1889.] LEPIDOPTERA OF JAPAN AND COREA. 481 
M. divergens in another. For instance, a specimen, which as far as 
regards the relation of inner and outer stripes is of the divergens 
form, has the outer stripe regularly denticulated. Another example 
with most of the typical characters has the reniform quite as large 
as any specimen of M. divergens. 
The inner stripe is ill defined in some specimens, and in others it 
is entirely eliminated, whilst the outer stripe may or may not be 
denticulated ; further, the outer stripe is, in three examples, only 
faintly indicated and in two others is quite absent. The colour and 
markings of secondaries are subject to much modification on both 
surfaces.

I took specimens at Gensan in July. 
The primaries vary in colour from chestnut-brown through 
ochreous brown to ochreous grey; the transverse lines, usually dis- 
tinct, are sometimes only faintly visible, and in one specimen from 
Gensan almost entirely obliterated. In this last example the median 
nerve and branches are whitish.
