REVISION OF COELIDIINAE 181 



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

 process very broad basally, becoming attenuated throughout and slightly pointed apically; 

 aedeagus in lateral aspect with dorsal appendage broad at basal three-fourths, narrowly 

 constricted subapically, somewhat bulbous apically, without spines or flanges; ventral appendage 

 short, somewhat tube-like, expanded apically and extending beyond apex of dorsal appendage; 

 gonopore apical; connective Y-shaped; style broadly hooked apically; plate with distal segment 

 somewhat elongate, bulbous subapically. 



Female seventh sternum with posterior margin produced medially. 



Distribution. Samoa Islands, Moluccas (Sula I.). 



Specimens examined. 



Coelidia testacea Walker, holotype <$, Moluccas: Sula I. (Wallace) (BMNH, 

 London). Jassoidula niuensis Osborn, holotype $, allotype q\ Samoa: Niue, 

 Savage Island, 6.viii.i9i8 (Kellers) (BPBM, Honolulu). Jassoidula niuensis Osborn, 

 paratypes, 5 <$ and 4 $, same data as holotype (USNM, Washington). 



Samoa: Niue, Savage Island, 6^, 1 $, 6.viii.iQi8 (H. C. Kellers). 



Dissection and examination of the male genitalia of the holotype of testacea 

 Walker and allotype of niuensis Osborn showed that the two species were identical. 

 Proper association of the sexes of the holotype female and allotype male were made. 



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

 in August. 



Remarks. This species is very similar in general habitus to lenta but can be 

 separated from that species by the presence of the curved, tapered pygofer process. 



Tharra nigroides sp. n. 



(Text-figs 489-493) 



Length: $ 3-90 mm, § unknown. 



General colour testaceous. Crown ochraceous; eyes rufofuscous; pronotum, scutellum and 

 elytra testaceous; clypeus and clypellus testaceous. 



Head slightly narrower than pronotum; crown short and narrow, produced slightly beyond 

 anterior margin of eyes, distal length about one-fourth entire median length, striate radially, 

 lateral margins converging basally, disk elevated slightly above level of eyes; ocelli small, 

 situated anteriorly; eyes large, somewhat globular, occupying over two-thirds entire dorsal 

 area of head ; pronotum short, median length less than median length of crown, surface finely 

 knobbed; scutellum small, median length about equal to median length of pronotum; elytra 

 elongate, veins somewhat obscured, appendix well developed, venation as in description of 

 genus; clypeus elongate, broad anteriorly, narrowed posteriorly, without median longitudinal 

 carina, surface granulose at apical half, rugulose at basal half; clypellus with lateral margins 

 divergent apically. 



Male pygofer in lateral aspect with long, curved twisted process arising from near middle of 

 caudal margin, process with lateral margins somewhat broad basally, becoming attenuated 

 and constricted subapically, then bulbous subapically and narrowly pointed apically with a 

 few striations subapically; aedeagus in lateral aspect with dorsal appendage broad at basal 

 half, narrowly attenuated and constricted subapically, slightly bulbous apically, curved 

 caudodorsally, without spines or flanges; ventral appendage narrow, tube-like, long, extending
