L. de Niceville — List of the Butterflies of Bali, 8fc. [No. 4, 



almost imperceptible, differences that exist between them. But Dr. 

 Butler restricts T. hecabe to Hainan Island, and to Southern China from 

 Hongkong Island to Tonkin, so he would probably give another name 

 to our specimens from the Lesser Suuda Islands. In our opinion wet- 

 season T. hecabe from South China agrees with and is indistinguishable 

 from the only form of T. hecabe, which is the rainy-season one, found 

 in Lombok, and doubtless also in Bali, Sambawa and Sumba. 



257. *Terias blanda, Boisduval. 



Lombok (Fruhstorfer), Sambawa (Pagenstecher). Mr. Doherty says 

 he obtained " several varieties " of T. hecabe, Linnaeus, in Sambawa and 

 Sumba, which may include this species, but we have failed to recognise 

 it from the description. 



Dr. A. Gr. Butler places T. blanda as a synonym of true T. hecabe, 

 which, as noted above, he restricts to Hainan, South China and Tonkin. 

 But he keeps T. anemone, Felder, (with T. mandarina, De Lorza, 

 T. mariesii, Butler, T. hybrida, Butler, and T. connexiva, Butler, as 

 synonyms), as a distinct species from Japan, Chusan Island, and round 

 the south-eastern coast of China from Shanghai to Hongkong. The 

 dry-season form of the Hongkong T. hecabe is undoubtedly T. mandarina, 

 and de Niceville in Hongkong and Japan has caught evevy intergrade 

 between it and the broadly black- bordered T. hecabe. Therefore 

 de Niceville thinks that Dr. Butler's T. anemone is undoubtedly the 

 same species as true T. hecabe. 



258. Terias silhetana, Wallace. 



Lombok (Fruhstorfer). We have three females of this easily re- 

 cognised species from Lombok. Dr. Butler says that T. tecmessa, de 

 Niceville, is a dry-season form of T. silhetana, Wallace. This is not so, 

 if anything, it is a wet-season form with broad black borders. But 

 in North-Eastern Sumatra, from whence the types of T. tecmessa came, 

 no dry-season forms of Terias occur, as the seasons are practically 

 wet ones all the year round. 



259. *Terias vallivolans, Butler. 



Bali (Fruhstorfer as " Eurema " vallivolans), Lombok {Fruhstorfer 

 as Terias vallivolans). This species was described by Butler in Ann. 

 and Mag. of Nat. Hist., fifth series, vol. xi, p. 420, n. 71 (1883), from 

 Mindanao in the Philippine Isles. Mr. Distant in B,hop. Malay., 

 p. 306, n. 4, pi. xxvi, fig. 17, male (1885), describes and figures it from 

 Singapore, and says that he " Considers it probable that this is but 

 another variety of T. hecabe." Since the above was in type Dr. Butler 

 has placed T. vallivolans under T. silhetana, Wallace.
