Outer line dentate, black, regularly curved. It extends vertically from its termination at inner margin to 
costa; paler to the outer margin, a dark spot only from costa to vein 5. Besides a silvery spot near base, 
a small spot at lower angle of cell and obliquely inwards anteriorly two larger spots. 36 mm. Ta-tsien- 
lu. Plusiogramma transsecta Gaede (Vol. 10, p. 609, pi. 79 b) is possibly the same species. 
P. powelli Oberth. (15f) is perhaps only a pale form of pigra Hfn. Forewings grey-brown. The inner powelli. 
collateral of the inner line less widely cleft, the outer one already excurved in the cell and not only below 
same. The central line heavily incurved in middle and as pale as the inner line. Dark patches posterior 
to same at costa and inner margin. 'Beyond the outer line more or less rusty red. 28—34 mm. Lambese. 
P. konotlis Mats. Similar to cupreata Btlr. dealt with in Vol. 10, p. 647. Forewings with 4 white lines, Jcononis. 
of which the first 2 have dark outer edges and they are not angulated on submedian nervure. The 3rd and 
4th conjoin near anal angle and are interfilled there with black-brown. The 2nd and 3rd incline towards 
one another and almost form a junction on median nervure, the 4th is oblique, straight with dark edges on 
both sides. 24 mm. Honsho. 
The hybrid pigranocheta Klemann has recently been bred from a crossing of pigra $ X anachoreta $ pigrano- 
forming an addition to the hybrids of this Genus. It corresponds in dusky colouration to anachoreta and 
the sharply contrasting markings of pigra have not been transmitted. — Numerous secondary hybrids have been 
bred, which naturally differ very little from the corresponding progenitors. We mention the following: cur- 
tula $ x inversa $ (pigra <$ x curtula $) = curtinervis Federl. — raeschhei (curtula <$ X anachoreta r () 
X anachoreta $ = facilis Tutt. — inversa $ (pigra $ X curtula $) X curtula $ = inversula Federl. - 
prima (curtula $ X pigra $) x curtula $ = proavula Federl. — raeschhei $ (curtula <$ X anachoreta yj 
X curtula $ = raeschkula Federl. — difjicilis $ (anachoreta $ x curtula X curtula $ = similis Tutt. 
— Besides there is a hybrid of the 3rd degree: facilis X anachoreta $ = approximata Tutt, which natur¬ 
ally can no longer be distinguished from anachoreta. Federley has dealt with his breeding experiments fully 
in the “Archiv fuer Rassen und Gesellschaftsbiologie”, Vol. 8 (1911). 
42. Genus: I*y«liia Wkr. 
P. goddrica Schaus. Antennae of $ fascicular. Thorax grey-brown, abdomen olive brown with dark goddrica. 
transverse lines. Forewings pale rosy brown; dark olive brown on inner margin as far as the outer line, trans¬ 
verse lines similarly. A line on the median nervure and vein 4 to the margin with fine white lower edge. 
The outer line excurved behind the cell, thence to centre of inner margin. From centre of costa an incurved 
dark shade to median nervure and a similar line from submedian fold to base on inner margin. Beyond the 
outer line a double row of dots and marginal dots. An oblique shade from apex. Hindwings black-brown, 
d' 46 mm. Omei-shan. 
43. Genus: Sforraca Mr. 
N. longipennis Mr. (Vol. 2, p. 317, pi. 47 g). Actually retrofusca Joann., which was given under this relrofusca. 
species as a synonym, is in all probability a separate species. On forewings there is a small spot close to 
end of cell and another one below same. Behind the cell there is a large double spot between veins 4 6 
and a row of small spots to the apex. Hindwings brownish. The $ that possibly belongs hereto has darker 
forewings, orange-yellow with two dark spots before and again behind the disco-cellular nervure. 50 70 mm. 
Described from Tonkin, I have a specimen before me from Chekiang.
