[The material here reported on forms part of the entomologi- 

 cal collections made by the Percy Sladen Trust Expedition 

 of 1905 and 1908-9 in the Seychelles and other islands of 

 the Western Indian Ocean. The late author of the paper 

 had already dealt with certain other families of Clavicorn 

 Coleoptera obtained in those islands, in the special series 

 of the Linnean Society's Transactions set apart for results 

 of that Expedition : see Trans. Linn. Soc. London, ser. 2, 

 ZooL, vol. xvi, pp. 93-116 (1913), and vol. xvii, pp. 

 141-159 (1914). The manuscript of the paper printed 

 below was received from him in Oct. 1915, but circumstances 

 hitherto have prevented its publication, while the author's 

 death on June 9, 1917, renders it a posthumous work. 

 The correction of the proofs has presented some difficulty, 

 therefore indulgence is asked, especially from French 

 readers, towards any textual and grammatical errors. 



I am responsible for the notes on localities, and on 

 reduction of wings and eyes in certain species (pp. 24, 41 , 45). 

 As in most groups, the greater part of the collection was 

 obtained in the endemic forests in the mountains of the 

 Seychelles proper. The spaces between the leaf -bases of 

 growing endemic palms and Pandanus proved a good 

 hunting-ground for these insects, the material of six of the
