L. oo>is«»(/«iS, liutl. — " Allied to L. vhitelyi, similar oa the upper surface, but differing below in 
the outer edge of the broad central belt of primaries being more transverse, obliquelj' ex- 
cised on the costa, very slightly zigzag on the second median interspace, bordered externally 
•with white as usual ; three decreasing ocelli in a lilac nebula towards apex, as in typical 
L. diana : secondaries with the zones of the ocelli and the submarginal band sUvery (or 
steel) blue instead of lilac, the third ocellus reduced to a mere point. Expanse of wings 
2 inches 4 lines. 
" It is possible that this may prove to be a beautiful variety of L. tvhiteli/i ; but it differs con- 
spicuously from our examples of that species, particularly in the vivid coloration of the 
ocellus-zones and submarginal band below. Nikko." (Buthr, A. M. N. H. (5) vii.) 
This species is common all over Japan during the warm weather ; it is 
very variable in size, shade of colour, and markings, and extremely difficult 
to take in good condition. I obtained specimens in the Corea at Gensan 
and Fusan. It is recorded by Mons. Oberthiir from Kouy-tcheou, Western 
China.

This species is very closely allied to serhonis, Hewitson, the principal point 
of difference being the more angulated central transverse line on the under 
surface of the primaries. Possibly it is only a local form of L. serbonis, of 
which species the following is the original description : — 
" Upperside rufous-brown ; both wings with two submarginal brown lines ; anterior wing with 
two indistinct pale spots on the costal margin beyond the middle ; posterior wing with a 
series of three black eye-like spots, and an ocellus near the anal angle. Underside rufous ; 
anterior wing with a zigzag black line and a largo pale spot, bordered on both sides with 
black within the cell ; the discocellular nervure brown, crossed beyoud the middle by a dark 
brown band, bounded outwardly, near the costal margin, by a dull white spot ; a white spot 
near the apex, and below two small ocelli, one of which is incomplete, followed by a band of 
brown and a submarginal baud also brown ; posterior wing crossed by two brown bauds, 
before and at the middle ; a brown line at the end of the cell ; a series of six ocelli, the first 
and fifth larger and more distinct than the rest ; the outer margin and a line near it black." 
{Hewitson, Ent. Mo. Ma<i. xiii. p. 151.) 
Oberthiir only describes the male ; the female is similar to the male, but
