1881. J OF AMURLAND, NORTH CHINA, AND JAPAN. 881 



Terias bethesba, Janson, Cist. Ent. ii. p. 272 (1878). 



As far as I can judge, this is a good species, intermediate between 

 T. Iceta and T, hecabe. The females are easily known, being of a 

 pale dull lemon-colour, more or less clouded with dusky scales. It 

 seems very like the figure and description of T. venata, Moore. 



T. hecabe, Linn. Mus. Ulr. p. 2 19 (1764). 



T. hecabeoides, M6n. Cat. Mus. Petr. p. 85, t. ii. fig. 2. 



IT, sinensis, Luc. Rev. Zool. 1852, p. 429. 



T. tnariesi, Bull. Trans. Ent. Soc. 1880, p. 198, t. vi. figs. 1-7. 



This wide-ranging and variable species is common in China and 

 Japan. Mr. Butler's paper on the Japanese species of Terias gives 

 full details of the variations and supposed hybrids between this 

 species and the next. 



I can see no reason for separating T. mariesi, the difference in the 

 shade of yellow which Mr. Butler relies on being variable in my spe- 

 cimens from Yokohama. 



T. ANEMONE, Feld. Wien. ent. Men. vi. p. 23 (1862); Butl. 

 Trans. Ent. Soc. 1880, p. 199, t, vi. figs. 8-11. 



Found in Japan, where, according to Mr. Butler, it connects 

 T. hecabe with T. mandarina by almost insensible gradations. 



With regard to this species Mr. Butler says (Trans. Ent. Soc. 1880, 

 p. 200) : — •' So far as I have been able to judge, the T. hecabe and 

 T'. mandarina of China are constant; the intermediate 2\ a?ie?Howe 

 does not come from that country, in which case hybridization cannot 

 modify the typical forms." 



Mr. Butler appears to have entirely overlooked the fact that the 

 type of T. anemone is expressly stated to have come from Ningpo. 

 It is also quoted in Fryer's list of Rhopalocera of Chekiang and 

 Kiangsoo provinces, in Ent. Mo. Mag. 1877, p. 52 ; and there are 

 specimens in Fryer's collection marked " Snowy Valley, Ningpo." 



T. MANDARINA, Dc I'Orza, Lep. Jap. p. 18 (1869) ; Butl. Trans. 

 Ent. Soc. 1880, p. 199, t. vi. figs. 13-18. 



Common in Japan, and occurs also in Formosa, whence two speci- 

 mens are in Fryer's collection. I have, however, seen none from 

 China, though Mr. Butler says it occurs there. 



With regard to the supposed hybrids named and figured by 

 Butler in the Trans. Ent. Soc. 1880, p. 197 et seq., I would call 

 attention to the utter want of evidence of the hybrid origin of the 

 specimens which he names T. hybrida (No. 7) and T. connexiva 

 (No. 12). Judging from the plates, the differences between Nos. 6, 

 7, 8, and 10 are extremely trifling, and equally so are the differences 

 between Nos. 12, 13, 14, and 15. We are informed that the absence 

 of 6 specimens out of 150, which are presumably represented by 

 figs. 7 and 12, will leave the three species as sharply defined as any 

 in the genus, and we are asked to believe without further evidence 

 that on this account the six specimens are hybrids.
