The collection of wingless insects described in this paper was made as part of 

 the work of the Percy Sladen Trust Expedition to the Indian Ocean in 1905 

 and subsequent years under the leadership of Professor J. Stanley Gardiner, 

 F.E.S., of Cambridge. 



Many of the specimens were collected by Professor Gardiner himself, others 

 by Mr. J. 0. F. Fryer ; but the greater part of the collection was obtained by 

 Mr. Hugh Scott, of the Cambridge University Museum. He spent eight months 

 on the Seychelles during the years 1908-9; and an interesting account of his 

 methods of work, with descriptions of the various islands visited, and the 

 nature of the mountain-forest regions from which most of the insects 

 come, will be found in a paper (1910) published in the Linnean Society's 

 Transactions, in which have appeared most of the results of the Sladen 

 Expedition hitherto issued (Gardiner and others, '07-'14). 



For the privilege of examining this highly interesting collection I am 

 indebted to the kindness of Professor Gardiner, to whom and to Mr. Scott my 

 best thanks are further due for much information willingly given, and for 

 patience under long delays due to the pressure on luy time of other work. 

 The publication of the paper by the Eoyal Irish Academy during war-time 

 has been much facilitated by a grant, which is gratefully acknowledged, from 

 the Council of the Eoyal Society. It is worthy of i-emembrance that a former 

 Secretary of tlie Academy, E. Perceval Wright,* made, nearly fifty years ago, 

 a biological expedition to the Seychelles, and described some plants from the 

 islands in our Transactions ('71). 



A general account of the area in which the collection was made has been 

 given in Professor Gardiner's paper ('06) on the Indian Ocean, and in his 

 contributions to the Eeports of the Expedition ('07-T4). The vast majority
