mg somewhat oblique longitudinal lines on 
central portion, mostly about as broad as 
interspaces on basal half, much finer pos- 
teriorly. Ventral surfaces deeply punctured on 
metasternum, more finely punctured on re- 
mainder. Length 2.7 mm.; breadth 1.5 mm. 
viti levu: Holotype (Bishop 2426), Nan- 
darivatu, 1100 m., beating shrubbery, Sept. 
10, 1938, Zimmerman. Four paratypes (Bish- 
op, BM): Nandarivatu, Sept. 6-10, Mt. Ko- 
rcmbamba, 400 m., Aug. 1, and Tholo-i-suva, 
150 m., July 25, 1938, Zimmerman. 
Differs from S. leveri (Bryant) in being 
longer, more bronzy, with more golden pu- 
bescence, and in closer pronotal puncturation.

Fig. 20c 
Metallic green, with a slightly golden tinge, 
above; purplish pitchy beneath; antenna testa- 
ceous, becoming slightly pitchy beyond mid- 
dle; legs testaceous. Dorsum distinctly 
clothed with posteriorly arched silvery white 
hairs, in some lights appearing slightly golden. 
Head four-sevenths as broad as prothorax, 
rather broad and flat between antennal inser- 
tions and eyes, sparsely punctured, a little 
more coarsely punctured towards postocciput. 
Antenna three-fourths as long as body; first 
two and last five segments moderately thick- 
ened; scape distinctly longer than second 
segment; third about as long as second, 
slightly shorter than fourth; fourth to sixth 
subequal; seventh and following slightly 
longer. Prothorax four-sevenths as long as 
broad, as broad as elytral base, distinctly nar- 
rowed and declivitous at side, anteriorly; 
rounded at side, but hardly wider at any point 
than at base; disc deeply impressed with mod- 
erate-sized punctures which are mostly about 
as large as spaces between them. Scutellum 
narrowed and obtuse posteriorly, distinctly 
punctured basally. Elytron more than twice as 
long as prothorax, subevenly rounded in ex- 
ternal outline, widest a little anterior to mid- 
dle; disc deeply and distinctly punctured, the 
punctures only vaguely arranged in rows on

basal half, where most of them are about as 
large as interspaces, and much sparser, finer, 
and less regular on posterior half. Ventral 
surfaces with only a few punctures on meta- 
sternum, and some vague wrinkling or minute 
punctures on abdominal sternites. Length 1.85 
mm.; breadth 1.05 mm.
