tending from costa to first vein and interrupted by the neuration 
above ; outer marginal area black with a series of subapical white 
spots, the neuration on this portion of the wing is chocolate brown. 
Secondaries white with a broad black band on outer marginal area ; 
the space between the cell and vein 1) more or less suffused with 
fuscous ; venation on outer marginal area metallic blue and the 
anal angle is tinged with the same colour. Expanse 65—70 
millim. 
A long series, including both sexes, taken in June and 
July at Omei-shan, and one male from Chia-ting-fu, cap-

Hab. WESTERN CHINA. 
Allied to C. idxoides, H.-S., but, apart from the different 
colour of the primaries, it is at once separated by the 
crimson collar being without blue spots. 
242A. Chalcosia reticularis, sp. n. 
Q Head and antenne with green reflection, collar crimson. 
Primaries creamy white, venation broadly black, especially on outer 
area ; the basal third streaked with black between the veins, and 
there are two diffuse black transverse bands, the first oblique and 
the second undulated ; outer marginal area black. Secondaries 
creamy white with an indented black band from costa to vein 2, 
this is interrupted by the venation, which is metallic green on the 
outer arta of the wing ; fringes black preceded by a line of metallic 
green between vein 2 and outerangle. Under surface creamy white : 
primaries have a metallic green patch in the basal half of the discal 
cell and a black band, the latter interrupted by the venation, which 
is metallic green on outer portion of the wing: secondaries as above 
but the band is narrower. Expanse 88 millim. 
One female example taken by a native collector to the 
north of Ta-chien-lu. 
Hab. WESTERN CHINA. 
The species appears to be most nearly allied to C. 
idxoides, from Northern India.
