A NOTE ON SOME DRAGONFLIES FEOM NEW 



BRITAIN. 



--;;-'- By Herbert Campion. 



Whilst going through the exotic Odonata in the Cambridge 

 University Museum of Zoology a few years ago, I found a small 

 collection made in New Britain by Dr. Arthur Willey, during 

 bis expedition to that and other islands in 1895-1897. These 

 insects were not dealt with in the "Zoological Piesults " of the 

 expedition (Cambridge, 1898-1902), and a list of them is now 

 submitted. 



The most interesting capture was a species of IdiocnemiSf 

 a genus of Agrionidfe not previously recorded from New Britain. 

 Dr. F. Pkis, to whom I sent specimens in May, 1914, was at first 

 inclined to regard the species as a new one, notwithstanding its 

 general agreement with the description of /. inornata, Selys, 

 from Karoons, Dutch New Guinea. It was not, however, until 

 the present year that it became possible to obtain fuller 

 information about De Selys' type, and that any degree of 

 certainty on the subject could be reached. In January last 

 I sent the accompanying figure of the terminal segment and
