segment. Subcircular dorsal surface, body top- 
shaped. Margin barely crenulated, submarginal 
pores broad. Thoracic tracheal fold visible on 
ventral surface as asperities. Thoracic tracheal 
combs (Fig. 11 b) present as small marginal 
teeth with 2 or 3 obscure teeth mesally. Thoracic 
and abdominal segmentation indistinct. Legs 
tapering, then widened distally. Vasiform orifice 
(Fig. 11c) subcordate with a small cell apically. 
Eighth abdominal setae short, fine, level with an- 
terior margin of orifice. Operculum subcordate, 
filling orifice. Lingula included, parallel-sided, 
apex rounded. Caudal setae short, fine, bases not 
as far apart as bases of 8th abdominal setae. 
These larvae occurred in pits on the upper 
surface of the leaves of Grevillea gillivrayi on 
Mont Dore (coll. L.J.D.). The disc of the dor- 
sum is covered with a shieldlike raised white 
wax plate, except for the orifice and the caudal 
area (Fig. lid). They are considered to be 
those of reflexa because of the brown pigmenta- 
tion and the pit-making habit on the upper 
surface of the leaf. 
PUPAL CASE (Fig. 11 e—g ) : Length 0.60 mm., 
width 0.58 mm. Colour dark brown. Shape cir- 
cular, flat dorsally but convex ventrally where 
it fits into a pit on the leaf. Apparent margin 
straight. Margin reflexed ventrally, distant about 
0.1 mm. from apparent margin except posteriorly 
where it arises from near the anterior end of 
the abdominal tracheal pore, crenulated or with 
11-12 short rounded teeth in 0.1 mm. A sub- 
marginal line between the apparent margin and 
the margin, nearer to the latter. Area between 
margin and apparent margin radially striate. 
Setae absent, sutures and segmentation as in 
Figure 11^. Minute scattered simple pores on 
body. Thoracic tracheal folds (Fig. 11/) pres- 
ent, beset with minute dots. Thoracic pore 
flask-shaped, invaginated, and with thick sides, 
the inner walls covered with short transverse 
projections, outer margin toothed. Abdomen, 
first abdominal segment short, 7th apparently
