5. Family: Nymphalidae. 
The Nymphalidae are about the most handsome and in part the commonest of all day butterflies in our 
latitude. With the exception of a few new discoveries in palaearctic Asia, there have been practically no addi¬ 
tions of justified new denominations. However very numerous names have been applied in the last 2 decades 
to specimens bred under artifical conditions and to individual varieties. Even if a definite locality is stated, 
it has not its customary value, as the variation may be due to chance and there is nothing to prevent a 
recurrence of a similar aberration occasionally in an entirely different district.

in great number especially by Cabeau and as a matter of fact all his new forms have almost only been captured 
in Virton and the Foret de Bure in Belgium. Only when other localities come into question are they mentioned, 
otherwise it is always one of the aforementioned. It is not difficult to form an opinion as to the value and 
purpose of these denominations. <$ ab. romaniszyni Schille has all markings like the type but the sheen is a romanis- 
beautiful violet blue simultaneously all over the butterfly in all positions. The extension of the blue colouration z1jni 
also spreads on to the hindwings. The dull, black-brown ground colour is only then visible if one places the 
butterfly at a particularly oblique angle and even then the blue always predominates. — $ ab. viridans viridans. 
Cabeau has a very wide margin on upperside of wings, shining greenish. — The ab. thaumantias Cab. only thaumcm- 
differs from typical iris by the ground colour of the wings, this is shining yellow-orange-red marbled with 
brown. — Also iriella Cab. only differs therein, that it is about 1 / i rd smaller than normal and the white iriella. 
traverse band on hindwings is considerably reduced. — <$ ab. deschangei Cab. has 9 more or less well marked deschangei. 
white spots oh forewings that are smaller than in typical specimens and not confluent. The white traverse 
bands of hindwings are complete, but straighter than in the type form. The very pale brown submarginal band 
usually shows no trace of grey internerval spots. Between the two bands of the hindwings a few faint yellowish 
scales are strewn in the 3 upper cellules. — $ ab. stlctica Cab. differs from typical iris rfc? by paler black- stidica. 
brown ground colour to wings; the 8 to 9 white spots of forewings are only small and are isolated, as if thrown 
on. The white traverse band of hindwings is striking being intersected by the black veins and forming 5 spots. 
The markings of underside appear somewhat reduced. — ab. bureana Cab. has black-brown ground colour bureana. 
with only 5 or 6 very small whitish grey spots on forewings, of which those at margin of wings are somewhat 
larger and purer white. The hindwing band as in stictica but more reduced. — Smokey brown ground colour 
characterises ab. tetrica Cab. as well as the reduced number of small grey spots, of which 2 are in the apical teirica. 
and one in the costal areas of wing. The band of hindwings shows the uppermost spot almost merged in the 
ground colour, the next two lower ones are grey, whilst only the 3 lowest ones have remained white. Anal 
eyespot is well developed. Underside is paler than in name type; the light markings are more or less reduced. 
<$ ab. vidua Cab. shows a much darker, black-brown ground colour than previous aberration; the mainly greyish vidua. 
spots of fore wings number 3 to 6. Only the 3 lowest spots of the white band of the hindwings are whitish 
and at the same time very reduced in size, the upper ones are merged in the ground colour. Anal eyespot is
