C. hybr. harmuthi Kordesch (Vol. 2, p. 266, pi. 43 a), ah. unicolor Gunther is a parallel form to hyb r. unicolor, 
pernoldi ab unicolor Gunther. 
C. hybr. kindervateri Ivys. (Vol. 2, p. 265, pi. 43 a), ab. engadina Waldasch. is a dwarf form having engadina. 
only the size of porcellus. Central area of forewings yellowish white dusted with black. Oblique band blackish 
green with pale centre. Band of hindwings yellowish white. 
G. hybr. euphaes D.so. (Vol. 2, p. 265, pi. 43 a), ab. clara Aust. has yellowish grey-white ground colour- clara. 
ation of forewings. Costal zone pale olive. Middle streak fainter, Hindwings like euphorbiae. 
C. hybr. galidahli John (C. gallii Rott. A X C. euph. dahli Geyer ^). In comparison to hybr. galiphorbiae galidahli. 
Dso. the costal zone and oblique band of forewings are deeper and darker green. The narrow central area (which 
is scarcely wider than in gallii) is more whitish yellow dusted with black. Pale streaks along the veins are pre¬ 
sent but much reduced as compared with dahli. Anal spot on hindwings is smaller. Median band darker and red¬ 
der, inclining towards carmine red. Colouration of entire upperside brighter and markings more pronounced. 
Dorsal stripe of abdomen distinctly visible. Only E6 were bred. 
C. hybr. livopenor Muller (13 b) ( C. 1. livornica Esp. $ X P. elpenor elpenor L. §). Body almost like livopenor. 
elpenor, but the red is suppressed, so that it is green with the exception of red traces on thorax. Markings of 
wings more closely resemble livornica; costal zone of forewings is green, without interruption, the pale middle 
band is rose; outer margin violet grey-red. Hindwings have an olive-black submarginal band, which is out¬ 
wardly very wide and becomes fainter towards the inner margin. Underside grey-yellow. 
C. hybr. livorneuphorbiae Wolter (13 e) ( A. 1. livornica Esp. X C. euph. euphorbiae L. £) has generally u VO rneu- 
speaking more of euphorbiae than livornica characteristics. Base and tips of antennae white, middle area dark. phorbiae. 
Tegulae with narrow impure white inner edge. The hairs at edge of tergites from the 3rd tergite remind one 
of livornica. Brush at tip of anus with white central line. On forewings veins are marked with light colour. 
Oblique band similar to that of euphorbiae. Central area occasionally wider than in livornica, dusted with white 
anteriorly and posteriorly. Costal zone more like livornica. Markings of hindwings like euphorbiae, however, the 
outer marginal band narrower, but wider than in livornica. 
C. hybr. giintheri Niep. (13 d) ( C. 1. lineata F. E A C. euph. euphorbiae L. 5). Antennae grey-white. 
Head and tegulae with white edges, the white lineata markings on thorax almost extinct. Abdomen with 2 
dark dorsal lines. The black-white lateral marks on abdomen only to the 3rd segment and there only represented 
by a small black spot. Markings of forewings very pronounced with deep olive-green costal zone and oblique 
band and of very definite lineata character, only the veins are not quite so prominent. Hindwings remind one 
more of euphorbiae. 
C. hybr. gallivornrca Grossed; Kunz (G. gallii Rott. E X C. livornica Esp. §) is about midway between 
the parent forms. Antennae dark as in livornica. The white inner edge to tegulae of livornica is only indicated by 
a few whitish green scales. Abdomen with dorsal line as in gallii ; the short white subdorsal streaks of livornica 
only indicated on the 3rd but last segment. On forewings the costal area is wider than in gallii. Basal spot and 
outer costal spot remind one of livornica, the 1st and 2nd of gallii, between these white scales as in livornica. 
Central area somewhat narrower than in gallii. Oblique band like livornica, but in width more like gallii-, the 
narrowing of the band towards the hind margin midway between that of the parents, outer edge not so den¬ 
tate as in gallii. Veins with white scaling, but not so pronounced as in livornica. On hindwings the central band 
is a rich red, as in euphorbiae, but the costal margin is somewhat paler. Marginal area very narrow. 
C. hybr. fromkei Dso. (C. gallii Rott. E X hippophc.es Esp. £). Antennae olive green in the upper two fromkei. 
thirds. Very wide costal zone to forewings, the oblique band is more strongly marked towards the base than 
in hybr. euphaes, outwardly it is less dentate. Central area wider than in gallii with grey scales near the costal 
markings. Hindwings with rich red median band. 
C. hybr. pulcherrima Dso. (C. euphorbiae mauretanica Stgr. <$ x P. elpenor elpenor L. $) resembles the pulcher- 
reciprocal hybrid elpotanica Dso., but all colours are more vivid and more sharply sparated from one another. ™ 
On forewings the red patch before the olive green central area line is extended to the stigma. The white anal 
spot of hindwings is more faintly developed than in elpotanica. 
C. hybr. euphorbiaella John (13 c) (C. euph. euphorbiae L. x P. porcellus L. §) is a very nice but euphor- 
very variable hybrid, of which the description given here is based on an average specimen. Antennae white, biae 
somewhat longer and thicker than in porcellus. Head and thorax olive green, often interspersed with red. Te¬ 
gulae red anteriorly, with white outer edge, abdomen dorsally olive-green, ventrally and laterally unicolourous 
red. Ground colour of forewings red, sometimes tinged with dull yellowish. The black basal spot intermixed 
with white hairs. Oblique band of forewings pale olive yellowish, darker only at apex, hind margin and on 2nd 
radialis. Formation of oblique band as in euphorbiae, outwardly however very dentate and with dark edge both 
there and on inner border. The atavistic line generally present. Outer marginal area violet-red. The black basal 
spot of hindwings is wide and less incurved than in euphorbiae. Median band yellowish rose, partially with pale 
giintheri.
