0. herrichi Stgr. (16 a) is a transition from baetica to the following group. Size and shape o{ herrichi. 

 baeiica, but the dark markings in the basal half of the wing strongly reduced, so that the hindwing is 

 quite white with the exception of the marginal band. From the Taurus. 



0. loewii Z. {= clathrata Led.) (14 c). Forewing of (^ with similar markings to baetica, but the loewii. 

 white bands broader and the spots before them not black but olive-green. Hindwing dirty white with 

 olive spots. Wings of the $ reduced to very small remnants. Asia Minor, Syria and Egypt, as well as 

 on Rhodus. — The Armenian form, armena .S'/r/r. (14 c), is darker, the olive spots on the forewing only armena. 

 leaving light lines, and merging together on the hindwing to form bands. — On the contrary, pallidior pallidior. 

 Christ. (14 c), the form from Turkestan, is considerably lighter in colour in consequence of the broadening 

 of the light bands on the forewing and the separation of the dark bands on the hindwing into rows of 

 spots. — Larva black-grey, with dark marmoration and yellowish white dorsal line broadly interrupted 

 from the third segment; laterally rows of yellow-grey obhque spots, which are sometimes indistinct. Hairs 

 dorsally reddish brown, laterally wliitish. In April on low-growing plants. Pupa reddish brown, in a 

 cocoon of earth in the ground near the surface. The moth is common and flies in September and 

 October. According to Christopii it is difficult to rear. 



0. zoraida Grasl. (14 d, e). As large as, but more brightly coloured than, the preceding; thorax zoraida. 

 and abdomen with dense long hair. Wings dull light pink, forewing with large, black costal spots con- 

 tinued as flexuose bands, which reach to the median vein and its branches; hindwing sparsely spotted. 

 The wings of the 9 are only developed to half the normal size. In Spain. — Larva velvety black, said 

 to resemble that of A. testudinaria. In June and July, on Plantago, Salvia, Taraxacum, and other low- 

 growing plants, in daytime beneath leaves. Pupa reddish brown. Moth emerging the following May. 



0. hemigena Grasl. (14 d). Smaller and darker than the preceding, standing between zoraida and hemigena. 

 leprieuri. Spots of the forewing essentially smaller, only a few small spots on the hindwing. ? very like 

 that of leprieuri, the spots only sharply defined and complete at the costa. From the Pyienees. — 

 Larva lead-grey, with broad whitish grey dorsal stripe and black warts bearing dark hairs. In July and 

 August, on low-growing plants. Pupa reddish brown. The moth in May. — hemigena and zoraida are 

 doubtless representative species, but cannot be regarded as forms of one species, if the widely differing 

 descriptions of the larvae are correct. 



0. parasita ffl)«. (14 c). The species which is found furthest north. Dark sooty reddish brown, the fore- parosita. 

 wing in the o with black basal rays and small angulate spots, hindwing with dark square spots. $ with 

 the wings developed to '/2 or ^/4, and with dark spots throughout the forewing and at the margin of the 

 hindwing. Hungary and the Danubian countries. South Switzerland and Southern France. — At the 

 Black Sea the form intermedia Stgr. occurs, which has the basal streaks shorter and the spots smaller, intermedia. 

 and the hindwing uniformly grey. — nogelli Led. (14 d), from Lydia, has the forewing entirely without nogelli. 

 spots, or only slight traces of them. — Larva yellow or brown, with yellow brown hairs, three dark 

 dorsal lines, between which there are dark dots. Stigmata white. In May and June, on low-growing 

 plants, Hke gentian, nettles, also on grass; pupa reddish brown in a grey cocoon. Moth in the early spring. 



0. leprieuri Oberth. (14 d). Thorax dark reddish brown, densely covered with yellow-brown hairs; leprieuri. 

 abdomen dull reddish yellow, with dark dorsal line. Sometimes the ^yellow hairs give the whole body a 

 golden yellow appearance. Wings sooty reddish brown, rather transparent. When held before a dark 

 background the forewing has a yellow-red costal area in which there are 4 or 5 small costal spots. The ? 

 has very short wing-remnants, which are hidden in the woolly covering of the thorax. The costal spots 

 of the ^ are sometimes scarcely recognisable. In North Algeria. — Larva dark grey-brown, with red hairs 

 in the centre and blackish ones at both ends, so that it superficially resembles the larva of plantaginis. 

 It feeds until the beginning of June on low-growing plants, especially on borage, beneath the leaves of 

 which it rests in daytime, and pupates in a white ovate cocoon, the pupa being short, red-brown, with 

 dark markings. The moth does not appear until the following March or April. I have found that 

 the wings of the (J also develop when the insect remains on the ground, the wings being kept erect. 

 Locally very common. 



0. pudens Luc. (14 f ^, 16 a (J). Greyish red, thorax and forewing more or less tinged with pwdcns. 

 yellowish red. A shadowy line composed of dark spots on the back of the abdomen. Forewing with an 

 abundance of small blackish spots, arranged in three or four transverse lines. Hindwing also spotted with 

 blackish, especially in the apical area, with dark discal streak. $ almost exactly like that of leprieuri, 

 blackish, woolly. Mauretania and the opposite Andalusia. — Larva dark brown, with blackish brown head 

 thinly marked with white, and black-brown nuchal shield divided by a pale line. Hair black at both ends 

 and reddish in the centre. Dorsal line thin, white. 



0. latreillei Godt. (14 e). Body shaggy, black, as is also the forewing, the latter traversed by white lalreillei. 

 bands differing much in size. Hindwing dark rose-red, with black marginal band and central spot. ab. aurantiaca a^irantiaca.
