above, the ferruginous markings at llic aiiul angle and lobe of the liiud wing more distinct, 
the latter with a prominent black spot in the middle." (de Nici'vilh.) 
This species has been recorded by Pryer from Yamato and the Province of 
Satsuma, Japan ; it is also common in the Loochoo Islands. In Western 
China it occurs plentifully throughout the summer. Both the white and 
ochreous forms are found in about equal numbers, in the same localities and 
at the same times, and are represented by botli sexes, although tlie females 
seem to be much scarcer tlian the males. 
I have examined large numbers of Cliincse specimens, but none of them 
appeared to differ in any way from Indian examples of the same species. 
According to de Niceville, the Indian distribution of C. thyodamas is as 
follows : — Himalayas, Assam, Khasi Hills, Cachar, Upper Tenasserim, Anda- 
man Isles, Bombay, and South India. 
C. thyodamas was accidentally included in the distribution table of my 
paper on the Rhopalocera of Japan and Corea as occurring in the latter 
country. 
In his remarks on this species (Rom. sur Lep. vi. p. 99) Ur. Staudinger 
seems to be very positive that it does not occur out of India.

forehead, staly, slightly hairy in front, more so on the sides and upper surface of the second

third joint less than half the length of the second, elongate-conic, the apex rather obtuse. 
" Antennce about three fourths the length of the body, rather slender, terminating in a short, 
somewhat pyriform club, of which the terminal joints taper to a point. 
' Thorax oval, moderately stout, hairy ; ahdomen stout, about half the length of the inner margin 
of the hind wing.
