204 Buacksurn— The Hawaiian Archipelago. 
In the part of the forests of Kauai that I visited the ohia lehua appeared to 
be the strongly predominant tree. I have no doubt but that there are hundreds of 
species still to be discovered on this island, which, it may be remarked, was the 
residence of Mr. Harper Pease, who sent several fine things to the British Museum 
some years ago. A journey on land completely round Kauai is impracticable, 
owing to the rugged and precipitous nature of the north-west coast, where 
travellers cannot pass between the mountains and the sea. 
The island Niihau, with an area of 97 square miles, lies west of Kauai, separated 
by a channel 15 miles wide. I obtained a fine view of it from Waialeale, though 
I did not land there. It has no very considerable hills, and is for the most part 
sandy, probably possessing a scanty fauna. 
Oanu. 
The area of this island is 600 square miles. It has two mountain ranges, both 
running more or less north and south, one of them on the southern portion of the 
east coast, the other on the northern portion of the west coast. 
The eastern range of mountains was the scene of the greater part of my researches. 
The higher summits of this range have an elevation of about 3000 feet, and the 
vegetation of the forests is extremely varied, the ohia lehua being much less 
plentiful than the koa and the kukui, and, at least, five or six other trees 
occurring in large numbers. I find, on reference to my journal, that I spent 
some portion of time (varying from an hour to an occasional twelve hours) in 
collecting insects on the eastern side of Oahu, as nearly as possible once a 
fortnight on the average through the six years that I spent on the Hawaiian 
Islands. 
The mountain range on the western side of Oahu rises to 4000 feet above the 
sea. I spent, in collecting there, four days in July, one day in December, one in 
April, and one in May, and came to the conclusion that each of the mountain ranges 
on Oahu has a considerable number of species peculiar to it. The western range 
bears the local name ‘‘ Waianae Mountains.” 
Mo.Loxkat. 
This island has an area of 270 square miles. It lies S.E. of Oahu, separated 
by a channel about 23 miles wide. I was able to pass only a few hours on it, 
during which I could not reach the forest ; on the plains there appeared to be only 
the ordinary species. As Molokai is separated from Maui by a channel hardly 
nine miles wide, and is not much further from Lanai, it is probable that much of 
its insect fauna is identical with that of the neighbouring islands—though I feel no 
doubt as to the existence of many species peculiar to it.
