10 TERACOLUS. 



greenish hind border ; these spots are situated between the third discoidal nervule and 

 the sub-median nervure. Expanse 1-6-1-75 inch. 



Female. — Very similar to the male, the broad marginal borders being browner 

 in tint. 



The underside does not differ from that of the male, with the exception that the 

 black spots on the primaries are larger. Expanse i"9 inch. 



The " dry-season " form is much lighter in colour, and looks very difi'erent from 

 the " wet-season " form, being not nearly so handsomely marked ; the marginal 

 borders are brown instead of black, and the spots on the primaries are paler, 

 inclining to buff instead of bluish-grey. At the base of the wings there is also a 

 slight dusting of grey extending along the costal margin, almost to the sub- 

 terminal row of dark spots near the apex ; the light oblong row of markings near 

 the apex is brought into relief by the pale brown of the hind margin on one side, 

 and by a row of black spots on the inside. 



The secondaries are plainly coloured, having the basal area pink, with a broad 

 hind-marginal border of brown. 



The under-surface is suffused with pale pinkish buff, becoming more yellow 

 towards the base of the primaries ; the black spots mentioned in the description of 

 the " wet-season " form are also smaller and browner in colour. Expanse I'O inch. 



Habitat. — North- West India.

This handsome species is one of four belonging to an entirely different section to 

 those already described. They are all distinguished by the heavily marked black 

 border on both wings. 



T. protractas is the only species of this group that has the salmon-pink extended 

 over the secondaries as well as the primaries. As will be seen by the above 

 descriptions, the " dry- " and " wet- " season forms are strikingly different, and it is 

 curious, as ]\lr. Guy Marshall remarks, that they have not yet been described as 

 distinct species. The late Captain Watson observes : " There are two well marked 

 seasonal forms which differ in the tone of the underside, which in the dry-season 

 form, obtained in November, is pale reddish-yellow, and in the wet-season form, 

 obtained in June, July, and August, is bright yellow." 



The range of T. jjrotractus is somewhat limited and is confined to North- Western
