Hebard—Dermaptera and Orthoptera of Hawaii 317 
Pronotum shining, thickly though minutely punctulate, these punctula- 
tions the sockets of minute but stout hairs, except on convex prozonal por- 
tion where the hairs are weaker and absent on the sulci, supplied near 
cephalic margin with a few bristles; length very slightly less than width; 
lateral margins parallel, rounding broadly into the broadly convex caudal 
margin; surface of pronotal portion moderately convex, with a medio- 
longitudinal linear sulcus and two weaker, shorter sulci on each side, which 
converge slightly caudad, remaining portions deplanate. 
Tegmina about twice as long as pronotum, with apices nearly trans- 
verse, showing very faint obliquity; shining, though minutely but thickly 
punctulate, these punctulations the sockets of minute but stout hairs and 
with a few bristles latero-cephalad and many along the caudal margin. 
Exposed portion of wings half as long as tegmina and _ similarly hairy. 
Abdomen with dorsal surface shining, supplied with even finer hairs than 
head; glands absent; distal tergite broadly and weakly impressed meso- 
caudad, caudal margin transverse, ventral surface more heavily hirsute, 
penultimate sternite with caudal margin transverse. 
Pygidium small, moderately convex declivent to lateral margins and 
base of apical portion, very slightly longer than broad, lateral margins very 
weakly concave, convergent to the apex, which is narrow but angulate 
emarginate, the latero-caudal projections thus formed being minute, acute- 
angulate. Forceps moderately elongate, as hairy as abdomen, proximal por- 
tion nearly straight, strongly triquetrous, distal third flattened oval in cross- 
section, curving very gently inward to the sharp apex; ventro-internal mar- 
gin with a minute flange beneath the pygidium, the margin of that flange 
suddenly and roundly terminated and alone visible from above, remaining 
portions of ventro-internal margin showing traces of very weak serrulation.” 
Limbs short, femora stout; first tarsal joint with length very slightly 
greater than combined length of the minute second and elongate third 
joints, hairy, its ventral surface with two rows of weak bristles and with 
an internal fringe of closely placed hairs, arranged in successive lamellate 
series. 
Description of 9 ; same data as for @, except taken October 28, 1920. 
Agrees with male except in the following features. Abdomen broader. 
Distal abdominal tergite smaller. Pygidium very strongly declivent, nar- 
row, fitting tightly between arms of forceps,” its ventral margin narrowly 
lamellate and horizontal, the caudal margin of this portion transverse be- 
tween the minute, dentiform, latero-caudal angles, from which the sides 
of this portion are straight and parallel proximad. 
Forceps straight when closed, leaving no intervening space,” curving 
inward slightly at apices; dorsal surface not flat as in male, internal 
“From this it would appear that some males of the species have this 
margin supplied with weak and widely spaced serrulations.

“The additional portions can only be seen when the forceps are 
opened to some degree. 
“In one female the forceps show a weak curvature and in this speci- 
men, when closed, would not fit tightly together throughout.
