PACIFIC SCIENCE, Vol. XV, January 1961 
pores with thick walls of external diameter 0.045 
mm. Thoracic area with 1 pair of similar pores 
immediately anterior to thoracic folds which are 
not sculptured and end in a comb of about 5 
minute teeth. Abdomen with three pairs of large 
simple pores near margin, one opposite the 
transverse moulting suture, one slightly anterior 
to the orifice, and one caudad of the orifice. Ab- 
dominal tracheal fold and comb not evident. 
First abdominal segment with one pair of short 
setae. Eighth abdominal setae present longer 
than orifice, bases level with anterior margin of 
orifice. One short seta cephalad of each large 
caudal pore. Caudal setae caudad of these pores. 
Vasiform orifice (Fig. 6b) subcordate, 0.06 mm. 
wide, 0.045 mm. long, no teeth on margin. 
Operculum nearly filling orifice, 0.04 mm. wide, 
0.035 mm. long. Lingula included, constricted 
near base, 0.02 mm. long, 0.015 mm. wide, sub- 
truncate apically. 
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, Dothio 
River Bridge, coll. F. Cohic, 17/6/53. 
FOOD PLANT: Undetermined. 
This species is closely related to D. decem- 
punctata Q. & B. but differs in that the thoracic 
fold is not between the first and second pores, 
in the spearhead shape of the marginal setae and 
in having only one seta anterior to each caudal 
pore. It differs from D. viburni Takahashi in 
having only one seta anterior to each caudal 
pore and in the form of the marginal setae. It 
belongs to the subgenus Dialeuropora Q. & B.

PUPAL CASE (Fig. 7 a-c): Length 1.25 mm., 
width 1.2 mm. Colour black. Shape subcircular, 
faintly constricted across thoracic folds but in- 
vaginated caudally at abdominal tracheal pore. 
The marginal fringe, of white wax rods half as 
wide as body, may split in stellate fashion into 
10 rays. Margin with rounded teeth, 10 teeth 
in 0.1 mm., anterior and posterior marginal 
setae present. The submarginal line is higher 
in elevation than the margin and the dorsal
