216 PERCY SLADEN TRUST EXPEDITION 



xxvi. 1902, p. 569), which includes all the species obtained in those islands by Voeltzkow 

 in 1895, together with all others known therefrom up to that date. The second is the 

 same author's paper on "Die Coleopterenfauna der Seychellen" (Mitt. Zool. Mus. Berlin, 

 V. 1910, p. 1), giving an account of all the species found in the Seychelles by Dr Brauer, 

 together with those collected there by earlier investigators. Both these papers contain 

 important descriptions of new genera and species. 



Types. As in the case of all the Entomological Collections made by the Percy 

 Sladen Trust Expedition, a first set of specimens including the Types of all new species 

 will be placed in the British Museum. A second set will be retained in the Cambridge 

 University Museum. 



Localities. At the end of the remarks on each species is given a list of the localities 

 whei-e it was found, together with dates or any further particulars when such are 

 recorded. In these lists, the dates " 1908," " 1909," or " 1908—9," given alone {i.e. not 

 followed by any collector's name) in any item, always indicate that the material was 

 collected by myself or by some of those who helped me while I was in the Seychelles : 

 similarly, " 1905 " always indicates that it was collected by the earlier Percy Sladen 

 Trust Expedition in H.M.S. " Sealark" : in all other cases, the collector's name is placed 

 in brackets at the end of the item. When a species is found outside the area of the 

 Expedition, the locality-list is followed by a brief summary of the external distri- 

 bution. 



I desire to express my indebtedness to a number of gentlemen who have given me 

 very valuable assistance. Monsieur P. Lesne has very kindly compared a number of 

 specimens with species in the Paris Museum, and I have also to thank Dr A. Sicard for 

 taking several species to Paris for purposes of comparison. Herr A. Schmidt has 

 examined several species of Aphodiini, on the generic position of which I was unable to 

 decide without his assistance. Professor Kolbe has helped me in dealing with certain 

 Carabidse, as has also Dr W. Horn in connection with the Cicindela : and Mr G. J. 

 Arrow has given me his aid in the determination of a number of the Lamellicornia. 

 Lastly I have to thank Dr Sharp for much general assistance. Several other acknow- 

 ledgements of help are given below in connection with particular species. 



LAMELLICORNIA. 



25 species of Lamellicornia are enumerated in this paper as having been found in 

 the various groups of islands visited by the Percy Sladen Trust Expedition in 1905 and 

 1908 — 9. 23 of these were actually obtained by the Expedition : the remaining 2 species 

 {Rhyssemus goudoti and Lonchotus astovensis) have been previously recorded, but were 

 not found by the Expedition. Previously to the Expedition, 15 species were known 

 from these islands: 10 are now recorded for the first time, and 5 of these are new 

 to science, while for one new species it has been necessary to erect a new genus 

 (Nesohajdia). The 25 species are representative of 19 genera. The Lucanidee are 

 represented by 2 species of Figulus, the Scarabseidge as follows : Aphodiini, 9 sjiecies 

 representing 5 genera ; Orphnini, 1 species ; Dynastini, 8 species representing 3 genera ;
