PACIFIC SCIENCE, Vol. XV, January 1961 
cular shape, more broadly rounded anteriorly, 
more numerous submarginal papillae especially 
on abdomen, cephalothoracic area completely 
enclosed by submarginal line and transverse 
moulting suture, 2 papillae on the 6th abdominal 
segment, eye spots distant from submarginal 
line, suture between 7th and 8th abdominal 
segments and pockets very close to anterior 
margin of vasiform orifice. In this latter char- 
acter the species resembles plumensis Dumble- 
ton. 
GENUS Parabemisia Takahashi 
Parabemisia reticulata sp. n. 
Fig. lla-c 
pupal CASE (Fig. lla-c ) : Length 1.0 mm., 
width 0.78 mm. Colour transparent or white, j 
Shape elliptical or subcircular, flat, constricted | 
between thoracic clefts, caudal cleft invaginated. 
Margin with teeth absent but with short nar- 
row ridges immediately mesad of the margin. 
Anterior and posterior marginal setae present. 
Submargin not defined. Segmentation as in fig- 
ure. Thoracic tracheal combs absent, clefts pres- | 
ent. Pore (Fig. lib) inset from margin, opens 
into tracheal fold which is hexagonally reticulate 
for half its length. The reticulated area is some- 
what variable, sometimes longer and expanded 
mesally. Abdomen without setae on 1st segment, 
7th segment shorter than 6th and 8th. Eighth 1 
abdominal setae minute, close to anterior lateral : 
margin of orifice. Vasiform orifice (Fig. 17c) 
longer than wide, subtriangular but rounded 
apically, floor with 8-9 subparallel transverse 
ridges. Operculum sub-semicircular, wider than 
long, less than half as long as orifice, more than 
half length exposed with lateral knob at base 
of exposed part on each side. Caudal setae small, 
midway between apex of orifice and margin. 
Abdominal tracheal cleft and pore similar to 
thoracic, fold reticulate for only a short distance 
cephalad. 
HOLOTYPE: Pupal case on slide mount. De- 
posited in Institut Frangais d’Oceanie, Noumea, 
New Caledonia.
