Fig. 2. Dacus {Afrodacus) jarvisi (Tryon): a, female 
ovipositor, full length; b, ovipositor, apex, 
black band; the apical half is whitish-yellow. 
The third tergum has a narrow black band 
across its base and a narrow black line run- 
ning longitudinally down the middle. The 
black median vitta continues on over terga 
4 and 5. 
Length: Body, 6. 5-7.0 mm.; wings, 6.0- 
6.5 mm. 
FEMALE. The narrowed portion of cell Cu 
is slightly more than one and one-half times 
longer than the distance from its apex to the 
wing margin. Ovipositor: The exposed portion 
is about equal in length to the combined 
lengths of segments 4 and 5. The extended 
ovipositor (Fig. 2d) measures about 5.0 mm. 
in length. The piercer (Fig. 2b) is approxi- 
mately 1.7 mm. long by 0.22 mm. wide. The 
oviduct extends to within 0.23 mm. of the 
apex of the piercer. The setae are about 0.05 
mm. from the apex, this distance being equal 
to about two times the length of the plate 
bearing the setae or to two times the lengths 
of the longest setae. The inversion membrane 
is about 2.0 mm. in length by 0.3 mm. in 
width. The scales of the rasper extend to 
within 0.6 mm. of the base of segment 8. 
The basal segment of the ovipositor is about 
1.4 mm. long by 1.2 mm. wide. The spiracles 
are located 0.28 mm. from the posterior- 
lateral margins of the segment. 
TYPE locality: Stanthorpe, South Queens- 
land; reared from pear and quince. 
Type in Queensland Museum. 
Large numbers of specimens were in the 
Krauss collection from the following: Cairns, 
Queensland, ex papaya, Eugenia cormiflora, 
Semecarpus australiensis, guava, Careya aus- 
tralis, and Terminalis catappa, Dec., 1949, to 
Apr., 1950. 
Dacus (Afrodacus) jarvisi var. halteratus 
Hendel 
Dacus {Chaetodacus) australis var. halter ata 
Hendel 1928. Ent. Mitteil., 17(5): 342-343. 
This variety was not present in the Krauss 
collection but because so much material has 
been studied from the Cairns area its status 
should be discussed here. The variety hal- 
teratus was described from a single female 
specimen taken at Cairns. Dr. Hering (in cor- 
respondence) said that he had studied the 
type of halter atd' years ago and that it ’'is 
only an individual form” oi jarvisi. It is prob- 
able that this should not be considered a 
variety but should be treated as a synonym. 
Of the large number of specimens of jarvisi 
which have been studied from the Cairns area 
none has been seen which fits the description 
of halteratus. Hendel’s specimen was probably 
discolored. According to the original de- 
scription and Dr. Hering, the variety differs
