dark, only interruptedly pale in its narrow central stripe. A $ captured near Herne Bay, Kent. ab. illineata illineafa. 
Prout (Vol. 4, p. 248). To this is to be sunk, as Osthelder indicates, ab. uniform,is Kautz, a 9 from Attersee, 
with even the principal lines no longer white. — ab. suhillineata Strand is the transition in which the principal subillineata. 
lines (postmedian and on forewing subbasal and antemedian) remain white but the other markings (except a 
slight brownish shade at outer edge of median area) are obsolete. A small $ from Marburg. ab. unidentaroides unidentaroi- 
Strand. Chiefly distinguished by the reduction of the subordinate teeth of the postmedian, only a strong, scarcely 
bifid, central prong remaining. Median area somewhat darkened. Marburg (type) and Stuttgart. - ab. marga- margarUata. 
ritata Kautz. Central part of median area broken, by partial confluence of its boundary-lines, into spots which 
are likened to a chain of pearls; some may be punctiform or obsolete, according to the strength of the anasto¬ 
moses. Described from Austria. — ab. prillingeri Kautz , an erratic 9 from Purkersdorf, lias the white post- prillingeri. 
median of the forewing almost without teeth, with sharp black-brown shade proximally, the 2 lines which bound 
the central stripe of the median area widely sundered (3 mm apart), the boundary-lines of that area near them, 
the subbasal and subterminal wanting; distal are of both wings unicolorous; hindwing with 4 distinct lines. 
The cell-dot of the forewing is merged in the 2nd antemedian line. - ab. cuneata Osthelder has the subterminal cuneata. 
accompanied proximally by strong black-brown wedge-marks. Innsbruck. — testaceolata Stgr. (Vol. 4, pi. 10 i). testaceolata. 
much better differentiated from b. bilineata in the $ than in the <$, is also the prevailing form on Corsica, accom¬ 
panied by its ab. infuseata Gmpbg. (sens. lat.). Various individual aberrations from that island have also been 
named by Kautz; this is the source of the 7 which follow here. Bubacek adds that bistrigata Tr. does not occur 
on Corsica but only on Sardinia. — ab. insignata Kautz. Unmarked with the exception of the white lines, 3 on insignata. 
the forewing, 1 on the hindwing; even the subterminal is only weakly white; the Corsican representative (almost 
synonym) of ab. subillineata. — ab. brunneata Kautz. Forewing brown, hindwing yellow-brown; the markings brunneata. 
normal. ab. coffeata Kautz shows a further progression in the brown colouring, both wings being chocolate- coffeata. 
brown; markings normal. — ab. anaemica Kautz. Strikingly pale, the forewing light grey-yellow, the hindwing anaemica. 
pale yellow; markings normal. It is said to occur both in the name-typical form and in testaceolata and also to 
produce ab. infuscata (sens. lat.). — ab. phaeotaeniata Kautz. Ground-colour of both wings gold-yellow, the phaeotaenia- 
median area of the forewing (between the 2nd and 3rd white lines) filled up with deep brown. This and the 
following occur in similar forms in other localities. — ab. bubaceki Kautz. Striking on account of the develop- bubaceki. 
ment of an uninterrupted, pure white transverse stripe, broader or narrower, in the median area of the forewing. 
This aberration also can be combined with the infuscata development and is frequent in subspecies atlantica , 
etc. — ab. stygiata Kautz. Forewing much more strongly darkened than in inf uscata. especially the distal part stygiata. 
of the wing. — balearica Schawerda has both wings white banded, the fore wing deep yellow, the hindwing of balearica. 
a grand red-yellow. Founded on a good series of both sexes from Mallorca. — numidica Bothsch. (15 d), proposed numidica. 
to cover the North African forms, from the extreme west of Algeria to Cyrenaica, is very variable but the So 
show on the whole more contrast between the greenish or greyish yelloAv of the forewing and the bright orange 
of the hindwing anteriorly and the 9$ are in general more deeply coloured than in testaceolata-. markings of hind¬ 
wing generally obsolescent anteriorly; dark borders of underside generally strong. dumetata Schrank (15 c) dumetata. 
has assumed a further importance since the publication of Vol. 4, owing to the fact that it seems to be, as Heyde- 
mann expresses it, “ab. (et subsp. partim)”. He finds this leather-yellow form (originally described from Ba¬ 
varia) to be the prevailing 9~f° rm on sand-dunes of the North Sea Islands, occurring together with frequent 
examples of infuscata Gmpbg. As the result of an analysis of an Ainrurn series, he records that the q o are half- 
and-half (typical and a transitional form which he classifies as the $ to dumetata). I suspect that my record of 
testaceolata from the Scottish sandhills may have had reference rather to dumetata. 
C. bistrigata Tr. (Vol. 4, pi. 10 i) ab. beata Bytinski-Salz. Median area of forewing broadly white, on beat a. 
a dark ground-colour. — ab. paulae Bystinski-Salz. Median area broadly black, on a relatively light ground- paulae. 
colour. — ab. selmae Bytinski-Salz. Median area whitish for a normal breadth, bounded by dark blackish selmae. 
dentate bands, which stand out distinctly from the dark-brown ground-colour. 
C. consentaria Frr. (Vol. 4, pi. 13 b as russaria). I know of no addition to the range of this species, consentaria. 
Sterneck, indeed, doubtfully recorded it from Pekin, but in a later communication, reporting a Corean spe¬ 
cimen of his Pekin species, he definitely asserted that it was not consentaria. which in the mean time he had 
learned to know. Probably it was a new species, but I have no further elucidation of it. 
C. purpurariarum Rbl. is said to belong to the bilineata group and is compared by its author with purpuraria- 
Packard’s figure of albosignata and Holland’s of “ sitellata ” (i. e. stellata Guen.). It is thus certainly a represen¬ 
tative of the last-named and natalata Walk. (cf. Vol. 16, p. 86); a passing examination of the and 9 when I 
was in Vienna confirmed this relationship and I noted that they would be rather small for natalata and with an 
ochreous cast, especially between the postmedian and the subterminal. Perhaps a distinguishable island form.
