 {T. C. Maa) (BPBM, Honolulu). 



Paratypes. New Guinea: allotype $, Mt Plora, 6° 45' S. 146 ° E., 1900 m, 

 12.vi.1966 (/. L. Gressitt) (BPBM, Honolulu). Moluccas: Ambon, 1 9- (F. Muir) 

 (BPBM, Honolulu). 



Biology. Unknown. Collection dates are June and July. 



Remarks. This species has a unique pygofer process which is short and hooked 

 apically, and which separates it from other species of Tharra. 



Tharra forissa sp. n. 



(Text-figs 214-218) 



Length: $ 7*30 mm, $ unknown. 



General colour ochraceous with several very small spots scattered on elytra. Crown 

 ochraceous; eyes fuscous; pronotum and scutellum ochraceous; elytra ochraceous with 

 numerous ivory spots in cells; clypeus ochraceous with an ivory transverse band anteriorly. 



Head considerably 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, disk elevated above eyes ; 

 ocelli large, situated anteriolaterally; eyes moderate size, occupying a little over half of entire 

 dorsal area of head; pronotum large, median length greater than median length of crown; 

 scutellum large, median length about equal to median length of pronotum; elytra long and 

 narrow, veins prominent, appendix very well developed, venation as in description of genus; 

 clypeus long, broad anteriorly, narrowed posteriorly, without median longitudinal carina, 

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

 constricted medially. 



Male pygofer in lateral aspect with long, narrow process arising caudoventrally, process 

 nearly equidistant throughout, sharply pointed apically, with large, lateral subapical flange 

 on inner lateral margin; aedeagus in lateral aspect with dorsal appendage broad at basal half, 

 narrowed slightly at apical half ; dorsal appendage with a pair of long spines arising medially 

 on subdorsal margin, projecting basally, and a long, narrow, lateral flange medially; ventral 

 appendage long, tube-like, extending beyond apex of dorsal appendage; gonopore apical; 

 connective Y-shaped; style hooked apically; plate with terminal segment elongate, lateral 

 margins expanded subapically.

Holotype <$, New Guinea: Papua, Mt Dayman, Maneau Range, 2230 m, N. 

 slope No. 4, 17.V.1953 (Geoffrey M. Tate) (AMNH, New York). 



Paratype. New Guinea: Mt Missim, 2400 m, 1 <$, 22-30. iv.1968 (/. L. Gressitt, 

 R. C. A. Rice & J. Sedlacek), in author's collection. 



Biology. Unknown. 



Remarks. This species is similar in general habitus to villosa but can be separated 

 from that species by the presence of a large, subapical, lateral flange on the pygofer 

 process.
