544 FAUNA HAU'AIIENSIS 



question open till we have more conclusive evidence. When I described the species I 

 considered it to be an introduced one, and I still entertain this opinion. Indeed as 

 Trogophloei are very readily distributed by artificial means, and as the three Hawaiian 

 species are apparently nearly confined to Oahu, I expect they have all been introduced. 



Hal. Oahu. On the margins of waters (Blackburn): Wailua, in. 1901, Waianae 

 coast, I. 1 90 1, mts. 3000 ft. 1892 ; (Perkins). 



(2) Trogophloeus tontinalis. Sharp. 



T. fontinalis Sharp, Trans, ent. Soc. London, icSSo, p. 52. 



M. Fauvel has suggested that this may be T. iiisiilaris Kr., a species which he 

 informs me is widely distributed. The type of T. insiilaris was a Grecian specimen, 

 and the original description does not accord at all well with T. fontinalis :. so that the 

 question must remain open. T. fontinalis has not been met with by Perkins and it is 

 probably rare and local in Oahu. 



Hab. Oahu, on the margins of running waters in the mountains (Blackburn). 



(3) Trogophloeus abdonnnalis, Sharp. 



T. abdoviinalis Sharp, 1. c. 



M. Fauvel informs me that this species is also found in the Antilles. 



Hab. Oahu, Molokai. — Apparently a coast species.- — ^Oahu (Blackburn and 

 Perkins). Molokai, sea level, x. 1893 (Perkins). 



Tribe PAEDERINI. 

 LiTHocHARis, Lacord. 

 Lithocharis Lacordaire, Faun. Ent. Paris, 1835, p. 431. 



(i) Lithocharis vilis, Kr. 



Lithocharis vilis Kraatz, Arch. f. Naturges. x.w. i. 1859, p. 139. 

 Lith. fuscipennis Kr. .^ Sharp, Tr. Dublin Soc. sen 2, 111. 1885, p. 223. 

 This species has not been found by Dr Perkins. It is a widely distributed form. 

 The above synonymy I owe to the kindness of M. P'auvel. 



Hab. Oahu, Honolulu (Blackburn).
