hood of Berlin and has also been bred at Leipa in Bohemia. — In clausa Wrli. (15 h) of which we are illus- clausa. 
trating the type the reniform stigma is almost exactly of the same colouration as the transverse band in 
which it is enclosed, so that it is almost extinct, as its outline can scarcely be discerned. — In unifasciata unifasciala. 
Splr. only the inner transverse band is distinct, the outer one being obsolete; — in obscura Splr . the fore- obscura. 
wings are darkened, the bands suffused with brownish, the reniform stigma scarcely discernible, only a trace 
being visible, the orbicular stigma quite extinct. — In fasciata Teich the ground colour is normal, but the fasciata. 
transverse bands are darker and more distinct. — In ab. juncta Kauzki the anterior and posterior transverse junda. 
bands of forewings become confluent at inner margin. — ab. fuscostigmata Strd. has the reniform and orbicular fuscostig- 
stigmata of rusty colouration instead of greenish and these are further often with dark centre. ab. 
tangens Strd. is Strand’s denomination for a specimen illustrated by Nordstrom, showing a bred specimen tangens. 
from S. W. Norway, in which the two transverse bands of lines are conjoined below the stigmata by a 
dark shade. Possibly this is more an effect of the breeding rather than of the geographical origin (Ekero). 
_ ab. costaenigrata Kuj. are specimens in which the veins are densely darkly dusted in the outer area of costaenigra- 
forewings, so that light interstices occur, reminding one of the albingoradiata form of albingensis. 
P. Candida Houlb. Forewings like those of or, but hindwings which are faintly yellowish white in the Candida. 
disc, have a dark arched band before the margin. It differs hereby from all other species of the Genus. 
From Pedong, a locality of which I do not know the geographic position. — Some irish specimens were 
considered to be a separate race. They have a pearly white ground colour with almost completely sub¬ 
merged stigmata and dense black transverse lines which are confluent with the two transverse bands. The 
form has been named gaelica Kane although a similar specimen has been found in Scotland. On the gaehca. 
other hand the irish specimens are said to be of duller colouration without any rose or violet sheen, so that 
the stigmata are less prominent. This form is said to be a separate race and is named hibernica Trnr. I luberniea. 
should like to stress however that carefully preserved or, in darkened cabinets, lose their colour a little and 
fade in the course of time. Freshly caught specimens on the Continent are deep earthy grey, sometimes with 
a faintly olive greenish sheen. These however soon become more yellowish brown and after a few yeais in tin 
collection they are often of an ochreous brownish tone. — A further number of or forms have been desciibed 
from N. America. (Vide Vol. 6). 
P. ocularis L. (Vol. 2, p. 327, pi. 49 g). Of this widely distributed species Tixtt has named specimens 
with a rosy hue ab. rosea. — sareptensis Splr. is a form from S. Russia of paler grey ground colour with 
a lesser admixture of brownish. In it the two stigmata are rather widely separated. — As caucasica Krul. saie P ensis - 
probably a normal terrosa Graes . (Vol. 2, p. 327) has been described. — interrupta Splr. In this form the stig- interrupt. 
mata interrupt the transverse stripes of forewings. — ab. frankii Boegl. is a melanic form of ocularis, which frankii. 
almost exactly corresponds to the albingensis form of or, only the ground colour of forewings is not so uni- 
coloured black, so that one can still discern the dark transverse lines. This excludes mistaking the form for 
that of or. The type specimen was captured near Valencienne in N. France (this is an industrial town in 
the coal region). It is to be remarked that the markings of forewings in the type specimen are not quite sym¬ 
metrical (the pale stigmata on right and left wing being differently shaped) and the specimen was captured 
in July, so that it may belong to a 2nd generation, such as does not seem to occur everywhere. A number 
of specimens of this type have been observed in the same locality. 
P. ocularis X or $ has produced specimens which Tutt has named fletcheri. They resemble fletcheri. 
typical or, but the stigmata have dark surrounds. 
Genus: Spilobasis Houlb. 
Houlbert creates his Genus Spilobasis on ( Palimpsestis) basalis Wil. dealt with in Vol. 2, p. 3iS and 
a number of newer forms. This is however not based on any special structural characteristics, but on the 
presence of a large brown spot that embraces the inner 3rd of the forewing and is bounded outwardly by a 
more or less wide black line. 
S. basalis Wil. (Vol. 2, p. 328) (15 e). This species is described in Vol. 2, p. 328, but was not lllustra- basalis. 
ted. We are now giving an illustration. 
S. circumdata Houlb. (lie). Forewings with a whitish apical spot edged with blackish. The outer edge circumdata. 
of the dark basal spot is rounded and has first a pale and then a dark outline. Hindwings with marginal 
shade and in front of same a narrow premarginal band. Expanse 48 mm. The largest species of the Genus. 
W. China. 
S. flammifera Houlb. has the same shape exactly as circumdata (11 e) and also similarly wide forewings, tlammitera 
but the basal spot has not such a dark outer edge, the marginal area is_ not distinctly darker than 
the impurely grey cliscal area. Orbicular and reniform stigmata are faintly indicated and the blackish dots 
that indicate the disco-cellular in circumdata are entirely absent. Ta-tsien-lu.
