Chrysomelidae of Fiji — BRYANT and GRESSITT 
35 
distal portions of fore femur pitchy. Abdo- 
men, legs, and antenna with sparse suberect 
pale hairs. 
Head nearly six-sevenths as broad as pro- 
thorax, about as wide as deep, moderately 
punctured in center; occiput finely grooved 
and hardly punctured. Antenna slender, four- 
fifths as long as body; scape two-thirds again 
as long as second segment; third a little longer 
than second, distinctly shorter than fourth; 
fifth equal to fourth, slightly longer than 
sixth; seventh to last longer, stouter, sub- 
equal. Prothorax slightly longer than broad, 
nearly two-thirds as broad as elytra, evenly 
rounded at side, widest at middle, barely nar- 
rower at apex than at base; disc convex, 
subevenly punctured, the punctures mostly 
about one-third as large as interspaces in 
center, and larger and closer at side. Scutellum 
small, rounded at side and obtuse apically. 
Elytron slightly more than twice as long as 
prothorax, slightly broadened behind middle, 
where it is somewhat inflated at top of lateral 
declivity; disc convex, somewhat regularly 
punctured in nine rows at middle, the punc- 
tures mostly about one-half as wide as inter- 
spaces, and suddenly becoming minute at end 
of second third. Abdomen feebly rugulose- 
punctate. Length 2.5 mm.; breadth 1.13 mm. 
Female: Length 2.4 mm.; breadth 1.34 
mm. 
viti LEVU: Holotype, male (Bishop 2419), 
Nandarivatu, 1100 m., Sept. 10, 1938, Zim- 
merman; allotype, female, Lami Quarry, near 
Suva, May 1951, Krauss. Three paratypes: 
Nandarivatu, Sept. 10. 1938, Zimmerman, 
Lami Quarry, May 1951 and Mar. 1955, 
Krauss. 
Differs from V. obscura submetallica Gressitt 
in being almost uniformly metallic greenish 
above, in having the prothorax longer, sym- 
metrical antero-posteriorly, and the aedeagus 
with terminal orifice proportionately shorter 
in relation to distance to bend, and apex a 
little more acuminate.

Fig. 17 a, b 
Female: Pale ochraceous, marked with 
pitchy brown; head testaceous; antenna testa- 
ceous on first three segments, remainder pit- 
chy with bases reddish; prothorax pale 
ochraceous with median line broadly pitchy, 
the line slightly broadened at middle; elytron 
pitchy reddish brown with a slight bronzy 
tinge, pale ochraceous on extreme base, testa- 
ceous on humeral ridge from behind humerus 
nearly to middle; ventral surfaces testaceous, 
duller at side of abdomen; legs testaceous. 
Legs and ventral surfaces sparingly clothed 
with short oblique goldish hairs; denser hairs 
on antenna. 
Head sparsely and distinctly punctured on 
frons and vertex, slightly grooved on occiput; 
frons as deep as wide between antennal inser- 
tions. Antenna fully three-fourths as long as 
body, slender; first six segments subequal in 
length except second and third slightly short- 
er; seventh and following longer and slightly
