Havine been requested by Mr Hugh Scott, the Curator in Entomology in the 
University of Cambridge, to determine the Platypodide and Ipide collected during 
the Percy Sladen Trust Expeditions to the Indian Ocean in 1905 and 1908—9, the 
following pages show the results of my examination of the material handed to me. 
The 1905 collection consists of only one specimen without antennee, but appears to 
be a species of the genus Triarmocerus, of which T. birmanus Eichh., has been described 
from Burma, and 7. cryphaloides Hichh., from Madagascar. 
In the 1908—9 collection, the Platypodide are represented by a single genus and 
species, and the Ipidee by 9 genera, comprising 22 species, of which 8 are new (as also is 
one variety of an old species). In addition, references are given to 3 other species (and 
a somewhat doubtful fourth) recorded as found in these islands by previous collectors, but 
not found by this Expedition, so that in all 25 (or possibly 26) species of Ipidz are 
enumerated from the Seychelles. 
It has been necessary to make a new genus, Sciatrophus, for a very curious beetle 
found only at Praslin in the Vallée de Mai, and taken there solely from the leaf-bases of 
growing gf coco-de-mer ; nothing at all resembling this insect was found in any of the 
other islands, and for the reasons given below, the genus must be placed on the debatable 
land between the Curculionide and Ipide, at any rate for the present. 
There are a few species of the genus Cryphalus which are left undetermined ; 
Hichhoff described a good many single specimens from India and Burma, but as his types 
are lost or at any rate not available, no identification on his descriptions alone would be 
satisfactory. 
In this paper, Stephanoderes and Hypothenemus are not treated as subgenera of 
Cryphalus. i 
Types. A first set of the material, including types of all new forms, will be placed 
in the British Museum: a second set will be retained at the Cambridge University 
Museum.
