two-thirds as long as broad, strongly convex, 
deeply and rather closely punctured, all four 
corners prominent. Scutellum rounded-trian- 
gular, nearly smooth. Elytron deeply, some- 
what closely, and irregularly punctured, the 
punctures slightly finer apically; suddenly 
narrowed, and declivitous, apically. Ventral 
surfaces in part finely punctured. Hind femur 
nearly reaching to abdominal apex; hind tibia 
shallowly concave behind; first hind tarsal 
segment nearly as long as remainder com- 
bined. Length 1.8 mm.; breadth 1.2 mm. 
Female: Antenna one-half as long as body. 
Length 2.9 mm.; breadth 1.6 mm. 
viti levu: Holotype, female (Bishop 2455), 
Lami Quarry, near Suva, May 1951, Krauss; 
allotype, female, Tholo-i-suva, Jan. 1955, 
Krauss; 9 paratopotypes, May 1951, Krauss; 
one paratype, Navai, Sept. 1950, Krauss; one, 
Tholo-i-suva, Apr. 1951, Krauss. 
Differs from A. greenwoodi Bryant in being 
much larger, greenish instead of black, with 
the pronotum closely punctured, and the hind 
femur reddish instead of black.

Female: Body shiny black to pitchy black 
above, dark reddish pitchy beneath; slightly 
pitchy on elytral disc; head pitchy anteriorly; 
eye pinkish silvery; antenna and fore and 
middle legs testaceous, in part tinged with 
pitchy; hind legs reddish castaneous. 
Body narrow. Head largely impunctate, with 
a subtransverse groove behind a pair of swell- 
ings immediately behind antennal insertions. 
Antenna two-thirds as long as body, distinctly 
thickened distally; scape moderately stout, a 
little longer than second segment; third longer 
than second, and more slender; fourth to 
tenth subequal to third; last longer and much 
stouter. Prothorax three-fifths as long as 
broad, rounded at side, corners not very 
prominent, finely and sparsely punctured. 
Scutellum short, rounded-triangular. Elytron

punctured throughout, the punctures mostly 
about as large as interspaces. First hind tarsal 
segment nearly as long as remaining com- 
bined. Length 1.6 mm.; breadth 0.95 mm. 
vanua levu: Holotype, female (Bishop 
2456), between Navakuru and Nakawanga, 
400 m., Oct. 7, 1955, Gressitt. 
Differs from A. greenwoodi Bryant in being 
smaller, more parallel-sided, with the hind 
femur reddish, the pronotum much more 
finely punctured, and without a longitudinal 
impression, and with the elytron a little more 
finely punctured. Named for Senetiki, govern- 
ment agricultural assistant, who accompanied 
me on the walk across Vanua Levu.
