Srom China, Japan, and Corea, 235 
Several specimens from Yokohama in Pryer’s collection. 
Mr. Smith took the species at Hakone in August, and 
I captured some examples at T'suruga in July and at Nikko 
in September. 
A fairly constant species, but the discal markings of all 
the wings and the marginal border of secondaries are subject 
to modification.

and Che-tou, taken in June and July.

Megalochlora mandarinaria, sp. n. 
Pale bluish green. Primaries, which are slightly concave 
below apex, have two transverse whitish lines, the first 
curved below costa and the second broad and slightly oblique ; 
there is a whitish line at end of the cell. Secondaries, which 
are angled in middle of outer margin, have a broad oblique 
whitish line. Fringes whitish. Under surface whitish, 
strongly tinged with green on primaries; the broad trans- 
verse lines of upper surface are reproduced.

One male specimen from Chow-pin-sa, taken in June. 
Hab. Western China. 
This species is somewhat similar to M. albovenaria, Brem., 
but the outer margins are not crenulate.
