The most comprehensive list of tlie Coccidae of Samoa which has hitherto 

 appeared is that by Doane and Ferris {Bull. Ent. Res., VI, pp. 399-402, 1916). 

 In the following list species mentioned in that paper are marked with an *, 

 the additional information gathered from an examination of the material col- 

 lected by Dr. P. A. Buxton and Mr. G. H. E. Hopkins being added where 

 necessary. A few other records, with references to the sources whence they are 

 culled, are added. Most of the species of Coccidae found on the Samoan Islands 

 have a wide distribution and have e"\ddently been introduced on. cultivated plants, 

 but a few would appear to be indigenous ; further collecting on wild plants will 

 doubtless reveal new and interesting forms and enable us to form an opinion as 

 to the affinities of the Coccid fauna. The total number known from the Islands 

 is now slightly more than that recorded for Fiji (27), and considerably larger 

 than for the Society group (19). 



In the case of the Aphididae and Aleyrodidae, the numbers are so few that 

 no comment is called for ; in the former family probably all the species have 

 been introduced recently, and in the latter, of the two species found, one has 

 travelled practically wherever its host plant, sugar-cane, has gone, and the 

 other, which is apparently new to science, appears to have affinities with a 

 Javanese species.

 sented from any of the Samoan Islands in the collections made by Messrs. Buxton 

 and Hopkins.
