impunctate 
marginipennis marginipennis 
Discal punctures of elytron much 
smaller than interspaces; prothorax 
feebly grooved at side; frons distinctly 
punctate. . . marginipennis lauensis 
1. Coenobius geniostomae Gressitt, n. sp. 
Female: Testaceous, largely transluscent cr 
transparent, somewhat ochraceous on center 
of pronotum and middle of metasternum; 
elytron blackish on base and suture and ob- 
liquely on scutellar portion, and pitchy on 
outer margin; antenna pale on scape, dull 
ochraceous on next four segments, pitchy on 
remainder. 
Head flat in front, round in outline, sparsely 
punctured on frons. Antenna two- thirds as 
long as body, fairly slender; scape fully as 
long as next two segments together; third 
slightly longer than second, fourth, and fifth; 
following longer and stouter, subequal. Pro- 
thorax five-eighths as long as broad, broad 
anteriorly, shiny, sparsely punctured, ob- 
liquely grooved at side; basal margin pro- 
duced and emarginate opposite scutellum. 
Scutellum slender, narrowed apically. Elytron 
slightly narrowed between postbasal and pre- 
apical portions, distinctly punctured in reg- 
ular rows, the punctures in most cases much 
narrower than interpunctural rows. Ventral 
surfaces closely punctured on side of thorax 
and second and following abdominal ster- 
nites; first sternite nearly as large as remainder 
of abdomen. First hind tarsal segment as long 
as next two combined. Length 2.5 mm.; 
breadth 1.5 mm. 
vanua levu: Holotype, female (Bishop 
2403), between Navakuru and Nakawanga, 
300 m., on Geniostoma vitiense , Oct. 7, 1955, 
Gressitt; paratype, female, same data. 
HOST: Geniostoma vitiense Gilg and Benedict. 
Differs from C. marginipennis Bryant in 
being stouter, with the prothorax shorter and 
broader anteriorly, the antenna partly dark- 
ened, and the elytron punctured but not 
grooved. The paratype lacks the black on 
scutellar portion of the elytral disc. 
2. Coenobius marginipennis 
marginipennis Bryant 
Coenobius marginipennis Bryant, 1938, Roy. 
Ent. Soc. London, Proc. B 7(11): 249. 
(Vanua Levu; type in Brit. Mus.) 
Pale fulvous; elytron narrowly margined 
with fuscous; antenna with five basal seg- 
ments fulvous and six apical segments tinged 
with fuscous. 
Head impunctate; eyes meeting above. 
Antenna with six apical segments broader; 
scape nearly as long as second to fourth com- 
bined. Prothorax shiny, transversely grooved 
near anterior margin; side with an oblique 
groove; base produced into a lobe at middle. 
Scutellum impunctate, narrowly elongate. Ely- 
tron finely punctate-striate, interstices at side 
slightly convex. Pygidium closely punctured 
and clothed with very fine golden pubescence. 
First abdominal segment very long; second 
and third short and equal; last about equal to 
second and third combined. Length 2.5 mm. 
viti levu: Thuvu, Lautoka (after Bryant); 
nineteen, Lami Quarry, near Suva, Feb. 1951, 
Krauss; ten, Raki Raki, Lami, Lautoka, and 
Ndeumba, Jan. and Mar. 1955, Krauss. 
vanua levu: Type from Lambasa. Sixteen, 
eight, east of Lambasa, on Glochidion corda- 
tum , Oct. 6, 1955, Gressitt; four, Nakawanga, 
on Glochidion ramiflorum , Oct. 8, 1955, 
Gressitt. 
taveuni: After Bryant. 
HOSTS: Glochidion cordatum (Muell. Arg.)

3. Coenobius marginipennis lauensis 
Gressitt, n. subsp. 
Fig. 1 
Male: Pale ochraceous, slightly duller on 
distal half of antenna, narrowly pitchy on 
basal margin of prothorax. Legs and ventral 
surfaces sparingly clothed with short sub- 
erect pale hairs.
