Chrysomelidae of Fiji — Bryant and Gressitt 
57 
longer than sixth; seventh to tenth stouter, 
about as long as sixth; last longer, suddenly 
narrowed before apex. Prothorax nearly as long 
as broad, two-thirds as broad as elytra, some- 
what irregularly rounded at side; disc dis- 
tinctly irregular, with an oblique raised area 
on each side of midline anterior to center, 
preceded anteriorly by an obtuse depression 
and slightly raised area on midline not far 
from apex; disc deeply impressed with longi- 
tudinal elliptical punctures, mostly more 
widely separated transversely than their 
widths; side very coarsely foveate- to reti- 
culate-punctate. Scutellum narrowed, obtuse 
apically, convex. Elytron twice as long as pro- 
thorax, subrectangular, strongly rugose-punc- 
tate, for most part rather irregularly so, with 
two or three extra scutellar rows; disc with 
three distinctly raised areas in a rough line 
somewhat parallel to suture, near base, mid- 
dle, and top of apical declivity, respectively, 
and also many other lesser nodes, ridges, or 
generally irregularly raised interstices. Ventral 
surfaces nearly impunctate. Length 4 mm.; 
breadth 2.2 mm. 
Paratypes: Length 3 . 5-4.2 mm.; breadth 
1.8-2. 2 mm. 
vanua levu: Holotype, female (Bishop 
2438), Nakawanga, alt. 80 m., on Tricho- 
spermum , Oct. 9, 1955, Gressitt. Six paratopo- 
types (one BM), same data, except two on 
Macaranga (probably by chance), Gressitt. 
OVALAU: One, Andubangda, 500 m., July 
15, 1938, Zimmerman. 
VITI LEVU: Two, Belt road, 15-25 km. 
west of Suva, July 22, 29, 1938, Zimmerman; 
two, Lami, Mar. 1951, Krauss. 
HOST: Trichospermun^ calyculatum (Seem.) 
Burret. 
Differs from D. nodosa Bryant in being 
darker, in having the elytron much more 
irregular, with distinct tubercles and strong 
rugosity, and with the pronotum armed with 
a pair of widely spaced low oblique tubercles, 
instead of a pair of fairly close, conical 
tubercles.

Fig. 30 d 
Testaceous; prothorax slightly reddish 
ochraceous; antenna pale ochraceous, becom- 
ing slightly pitchy by last segment; elytral epi- 
pleuron and mesepimeron slightly pitchy red- 
dish. Body clothed above with minute sparse 
golden scale-hairs, and on antenna with longer 
sparse oblique hairs; ventral surfaces nearly 
glabrous. 
Head not quite as broad as prothorax, about 
as broad as deep; frontoclypeus very short, 
partly punctured; occiput finely and closely 
punctured; antennae almost as widely sep- 
arated as eyes. Antenna nearly three-fourths 
as long as body; scape stout, a little longer 
and a little thicker than second segment; 
third to fifth slender, subequal; sixth barely 
shorter than fifth; seventh to tenth subequal, 
moderately stout; last longer, with apex more 
slender and set off. Prothorax nearly as long as 
broad, just over three-fifths as broad as elytra, 
feebly convex at side, fairly even above; disc 
finely punctured, with roughly 25 punctures 
in an approximate median row. Scutellum 
slightly longer than broad, widened at base, 
slightly convex, apically, granulose. Elytron 
more than twice as long as prothorax, sub- 
oblong, narrowed apically; disc in part reg- 
ularly punctured, with eight distinct punc- 
ture-rows above, behind middle, but about 
three extra, partly confused, scutellar rows, 
and four to six rows on lateral declivity; 
punctures mostly about as wide as interspaces 
longitudinally, but more widely separated be- 
tween rows, at least in posterior two-thirds. 
Ventral surfaces nearly impunctate, except for 
bordering grooves of thoracic sternites and 
last abdominal sternite. Hind femur moder- 
ately stout, not reaching apex of abdomen. 
Length 2.4 mm.; breadth 1.25 mm. 
Paratypes: Some vague mottling on part 
of elytron. Length 2. 3-2. 5 mm.; breadth 1.1- 
1.3 mm.
