Hebard—Dermaptera and Orthoptera of Hawaii 321 
longer than the combined length of the succeeding tarsal joints and the 
bristles on its ventral surface are heavy. 
Allotype: @ ; same data as type. [Hebard Coll.] 
Differs from the male in the following characters. Abdomen broader. 
Distal tergite with a low and feebly striate, transversely oval convexity 
above the base of each arm of the forceps and bearing mesad on the caudal 
margin a small but conspicuously projecting node, directed dorso-caudad. 
Pygidium about as wide at base as an arm of the forceps, strongly 
declivent and showing a strong transverse convexity; with a very narrow, 
transverse horizontal flange at apex ventrad, terminating on each side in a 
minute point, which is concealed except when the forceps are somewhat 
opened. 
Forceps well separated, with a weak curvature, as in the male; dorsal 
surface flattened proximad, narrowing to distal portion and there terminating 
at the external margin; internal surface deplanate in proximal three-fifths, 
with dorsal and ventral margins coarsely and irregularly denticulate, thence 
with ventral margin developed into a weak flange, its margin slightly irregu- 
lar, terminating near apex of forceps.

The great individual size variation, sometimes found in species 
of Dermaptera, is well exemplified by the females measured.

portions of wings similar, but occasionally of a faintly darker shade. An-
