Three male specimens from Pu-tsu-fong, taken in June 

 or July. These differ from the typical form in the colour 

 of the abdomen, which is bright crimson. The colour of 

 the primaries is rather paler than in Indian examples, and 

 there are no markings about the apex and outer margin. 

 I propose the name carnea for this form. 



Distribution. SiKHiM ; Western China. 



497. Spilosoma soror, sp. n. 



3Iale. Primaries yellowisli-buff with an oblique, dusky, macular 

 band between veins 1, 2, and 5, which attains its greatest width 

 between veins 1 and 2. Secondaries whitish and latlier silky, with 

 two black dots towards anal angle, these are often absent. Under 

 surface as above. Thorax colour of primaries, head slightly paler ; 

 abdomen crimson with dorsal and lateral rows of black dots, anal 

 segment with white hairs ; femora of fore-legs crimson. 



Female. The dusky band of primaries has a curved extension to 

 the costa and an additional spot on inner margin ; terminal segments 

 of the abdomen white. 



Expanse 42 millim. 



Two males from Chia-kou-ho, one from Chia-ting-fu, 

 one from Ta-chien-lu, and a female from Che-tou. July. 



The blackish dots on secondaries are only present in 

 one example. 



Allied to S. janhoivskii, Oberth., but differs from that 

 species in its deeper colour, in the absence of discal spots 

 on either wing, and of the apical spots on primaries. 



Habitat. Western China.
