Euxestus minor Sharp, Tr. Dublin Soc. iii. 1885, p. 145, and PI. IV. fig. 14. 



We have received 7 specimens. 



Hab. Probably found outside the Hawaiian Archipelago : within the latter only- 

 known so far from Oahu (Blackburn) ; mts. near Honolulu, and Waianae mts. 

 (Perkins).

Eidoreus minutus Sharp, 1. c. 



The wings in this species are extremely transparent ; there is a more strongly 

 chitinised part, containing one or more nervures, along the anterior margin, extending 

 somewhat over \ the length of the wing : there is also a nervure, running diagonally 

 from the base to a point on the hind margin somewhat over \ the distance from base 

 to apex. No other nervures are visible. At the point where the diagonal nervure 

 touches the hind margin, the latter has a marked angular indentation. Just on the side 

 of this indentation, nearer to the base of the wing, is a brown pigmented patch. The 

 whole posterior margin bears moderately long hairs. 



Hab. Oahu. Two specimens (Blackburn) ; also one specimen from Honolulu, 

 and one from the Waianae mts. (Perkins). 



Fam. CORYLOPHIDAE\ 



Sacium Leconte. 



Sacium Leconte, P. Ac. Philad. vi. 1852, p. 142; Matthews, Monograph of 

 Corylophidae, 1899, p. 40. 



We have received specimens of a species of this genus. Comparison with the 

 species in the British Museum of Natural History, which include the collection formed 

 by Matthews, shows that these specimens cannot be placed in any described species. 

 The species undoubtedly belongs to this genus, for it has eleven joints in the antennae, 

 the eighth (just before the club) being very short and transverse ; and the mouth-parts 

 are of the type shown by Matthews in PI. I. figs. 4, 5 and 6 of his monograph.
