XLIII. — Neio Rhopa/ocera from Central Ceram. 

 By George Talbot, F.E.S. 



[Plates XIV.-XLX.] 



Early in ]9I9 Mr. J. J. Joicey sent three collectors to the 

 East, in the })ersoiis of Messrs. Felix, Charles, and James 

 Pratt. The two first-nauied had already had considerable 

 experience of tro|)ical collecting. It was decided that they 

 should attempt to reach the liigher slopes of the mountains 

 in the interior of Ceram, and, if successful, to spend a few 

 months making collections of Lepidoptera for the Hill 

 Museun). 



After much difficulty the three brothers established a camp 

 on the Blanusela Kange at GOOO feet, and were able to start 

 collecting iii October. The first collection made during 

 October and November contained a few striking novelties, 

 and these we describe in the present paper. A much larger 

 collection of about 15,000 specimens is on its way to us, and 

 consists largely of moths. 



Messrs. Pratt have recently left Cerani for Dutch New 

 Guinea, where the search for Lepidoptera is to be carried on 

 in an almost unknown territory. 



The types of the forms here described are in the Hill 

 Museum, Witley.

The nude of this magnificent species is the most interesting 

 discovery made by Messrs. Pratt on Ceiam. Although the 

 colour and pattern exhibits a relationship to t\\t goliath group
