No previously published records for the Odonata of the Aldabra 

 and Glorioso Islands appear to exist. Brief accounts of their recent 

 visits to the former are given by Mr. T. Risely Griffith and Dr. 

 Abbott in the Bulletin of Miscellaneous Information, Royal Gar- 

 dens, Kew, 1893, p. 152 et seq., but these contain nothing as regards 

 insects. A list of the plants collected by Dr. Abbott in the Aldabras 

 is given in the same Bulletin, 1894, pp. 146-150. Dr. Abbott's own 

 " Notes on the Natural History of Aldabra, Assumption and Glor- 

 ioso Islands, Indian Ocean," in Proceedings U. S. National Museum, 

 XVI, pp. 759-764, 1894, mention the Pantala Jiavescens referred to 

 in this paper. 3 



In the present paper seven species are mentioned. Five, from the 

 Seychelles, were already known to exist there, but some additional 

 details on their structure or relationships are given. Two species 

 are from the Glorioso Islands, one from Aldabra.
