Ex. Schmett., p. 145 (1886), states that iV". dahana, Kheil, Rhop. Nias, 

 p. 24, n. 57, pi. V, fig. 27 (1884), equals N. paraJca. It is also 

 allied to Neptis hieiij Oberthiir,* from Ta-Tsien-Loti, Western China, 

 (sex not stated, now whether it is a true Neptis or a. Hahinda), from 

 which W. aurelia may be at once distinguished by the tawny markings 

 of the upperside being nearly twice as extensive ; on the underside 

 of the hindwing the disposition of the bands seems to be quite differ- 

 ent. The drawing here reproduced has been submitted to Dr. 0, 

 Staudinger, who states that it certainly represents his species. 



Described from three female examples in my collection from 

 Tenasserim, and one male in Captain E. Y. Watson's, the latter captured 

 in the Karen hills, 500 to 1,500 feet elevatiouj on 13th December, 

 1890. It does not differ from the female specimens described above, 

 except in having the wings somewhat narrower, and the apex of the 

 forewing less rounded.
