Arma pacifica, Stal, 1. c, 221. 4. 
Like the last this is also peculiar to the Hawaiian Islands. 
Though widely distributed it is not common, and frequents 
trees on the mountains.

Not being closely allied to any of the species in Stél’s 
‘Enumeratio,’ its place is between that author’s sections

amongst mixed herbage near the summit of a mountain-pass 
known as the “ Pali,” near Honolulu.
