Heterocerous Lepidoptera from Japan. 11 
Male and female. Tokei (Fenton); female, Yokohama 
(Jonas); male, Hakodate (Whitely). 
Until the arrival of Mr. Fenton’s collection, I always 
believed this to be a small variety of P. japonica, Motsch. ; 
it appears, however, to be invariably not only much 
smaller, but much paler than that species; the primaries 
also, as compared with the secondaries, being noticeably 
smaller. 
21. Porthetria hadina, n. 8. 
Lymantria funida $ (nec. 2), Butler, Ann. & Mag. Nat. 
Hist., ser. 4, vol. xx., p. 402 (1877). 
The male of P. fumida proves to be very similar to the 
female (Ill. Typ. Lep. Het., ii., pl. xxiv., fig. 4), although 
naturally much smaller and darker. In accordance with 
the rule now followed, the fact that I figured the female 
as typical of the species (thus restricting the name to 
that form) renders it necessary for me to rename the 
male described in the ‘Annals,’ as being distinct from 
the true male of P. fumida. 
P. hadina is referable to the P. dispar group, and is of 
about the average size of that species, but is of a. de- 
eidedly blacker colour, darker even than P. japonica ; 
the markings on the primaries consist of two incurved 
widely separated zigzag blackish lines, which limit the 
central third of the wing, and enclose a broad irregular 
diffused band of the same colour, and of a rather broad 
blackish border, with irregularly sinuated internal edge ; 
the ground colour of these wings is olivaceous-brown ; 
the secondaries are of a uniform dark brown colour ; 
the fringes of all the wings are brown spotted with 
black. In some respects P. hadina is perhaps nearer to 
P. eremita of Europe. 
22. Porthetria lucescens, n. s. 
Allied to P. asetria (Hubner, Exot. Schmett., i1., 
pl.178; 1806), but larger, the dots near the base replaced 
by a single zigzag brown line; the line which crosses 
the cell placed at nearly twice the distance from the two 
contiguous discal lines, the latter less incurved towards 
the base; secondaries pale shining greyish testaceous 
instead of yellowish white; no distinct submarginal 
undulated stripe, but the apical border broadly greyish ; 
disco-cellulars grey ; expanse of wings, 1 inch 9 lines, 
One male. Tokei (Fenton).
