Chrysomelidae of Fiji — Bryant and Gressitt 
83 
Fig. 42. Manobia levicollis Gressitt, n. sp., type. 
Differs from M. metallica Bryant in being 
smaller, dark reddish instead of metallic green, 
with the scape much less than twice as long 
as second antennal segment, and the pro- 
notum finely punctured basally. 
125. Manobia obtusicollis Gressitt, n. sp. 
Reddish brown, slightly pitchy on sides of 
metasternum and abdomen; antenna and legs 
pale ochraceous. 
Head with frons fairly large, smooth; occi- 
put impunctate. Antenna not quite reaching 
to middle of elytron; scape one-half again as 
long as second segment; third nearly as long 
as scape, subequal in length to following, 
which gradually increase in thickness; last 
longer. Prothorax three-fourths as long as 
broad, slightly broadened from base to apex, 
feebly convex at side, distinctly obtuse bas- 
ally; disc subevenly convex, finely punctured, 
slightly depressed and somewhat more 
strongly punctured near base. Scutellum small, 
nearly hidden by pronotum. Elytron broadest 
anterior to middle, considerably attenuated 
apically; disc strongly swollen near base, de- 
pressed behind swelling, deeply punctured in 
fairly regular rows, the punctures stronger in 
postbasal depression and becoming very fine 
apically, the interspaces distinctly raised, par- 
ticularly at side. Ventral surfaces slightly punc- 
tured. Hind femur not very stout; first hind 
tarsal segment nearly as long as remaining 
combined. Length 2.3 mm.; breadth 1.15 mm. 
viti levu: Holotype (Bishop 2462), Nan- 
darivatu, 1100 rn., Sept. 6, 1938, Zimmerman. 
Two additional specimens, one of nearly same 
data as type, and the other from Tholo-i-suva, 
June 28, 1924, Bryan, are only tentatively 
associated with this species. 
Differs from M. costata Bryant, in being 
reddish instead of partly greenish, in having 
the antenna paler, and the pronotum less 
strongly punctured. 
126. Manobia producticollis Gressitt, n. sp. 
Male: Dark pitchy black above, more red- 
dish pitchy beneath and on appendages; sec- 
ond to fourth antennal segments more reddish 
than remainder. 
Head fairly long, produced at mouth parts, 
smooth on occiput. Antenna barely more than 
one-half as long as body; first two, and last 
five, segments thicker than others; scape a 
little longer than second segment; third small- 
er than second; fourth a little longer than 
third, subequal to fifth and following in 
length. Prothorax two-thirds as long as broad, 
broadened from base to apex, with side fairly 
straight; basal margin sinuate, strongly 
rounded and produced at middle; disc 
strongly convex, finely punctured, with 
a sinuate, more strongly punctured, subbasal 
depression. Scutellum small, subrounded be- 
hind. Elytron broadest anterior to middle; disc 
with a distinct postbasal swelling followed by 
a depression, distinctly punctured throughout 
in regular rows, the punctures slightly larger 
in postbasal depression and slightly finer near
