disc and the transverse and median moulting 
sutures are also elevated. Submargin radially 
striate 0.25 mm. wide, on outer half with 
radial rows of 4—5 minute circular poriferous 
papillae mesad of alternate teeth, intervening 
areas darker, inner half with radial rows of less 
well-defined subcircular nonporiferous papillae. 
Submarginal line on cephalothorax continuous 
with transverse moulting suture. Cephalic area 
with eye spots oval, long axis 0.03 mm. long, 
oblique, enclosed by submarginal line, without 
setae or evident pores. Thoracic area, without 
setae or evident pores. Tracheal folds not vis- 
ible dorsally, cleft present but closed, pore 
(Fig. Ih) minute, subcircular, minutely toothed, 
inset from margin. Cephalothorax with scattered 
irregular minute pores. Abdomen. Submarginal 
line of abdomen ending level with orifice, the 
two halves joined by a semicircular raised line 
anterior to orifice, from the junction on each 
side a short raised line runs mesocaudally so 
that the orifice is enclosed except caudally. Ab- 
domen, segments 1-6 subequal in length, with- 
out setae but with transverse row of minute 
pores, seventh segment half as long. Vasiform 
orifice (Fig. 7c) semicircular, 0.03 mm. long, 
0.035 mm. wide. Operculum semicircular, 0.02 
mm. long, 0.03 mm. wide, filling orifice. Lingula 
not visible. Eighth abdominal setae represented 
by pores, level with anterior margin of orifice 
and distant from it.

This species would run to Dialeurodes sub- 
genus Gigaleyrodes Q. & B. in Quaintance & 
Baker’s key, and is reminiscent of D.( G.) cerifera 
Q. & B.

LARVA. Second instar: Length 0.30 mm., 
width 0.28 mm. Elliptical. Colourless. Similar 
to 3rd instar but tubercles absent and marginal 
teeth more distinct.
