Australian Fruit Flies — FIardy 
147 
ground color (well differentiated from the 
cream markings of the thorax), and is covered 
with gray pruinosity except for a shining 
vitta down the middle extending the full 
length of the thorax. The bristles are reddish- 
brown to black. The halteres are pale yellow. 
Legs: Chiefly yellow. The hind tibiae are 
tinged with brown to black. Wings: Chiefly 
hyaline, with a distinct but narrow costal band 
and a broad cubital streak. The first two 
costal cells are hyaline to very faintly yellow- 
ish and are devoid of microtrichia except in 
the apical part of the second costal cell. The 
costal band does not extend noticeably below 
vein R3 except in the apical part of cell R3. 
The band extends a short distance into cell 
R5 at its apex. The r-m crossvein is straight, 
without a noticeable curve. The cubital streak 
fills all of the basal part of cell M4 nearly to 
the top margin of the m-cu crossvein. The 
narrowed portion of the cubital cell is two 
times longer than the distance from the apex 
of the cell to the wing margin. Abdomen: 
Predominantly yellow with dark brown to 
black on the sides. The first tergum is largely 
brown with a narrow yellow-red apex. The 
second tergum has a narrow yellow-red band 
across the base, followed by a brown to 
black band, and by a broad yellowish band 
which occupies the apical half. The third 
tergum has a black band across the base and 
the sides are broadly black. The median 
portion has a very faint, brownish vitta ex- 
tending over it. In some specimens this is 
very distinct and extends over segment 4. 
The fourth tergum is broadly yellow in the 
central portion (except as noted above) and 
blackish on the sides. The fifth tergum is 
largely yellow except for narrow brownish 
lateral margins. 
Length: Body, 6.0 mm.; wings, 5.2 mm. 
FEMALE. The cubital streak fades out about 
halfway along vein Cui and 1st A. The nar- 
rowed portion of the cubital cell is one and 
one-third times longer than the distance from 
the apex of the cell to the wing margin. 
Ovipositor: Extremely short, scarcely notice- 
able in in situ specimens. From a dorsal view 
the visible part of the ovipositor is usually 
less than half as long as the fifth abdominal 
segment. When the ovipositor is fully ex- 
tended (Fig. 12^) it measures approximately 
2.5 mm. in length. The piercer is about 0.75 
mm. long by 0.12 mm. wide. Four pairs of 
setae are conspicuous (Fig. 12c), the two 
distad pairs are about twice as well developed 
as the basal pair. The setae are situated about 
0.055 mm. from the apex of the piercer, 
measured from the bases of the apical pair. 
This is slightly more than three times the 
length of the plate bearing the setae and four 
times longer than the longest setae. The 
piercer is just slightly more than six times 
longer than its greatest width and is gradually 
tapered beyond the apex of the oviduct 
(Fig. 12c). The oviduct extends to within 
0.13 mm. from the tip of the piercer. The 
inversion membrane is about 0.83 mm. long 
by 0.2 mm. wide. The scales of the rasper 
are large, conspicuous, diamond-shaped, and 
extend to within 0.2 mm. of the base of the 
eighth segment. The basal segment is about 
0.9 mm. long, measured on a mid-line, by 
0.75 mm., measured across its hind margin. 
The spiracles are 0.13 mm. from the base of 
the segment, measured on the lateral margins. 
Length: Approximately the same as in the 
male. 
Holotype male, allotype female, and 12 
paratypes (6 males and 6 females) : near 
Atherton, Queensland, Dec., 1949, ex Glochi- 
dion harveyanum. Two male paratypes: Cairns, 
Queensland, Aug., 1949, same host as type. 
Type, allotype, and two paratypes de- 
posited in the United States National 
Museum. Three paratypes are in the Bishop 
Museum collection, Honolulu, T. H.; three 
are in the Board of Agriculture and Forestry 
collection, Honolulu, T. H.; three are at the 
Hawaiian Sugar Planters’ Association; and 
three are in the University of Hawaii collec- 
tion. 
Three specimens, one female and two 
males, which apparently belong here, were
