Differs from R. strigosa (Bryant) in having 
the pronotal puncturation much denser, the 
elytral puncturation somewhat denser, with 
the interspaces narrower and more raised, with 
two instead of one extra scutellar row, and 
with the elytron having fine scales instead of 
being glabrous. 
Genus labasa Bryant 
Labasa Bryant, 1925, Ann. and Mag. Nat. 
Hist. Ser. 9, 15: 592 (type: L. scutellaris 
Bryant; Fiji). 
Rather similar to Rhyparida , but scutellum 
highly transverse and angular; head rugose- 
punctate; pronotum grossly punctured; ely- 
tron subcostate basally. Endemic.

Labasa scutellaris Bryant, 1925, Ann. and Mag. 
Nat. Hist. Ser. 9, 15: 592 (Labasa; type in

Pitchy to blackish or ochraceous; mostly 
dark, with antennal base, parts of legs, and 
some of basal elytral costae ochraceous; ely- 
tral puncture-rows nearly complete, the punc- 
tures weaker posteriorly. Length 5-6 mm.

Genus vitibia Fairmaire 
Vitibia Fairmaire, 1882, Soc. Ent. de France, 
Ann. Ser. 6, 1: 485 (type: V. rufoviolacea 
Fairm.; Fiji). 
Antenna more than one-half as long as 
body, segments subequal except for second. 
Prothorax much narrower than elytra, quad- 
rate, very narrowly margined. Elytron seriate- 
punctate basally, the rows disappearing on 
postmedian portion. Femora unarmed, clav- 
ate; tibiae emarginate preapically. Probably 
some of the following species do not truly 
belong in this genus.
