Buacxsurn—The Hawaiian Archipelago. 205 
Matt. 
The area of this magnificent island is 760 square miles. It lies S.E. of Molokai 
(which, as already stated, hes S.E. of Oahu.) It is separated from Molokai by a 
narrow strait, and is distant nearly 80 miles from Oahu. It consists of two 
masses of mountain, connected by a sandy isthmus about eight miles wide. The 
western mountain district consists of an irregular and very precipitous range, 
attaining an elevation of a little less than 6000 feet above the sea. The summits 
are extremely serrated and picturesque, but highly dangerous to ascend, as there 
are no well-defined tracks; and such tracks as there are in many places pass along 
the foot of sheer precipices from which stones often fall under the influence of wind 
and rain. I have never reached one of the highest of these summits, but have 
ascended about 3000 feet on several occasions, though without much entomological 
result ; but I have no doubt this was ‘“‘bad luck,” and that there are many interest- 
ing insects to be found here. 
The central isthmus of Maui is the only tract of low- ee land on the Hawaiian 
Islands that I have found profitable to work. I have spent very little time on 
it, but obtained several new coleoptera there, and a good many hymenoptera and 
lepidoptera. 
The eastern end of Maui is, in my opinion, the head-quarters of the insect fauna 
of the archipe.ago. It is formed entirely by that gigantic mountain Haleakala, 
with an elevation of 10,000 feet above the sea, the summit being occupied by the 
largest crater in the world. This mighty chasm is more than 2000 feet deep, and 
the distance around its margin is 29 miles. Volcanic action has long been extinct. 
As will appear on a reference to the catalogue of Hawaiian coleoptera, an enormous 
proportion of the most interesting insects occurred on the slopes of Haleakala. 
I only once visited the actual summit of the mountain, when I passed the night in 
a cave about 1000 feet below the highest point, and so devoted parts of two days 
to the exploration of the upper regions, which did not appear to be prolific of 
insect life. I found there, however, three species of carabidze (two of them repre- 
sented by single specimens—one, Mauna frigida, mihi, being of the highest interest) 
which I have not seen elsewhere. 
The following is an account of the time I spent on Maui. In October I passed 
four days there, during which I had little leisure for entomology, and what leisure 
I had was in short intervals, that only enabled me to visit the sandy isthmus and 
the lower slopes of the western mountains. The next visit I paid to the island was 
in February, when I spent fifteen days there, but during that period I was for the 
most part ‘‘on duty,” and then only able to make short excursions to the places I 
had visited before. I succeeded, however, in securing five days of leisure, which I 
devoted to Haleakala, during which I made the ascent (mentioned above) to the 
summit. My third visit to Maui was in April and May, when I passed a vacation
