ZOOLOGICAL NOTES ON COLLECTING IN BORNEO. 427 



common Euplceines, E. claudius mulciber and E. diocletianus lotvi, 

 neither of them represented by more than two or three indivi- 

 duals. The big yellow hind winged Papilio, P. amphrysus (or 

 possibly P. helena), occasionally flew up and away again at once. 

 On the felled trees a little Arhopala (probably A. apidanus) was 

 a frequent visitor, with one or two other Lycasnids, among which 

 was the rare Thecline, Bindahara phocides. 



Our Dayaks made a small clearing on the summit plateau 

 across the southern end, which there tapers to a point. Each 

 man armed himself with an extra long stick, about fifteen feet 

 long, to which a butterfly net was attached ; great was the 

 excitement on the approach of some great buzzing insect, which 

 more often than not succeeded in evading the four or five nets 

 waving clumsily after it. Big Swifts, Ghcetura gigantea and 

 C. leucopygialis, hawked insects up and down in front of the 

 clearing, accompanied by some big dragonflies on the same 

 work. The ascent to this spot from the next plateau immediately 

 below was very steep, and, in descending, one or two places were 

 particularly nasty ; however, the ever-ready hand of an attentive 

 Dayak helped one to overcome these difficulties, and certainly the 

 magnificent view, not to mention the excitement of annexing 

 new species every two minutes, more than repaid one for the 

 exertion. 



On one side we could see for miles into Dutch Borneo — great 

 stretches of untouched jungle, with here and there a little patch 

 of lighter colour indicating some native village and paddi farm. 

 On the Sarawak side we could see the whole of our course from 

 the Sadong; but to the immediate north and north-west 

 Mt. Sepedang and the eastern slopes of Mt. Penrissen obstructed 

 further view. 



The weather was particularly kind to us throughout our stay, 

 nearly every morning being fine ; in the afternoon, however, we 

 usually had some rain — one or two nights we had a heavy storm, 

 which brought down trees and branches in the neighbourhood, 

 besides pointing out a few leaks in our hut. The little stream 

 near by afforded us beautiful drinking water and a very refreshing 

 cold bath ; this latter a much-appreciated luxury in the tropics, 

 where cold baths are usually inclined to be lukewarm. 



All good things have to come to an end and early in the
