fold, or the yellow costa on under surface of secondaries as in tlie type of 
viridis. 
Occiu's at Cliang-yaug iu 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 cle\ ation of (JOOO feet.

Eesombles Hestina assi»iilis, Linn., on the upper surface, but thoro is no trace of red markings on 
the secondaries. On the under surface this species comes nearer to //. ni<jrivena, Leech 
(Entom. xxiii. p. 31), but the colour is greener; on the secondaries there is a black fold-line 
in siibmediau 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 generaUj' 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 tranvorse bar in the discoidal 
cell ; the median nervure, and its first and second branches, of these wings are broadly black 
{H. yanl-uwshji, 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 ail interrupted oblique blackish streak from its upper edge to the costa. 
Another form appears so distinct from either of those just referred to that 
I describe it as — 
Var. intermedia, var. nov. Blacker than the type on upper surface, and the grceuish-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 INIoupin, Wa-ssu-kow, and Ta-chieu-lu in June and July.
