currens\ the black lateral spots on the hind 
border of the third tergum ”not reaching” in 
recurrens (probably he means not continuous 
across the segment) and ”in manskii reaching, 
continued on fourth and fifth terga.” He says 
also that manskii differs by lacking the brown 
spot at the lower eye margin and in having 
shorter wings ("wing 5 mm. [in recurrens] and 
3.6 mm. in manskii"). The brown spots are 
usually present below the eye margin, and all 
the specimens of manskii on hand have a wing 
length of 5.0-5 .4 mm. The coloration of the 
thorax shows some variation, and some speci- 
mens have extensive black markings on the 
dorsum as well as on the pleura. D. manskii 
may possibly be a synonym or a subspecies 
of recurrens. Mr. May, in correspondence, 
stated that he did not consider the darker or 
lighter colorings to be of any value in this 
case since there is considerable variation de- 
pending upon the age (before killing) of the 
specimen. One specimen (from the type 
locality and host) received for study from 
Mr.^ May has the mesonotum extensively 
blackened and would fit the original descrip- 
tion of recurrens very closely. It will be neces- 
sary to study specimens of recurrens from New 
Guinea in order to be sure that these are 
synonyms. 
This species is distinguished from all other 
known Australian Dacinae by the conspicu- 
ous S-shaped band through the median part 
of the wing (see Perkins and May, 1949:4, 
fig. 1, and Hering, 1941^^:47, fig. 2). Wings: 
The band extends transversely across the wing 
from vein R4+5 through the r-m crossvein to 
the wing margin just below the apex of vein 
M3+4; it then extends dorsally along the m 
crossvein into cell R5 nearly to vein R4+5; 
then it curves downward again, extends along 
vein Mi +2 and ends in the wing margin just 
below the apex of this vein. The first two 
costal cells are brownish-yellow-fumose and 
are densely covered with microtrichia except 
in the basal part of the first cell. The costal 
band is very broad, filling all of cell R3. The 
cubital streak is broad, filling all of the basal 
part of ceirM4 up to the top margin of the 
m-cu cross vein. The narrowed portion of the 
cubital cell is slightly more than three times 
longer than the distance from the apex to the 
wing margin in the males and about two times 
longer in the females. Thorax: Chiefly reddish- 
yellow, typically with a pair of sublateral 
shining black stripes on the mesonotum just 
inside the postsutural yellow stripes. In 
the series at hand the coloration of the thorax 
varies considerably from specimens which are 
almost entirely reddish with brownish mark- 
ings on the dorsum to those which have the 
Fig. 19. Dacus {Strumeta) manskii (Perkins and May): 
a, ovipositor, full length; b, apex of ovipositor.
