Hebard—Dermaptera and Orthoptera of Hawaii 319 
Since Bormans’ first record of this species, from Hawaii as 
pygidiata, material from these islands has been referred incor- 
rectly to that species by all subsequent authors. It has been -defi- 
nitely recorded from Kona, Hawaii, and Perkins has stated that 
it is “widely distributed; found under the bark of trees in the 
mountains.” 
Burr has pointed out the differences between the Hawaiian 
insect and true pygidiata,’* but did not consider the former dis- 
tinct. We are convinced that the differences noted fully warrant. 
our present action. 
Though closely related to pygidiata, dubronyi may readily be sepa- 
rated by the paler and different coloration, decidedly shorter tegmina 
and wings, male pygidium with interval between distal projections less 
than that between these and the lateral projections, male forceps with 
meso-distal tooth the termination of a gradually widening flange and. 
situated ventrad rather than dorsad on the internal surface, and female 
forceps with internal margins heavily and irregularly serrate in proximal 
two-thirds, with a moderate and gradually narrowing flange of the ventro- 
internal margin in distal third and without a trace of median widening. 
Both sexes of pygidiata have been figured by Dubrony,™ 
the female of the present species by Burr.” 
In certain features, this very much smaller insect shows a 
somewhat similar development to that found in S‘phingolabis ha- 
qwatiensis (Bormans). 
Type: 6 ; Hauula, Hawaii. August 2, 1914. (O. H. Swezey.) 
{Hebard Coll.; Type No. 769.] 
Size small, form slender. Head with scattered pile and delicate, 
erect hairs, shining; distinctly but angularly cordiform, owing to the 
rather abrupt rounding of the latero-caudal portions of the occiput and 
a broad though distinct obtuse-angulate emargination of the caudal mar- 
gin; the medio-longitudinal suture weakly indicated in occipital portion. 
Eyes very small, scarcely over half as long as cheeks. Antennae with 12. 
or 13 joints; first large, about as long as third plus twice length of 
second,” expanding suddenly at end of proximal third, thence with sides

“Tt is clear that slight individual variation occurs in the length of 
the proximal antennal joints. In some specimens such differences are 
apparent between the antennae.
