to orifice, and distant from it. Vasiform orifice 
(Fig. 13c) subcordate, not notched posteriorly 
but contoured posteriorly by a semicircular line. 
Operculum subcordate, filling orifice. Lingula 
short, rounded apically. Caudal setae minute, 
bases as wide apart as those of the 8th abdominal 
setae. Two lateral discal pores on each side op- 
posite segments 5 and 7. Dorsal disc, especially 
between abdominal ridge and submargin, beset 
with subcircular pustules. Abdominal tracheal 
fold faintly indicated, finely stippled from ori- 
fice half way to margin. Abdominal tracheal 
comb present with 4 to 6 teeth which are longer 
than wide. 
HOLOTYPE: Pupal case on slide mount. De- 
posited in I ns ti tut Frangais d’Oceanie, Noumea, 
New Caledonia. 
PARATYPES : In authors collection.

FOOD PLANT: Leucopogon sp. 
This species shows some affinities with Aleuro - 
paradoxus Q. & B. and Pentaleyrodes Takahashi.

PUPAL CASE (Fig. 1 4a-c) : Length 0.89 mm., 
width 0.57 mm. Colour dark but paler than 
sinuata. Shape elliptical, margin less sinuate 
than sinuata. Margin (Fig. 1 4b) with 9 proc- 
esses on each side less prominent than in sinuata. 
Between the processes on the submargin are 14 
or 15 pores in a linear series. Pores tending 
to be longer than wide. Disc pores as in figure. 
Laterad on or near the submargin is a row of 
minute paired pores. Mesad of these on the ab- 
domen at mid-length is a pair of larger dark- 
bordered pores and a similar pore laterad on 
the mesothorax. The abdominal ridge is nar- 
row. Bases of the 8th abdominal setae slightly 
anterior to orifice and wider apart than the 
orifice width. Vasiform orifice (Fig. 14 c) sub- 
cordate, similar to that of sinuata. The bases of 
the caudal setae are slightly nearer to the apex 
of the orifice than the margin and about the 
same distance apart as the orifice width. Ab- 
dominal tracheal fold absent, comb of 8 to 9 
teeth whose rounded apices are level with mar- 
gin.
