complete black band on the basal portion of 
the second tergum in cacuminatus . The female 
ovipositors provide excellent characters for 
separating these species. The ovipositor of 
cacuminatus is shorter and thicker, the rasper 
extends nearer to the base of segment 8, the 
apex of the oviduct and the setae on the 
piercer are farther from the apex of that seg- 
ment, and the plate or section bearing the 
setae is very short compared to that of 
dorsalis. Following are the specific charac- 
teristics of the ovipositor of cacuminatus. In 
undissected specimens the visible portion of 
the ovipositor is about equal in length to the 
fifth tergum. When the ovipositor is fully 
extended (Fig. 14^^), it measures about 3.7 
mm. in length. The piercer is about 1.2 mm. 
by about 0.25 mm. at its widest point. The 
apex of the oviduct is about 0.2 mm. from 
the apex of the piercer. The setae are in- 
conspicuous and are situated about 0.07 mm. 
from the apex of the segment. This distance 
is equal to four times the length of the plate 
bearing the setae or the length of the longest 
setae (Fig. 14^). The inversion membrane is 
about 1.3 mm. long by 0.3 mm. at its 
broadest point. The scales of the rasper extend 
to within 0.32 mm. of the base of the seg- 
ment. The basal segment is about 1.2 mm. 
long, and the spiracles are 0.33 mm. from 
the posterior lateral margins of segment 7. 
Length: Body, 6.0-7. 0 mm.; wings, 5.5- 
6.4 mm. 
TYPE LOCALITY: Brisbane.

This species has been recorded from numer- 
ous localities in Australia. It is chiefly as- 
sociated with the two common species of 
wild tobacco, Solanum verhasci folium Ait. and 
S. auriculatum Ait. 
A large number of specimens are in the 
collection from Atherton Tableland, Queens- 
land, June to Nov., 1949, ex the fruits of 
these two species of Solanum. One specimen 
is at hand, ex Rhipogonum papuanum near 
Atherton, Queensland, Nov., 1949. This is 
the first record of this species infesting fruits 
other than those of solanaceous plants. It is 
possible that the record is an error.

This species is related to D. musae (Tryon) 
and is separated by the presence of a longi- 
tudinal black vitta down the middle of the 
abdomen and by the differences in the female 
ovipositors as illustrated in Figures 15^ and 
21^ and as given under the discussions of the 
ovipositors. D. endiandrae is very similar to 
D. dorsalis Flendel and should be considered 
in this complex of species. In general char- 
acteristics and coloration it is much like 
D. dorsalis and is evidently the nearest thing 
to this species that occurs in Australia. D. 
endiandrae is distinguishable from dorsalis by 
the broad cubital streak and more elongate 
cubital cell in the wing. Comparison of the 
female ovipositors shows close relationship, 
but specific differences are evident. The 
piercer is shorter in endiandrae, the setae are 
farther from the apex of the ovipositor, and 
the scales of the rasper extend nearer to the 
base of segment 8 than they do in dorsalis. 
Except for the female ovipositor, the spe- 
cies has been adequately described by Perkins 
and May, and the following are the diagnostic 
characteristics of both sexes. Head: The front 
is nearly two times longer than wide and has 
two pairs of inferior fronto-orbital bristles. 
The facial spots are oval and somewhat 
pointed on the lower margin. Thorax: Pre- 
dominantly black, especially on the dorsum. 
Mesonotum often with a reddish spot be- 
tween the prescutellar bristles; in some speci- 
mens this extends part way down the dorsum 
as a narrow median vitta. The scutellum has a 
narrow black band at its base. The prescutel- 
lar bristles are the same distance apart as the
