DERMAPTERA 
Eleven species of earwigs are discussed below and three other 
female specimens that were examined from the island of Hawaii 
represent one or two additional but at present not determinable 
Hawaiian species of the genus Anisolabis. These in the opinion 
of the writer represent all the species of this order that have been 
taken in all Hawaii. 
Of these species, five are unquestionably adventive, while sev- 
eral more are probably so. Four are as yet known only from the 
Territory of Hawai, but all of them may have a distribution 
roughly parallel to that of the three species that are known to be 
represented as well on islands in the south Pacific. 
LABIDURIDAE 
PSALINAE 
ANISOLABIS  Fieber 
Three Hawaiian species have been referred to the genus Aniso- 
labis Fieber. One of these, annulipes (Lucas), has been placed by 
Burr in the genus Euborellia, a genus based on male genitalic 
features alone. It is possible that monographic study of this very 
large group will afford additional evidence, warranting the separa- 
tion of these genera and, consequently, we are in favor of recog- 
nizing Euborellia for the present. Unfortunately the male geni- 
talia have not been studied for the other species here recorded; it 
would therefore appear advisable to refer them to Anisolabis until 
that work has been done. 
All of these species are subject to variation, the least decided 
being in eteronoma Borelli, and it is almost certain that the records 
from Hawaii of maritima, littorea, and pacifica and the description 
of aporonoma are entirely based on material of the species here dis- 
cussed. It seems therefore that those names have no valid standing 
in the Hawaiian list. 
Many of the species have a wide distribution and are readily 
introduced by commerce into favorable regions. Thus, judging 
from the known distribution of annulipes, it seems probable that the
