we have now been able to examine material representing all of the 
very doubtful forms recorded, excepting Oniscosoma pallida Brun- 
ner and Conocephaloides hawatiensis Perkins, material of these 
species being at present lacking in the Hawaiian collections. Mr. 
Swezey has sent us for study a rich series from the collections of 
the Experiment Station of the Hawaiian Sugar Planters’ Associa- 
tion, the Territorial Board of Agriculture, the Bernice P. Bishop 
Museum, and from the private collection of Mr. P. H. Timberlake. 
The total probably represents a larger collection than had pre- 
viously been reported on, and we take the present opportunity to 
describe the new species included and make the numerous correc- 
tions necessary to place the nomenclature on a more secure basis. 
We take great pleasure in expressing our hearty thanks 
to Mr. O. H. Swezey for his exceptionally valuable aid, and also 
to Dr. C. M. Cooke, who has saved us many weary hours of search 
in locating the numerous localities recorded in the following pages. 
The conclusions in the present study are based on a compari- 
son of the material from Hawaii with that in the collections of the 
Philadelphia Academy of Sciences, where are represented most of 
the species with which Hawaiian forms have been confused. 
Much remains to be done, we believe, in determining the actual 
number of forms native in Hawaii, their geographic, racial, or full 
specific significance and their geographic distribution. In some 
species there are also striking, though less important, variants that 
can be satisfactorily understood only after much collecting has been 
done, with careful observation as to the effect of local environ- 
mental conditions, of soil, humidity, and vegetation. 
A total of six hundred and eighty-eight specimens has been 
examined, representing forty of the forty-one genera and all but 
two of the adventive species that have been recorded from Hawai. 
A large proportion of the native species have undoubtedly been 
represented, but the questionable validity of a number of described 
forms gives rise to doubt as to the actual number of species 
indigenous to the islands of Hawaii. 
The Hawaiian Dermaptera and Orthoptera are grouped as 
follows:
