behind. Elytron narrow, subparallel in basal 
two-thirds; disc punctured in about nine rows, 
the punctures unequal in size, interspaces 
from one to three times as wide as punctures, 
which disappear in apical third. Ventral sur- 
faces and appendages with sparse suberect 
pale hairs. Length 2.3 mm.; breadth 1.1 mm. 
Paratypes: Some slightly reddish, or 
slightly darkened along suture. Length 2.25- 
2.5 mm.; breadth 1.1-1.28 mm. 
viti levu: Holotype, male (Bishop 2414), 
Tholo-i-suva (Colo-i-suva), June 21, 1924, 
E. H. Bryan, Jr. Four paratypes: Nandarivatu, 
1100 m., Sept. 3, Navai-Nasonga trail, west 
slope, 800 m., Sept. 12, 1938, Zimmerman, 
and Mt. Victoria, 1100 m., Sept. 10, 1938, 
Kondo. 
Differs from V. vitiensis (Bryant) in having 
the pronotum more narrowed anteriorly more 
heavily punctured, the elytron punctured far- 
ther posteriorly, and the aedeagus being more 
gradually narrowed and acuminate apically. 
38. Vitibia ruflabris Bryant, n. sp. 
Fig. 14£, c 
Shining black; lab rum, base of antenna, 
and legs more or less rufous. Prothorax 
strongly punctured; elytron more finely punc- 
tate-striate. 
Head and labrum more or less rufous, a few 
very strong punctures between bases of an- 
tennae; basal portion of head impunctate. 
Antenna extending to middle of elytron; basal 
segments rufous; five apical segments fus- 
cous, each with basal portion fulvous. Pro- 
thorax shining black strongly punctured; side 
rounded. Scutellum black, nitid, triangular, im- 
punctate. Elytron shining black, wider than 
base of prothorax, sides parallel and rounded 
to the apex, more finely punctate-striate, be- 
coming almost impunctate towards apex. 
Legs more or less rufous, tarsi paler, middle 
and posterior tibiae emarginate near apex. 
Underside with the ventral segments of the 
abdomen fulvous and impunctate. Length 
3 mm. 
viti levu: Holotype (Bishop 2415), Nan- 
darivatu, 600 m., Sept. 1, 1938, Zimmerman. 
Three paratypes: Nandarivatu, Sept. 5, Zim- 
merman; Nandarivatu, Oct. 18, 1937, Valen- 
tine; ridge west of Nandarivatu, 800 m., 
Sept. 9, 1938, Zimmerman. 
Somewhat similar to R. strigosa (Bryant), 
but with no trace of pubescence, and the 
puncturation of the prothorax much stronger, 
and the punctate-striae of the elytron much 
finer. 
39- Vitibia obscura obscura Gressitt, n. sp. 
Fig. 15^, b 
Dull testaceous to bronzy pitchy, in part 
paler; head bronzy pitchy, paler on frons; 
antenna pitchy brown, testaceous on first four 
segments; pronotum bronzy pitchy, some- 
what paler basally and on anterior margin; 
elytron dull brown, paler behind humerus, 
darker on margin and blackish along suture; 
ventral surfaces reddish brown, darker on 
metasternum; legs testaceous. Antenna, legs, 
and distal portion of abdomen moderately 
clothed with oblique goldish hairs. 
Head with a few deep punctures on frons 
and vertex, and a few medially on anterior 
portion of occiput; eye rounded oval. An- 
tenna three-fourths as long as body, slender; 
first six segments subequal in length except 
second a little shorter; seventh and following 
segments longer; last appendiculate. Pro- 
thorax very slightly broader than long, nearly 
as broad at apex as at base, moderately and 
evenly rounded at side; disc rather heavily 
punctured, the punctures mostly a little 
smaller than spaces between them. Scutellum 
convex, tapering. Elytron subparallel-sided, 
tapering from end of third fifth; disc with 
rows of deep punctures which are mostly 
nearly as large as interspaces; discal rows 
disappearing on apical declivity. Ventral sur- 
faces feebly punctured. Length 2.2 mm.; 
breadth 1 mm. 
Paratypes: Length 2. 1-2.3 mm.; breadth 
1-1.2 mm.
