Syn. n. 

 Tharra ogygia Kirkaldy; Linnavuori, 19606 : 27. 

 Tharra ogygia Kirkaldy; Metcalf, 1964 : 25. 



Length: <J 5-00-5-40 mm, $ 5-90-6-00 mm. 



General colour ochraceous to deep fuscous. Crown, pronotum and scutellum light ochraceous 

 to deep fuscous; eyes light rufous to rufofuscous; elytra ochraceous to deep fuscous, colour 

 generally deeper in $; clypeus and clypellus ochraceous. 



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

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

 depressed medially, lateral margins nearly parallel or slightly convergent basally, disk elevated 

 above level of eyes; ocelli small, situated anteriorly; eyes moderate size, semiglobular, occupying 

 a little over 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 prominent, appendix well developed, venation as in 

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

 excised along middle near antennal sockets, without median longitudinal carina, surface 

 finely granulose, rugulose along anterior margin; clypellus with lateral margins expanded 

 apically. 



Male pygofer in lateral aspect with large, broad, twisted process arising from caudoventral 

 margin, process with lateral margin broad basally, becoming slightly sinuate subapically and 

 twisted or abruptly curved subapically, apex pointed, sometimes with longitudinal striations 

 along entire shaft of process; aedeagus in lateral aspect with dorsal appendage somewhat 

 narrowed throughout, slightly constricted subapically and expanded apically, without spines 

 or flanges; ventral appendage short, somewhat tube-like, expanded apically and slightly 

 exceeding apex of dorsal appendage; gonopore apical; connective Y-shaped; style broadly 

 clawed apically; plate with distal segment elongate, dorsal margin expanded medially. 



Female seventh sternum with posterior margin produced medially. 



This species is highly variable in form and colour. 



Distribution. Fiji Islands.

Examination and comparisons of the types of ogygia and atriceps reveal that 

 these two species are identical, ogygia being the valid name through priority. 

 The illustration of Tharra ogygia by Linnavuori (i960 : 26, fig. 9) is not that species. 



Biology. Unknown.
