of different species. Firstly hispida Hbn.-G. is to be removed from the synonyms; oditis is a genuine species; 
it is smaller than hispida , with brown forewings, veins, transverse lines and stigmata yellowish white to 
ochreous yellow; hindwings grey-white, dusky at margin, somewhat darker in discal lunule and postmedian 
band indicated. As the illustration does not represent the type, we are giving a correct illustration here (16k). 
Nothing definite can yet be said as to its distribution, owing to the confusion prevailing regarding all the 
forms of these allied species. It is certain however that oditis is the only form occurring in England. The 
form — argentea Tutt is deeper brown, veins and transverse lines pure white, only stigmata somewhat more arycnlm. 
yellowish, the outer transverse line inclined to be grey, the wide outer line, that is parallel to margin, is 
again pure white. — pallida Tutt also belongs to oditis. It is pale grey, somewhat dusted with brown, costal pallida. 
area yellowish white. Hindwings white with scarcely any darkening at margin. - obsoleta Tutt has darker obsohla. 
grey-brown forewings, the markings are reduced and faint. All these forms are from England. — intermedia intermedia. 
Tutt (16 k) is the continental form from France, Spain, Italy etc. It is distinguishable by its less bluish brown 
ground colour. It is usually larger with wider wings and generally less contrasting markings. The orbicular 
stigma however stands out prominently pale. 
L. hispida Hbn.-G. (16 k) is a different species. It is larger, wings are wider, orbicular stigma more hispida. 
prominently yellow-red. The pale veins are narrower. The subterminal area is scarcely paler than marginal 
area, whilst in oditis it is distinctly paler. The white submarginal line often gives the impression of being 
undulate, whilst in oditis it is always quite straight. Hindwings usually purer white, in J with more distinct 
subterminal band, in $ a postmedian line is generally more distinct. — purpurascens Trti. has a deeper black- par- 
brown ground colour, faintly suffused with rose, veins and transverse lines scarcely prominent, stigmata with vurasccns. 
delicate white surrounds. — rufescens Trti. on the other hand is fuscous, no rosy hue, stigmata and subterminal rufescens. 
area a rusty brown, veins and transverse lines reddish brown and not white, only the subterminal line remains 
white. To this must be added: — hispanica Warr. placed in the Main Volume to oditis, it is a somewhat smaller hispanica. 
rather paler brown form with all lines, veins and stigmata ochreous yellow, instead of white. — blanca Ribbe blanca. 
is much paler in general colouration, the stigmata and lines similarly are not white, but yellowish, hindwings 
pure white. Andalusia. Also here nothing definite can be laid down in regard to the distribution. It certainly 
occurs in Spain, Sicily (especially in the forms purpurascens and rufescens) and N. Africa. — jordana Stgr. is jordana. 
a further form, it is smaller with almost pure white hindwings. From Palestine (Valley of the Jordan). 
L. seposita Trti. (16 k) is a further genuine species. Forewings black-brown, veins and transverse lines seposita. 
grey, diffuse, the subterminal line consisting of yellowish white lunules, anteriorly to each of which there is 
a black cuneiform mark. The surrounds to stigmata are yellowish white. The grey fringes are intersected by 
white at extremities of veins. The transverse lines converge more closely than in the other species towards the 
inner margin and the pale inner marginal longitudinal streak is practically absent. Hindwings are greyer 
and the inner margin more definitely hairy, rather paler towards base. Posterior to discal spot there is a 
central line, that is parallel to the one at margin. From Sicily (Nicolosi). — rhodina Trti. from Calabria, rhodina. 
Cosenza is more suffused with rose and therefore the colours appear richer. Veins and markings are deeper 
yellowish white and not so grey. 
L. turatii Schaw. (16 k) appears to me to be a genuine species. It is probably closest to seposita. Ground turatii. 
colour is darker, black-brown, only the orbicular stigma is somewhat yellow. Hindwings are much darker, 
often having a straight dark transverse band. Underside, especially of forewings, is much blacker. From Corsica 
(Evisa and Vizzavona). 
L. machlyum Trti. (16 k). This is a smaller, more gracefully built species of uniformly pale brown machlyum. 
ground colouration, but with darkened central area between stigmata and inner margin, in which all the pale 
veins are absent. The stigmata are purer white with fainter centres. Reniform stigma wider and inclined to 
be rectangular. The outer transverse line is less sharply dentate, subterminal line is formed of white lunules 
as in hispidus. Hindwings not pure white, but brownish. — luteosignata Trti. is a form with yellowish stigmata lutco- 
and subterminal line. Apparently widely distributed in Algeria and deemed by Rothschild to be hirsuta. signata. 
Also occurring in Cyrenaica (Berea). 
L. rosinae Bhtsch. (161) has narrower wings with more oblique margin, coarsely scaled, brownish grey, rosinae. 
both transverse lines sharply dentate, stigmata faintly paler, ground colour dark grey-brown before and beyond 
the orbicular stigma. Subterminal line irregularly dentate with anterior blackish sagittate streaks. There 
are small black triangles before the white marginal line. Fringes intersected bv pale patches. Hindwings pale 
brownish grey, almost whitish with discal spot and blackish marginal line. From Russian Armenia (lvulp) 
and bred from larvae by Mrs. Rosine Korb. 
L. rasilis Drt. (16 1) is very close to rosinae. Head and thorax pale brownish, abdomen somewhat paler, rasilis. 
Forewings pale brown, densely speckled with brown, darkest in central area. Transverse lines black, the post-
