REVISION OF COELIDIINAE 103 



at basal two-thirds, narrowly attenuated at apical one-third; dorsal appendage with a pair of 

 prominent lateral spines projecting basally, curved laterally at apical half, ventral margin 

 with short spines subbasally, projecting caudally; ventral appendage broad basally, constricted 

 medially, expanded apically to a triangulate or subquadrate lobe, apex exceeding apex of 

 dorsal appendage; gonopore apical; connective Y-shaped; style clawed apically; plate with 

 distal segment elongate, expanded medially along dorsal margin. 

 Female seventh sternum with posterior margin projecting medially. 



Specimens examined. 



Holotype $, Borneo: Sandakan {Baker) (USNM, Washington). 



Paratypes. Borneo: allotype $, Paring, near Ranau, 23. i. 1958 (T. C. Maa) 

 (BPBM, Honolulu); 3 £, same data as holotype (USNM, Washington); 1 $, same 

 data as holotype (BMNH, London) ; 1 <£, same data as holotype, in author's collection. 



Biology. Unknown. 



Remarks. This species is similar to pectoid.es and can be distinguished by the 

 pair of lateral spines situated medially on the dorsal appendage of the aedeagus. 



Tharra lineata sp. n. 



(Text-figs 274-278) 



Length: £ 5-60 mm, § 6- 10— 6-30 mm. 



General colour deep ochraceotis, suffused with fuscous. Crown deep fuscous suffused with 

 ochraceous below; eyes rufofuscous; pronotum and scutellum deep ochraceous; elytra deep 

 ochraceous basally suffused with deep fuscous subapically; clypeus and clypellus suffused with 

 fuscous and ochraceous. 



Head distinctly 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 on either side of middle, lateral margins slightly convergent basally, 

 disk elevated considerably above level of eyes; ocelli small, situated anteriorly; eyes moderate 

 size, somewhat elongate, 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, very broad 

 anteriorly, narrowed posteriorly, distinctly excised along middle next to antennal sockets, 

 without median longitudinal carina, surface finely granulose, narrowly rugulose along 

 anteriolateral margins; clypellus with lateral margins divergent apically. 



Male pygofer in lateral aspect with long, very narrow, curved process, almost needle-like, 

 process slightly broader basally, becoming very narrowly attenuated apically; aedeagus in 

 lateral aspect with dorsal appendage broad at basal three-fourths, becoming narrowly attenuated 

 subapically, constricted subapically, and bulbous apically, curved dorsally at apex; dorsal 

 appendage with a pair of lateral spines situated medially and a pair of flanges on the dorsal 

 margin subbasally, with very small, sharp dentate processes along middle of ventral margin; 

 ventral appendage long, tube-like, apex expanded and produced distally beyond apex of 

 dorsal appendage; gonopore apical; connective Y-shaped; style broadly curved apically, not 

 quite clawed; plate with distal segment elongate, dorsal margin expanded medially, apex 

 narrowed. 



Female seventh sternum with posterior margin produced slightly at middle. 



Specimens examined. 



Holotype <3\ Borneo: north, Ranau, 22-25.ii.1959 (T. C. Maa) (BPBM, Honolulu).
