This species lias been recorded under tlie name pacifica Stal from Fiji, 

 Tahiti, Raiatea and Bora Bora. Considerable confusion, however, exists with 

 regard to the closely allied and so-called cosmopolitan species Orthaea vincta 

 Say. It is fairly certain that the existing synonymy of the eight or nine species 

 under 0. vincta, is inaccurate, and it seems very probable that all the Pacific 

 Island records belong to 0. pacifica Stal. Kirkaldy {loc. cit.) records 0. vincta 

 as occurring in Fiji and synonymises with it his Hawaiian 0. periplanios, but 

 does not state on what grounds he relinquishes his former identification {Proc. 

 Haiv. Ent. Soc, I, pp. 150-151, 1907) as 0. pacijica Stal. If Orthaea parvula 

 Dallas has been correctly synonymised with 0. vincta then, judging by Dallas' 

 N. American type specimen, the Pacific Island species (0. pacifica) is perfectly 

 distinct from 0. vincta.
