A. R. Wallace, B. M. 1858-42.” He found 
two species present in this series, two males 
and two females of the species which we take 
to be emittens, and one which appears to be 
a Daciis {Strumeta) related to dorsalis Hendel. 
Walker mentioned the extensive wing infus- 
cation in his description and referred to a 
number of varieties designated by Greek let- 
ters, his "Var. e male” lacked these markings. 
Perkins (1939: 29) says the species possesses 
short but distinct black humeral bristles. 
A female specimen at hand apparently be- 
longs here, although the wing maculadons 
differ in some respects from the typical form. 
On our specimen the infuscation over the m 
crossvein does not extend along vein M3+4, 
and the r-m crossvein is slightly infuscated 
(Fig. 24^). The costal cells are pale yellow, 
and the apical half of the second costal cell 
is covered with microtrichia; this character 
has not been mentioned in previous descrip- 
tions. Our specimen does not possess the 
black humeral bristles mentioned by Perkins

{loc. cit.) ; a moderately well-developed yellow- 
red humeral is present on the right side, this 
is absent (or broken off.^) on the left. Our 
specimen also has no black bands over the ab- 
dominal segments, but the basal portion of the 
third tergum is brown. A brown longitudinal 
vitta is present over only about three fourths 
of the fifth tergum. Walker’s description of 
the abdomen was rather vague, i.e., ”a black 
middle band, behind which there is a slight 
longitudinal black line.” Hendel, in his de- 
scription of chrysotoxus, states that the first 
tergum had black bases and that a black me- 
dian line extended over terga four and five. 
Ovipositor: Very elongate, extended (Fig, 
24^) it measures 7.26 mm. The piercer is 
about 2.13 mm. long by 0.21 mm. wide at 
its widest point. Two large and two small 
preapical setae are present (Fig. 24c). The 
distal pair are situated about 0.02 mm. from 
the apex. The opening of the oviduct is about 
0.15 mm. from the apex of the piercer. The 
inversion membrane is about 3.0 mm. long 
by 0.83 mm. wide at its widest point. The 
rasper is situated about 1.27 mm. from the 
base of the segment. The basal segment is 
2.13 mm. long by 1.48 mm. wide measured 
across its hind margin. The spiracles are lo- 
cated about 0.31 mm. from the anterior lateral 
margins of the segment. 
Length: Body, 9.0-10.0 mm.; wings, 8.5- 
9.5 mm. 
TYPE LOCALITY: Makassar, Celebes. 
Cotypes are in the British Museum and in 
the Australian National Museum, Melbourne. 
Hendel’s specimen was from Formosa. The 
specimen discussed above is labeled ”Am- 
boina, F. Muir.”
