apically. The second tergum has a subbasal 
brown to slightly blackish crossband and a 
yellow- white apex. In some specimens the 
median black vitta is indistinct on terga 3 
and 4. 
Length: Body, 5. 5-5. 8 mm.; wings, 4.8- 
5.0 mm. 
FEMALE. The hind tibiae often have a 
blackish tinge on their apical halves. The 
narrowed portion of the discal cell is one and 
one-fifth times longer than the portion be- 
yond the apex of the cell. Ovipositor: Short and 
inconspicuous; the exposed portion is not as 
long as the fifth abdominal segment. The 
extended ovipositor is very short and com- 
paratively broad (Fig. lb), the over-all length 
is about 3.3 mm. The piercer measures ap- 
proximately 1.08 mm. by 0.24 mm. The ovi- 
duct extends to within 0.19 mm. of the apex 
of the piercer and the setae are about 0.06 mm^ 
from the apex. The setae and the plate bearing 
them are rather short, the length of the plate, 
or the length of the longest setae, being equal 
to about one-fourth the distance from the 
bases of the distal pair of setae to the apex of 
the piercer (Fig. Ic). The inversion membrane 
is about 1.2 mm. long by 0.3 mm. wide. The 
scales of the rasper are broad and blunt and 
extend to within 0.3 mm. of the base of the 
eighth segment. The basal segment of the 
ovipositor is about 1.0 mm. long by 1.0 mm. 
wide, the spiracles are situated approximately 
0.22 mm. from the posterior lateral margins 
of the segment. 
Holotype male, allotype female, and eight 
paratypes (three males and five females) : Lake 
Barrine, Queensland, ex Litsea (J), Nov., 1949- 
Type and allotype deposited in the United 
States National Museum. Two paratypes in 
the Bishop Museum; two in the Territorial 
Board of Agriculture and Forestry collection; 
two in the Hawaiian Sugar Planters’ Associa- 
tion collection; and two at the University of 
Hawaii.

mens of jarvisi with paratypes of australis. 
This species is readily distinguished from 
all known members of this subgenus by the 
continuous yellow markings connecting the 
humeral and notopleural calli. Only the more 
important characteristics are given in the 
following description. 
MALE. Front very slightly expanded on the 
lower half, nearly two times longer than wide. 
The vertical bristles are brownish-yellow to 
yellow, the frontals are brown to black. Two 
pairs of inferior fronto-orbital bristles are 
present. The facial spots are nearly circular 
and their height is equal to about one-fourth 
the length of the face. The third antennal seg- 
ment is just slightly longer than the face and 
is appoximately three times longer than wide. 
Thorax: Chiefly reddish, mesonotum largely 
gray pollinose. The gray pollen is dissected 
by one median and two sublateral shining 
lines extending the full length of the dorsum. 
Wings: First two costal cells hyaline with no 
microtrichia except in the apex of the second 
cell. The costal band is rather narrow and does 
not extend below vein R3 except at its base 
and extreme apex. The band expands slightly 
in the wing apex and extends nearly halfway 
between the ends of vein R4+5 and M1+2. 
The cubital streak is broad, filling all of the 
base of cell M4 and extending nearly to the 
top margin of the r-m crossvein. The nar- 
rowed portion of the cubital cell is about 
three times longer than the distance from the 
apex of the cell to the wing margin. Abdomen: | 
Chiefly yellow to rufous. First tergum all ' 
yellowish, sometimes faintly brownish tinged. 
Second tergum with a subbasal brown to
