Read 19th January, 1911. 



The consignment of specimens submitted to me contained 120 species in recognisable 

 condition, besides others representing perhaps half-a-dozen species probably new but 

 so far defective that they could not be advantageously described. The Seychelles and 

 Aldabra species being quite distinct, it will be convenient to discuss the general character 

 and relations of these two faunas separately, and afterwards to give a list of the whole, 

 with descriptions of the new species. 



I. FAUNA OF THE SEYCHELLES. 



No previous records of any species exist. In the present collection there are 

 111 species, of which 90 are unknown elsewhere and probably truly endemic; the other 

 21 are in my opinion probably all artificially introduced, judging from their known 

 distribution. Of these latter, 4 are domestic refuse-feeders, 5 are known to be attached 

 to cultivated plants, and the remaining 12 are in all likelihood similarly attached, but 

 their larval habits are at present unknown. 



The 90 endemic species are referred to 43 genera ; the high proportion of genera 

 would however undoubtedly be reduced by more extended collecting. Of these 43 genera, 

 29 are represented by one species each, 5 by two each, 4 by three each, 3 by four each, 

 and 2 by fourteen each ; these figures are suggestive, and therefore I will group the 

 genera on this basis, and consider their individual affinities and distribution. 



1. Apodemic Genera of one endemic species. 



Adoxophyes Meyr. Contains 11 Australasian species, of which 3 range into the 

 Indian region, and 1 European. 



Eucosma Hueb. Cosmopolitan ; the species is probably of African type. 



Bactra Steph. Cosmopolitan. 



Aristotelia Hueb. Cosmopolitan. 



Idiophantis Meyr. A small Indian genus, with 1 Australian species ; the species 

 is near Ceylon forms. 



Chaliniastis Meyr. A single Australian species is known. 



Onebala Walk. A charactei-istic Indian genus, most numerous in Ceylon.
