generations of diniensis Bsd. of which he names the 1st cana. It is distinguishable by a greyer colour of the cana. 
black marks. — To the 2nd generation belong the varieties grandis Vrty. from Pian di Mugnone, Florence and 
magna Vrty. from Valdieri in the Maritime Alps. They are said to be larger than diniensis and differ only by 
their size. A name would seem superfluous. — obscurata Vrty. from the Isle of Elba, also of the 2nd generation obscurata. 
differs by its greater adumbration: two-thirds of the wing surface are dusted with grey towards the base and 
the whole appearance is duskier than in specimens of the 1st generation. — monovittata Vrty. from the coast monovittata. 
of Tuscany has a light band on the underside traversing the disc of the hindwings. — Stauder observed on 
Mount Faito and S. Angelo (Sorrent) a partly still larger race than major Grd., which he named stabiarum. It stabiarum. 
flies at an altitude of 700 to 1400 m. The apical mark is round and greyish, black in the middle and double 
as big as in the name type form. Costa and base of wings dusted with black. The $ has in place of the apical 
mark only the relative veins powdered with black. — Stauder names as individual variations still (J-ab. 
apicedivisa. The apical mark is divided by white veins in such a way that two separate spots are created apicedivisa. 
and ab. brunneomaculata, 36 with clearly pale brown apical mark. — ab. simbruina Dannehl flies in the South brunneoma- 
Carpathians, Mount Sibillini and Campagna. It closely resembles stabiarum. , is fairly large and a rich white. . , cu } ata - 
r x . ° simbruina. 
The 36 with sharply outlined round apical mark, the $$ with fainter grey. Underside of the hindwings pale 
yellow. — In Corsica a small race still occurs with yellow toned wings on the upperside of both sexes: 
Corsica Vrty. In the spring generation the underside also shows a brownish powdering without any admixture Corsica. 
of green. — ab. andromorphica Vrty. are $$ of the summer generation from Corsica with the apical mark of andromor- 
the 36 although certainly somewhat smaller. — A separate race deserticola Vrty. also flies around Beirut in ^ phica. 
Syria. It is only very small and daintily built with narrow wings. The 3 has a very reduced, diffuse grey apical 
mark, which does not touch the margin of the wings and lies isolated like an island, syriaca Culot is identical 
with it. — ab. pseudodiniensis Pfeiffer are richly white 36 from the inner Anatolian chalk mountains with the pseudodi- 
apical mark powdered over with white and with two striking deep black oblique bars and with a rectangular mensxs. 
shape inwards. The underside is yellow green, forewings with reduced sharply outlined apical mark. In the 
$ the underside is also green and in the apex of the upperside of the forewings only a few grey longitudinal 
streaks along the veins indicate the apical mark. — ab. lathyrides Vrty. is a spring form from Amur and lathyrides. 
Transbaikalia. It is only small and the underside reminds one of vibilia Jans, by its yellowish tone and the 
brownish markings. — majorides Vrty. flies in S. Russia, being midway between sinapis and major Grd., major ides. 
specimens being all of goodly size, extensively and diffusedly marked on the underside. Apical mark is grey 
as in diniensis. — Dwarf forms are minor Blachier (= minor Ksienschopolski, minor Derenne). — In a lengthy, minor. 
very interesting treatise Lorcovic claims the right of a species for major Grund as a summer form and 
croatica Grd. as the relative spring form. However his deductions are by no means convincing, all the more 
as he must admit that there is no difference in regard to the genital organs as compared with sinapis. 
L. amurensis Men. (Vol. 1, plate 27 g). The newly established forms of Verity require further amurensis. 
justification before acceptance, as the differences appear very trivial and unimportant. The 1st generation 
of morsei Pent, has been named morseides Vrty. the only difference being its smaller size. — vibilioides Vrty. morseides. 
is also a spring form, the specimens having a more elongated and pointed wing contour than morseides. From ^dioides. 
the Amur. — emisinapis Vrty. from Irkutsk is also similar to morseides and reminds one slightly of sinapis. — emisinapis. 
A separate race flies in Japan, japonica Vrty. It is considerably larger in size and has more elongated wings, japonica. 
The apical mark is also striking by its more considerable size and deeper black. — The species described as a 
separate species inornata from Hokkaido in Japan is to be deemed a subspecies to amurensis. The wings are inomata. 
somewhat wider than in the name type form and show a rounded apex. The apical mark is absent from the 
upperside of the forewings. The underside is silvery white and only powdered with black along the costa at 
the base of the wings. 
L. duponcheli Stgr. (Vol. 1, plate 27 g). The older name aestivalis Bellier should take the place of duponcheli. 
aestiva Stgr. — Verity mentions a new race from Syria ab. xanthocliroa for the spring generation. The upper- 
side of the wings is a beautiful yellowish green. The underside of the hindwings in both sexes is a nice yellow. ' chroa. 
L. gigantea Leech (Vol. 1, plate 27 g). 0. Bang-Haas describes a new subspecies from Kansu in the gigantea. 
Tsinling Mountains: tsinlingi. It is easily recognisable by its black isolated apical mark. The black marginal tsinlingi. 
band of the underside of the hindwings reflects through distinctly on the upperside. 
Addendum. 
C. Iadakensis Fldr. The new subsp. seitzi of this insect flies in West Tibet, Chumurti, Shilong Pass at ladakensis. 
an altitude of 4800 m, which is characterised by its smaller shape and the reduction of all dark markings. The se d~' 1 - 
$$ especially show the marginal and submarginal bands pale black interspersed with many yellow scales. The 
black can quite disappear on the hindwings. The ground colour is not so bright as in the name type form. — 
flava Ril. must be mentioned here as an aberration. flava.
