elytron closely punctured, but less strongly so 
than on prothorax, slightly depressed behind 
shoulder, broadest behind middle, rounded 
at apex; abdominal sternites slightly pubescent; 
first hind tarsal segment longer than rest. 
Length 2. 2-2. 5 mm.; breadth 1-1.2 mm. 
VANUA LEVU: Lambasa (type loc.). Naka- 
wanga, 45 m., on Inocarpus , Oct. 1955, Gres- 
sitt; 15 specimens. 
HOST: Inocarpus fagiferus (Parkinson) Fos- 
berg. 
This species is apparently variable in color. 
All of the ten females in the above series are 
entirely black above; two of the males are 
entirely black above; one male has only the 
humerus pale, as in the type series; and two 
males have two large pale spots on the ely- 
tron. This species was observed to jump.
