colour that there is every opportunity for new denominations. The type (S') is stated to be orange-yellowish, 
which more or less agrees with the specimen kindly sent to me by the Tring Museum as albescens. It varies 
from creamy white to brownish yellow and such dark specimens have a shadow-like median band. Hindwings 
dusky brown with paler base and fringes. The £ is creamy white, the outer half of hindwings somewhat suf¬ 
fused with grey-brown. Palestine. 
L. staudingeri Baker (Vol. 2, p. 160, pi. 26 b). Besides the typical more or less yellow-grey form from 
Batna, Kenchela, there is a race in the Province of Oran (Aflou, Sebdou) in which the d is inclined to cinnamon- 
brown. This is named: castaneolavatus Rothsch. 
L. siniscalchii Trti. is similar in wing contour to pungeleri (9 f, g). Eorewing of d is pale rusty red and 
hindwings slightly paler. Base of both wings and entire body yellowish white. The species can therefore not 
be identical with pungeleri, as same has dark hindwings and it also cannot be a decolorata form, as the thorax 
is paler than forewings. In the 2 body and forewings have a brownish tinge, hindwings slightly paler. 40—50 mm. 
Cyrenaica. 
L. vitellius Oberth. This species is only illustrated by Oberthur and not described. Fore wings of d 
orange-yellow. Discal spot and marginal area browner. The edge of same runs parallel to outer margin and 
is situate much further inwards than is general in Lasiocampa species. This division of colouration is less di¬ 
stinctly marked on hindwings. On underside also an outer line is present on both wings and the space beyond 
same is darker. In other species when basal and marginal areas differ in colour, the margin is paler. Here the 
reserve is the case and possibly vitellius should not be classified here. East Thibet. It was already illustrated 
in Yol. 2, pi. 56 k, but in consequence of its uncertain classification it was overlooked in the text. In a spec¬ 
imen ex the collection of Stotzner the dark marginal area is wider than in our illustration and the basal area 
of forewings is darker. 
7. Genus: Macrothylacia Rmb. 
M. rubi L. (Vol. 2, p. 160, pi. 26 c). $ f. pallida Osth. This name has been given to $$ of such pale 
ground colour that the light bands merge in same. To judge from the original illustration they do nothing of 
the sort, so that the name simply applies to pale specimens. $2 in which the submarginal line is absent and 
having the space behind the outer line to margin uniformly pale, have still to be denominated. It should be 
mentioned here that a pallida d Tutt was already mentioned in Vol. 2, p. 161. Besides we have a pallida $ Th- 
Mieg. in Vol. 2, p. 448 without however a description. It was a stunted pale specimen devoid of any markings 
and of 55 mm expanse. — $ f. transfuga Krul. denotes $$ with bright rusty colour of the d and this is nat- 
urally very rare. — alfacaria Rbb. is a transition from korbi to bistrigata. Sierra cle Alfacar. It was discussed in 
Vol. 2, p. 448. —* The form korbi Grionbg. is dealt with in Vol. 2, p. 160; a sub-form to same is bistrigata Bub. 
(9 h). In both sexes it has transverse lines on forewings. The inner one however is distinctly excurved in the 
middle, the outer one has its main curve further from costa. According to Schawerda this form is synonymous 
with the following digramma-curvifascia. From the pair in my collection this does not appear to me to be so, 
as the ground colour is paler than in curvifascia and fringes of hindwings are not so pale. The shape of the 
lines appears to vary in digramma and this cannot therefore be used for a differentiation. 
K. digramma Meade-Waldo is held by Rothschild to be a distinct species. The inner line is as in bistri¬ 
gata, the outer one is excurved at costa, as it is at inner margin, in rubi it is only excurved at inner margin. 
The d quite corresponds to the $ which at first only was known, but this is not the reason for specifically sepa¬ 
rating same from the dimorphous form rubi, but the different course of the lines. It is quite possible that korbi 
is also a distinct species. — In Portugal there are two differing races in which the lines of forewings are heavier 
and fringes of hindwings quite pale: curvifascia Rothsch. with a dark chocolate-brown $ w r ith slightly paler 
hindwings. The outer line is not undulate, but uniformly excurved. The d has thorax and base of forewings suf¬ 
fused with yellowish. Hindwings darker than in the $. Cintra. — parallelifascia Rothsch. (9 h). The $ is even 
darker than in the previous form. Both lines are straight and parallel; the outer one is not as broad as in curvi¬ 
fascia, but broader than in digramma. The d I s quite similar to the thorax and base cf wings are not paler.

M. subpurpuria Btlr. (Vol. 2, p. 161, pi. 26 c). —- flavopurpurea 0. B.-H. (10 d) from Transbaikalia 
has both yellow bands of forewings wider than in dieckmanni Graes. from Ussuri. Also inner margin appears 
to be somewhat more yellowish. 
M. takamukuana Mats, is probably only a form of the preceding. Ground colour reddish brown, only 
slightly darker in median area. The inner line very diffuse, like in subpurpurea from inner margin to the spot 
in the cell, above same extinct, without yellow marginal spot. The outer line of the same shape as in subpur-
