Australian Fruit Flies — Hardy 
161 
mesonotum chiefly blackish and grayish 
pollinose as in recurrens. Abdomen: First ter- 
gum brown on the basal three-fourths, black 
on the lateral margins. This black margin 
continues posteriorly and runs into the black 
band on the second tergum. Second and third 
terga with moderately broad black bands 
across their bases. The black crossband on 
the third expands laterally, covers all of the 
side margins, and extends posteriorly over 
the lateral margins of terga 4 and 5, narrowing 
rather sharply as it approaches the apex of 
the abdomen. A broad black vitta extends 
down the median part of the abdomen from 
the basal band on the third tergum to the 
apex of the fifth tergum. The fifth segment is 
all rufous except for the extreme lateral mar- 
gins and the median vitta. Ovipositor: The ex- 
posed portion of the ovipositor is about equal 
in length to segments 4 and 5 combined. The 
extended ovipositor is long and slender 
(Fig. \9d) reaching a length of about 6.2 mm. 
The piercer (Fig. Y)h) measures appoximately 
1.8 mm. long by 0.2 mm. wide. The oviduct 
extends to within about 0.28 mm. of the 
apex, and the setae are situated about 0.05 
mm. from the apex of the piercer. The dis- 
tance from the distad pair of setae to the apex 
is equal to about two times the length of the 
plate bearing the setae or to the lengths of the 
longest setae. The inversion membrane is 
about 2.0 mm. long by 0.25 mm. at its widest 
point. The scales of the rasper extend to 
within about 0.9 mm. of the base of the eighth 
segment. The basal segment of the ovipositor 
measures about 1.4 mm. in length. The 
spiracles are situated approximately 0.3 mm. 
from the base of the segment. 
Length: Body, 5.4-6. 2 mm.; wings, 5.0- 
5.7 mm. 
TYPE LOCALITY: Caims, bred from Strychnos 
bancroftiana. No type designated. 
Type series in the Queensland Museum. 
Thirteen specimens are in the Krauss col- 
lection from: Babinda, Queensland, ex 
Strychnos sp., Nov., 1949, and Iron Range, 
Queensland, ex Strychnos sp.(.^) prob. ban- 
croftiana, Aug., 1949.

Strumeta bilineata Perkins and May 1949. 
Univ. of Queensland, Dept. Biol. 2(14): 
7-8. This name is preoccupied in Dacus by 
D. bilineatusWAker I860. Linn. Soc. Lond., 
Proc. 4: 150. 
No specimens were present in the Krauss 
collection, but specimens for study have been 
received from Mr. Alan May. A brief descrip- 
tion and figures of the ovipositor are given 
here in order to compare this with the re- 
lated species that are discussed. 
D. mayi is related to D. breviaculeus and dif- 
fers from it in the ways discussed under that 
species. The ovipositor is comparatively short

full length; b, apex of ovipositor.
