NOTES ON BUTTERFLIES FROM TENASSERIM. 331 



15. Apatura ambica, Kollar. 



Males only, from the Taungoo Hills, taken in March, and the 

 Thaungyin Valley, Middle Tenasserim, in January and February. 



16. Apatura sordida, Moore. 



One male from the Ataran Valley taken in March. This species has 

 hitherto been known only from Sikkim. 



17. EuLACURA OSTEUIA, Westwood. 



Thaungyin Valley, March. One male. I possess another male from 

 the Daunat Range. 



18. Sephisa CHANDRA, Moore. 

 Taungoo Hills, 4,000 feet, October. 



19. DiCHORRHAGIA NBSIMACHUS, Boisduval. 



Daunat Range, March and April. 



20. Stibochiona nicea, G. R. Gray. 



Taungoo Hills, 4,000 feet, Octoiior. Specimens from Burma and the 

 Malay Peninsula have the marginal white baud on both sides of the 

 hindwing more or loss developed, in e:!i:trome specimens very greatly 

 so, but every intergrado exists l)otween these voi'y white examples and 

 the normal form. The white form has been named S. nicea suhucula 

 by Herr H. Fruhstorfer, from Malacca (Berl. Ent. Zeitsch., vol. 

 xlii, p. 329 ( 1897 ). 



21. Neurosigma nonius, de Niceville. 



Taungoo Hills, 4,000 feet, April and May, several examples, all males. 

 This species was described in "Ann. and Mag. of Natural History," sixth 

 series, vol. xvii, p. 396 (May, 1896), from Karenni, Burma, but is not 

 mentioned by Mr. Moore, though described a year before 

 part xxviii of his " Lep. Ind. " was published. I think 

 Mr. Moore in '* Lep. Ind., " vol. iii, p. 79, &c., (1897), has confused 

 the species of this genus. N. doudledaii, Westwood, was described 

 from a female from Sylhet. I have both sexes from this locality, and 

 they agree with others in my collection from kSikkim, Bhutan, Joreh^t 

 in Assam, and Katha in Upjier Burma. Mr. Moore has figured the 

 female of this correctly on pi. coxviii, fig. 13, but its male he describes 

 as a new species under the name of N.fraterna, and figures it on the 

 same plate, figs. 2, 2a. My N. nonius is accurately figured on the 

 same plate, figs. 1, la, as the male of N. douhledayi \jic\. He gives 

 Bhotan [=Bhutan], the Khasia Hills, and the Chittagong Hills for
