N.N .W. of Great Natunas. The wind was fresh and blowing 

 from off the Cochin China coast : about 10 a.m. we noticed 

 many small moths settled over the deck and all in perfect con- 

 dition, as if just hatched. At first we suspected that they 

 were bred in the ship, but soon discovered that they were 

 coming on board in numbers. For about five hours we 

 noticed these moths in great numbers travelling from about 

 N.N.W. to S.S.E. They had the power of resting on the 

 surface of the sea — even in the broken water around the bows 

 of the boat — and then rising and continuing their journey. 

 There were several other species in small numbers, and among 

 them the delicate little plume moth which I send. I think 

 these moths must have come from off the Lower Cochin China 

 coast, and, if no bad weather turned up, would reach the 

 various islands, or even Borneo, in fair numbers. 



" What surprised us most was the beautiful condition so 

 many of them (oi", to be more exact, nearly all) were in, showing 

 that their long journey had had no ill effects upon them." 



Professor Poulton said that the species, of which a list is 

 given below, had been kindly named for him by Sir George 

 Hampson, and the " Plume " by Paymaster T. Bainbrigge 

 Fletcher. 



Schoenohius hipunctifera, "Walk., 7 specimens. 



,, incertulas, Walk., 7 ,, 



Glyphodes celsalis, Walk., .1 ,, 



Alitcita niveodaciyla, Pag., .1 „ 



The specimens had unfortunately been attacked by " pests," 

 so that the majority were in bad condition. The small and 

 delicate white " Plume " had escaped this injuiy and was 

 beautifully preserved. 



The species named above possessed the following distribution 

 as shown by the series in the British Museum. 



S. hi20unctifera : — India, Ceylon, Assam, Burma, China 

 (including places so distant as Omei-shan and Chusan 

 Islands), Formosa, Singapore, Java, Sumatra, Borneo. 



S. incertulas : — India, Ceylon, Burma, Singapore, Borneo, 

 Java, Cassini Island (N.W. Australia), 



Glyphodes celsalis : — India, Ceylon, Assam, Burma, China
