other material: Slide mounts of geni- 
talia and wings and unmounted duplicate 
material in Maskell collection. Unmounted

adults from Asplenium lucidum , Ruby Bay, 
Nelson, Jan. 1952, in the author’s collection. 
There are no undoubtedly endemic species 
of Trialeurodes known in Australia or New 
Zealand and since asplenii occurs on Asplenium 
and other ferns it could well have been intro- 
duced on ornamental ferns and not be native 
to New Zealand.

pupal case: (Fig. 3). Length 0.75-0.10 
mm., width 0.5-0.75 mm. Derm thin and 
colourless except for the papillae. Shape ellip- 
tical. Case raised off leaf on vertical palisade 
of white wax. Margin (Fig. 4 a) crenulated, 
about 12 crenulations in 0.1 mm. Thoracic 
tracheal pore area (Fig. Ah') marked by narrow- 
ing and depth of 3-10 crenulations. Com- 
monly 75-110 submarginal papillae in a 
single row; 1-9 pairs may be larger than the 
others but these may be absent. Usually four 
pairs of subdorsal papillae but these may be 
absent. When present one pair is cephalic, 
one pair mesothoracic and one pair on each 
of the third and fourth abdominal segments. 
Setae; one pair cephalic, one pair first ab- 
dominal, one pair 8th abdominal often very 
long, and one pair caudal usually long. Vasi-
