Length: £ 5-10-5-40 mm, § 5-70-6-00 mm. 



General colour light to deep ochraceous. Crown deep ochraceous sometimes with light 

 orange to rufous longitudinal marking below ocelli; pronotum light ochraceous to deep 

 ochraceous; eyes deep ochraceous; scutellum light to deep ochraceous; elytra ochraceous 

 with a small light fuscous spot midway between the commissural line and the apex of the 

 elytra; clypeus and clypellus ochraceous. 



Head narrower than pronotum; crown long and broad, produced distally beyond anterior 

 margin of eyes, distal length about one-third entire median length, striate radially, lateral 

 margins nearly parallel, disk elevated considerably above level of eyes; ocelli small, situated 

 anteriorly; eyes moderate size, somewhat globular, occupying about half entire dorsal area of 

 head; pronotum short, median length less than median length of crown, surface finely knobbed; 

 scutellum large, median length greater than median length of pronotum; elytra elongate, 

 veins concolorous and slightly obscured, appendix well developed, venation as in description 

 of genus; clypeus elongate, broad anteriorly, narrowed posteriorly, lateral margins constricted 

 medially near antennal sockets, without median longitudinal carina, surface finely granulose, 

 narrowly rugulose along anterior margin; clypellus with lateral margins nearly parallel, 

 slightly expanded apically. 



Male pygofer in lateral aspect with broad, curved process arising from caudoventral margin, 

 process with lateral margins nearly equidistant but somewhat sinuate basally, apex slightly 

 curved and abruptly pointed with numerous oblique striations, apex twisted; aedeagus in 

 lateral aspect with dorsal appendage narrowed throughout except for subapical constriction, 

 apex broadly expanded, without spines or flanges; ventral appendage rather broad, tube-like, 

 expanded apically and extending considerably beyond apex of dorsal appendage; gonopore 

 apical; style clawed apically; plate with distal segment elongate, dorsal margins expanded. 



Female seventh sternum with posterior margin produced medially. 



Distribution. Tonga Islands, Loyalty Islands (Lifou), New Hebrides.

Examination of the type-material of lutea Montrouzier and pallida Osborn 

 reveals that these two species are synonymous; lutea is the oldest and therefore 

 the valid name. Although Montrouzier labelled his specimen 'lutea' in the genus
