The following facts can be summarized from the above table : 



The single species of Cicindela occurs, under two slightly different forms, in the 

 Seychelles, the Farquhar Group, and the Aldabra Group : the Seychelles form is described 

 for the first time in this paper, and I am obliged to refer to it the single specimen from 

 Farquhar, though one would rather expect specimens found in that group of islands to 

 belong to the form that is found in Aldabra. 



9 species of Carabidee have been found in the Seychelles, and 6 in Aldabra. Only 

 2 species {Tetragonoderus bilunatus and Tachys bibulus) have been found both in the 

 Seychelles and in Aldabra, and one of these {Tetragonoderus bilunatus) occurs also in 

 Coetivy, the Amirantes, and the Farquhar Group. 2 other of the species found in the 

 Seychelles {Hypolithus seychellarum and Stenolophus fulvipes) occur also in some of the 

 other islands, though they have not been found in the Aldabra Group : and one of the 

 Aldabra species {Dioryche interpunctata), though it has not been found in the Seychelles, 

 has yet been found in the neighbouring island of Coetivy.
