(Scale in mm.) 
PARATYPES: In author’s collection. 
TYPE LOCALITY; New Caledonia, Montagne 
des Sources, 3,000 ft., coll. L.J.D. 
FOOD PLANT: Hibbertia sp. 
Similar to A. calophylli Kotinsky from Fiji 
but differing in the form of the marginal teeth.

Fig. 3 a-c 
pupal CASE (Fig. 3 a-c): Length 1.0 mm., 
width 0.72 mm. (holotype) but reaching 1.4 
mm. long. Colour black. Shape broadly elliptical, 
rounded anteriorly and posteriorly. Rather flat

but with median ridge and 2 thoracic lateral 
ridges. Wax fringe white about one-third body 
width. There is a submarginal line of wax, an 
inverted U-shaped wax line more or less con- 
touring the adult head and thorax, and 3 or 6 
transverse lines on the abdomen. Inside the mar- 
ginal line of wax there are narrow radial striae 
of wax and the disc is powdered with wax. Mar- 
gin (Fig. 3 b) strongly toothed, teeth rounded, 
7 teeth in 0.1 mm. Submargin not defined from 
dorsal disc, radially striate, striae same width 
as teeth; with a number of minute simple pores, 
3 cephalic, 2 thoracic, 2 mid-length on abdomen. 
Thoracic and abdominal tracheal folds, pores, 
combs, and clefts absent. Eye spots present, sub- 
triangular. Cephalic and thoracic areas without 
setae, pores as in figure. Abdomen, segment 1 
with 1 pair paramedian pores, segments 2-6 
limited laterally and with paramedian pores. Be- 
tween segments 3 and 6, 4 lateral rays on each 
side. Seta bases on 8th abdominal segment on 
orifice rim about mid-length of orifice. Caudal 
seta bases close together, nearer margin than 
orifice. 
Vasiform orifice (Fig. 3 c) subcordate, 0.06 
mm. wide, 0.065 mm. long, internally toothed. 
Operculum subcordate, filling orifice 0.05 mm. 
long. Lingula parallel-sided, apex rounded. 
HOLOTYPE: Pupal case on slide mount. De- 
posited in Institut Francis d’Oteanie, Noumea, 
New Caledonia.

FOOD PLANT: Leucopogon sp. On upper sur- j 
face of leaf. 
This species comes nearest the genus Aleuro- 
canthus and is similar to dissimilis Q. & B. in 
the absence of long spines and to T - signatus 
Mask., serratus Q. & B., and spinosus Kuwana 
in the presence of lateral rays on the abdomen. 
Aleurocanthus spinithorax sp. n.

LARVA. Second instar (Fig. 4a): Length 
0.4 mm., width 0.27 mm. Colour pale laterally, 
brown medially. Margin with short broad trun- 
cate teeth. Cephalic area with 2 pairs of short 
conical spines anterior to cephalic hairlike setae
