fold, or the yellow costa ou uuder surface of secondaries as iu the type of 
viridis. 
Occurs at Chang-yang in Central China, and at Moupin, Wa-shan, and 
Chia-ting-fu in Western China. It flies in June and July, and in Central 
China is found at an elevation of 6000 feet.

llesembles Hestina assimllis, Linn., on the upper surface, but there is no trace o£ red markings on 
the secondaries. On the under surface this species comes nearer to II. nigrivena, Leech 
(Entom. xxiii. p. 31), but the colour is greener; on the secondaries there is a black fold-line 
in submedian interspace ; the venation of all the wings is narrower, and the basal portion of 
costal area is less conspicuously streaked with black. Head black, but not spotted with white ; 
thorax and abdomen black, narrowly striped with whitish. 
Expanse 79-82 millim. 
This species varies in the amount of black on the upper surface of all the wings. The discoidal 
streak of primaries, more or less suffused with black, is generally divided into two parts, but 
sometimes this streak is entire, with a deep, or shallow, incision about the middle of its upper 
edge. On the under surface of some specimens the only dark markings are a black bar-like 
spot in the first median interspace of primaries and an indistinct tranverse bar in the discoidal 
cell ; the median nervure, and its first and second branches, of tliese wings are broadly black 
{H. i/anl~owsJiiji, Grose Smith and Kirby, is of this form) ; in other specimens all the wings 
have grey-brown, broad, interrupted submarginal and narrower lunulated marginal bands ; 
the primaries have a large square black spot in first median interspace enclosing a spot of the 
ground-colour and an interrupted oblique blackish streak from its upper edge to the costa. 
Another form appears so distinct from eitlier of those just referred to that 
I describe it as — 
Yar. intermedia, var. nov. Blacker than the type on upper surface, and the greenish-white 
markings are more clearly defined. On the under surface the primaries are black, marked 
with greenish white almost exactly as above ; the secondaries are greenish white, with a large 
blackish patch from the middle of costa ; a broad fuliginous submarginal band, in which arc 
three or four white spots, and a broad lunulated marginal line of the same colour. 
Expanse 75-78 millim. 
Occurs at Moupin, Wa-ssu-kow, and Ta-chien-lu in June and July. 
Some specimens of H. subviridis approach very closely to H. zella, Butler *,
