Trioza flavida n, sp. 
Fig. 25 
Length to tip of folded wings 2.75- 
3.75 mm. 
COLOR: General color yellow. Abdomen 
yellow or greenish yellow. Genal processes 
white. Forewings yellow. 
STRUCTURE: Body surface rugose, almost 
glabrous dorsally. Head large, slightly wider 
than mesoscutum. Vertex impressed discally, 
smoothly rounded to genae. Genal processes 
short, stout, divergent, scarcely over 0.5 as 
long as vertex. Antennae slightly less than 
twice as long as width of head. Eyes of 
moderate size. Postocular areas large, swollen. 
Pronotum vertical. Proepisterna strongly pro- 
duced. Forewings broadly rounded, 2.5 times 
as long as wide, membrane with scattered 
points except along veins, veins setate. Hind 
wings large, set with minute points. Meta- 
tibiae with very small basal serrations, 1 outer 
and 3 inner apical spines. 
Fig. 25. Trioza flavida n. sp. a^ Lateral aspect of male 
cauda; b, lateral aspect of female cauda. 
Male proctiger long, slender, moderately 
swollen caudad. Forceps large, about 0.5 as 
long as proctiger; in lateral view broadly 
clavate; in caudal view slender, arched to 
black tips; in dorsal view tips black, sharp, 
curved caudad. Female genital segment large, 
longer than rest of abdomen, valves large 
basally, slender and styliform apically; dorsal 
valve without conspicuous hump on basal 
portion, with tuft of long setae, apical portion 
straight, slightly swollen at tip, with minute, 
straight setae; ventral valve shorter than 
dorsal, styliform portion upcurved, with 
short stout setae. 
HOLOTYPE, male, allotype, female, many 
male and female paratypes, taken from 
Olearia lacunosa near Balloon Hill, January 10 
and 12. 
HOST PLANT: Ok aria lacunosa Hook. 
This species, taken in company with the 
two preceding, was the most abundant at the 
time of collection. It is quite distinct from 
the other two although it seems to be nearer 
latiforceps than any of the other species known. 
Although a few nymphs were found in 
pseudogalls formed by the curling of the 
edges of young leaves, I am unable to assign 
them to any one of the three species present 
on this host. 
Trioza australis n. sp. 
Fig. 26 
Length to tip of folded wings 3. 5-4.0 mm. 
COLOR: General color cinereous with 
orange to brown markings on vertex, meso- 
dorsum, and legs. Abdomen brown. Tip of 
proctiger and forceps black. Wings hyaline. 
Body more or less completely covered with 
powdery wax. 
structure: Body surface finely rugose and 
with short sparse pubescence. Head narrower 
than mesoscutum. Vertex with strong discal 
foveae, bulging over antennal bases and 
genae anteriorly. Genae produced as slender, 
conical, diverging processes, slightly over 
0.8 as long as vertex. Antennae 1.7 times as 
long as width of head. Eyes large. Postocular
