NOVITATES ZOOLOGIOAE XXII. 1915. 105 



ON LEPIDOPTERA FROM THE ISLANDS OF CERAM 

 (SERAN), BURU, BALI, AND MISOL. 



By the Hon. WALTER ROTHSCHILD, F.R.S., Pn.D. 



THE material I am describing was collected during the " II. Freibnrger 

 Molukken Expedition," by Herr Erwin Stresemann, and, after the Expe- 

 dition had split up, by Dr. Tauern. The fact that Herr Stresemann was an 

 ornithologist and Dr. Tauern a geologist accounts for the disproportionately small 

 number of species of lepidoptera compared with the fine collections of birds described 

 in the preceding volumes of Novitates Zoologicae. That a large number of the 

 specimens are defective is surely due to the season and the inexperience of their 

 native hunters. 



The most remarkable discovery faunlstically was undoubtedly the capture on 

 Ceram of Papilio ( Troides) procus and Papilio weiskei stresemanni, both belonging 

 to types hitherto considered exclusively Papuan. 



I have arranged the Rhopalocera and Gnjpocera approximately according to 

 " Seitz," and the Heterocera according to Sir George Hampson. There are of 

 Rhopalocera and irri/pocera from Ceram 140 species and subspecies, from Burn 17, 

 and from Bali 87, all collected by Herr Stresemann, while from Misol there are 48, 

 collected by Dr. Tauern. The total number of species of Rhopalocera and Gnjpocera 

 is only 286, owing to several being common to two or more islands. It is curious 

 that — in spite of the fact that Amboina and Ceram have furnished large quantities 

 of species from the time of Linnaeus, and even Seba, for more than 180 years — 

 there should still be large and conspicuous novelties on the latter island.

The specimen had slipped sideways in the box, so that we could not decide for 

 certain which of the three localities in Ceram it came from ; but I have no doubt 

 that, like P. weiskei stresemanni, it came from above 1000 metres in Central Ceram.

It is a great pity no c? of this remarkable species was obtained.

The single ? here enumerated agrees exactly with the S ? collected by Doherty 

 at Kapaur and those collected by the Pratts at Fak Fak and in the Ninay Valley. 

 Whether, as in the case of other species of this group, the c? will prove very different 

 remains for future collectors to discover.
