintly marked as in subtus-obsoleta, so that they almost entirely merge in ground 
subtus- colour. subtus-completa occurs in both sexes and is characterised thereby that in E the outer band 
completa. 0 n underside of hindwings generally consists of well separated, medium large single spots, whilst in the 
$ of 7 or 8 generally coherent large spots. The lower spots are somewhat smaller in both sexes. 
subtus- The $$ have a well developed basal band. — subtus-reducta are EE and $$ in which the outer 
reduda. band on underside of hindwings is reduced, either the number of the spots of the band is considerably
