BY 

 J. R. H. NEERVOORT VAN DE POLL. 



Not being a])le to publish already now on the Nias insect -

Uuthalia Saidja, v. d. Poll. 



A most conspicuous local-race of E. Duiiya D. & H. , whicli I 

 consider the more interesting as hitherto Bivuija might have been

 Borneo and Malacca, I had an opportunity of examining, do not 

 differ to any extent and according to Dr. Staudinger specimens 

 from Palawan also agree with the typical form. 



E. Saidja is rather of a darker groun-dcolour suffused with 

 purplish, chiefly towards the outermargin of the anterior wings, 

 which have the apex much paler, opalescing, and the costal 

 as well as the extreme border of the outermargin greenish. The 

 white-centred spots placed exactly as in Duui/a but those of pri- 

 mei'ies considerably larger, with the exception of the cellular one, 

 which is so much reduced as to be hardly perceptible ; their colour 

 is of a purer white neither greyish nor yellowish but rather with 

 a somewhat pearly luster. Between these spots and the row of 

 indistinct blackish submarginal markings, the anterior wings are 

 crossed by a broad creamy-white belt ; moreover there is close to
