row of 7 or 8 tubercles on each side, the pos- 
terior members tending to become continuous 
with the ridges bounding the anal furrow. These 
abdominal tubercles and those on the thorax 
outline the adult body. Seventh segment nar- 
rower than 6 and 8. Eighth segment with a pair 
of minute setae level with anterior margin of 
vasiform orifice, bases as wide apart as orifice 
width. Vasiform orifice (Fig. 5 c) subtriangular, 
long, acutely pointed, with 2 or 3 oblique ridges 
on each side of apical half. Operculum semi- 
circular, not more than half the length of orifice. 
Lingula long, exposed, spatulate, pointed. Ridges 
of anal furrow contouring the orifice where 
the tubercles are somewhat pectinated, smooth 
tubercles between orifice and cauda. Caudal setae 
minute, on ends of furrow ridges near margin. 
HOLOTYPE: Pupal case on slide mount. De- 
posited in Institut Frangais d’Oceanie, Noumea, 
New Caledonia. 
PARATYPES: In author’s collection. 
TYPE LOCALITY: New Caledonia, Montagne 
des Sources, coll. L.J.D. 
FOOD PLANT: Cordyline sp. 
The tuberculation suggests Aster obemisia Tre- 
han but the thoracic and abdominal tracheal 
folds and combs are absent. The species re- 
sembles Bemisia shinanoensis Kuwana but lacks 
setae on the abdomen.
