Hebard Dermaptera and Orthoptera of Hawaii 367 
Femora unarmed. Cephalic and median tibiae with a minute, but 
stout, dorso-distal spine, the former with an oval, apert tympanum on 
the cephalic face. Caudal tibia with three small but stout external dis- 
tal spurs, of which the median is slightly the longer, and with two 
similar internal distal spurs, of which the dorsal is twice as long as the 
ventral; dorso-internal margin armed with (6 to 9) long, curved spines, 
and other minute, irregular spinulae proximad; dorso-external margin 
armed with more numerous, smaller® spines, the dorsal surface between 
these margins supplied with spinulae. 
Coloration of recessive examples ochraceous-buff tinged with ochra- 
ceous-tawny. Head ochraceous-tawny, with four, weakly defined, longi- 
tudinal lines on occiput of ochraceous-buff, the face russet. Pronotum 
ochraceous-tawny, with a pair of ochraceous-buff, elongate and nearly rec- 
tangular markings, which are situated meso-proximad and diverge strongly 
caudad, failing to reach the narrowly pale cephalic margin and more 
broadly pale lateral margins. Abdomen with a transverse line of darker 
flecks on each tergite, of which the median pair is the heaviest and with 
distal portion darkened. Limbs more strongly tinged with ochraceous- 
tawny. 
Coloration of intensive examples much sharper and more contrasting. 
Head shining blackish-brown, with two longitudinal lines on occiput of 
buffy (the external pair of lines obliterated); palpi, mouthparts and 
ventral surface buffy. Pronotum blackish brown, with paired markings 
and margins buffy and in striking contrast. Tegmina tawny. Abdomen 
and limbs buffy more strongly and extensively marked with blackish 
brown. Cephalic and median femora distad and tibiae proximad, marked 
with large flecks of blackish brown. Caudal femora suffused with blackish 
brown distad, with genicular areas tawny and dorsal surface showing 
interrupted streaks of blackish-brown. Caudal tibiae with a_ blackish- 
brown proximal annulus, dorsal surface blackish-brown except briefly 
proximad and distad and internal spines and spurs tawny, black tipped. 
™TIn this species the internal spines are proportionately much more 
elongate than in oahuensis.
