PACIFIC SCIENCE, Vol. VIII, April, 1954 
The median portion of the front is discolored 
with brown. The face has an oval black spot 
in each antennal furrow. The third antennal 
segment is brown and is approximately four 
times as long as wide. Thorax: Chiefly black 
with the postsutural yellow vittae as described 
above and with the front margins of the meso- 
notum reddish around the humeri. The meso- 
notum is rather densely covered with gray 
pollen. The scutellum is entirely yellow ex- 
cept for a narrow band of black at its base. 
The mesopleural stripe is just slightly wider 
than the notopleural callus. Legs: The femora 
are predominantly yellow; the apical third to 
two fifths are discolored with brown. The 
tibiae are all brownish. Wings: As in dorsalis. 
We find no differences in the venation or the 
wing coloration. Abdomen: Very similar to 
that of dorsalis with broad black basal bands 
on terga one to three and with a median 
longitudinal black vitta extending from three 
over five. The sides are not extensively black- 
ened as in cognatus. Ovipositor: In situ the basal 
portion of the ovipositor is not quite 0.75 as 
long as the fifth abdominal segment. The 
ovipositor is very short; when fully extended 
it measures approximately 2.92 mm. The basal 
segment is about 1. 1 mm. long by I.O mm. 
wide at its widest point. The spiracles are 
situated about O.I mm. from the base of the 
segment, measured to the anterior lateral mar- 
gins. The inversion membrane measures 0.91 
mm. by 0.26 mm. The rasper extends to with- 
in 0.15 mm. of the base of the segment. The 
piercer tapers gradually to the apex; it is rather 
broad and blunt at the tip. The piercer meas- 
ures approximately 0.91 mm. by 0 18 mm. 
The oviduct opens about 0.21 mm. from the 
apex. The preapical setae are about 0.05 mm. 
from the apex. There are two moderately long 
and two tiny setae present (Fig, 9^). 
Length: Body, 6.0 mm.; wings, 5.5 mm. 
MALE. As in the female, except for the 
sexual characters. 
Holotype female, allotype male, and four 
paratypes, one male and three females, from 
Makiling, Philippine Islands, Feb. 21, 1921, 
ex fallen fruit of Sideroxylon macranthuni 
Merr. (F. X. Williams). 
The holotype and allotype are being de- 
posited in the U. S. National Museum, the 
paratypes are in the Hawaiian Sugar Planters’ 
Association, Bernice P, Bishop Museum, and 
the University of Hawaii collections.

Dacus alhistrigatus de Meijere, 1911, Tijdschr. 
V. Ent. 54: 377, pi. 20, fig. 33. 
This species is very distinctive and is dis- 
tinguished from all other known Strumeta by 
the well- developed transverse band through 
the middle of the wing and the very oblique 
r-m crossvein (Fig. 10^), by the lack of a dis- 
tinct costal band, by the large triangular black 
mark on the scutellum, and by the broad 
gray vittae extending longitudinally down the 
middle of the mesonotum (Fig. 10^). The 
postsutural yellow vittae are strongly nar- 
rowed posteriorly. 
From de Meijere’s original description and 
figure it is obvious that Hendel’s synonymy 
is correct. Perkins (1938: 128) says that the 
costal band (in de Meijere’s drawing) is too 
dark and conspicuous to be frauenfeldi. We 
believe it is just an error on the artist’s part; 
the shading along the costal margin should 
represent faint yellowish fumosity. The de- 
scriptions by de Meijere and Perkins {loc. cit.) 
are adequate except for the details of the 
ovipositor. 
Ovipositor: The basal portion {in situ) is 
about equal to or slightly shorter than the 
fifth abdominal segment. The extended ovi- 
positor (Fig. 10c) measures about 3.7 mm. 
The piercer is 1.2 mm. long by 0.15 mm. 
wide at its widest point. The oviduct opens 
about 0.17 mm. from the apex of the piercer. 
The preapical setae (Fig. lOd) are situated 
about 0.05 mm. from the apex. The inversion
