less concave at ihe outer margin than in the North Indian and Chinese individuals. 

 Very small specimens are also often found in the Malay Peninsula. 



The specimens from the Thibetian frontier of China differ mostly in both sexes 

 from the Indian ones. In the male, the adnervular white stripes on the underside of 

 the forewings are much less tinged with yellow; indeed, in most examples the stripes 

 are unicolorous ; the abdomen has two rows of black spots on the underside (besides 

 the spots upon the stigmata) wliich are not present in the Indian, Central and Eastern 

 Chinese, Siamese, and Malaccan individuals. In the female, the black spots of the 

 underside of the abdomen are large and mostly merged together; the yellow mark of 

 the hindwings wliich stands behind the median nerxure is absent or very small- 

 :\Iost probably the aeaciia from Thibet proper and from the northern slopes of the 

 Himalaya will be more different from the type than those West Chinese specimens, 

 and will have to stand as a separate subspecies. 



S. Differs from T. rhddamd.nhis (Lucas) especially in the abdominal segments 

 being edged with yellow on the upperside, in the less jiroduceil abdominal angle of 

 the hindwings, and in the much sliorter basal partition of the median nervure 

 of these mngs. 



The forewings. wliich are louger than in rlntdaiaanius (Lucas), are rather 

 variable in shape; sometimes, especially in very small specimens, which are more 

 abundant in ]Malacca, Tenasserim, and Siam than in North India and China, they 

 are rather falcate. On the hindwings, the black scaling at the marginal spots 

 between the median branches is often rather extended ; in one ;\Ialaccan individual 

 there are also black scales within the cell ; many specimens have one or two minute 

 black subdiscal spots between the median nervules ; on the underside, which is devoid 

 of the admarginal black scaling, these spots are in some individuals from Cliina 

 rather large. 



5. The white stripes on the forewings are often very broad: in tlie Malaccan 

 specimens they are usually nan-ower than in the North Indian and Chinese examples ; 

 Felder's type takes in this respect an intermediate position ; the whitish border to 

 the cell of the forewings is in many individuals very broad, and is sometimes so 

 enlarged as to fill up neai'ly the whole cell, exclusive of two longitudinal streaks. 



The discal yellow spot in front of the subcostal vein of the hindwings is seldom 

 absent. The discal and submarginal black spots are never merged together, though 

 the two posterior pairs, between the median nervules, stand sometimes very close 

 together, and though the yellow markings between these two pairs are rather densely 

 overpowdered with black scales, especially on the upperside.
