REVISION OF COEL1D! IN AE 149 



somewhat elongate, occupying about two-thirds 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, venation as in 

 description of genus, veins prominent in $, obscure in <J, appendix well developed; clypeus 

 elongate, very broad anteriorly, narrowed posteriorly, without median longitudinal carina, 

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

 expanded distal ly. 



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

 process very broad basally, becoming curved and narrowly attenuated apically, with numerous 

 striations along inner lateral margin, striations transverse; aedeagus in lateral aspect with 

 dorsal appendage elongate, narrowed throughout, constricted subapically, apex slightly swollen 

 and curved dorsally, without spines or flanges; ventral appendage extremely long, very narrow, 

 tube-like, apex reaching apex of dorsal appendage; gonopore apical; connective Y-shaped; 

 style clawed apically; plate with distal segment somewhat elongate and curved caudodorsally. 



Female seventh sternum with posterior margin produced medially. 



Distribution. Fiji Islands, New Hebrides. 



Specimens examined.

 (BPBM, Honolulu). Tharra nausikaa pallidor Kirkaldy, holotype $, Navua,

The examination of the holotype $ of pallidor and numerous other specimens of 

 the same sex showed sexual dimorphism, thus I have synonymized the name under 

 nausikaa. 



Biology. Unknown. Collection records indicate that the species is prevalent 

 from March through May. 



Remarks. This species is similar to kassiphone Kirkaldy in general habitus 

 and can be separated from that species by the presence of the broadly curved 

 pygofer process with the striations along the inner lateral margin.
