size, occupying less than half of the entire dorsal area of the head; pronotum short, median 

 length less than median length of crown; scutellum large, median length greater than median 

 length of pronotum; elytra elongate, veins prominent, venation as in generic description, 

 appendix well developed; clypeus long, very broad anteriorly, narrowed distally, slightly 

 concave in lateral aspect, with short, obscure median longitudinal carina anteriorly, surface 

 rugulose along anterior margin, finely granulose below; clypellus with lateral margin narrow 

 basally, slightly divergent apically. 



Female seventh sternum with posterior margin produced medially. No males were available

Distribution. Fiji Islands. 



Specimens examined. 



Muirella oxyomma Kirkaldy, holotype <$, Fiji: Viti Levu, Rewa (F. Mwir) 

 (BPBM, Honolulu). 



Fiji: Rewa, 4 $, hi. 1906 (F. Muir); Navua, 2 9- "■ 1906 (F. Muir); 1 $, Lami, Viti Levu, 

 iv. 1951 (N. L. H. Krauss), 2 $, Tholo-1-Suva, Viti Levu, iv. 1951 (A r . L. H. Krauss). 



Biology. Unknown. Collections were made from February to April. 



Remarks. Since no males were available for illustration of the genitalia, 

 characters of the female head can be used to separate the same sex of other long- 

 headed species of the genus. Tharra oxyomma is most closely related to frontalis 

 and can be separated from the latter by the concaved clypeus, longer crown and 

 the presence of but obscured clypeal carina.
