146 M. W. NIELSON 



Paratypes. Fiji: allotype $, same data as holotype (BPBM, Honolulu); Labasa, 

 3 cJ, 2 $, xii.1921 (R. Veitch) (BPBM, Honolulu); 4 <?, same data as holotype, in 

 author's collection. 



Biology. Unknown. 



Remarks. This species is similar to testacea in general habitus, but can be 

 separated from it by the distinctive pygofer process and the male plate on which the 

 distal segment is curved caudodorsally. 



Tharra transversa sp. n. 



(Text-figs 397-401) 



Length: <§ 5-30-5-90 mm, 9- 6-10-6-70 mm. 



General colour ochraceous; sexual dimorphism apparent. Crown light to deep ochraceous; 

 eyes light to deep fuscous; pronotum ochraceous; scutellum ochraceous with deep fuscous 

 markings, especially in §; elytra ochraceous throughout in $ except for narrow, uneven fuscous 

 band subapically, deep, broad, fuscous vittae 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 converging basally; ocelli medium size, situated anteriorly; 

 eyes moderate size, somewhat elongate, occupying a little over half of entire dorsal area of 

 head; pronotum large, median length about equal to 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, very broad anteriorly, narrowed posteriorly, lateral margins somewhat 

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

 narrowly rugulose along anterior margin; clypellus with lateral margins expanded apically. 



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

 process very broad basally, becoming somewhat attenuated throughout, sharply pointed 

 apically with transverse striations medially; aedeagus in lateral aspect with dorsal appendage 

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

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

 extending slightly beyond apex of dorsal appendage; gonopore apical; connective Y-shaped; 

 style broadly hooked; plate with distal segment somewhat elongate, curved caudodorsally. 



Female seventh sternum with posterior margin produced medially. 



Specimens examined. 



Holotype <J, Fiji: Viti Levu, Suva, v.1951 (N. L. H. Krauss) (BPBM, Honolulu). 



Paratypes. Fiji: allotype $, Lami, Viti Levu, iii.1951 (N. L. H. Krauss) 

 (BPBM, Honolulu) ; 9 <J, 17 $, same data as allotype (BPBM, Honolulu) ; 1 <J, 1 $, 

 same data as allotype (BMNH, London); 1^,1$, same data as allotype (LTF, 

 Turku) ; 2 <$, 2 $, same data as allotype, in author's collection. 



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

 from February to April. 



Remarks. This species is similar to nausikaa in male genital characteristics, 

 but can be separated from that species by the larger size and the shorter and 

 broader crown.
