This paper contains a description of the Lepidoptera, exclusive of the Tortricidse, 

 Tineidse, Orneodidae, and Pterophoridse*, of the Seychelles Archipelago, and of the coral 

 islands of Aldabra, Assumption, Cosmoledo and Astove, though the collections from the 

 three latter islands are too small to be considered representative. The collections from 

 the Seychelles were obtained very largely by Mr Hugh Scott, who spent eight months 

 (July 1908 — March 1909) in the group and devoted the whole time to entomological 

 collecting. Mr H. P. Thomasset assisted very greatly with the Lepidoptera from Mahe, 

 while Professor Stanley Gardiner obtained a considerable number in the high jungle of 

 Silhouette. Ten days' quarantine on Long Island, near Port Victoria, Mahe, gave me 

 an opportunity of observing the fauna of the low cultivated land, and I subsequently 

 spent three days in the high jungle of Silhouette, which was exceedingly rich in insects. 

 From the end of July to tlie middle of August I was engaged in investigating the 

 outlying sand cays, Bird and Dennis Islands, and obtained small collections on each. 



About five months (September 1908 — January 1909) were spent on the coral atoll 

 of Aldabra, 250 miles N.N.W. of Cape Amber, Madagascar, and a few days on each of the 

 neighbouring islands, during which period the greater part of the collection from that 

 region was obtained, though I am also much indebted to Mr Dupont for a collection 

 from Assumption (1910), and to Mr Thomasset for a collection from Aldabra made in 

 the spring of 1907. On my return from Aldabra, a fortnight spent with Mr Thomasset 

 at Cascade, almost on the edge of the indigenous jungle, gave me further opportunity of 

 obtaining some acquaintance with the Seychelles insect fauna. 



Mr Scott spent August and September in the high jungle of Silhouette, and the 

 remainder of the period on Mahe, while he paid short visits in December to Praslin, 

 Felicite and Marie Anne. His collections, by far the largest ever made in the archipelago,
