norum metallic greenish black, bordered with 
pitchy; elytron metallic purplish. 
Head carinate medially and grooved on each 
side between antennal insertions, the grooves 
continuous with grooves bordering eyes; 
occiput smooth and impunctate. Antenna 
slender, fully two-thirds as long as body; 
first two segments not very stout, scape half 
again as long as second; third to sixth slender, 
increasing slightly in length; last longest. 
Prothorax transverse, suboblong, slightly con- 
vex on lateral and basal margins; disc strongly 
convex, impunctate, deeply grooved sub- 
basally. Scutellum rounded-triangular. Elytron 
long, somewhat gradually narrowed posteri- 
orly, strongly swollen on disc behind base, 
unevenly punctured: punctures in rows, but 
postbasal swelling and posterior half of disc 
practically impunctate, and punctures strong- 
est in depression behind postbasal swelling. 
Ventral surfaces finely and irregularly punc- 
tured. Middle tarsus with first segment nearly 
as long as next two combined, and narrower 
than third; hind tibia shallowly, and some- 
what obliquely grooved posteriorly. Length 
2.4 mm.; breadth 1.15 mm. 
viti levu: Holotype, male (Bishop 2459), 
Limi Quarry, near Suva, May 1951, Krauss; 
allotopotype, female, and two male para- 
topotypes, same data. 
Differs from C. caeruleoviolacea Bryant, of 
New Hebrides, in being smaller, in having 
the prothorax greenish, the elytron less bluish 
and much less even and less regularly punc- 
tured. Named in honour of N. L. H. Krauss, 
of Honolulu, the collector of a number of 
species described in this work. 
118. Crepidodera rotunda Gressitt, n. sp. 
Female: Shiny black above, dark pitchy 
reddish beneath and on hind femur; antenna 
testaceous; legs reddish. 
Head stout, smooth and shiny above. An- 
tenna slightly over half as long as body, fairly 
slender; first two segments moderately thick- 
ened, scape a little longer than second; third 
about as long as second; fourth and fifth 
successively longer; sixth a little shorter than 
fifth and seventh; remainder subequal. Pro- 
thorax about three-fifths as long as broad, 
slightly convex in outline of each border; 
front corner oblique; disc subevenly convex, 
smooth, minutely punctulate, feebly grooved 
subbasally. Scutellum triangular, finely punc- 
tured. Elytron broad, even, without a post- 
basal swelling or depression; moderately, and 
regularly, punctured on basal three-fourths, 
the punctures smaller than interspaces, and 
with minute punctulation on general surface. 
Abdomen finely punctured. Fore and middle 
tarsus with first three segments subequal; 
hind tibia with posterior face flat or shallowly 
depressed for entire length, finely toothed on 
outer edge. Length 2.25 mm.; breadth 1.3 
mm. 
viti levu: Holotype, female (Bishop 2460), 
Lami Quarry, near Suva, May 1951, Krauss; 
paratopotype, female (elytra lacking), same 
data. 
Differs from C. fijiensis Csiki ( nigra Bryant) , 
in being much broader, less than twice as long 
as broad, with the pronotum very shallowly 
grooved subbasally, and the elytron even, 
without a postbasal swelling followed by a 
depression. 
Genus psylliodes Latreille 
Psylliodes Latreille, 1829, IN Cuvier, Regne 
Anim. 2 ed., 5: 154; Maulik, 1926, Fauna 
of India, Chrysom. and Haltic.: 124 (type: 
Chrysomela chrysocephala L.). 
Head smooth or carinate medially; antenna 
10-segmented; prothorax transverse, feebly 
rounded at side; elytron broader basally than 
prothorax, as a rule regularly punctate-striate; 
scutellar rows of punctures generally long; 
hind tibia broadened distally and channelled 
above, the channel bordered with spinules, 
with tarsal insertion considerably before apex; 
first hind tarsal segment long and slender; 
claws simple.
