0. loewii Z. (Vol. 2, p. 77, pi. 14 c). — andresi form. nov. (6 e) denominates a form bred by the late andre.x. 
Adolf Andres from the desert of Mariout. It is peculiar by the paler grey-yellow markings in the with 
an extension of the white colour. This is especially prominent on hindwings. Also the are pale buff in con¬ 
trast to the $ of the name type which is black (6 d). 
0. niutabilis Trti. (6 d) is without a doubt closely related to loewii ; the light markings on head and mulabiiis. 
thorax are rose coloured as the base of wings, also abdomen is rose with a wide olive-brown dorsal stripe. 
The markings of forewings, as will be seen from the illustration are somewhat differently shaped and especially 
the markings near the margin are intersected by the pale nervules and the submedian pale longitudinal stripe 
is much narrower. Hindwings with rosy hue, otherwise similar to loewii. - mutata Trti. (6 d) shows paler mutata. 
markings which appear more brownish owing to interspersion of rose, only their fine edges remain darker. 
The $ has a vivid rose thorax and rudimentary wings, the rest of the body is impure rose. — The larva 
differs from that of loewii, it is jet-black even the warts not being paler but with bluish sheen: underside and 
prolegs white and rose; dorsal hairs brilliant rusty yellow. Bengasi (Cyrenaica) in November. A specimen from 
Egypt illustrated by Andres and Seitz in ,,Senckenbergiana“ 5, plate 1, fig. 4 as loewii corresponds exactly 
with mutata, which would therefore also occur in Egypt, unless possibly they are identical species. 
0. zoraida Grasl. (Vol. 2, p. 77, pi. 14 d, e). — lienricus Rbb. denominates specimens with 3 complete henricus. 
black transverse bands on forewings from lower median nervure to inner margin. Also on hindwings the dark 
outer marginal markings are confluent forming bands. — olaria Rbb. has on the other hand the black costal olaria. 
spots of forewing confluent forming a longitudinal streak, on costa extending to base. — blanca Rbb. denotes Mane,a. 
specimens with hindwings devoid of markings. 
0. nogelli Led. (Vol. 2, p. 77, pi. 44 d). This is deemed by Hampson to be a genuine species and I would nogelli. 
like to subscribe to this opinion as the insect makes a totally different impression to parasita (ibid.). — albo- albobnm- 
brtmnescens Strd. ( = ab. 1. Hmps.) is much paler, more of a whitish brown ground colouration, mixed with 
ochreous on thorax. Lydia. 
0. rothschildi A. B.-H. (6 e) has narrower wings than the very similar parasita, very rounded at inner rothschildi. 
margin and with bolder black markings; the black costal streak is only very rarely dissolved into separate spots, 
the heavy inner marginal streak extends right to the anal angle; in marginal area there are 3 distinct black 
spots; ground colour is dark grey with slight brownish tinge. Hindwings rather sparsely scaled with 3 roundish 
bold black marginal spots and a further one at apex. Bred $$ have rudimentary wings of 4—5 mm length with 
distinctly separate black spots which are sometimes edged with white. Abdomen with black edges to the seg¬ 
ments. It occurs at the end of March in Province Samara on the meadows around the Volga. The SS fly hi 
the sunshine. 
0. leprieuri Oberth. (Vol. 2, p. 77, pi. 14 d). — morisca Oberth. (6 e) has a black, not ochreous body and morisca. 
also the costa of the forewings which show much more black, has no trace of yellow. 
0. pudens Luc. (Vol. 2, p. 77, pi. 14 f, 16 a). denigrata Strd. (= ab. 1, Hmps.) shows the black mark- denigrata. 
ings on the wings considerably reduced. 
0. houlbeni Oberth. Body with brownish grey hairs; forewings fulvous, 2 transverse bands of black houlberti. 
dots in disc; outer marginal area to an extent of 2(/> —3 mm depth slightly darker brown, although in some 
specimens this is scarcely perceptible; the dot markings vary in strength. Hindwings somewhat paler with 
faintly rosy hue and black marginal band, fringes reddish. Size approximately as leprieuri. Ta-tsien-lu. 
0. latreillei Godt. (Vol. 2, p. 78, pi. 14 e). - ochraeea Th.-Mieg has forewings with ochreous bands. — ochracea. 
millierei Th.-Mieg with yellow hindwings is synonymous with aurantiaca Spul. (ibid.). — berthina Th.-Mieg berthina. 
has whitish forewings and white hindwings with faint rosy tinge. 
0. pretiosa Stgr. (Vol. 2, p. 78, pi. 41 e). As already mentioned in the main Volume, this should be classi¬ 
fied as a form of Micrarctia kindermanni. 
0. oberthueri Rothsch. seems somewhat isolated; Hampson places it next to Tancrea pardalina Piing. oberthucri. 
(Vol. 2, p. 75, pi. 14 b, 16 a). Head and thorax black-brown, admixed with greenish yellow or whitish. Under¬ 
side of thorax and tarsi yellow; abdomen black, underside and laterally with yellow hairs. Fore wings yellow, 
densely peppered with brown in basal area and brown veins; a diffuse brown oblique band before the centre, 
a black lunule at cell end and a yellow spot in front of same; beyond the centre a brown band and an un¬ 
dulate brown subterminal band, margin and fringes suffused with brown. Hindwings yellow, brown at base 
and inner margin with wide brown marginal band and yellow fringes. Wing expanse: 30 mm. Thibet (Kuku-Nor). 
0. joiceyi Talb. does not closely resemble any known species and is easily recognisable by the yellow joiceyi. 
ground colour and wide black margins to hindwings. Forewings smoky brown with 3 black confluent basal spots.
