Fig. 1. Coenobius marginipennis lauensis Gressitt, n. 
subsp. 
Head moderately punctured; eyes touching 
above. Antenna three-fourths as long as body, 
sixth and following segments thickened. Pro- 
thorax shiny, feebly punctured, feebly grooved 
at side. Scutellum subelliptical, about three 
times as long as broad. Elytron with ten reg- 
ular rows of punctures which are mostly much 
smaller than spaces between them, longitud- 
inally and transversely. Ventral surfaces in part 
punctured, largely impunctate on metaster- 
num and first abdominal sternite. Pygidium 
closely punctured. Length 2.4 mm.; breadth 
1.35 mm. 
Female: Antenna three-fifths as long as 
body; last six segments moderately thickened 
and pitchy. Length 2.5 mm.; breadth 1.6 mm. 
lau: Holotype, male (Bishop 2385), Naiau 
I., Fiji, Sept. 12, 1924, E. FI. Bryan, Jr.; allo- 
type , female (Bishop), by seashore near Loma 
Loma, Vanua Mbalavu I., Aug. 7, 1938, Zim- 
merman. 
K and avu : A third specimen, male, from 
Kaivala, Apr. 29, 1941, Krauss, is also referred 
to this subspecies. 
Differs from C. marginipennis marginipennis 
Bryant in being larger, entirely testaceous 
except for antenna, and in having the frons 
punctured, the pronotum less distinctly 
grooved at side, and the elytral punctures 
mostly much smaller than spaces between 
them.

Fig. 2a, h 
Male: Reddish brown to dark pitchy, 
largely pitchy above; ventral surfaces slightly 
paler; base of antenna, front of head, and legs 
testaceous; fourth and following antennal 
segments gradually darked, last nearly black; 
pygidium brown. Antenna, legs, and ventral 
surfaces sparingly clothed with short oblique 
pale hairs. 
Head finely and irregularly punctured, 
somewhat raised on frons; eyes touching 
above. Antenna three-fourths as long as body, 
last five segments moderately thickened; scape 
hardly as long as second and third segments 
combined; second to fourth subequal in 
length, second more swollen. Prothorax just 
over two-thirds long as broad, much wider 
near base than at apex; lateral margin flat- 
tened, broadly expanded basally; apical collar 
moderately developed; median basal process
