Fig. 15c 
Female; Bronzy black, or pitchy to testa- 
ceous; head reddish anteriorly, bronzy black 
behind; antenna reddish tinged with pitchy; 
prothorax bronzy blackish, but bronzy testa- 
ceous on anterior and posterior borders and 
along median line; scutellum pitchy; elytron 
blackish bronzy, testaceous along basal half 
of suture and on apex; ventral surfaces black- 
ish, becoming brownish towards apex of ab- 
domen; legs testaceous. 
Head with a few distinct punctures an- 
teriorly, finely and sparsely punctured on 
occiput. Antenna three-fourths as long as 
body; first two segments swollen, first one- 
half again as long as second; third to sixth 
slender, subequal, each about as long as scape; 
seventh to last stouter and longer. Prothorax 
four-fifths as long as broad, not distinctly 
margined laterally, moderately punctured, the 
punctures mostly one-third or less as large as 
spaces between them. Scutellum narrowed and 
rounded behind. Elytron moderately punc- 
tured in regular rows, the punctures mostly 
smaller than interspaces, and disappearing at 
beginning of apical third. Ventral surfaces 
feebly punctured. Length 2.8 mm.; breadth 
1.6 mm. 
vanua levu: Holotype, female (Bishop 
2417), Nakawanga, Oct. 8, 1955, Gressitt; 
allotype, male, and one paratype, female, same 
data. Another female, same data, entirely 
green, somewhat questionably this species. 
The coloration varies from almost entirely 
blackish green, except for antenna and legs, 
to bronzy ochraceous with sides cf prothorax 
and elytron, and suture, darker. 
Differs from V. obscura in being darker and 
more metallic, and in having the pronotum 
more finely punctured, and the elytron with 
punctures lacking posteriorly.
