THE Curculionids here enumerated from the Seychelles, Aldabra, Chagos, and the 
adjacent islands number 134 species, 27 only of which can at present be identified with 
described forms. The presence of one entirely new group, the Phcenicobatina, including 
three genera and 28 species, shows that these islands have a comparatively rich weevil- 
fauna, now brought to light by Mr Hugh Scott's exhaustive methods of collecting in the 
mountain forests. Probably he is almost the first entomologist who has set to work to 
examine properly the leaf-bases of palms (more especially of the Coco-de-Mer) and screw- 
pines in these or any other tropical regions*. Hence, a very interesting series of minute 
forms has been discovered, and, as might be anticipated, they are nearly all new. The 
Cossonina, as usual in various Oceanic Islands (even in cooler regions like St Helena and 
New Zealand), are abundantly represented, and include 50 species, with ten new genera. 
The Trypetina and Antliarrhina (like most of the Phcenicobatina) are probably attached 
to palms, and doubtless endemic. Amongst the Cryptorrhynchina there is a singular 
dearth of apterous forms, one species only (an Acalles) being represented. The con- 
spicuous winged Otiorrhynchids, Cratopus spp., are, on the other hand, abundant, im 
individuals, both on the coast and in the mountains, though but few species are present. 
The apterous Hylobiina and Anchonina, insects living amongst dead leaves on the ground, 
are also characteristic weevils in the Seychelles, several species being common in the 
mountain forests. The three apterous Otiorrhynchids belong to as many genera, one of 
which seems to occur also in Madagascar. The Attelabine, Barina, Cyladina, and 
Calandrinze are either introduced forms, or belong to genera occurring elsewhere, in 
Ceylon, Madagascar, 8. Africa, &e. Out of a total of 134 species, at least 100 are probably 
endemic, and the entire group Pheenicobatina, so far as at present known, 1s peculiar 
to the Seychelles. Kolbe’s list (1910) includes 17 species only for the same groups of the 
Rhynchophora. 
The Hawaiian Islands possess almost the same number of Curculionidee [vide 
Perkins, Introd. Fauna Hawaiiensis, p. xxii. (1913) }-132 species, in 12 genera, endemic, 
and 14 species, in 9 genera, introduced.
