Of the two species already discussed in Vol. 2, p. 167: glasunovi Gr.-Grsh. and (dice John we are now 
giving illustrations, alice on pi. 49 b does not give the true shade of colour and just in the colour there is the 
essential difference between alice (10 b) and glasunovi (10 b). The $ of alice is more red-brown and larger 
than the <$. 
15. Genus: Oastropacha 0. 
G. quercifolia L. (Vol. 2, p. 168, pi. 27 d, e). — A hybrid johni Frings from a crossbreed of quercifolia johni. 
d X populifolia $ was bred, which is a midway form between the parent forms. The ground colour is a mix¬ 
ture of the brownish quercifolia and the reddish populifolia colours. There are scarcely any traces of an inherited 
bluish sheen of quercifolia There is also little darkening on costa of forewings whilst however the dark 
longitudinal line on thorax is present such as always occurs in populifolia. The transverse lines of forewings 
are occasionally more like populifolia and again like quercifolia. On hindwings the median band is distinct 
and narrow as in populifolia, whilst in (quercifolia it is wider and more diffuse. The two dark shadow like bands 
extend only to the centre of wing. 
G. populifolia Esp. (Vol. 2, p. 169, pi. 27 c, d). From the neighbourhood of Berlin one occasionally 
gets reddish orange-yellow specimens which are much paler than normal and with very faint markings. They 
are named lutea Gloss. lutea. 
G. coreana Mats. Somewhat resembles quercifolia, but it is not stated in what particular it differs from coreana. 
populifolia, so that this description does not help us much. The slight dentations of margin are more like populi¬ 
folia. Ground colour of both wings is violet brown, slightly grey at margin. The inner and outer lines of fore¬ 
wings single, as in quercifolia. The much interrupted submarginal line is more like that of populifolia. Hind- 
wings broadly golden yellow at base and costa with a narrow clearly outlined median line and a wider diffuse 
band beyond same. On underside of forewings an angulated dark brown median band and on hindwings an 
arched central band and a straight outer one. 70—90 mm. Corea. 
17. Genus: Ocloiiestis Germ. 
0. pruni L. (Vol. 2, p. 170, pi. 27 f). — vulpecula DM. are extremely poorly marked specimens of this vulpecula. 
otherwise little variable species. The inner line is quite absent, the outer one very delicate. — ambitiosa DM. amhitiosa. 
denotes the opposite, with normally heavy lines, the space between the outer one to the submarginal line is 
adumbrated with blue-grey scales. Similarly the margin to a light stripe behind the submarginal line. In this 
form also the hindwings have a distinct dark median band besides the outer one usually present. — In the south 
Ussuri territory and in Corea the race rufescens Kard. (10 c) is distinctly darker red. The inner line is angul- rufescens. 
ated below the costa and is straighter, this characteristic however does not always occur. 
18. Genus: Deiiclrolisims Germ. 
On account of the great similarity and variability of the separate species it seems appropriate to repro¬ 
duce a table drawn up by Matsumttra. 
1. $ The 2 lowermost spots of submarginal row, oblique, not parallel to outer margin . . 2. 
— These 2 spots are situate vertically and almost parallel to outer margin.3. 
2. All lines on forewings close together. punctatus. 
— All lines on forewings widely separated . segregates. 
3. Apical pectinations of antennae almost as long as thickness of shaft of antennae . . pini. 
—- These pectinations are longer than the thickness of shaft of antennae.4. 
4. The pectinations are deep black. albolineatus. 
— The pectinations are brown to yellow-brown.5. 
5. The outer line double. The distance between outer and inner lines always further than 
to the submarginal line. sibiricus. 
— Outer line not double. The 3 lines named about equidistant.6. 
6. Outer margin of forewings somewhat undulate. Expanse 90—100 mm. superans. 
— Outer margin straight. Expanse 60—90 mm . jezoensis. 
Such a table can only be a general indication. It is impossible to fit all sub-forms into it, for instance 
superans is said to have a single outer line. Matsumttra however illustrates a superans-dolosa with a double line. 
D. pini L. (Vol. 2, p. 171, pi. 28 a). The profusion and variability of this species has brought an inund¬ 
ation of names. The 1st 12 forms dealt with here have been denominated by Ivramlinger and Kohler and 
we are making use here of their designations for the wing areas. Basal area expands from base to the inner 
line. Inner band lies between middle line and inner line, middle band from middle line to outer line, outer band
