Dacus (Strumeta) transtillum 
(Hering), n. comb. 
Strumeta transtillum Hering, 1952, Treubia 
21(2): 265-266, fig. 1. 
This appears to be closely related to D. 
cucurhitae Coquillett but is readily separated 
by the black transverse band across the face 
and by the narrow costal band in the wing; 
the band does not extend into cell R3 except 
at the apex. 
Length: Wing, 5.3 mm. 
We have not seen this species; it is known 
only from the type female, 
TYPE locality: Idjen, E. Java, host un- 
known. 
Type in the Leiden Museum.

Java, not New Caledonia). 
This species is readily recognized by the 
presence of three transverse bands across the 
wing (Fig. 22a), by the all-yellow or rufous 
scutellum, and by the presence of just two 
pairs of inferior fronto-orbital bristles. It 
is closely related and is possibly conspecific 
with D. frenchi Froggatt (1909: 92). Bezzi 
(1919: 417) and others have considered D. 
frenchi to be a synonym of D. umbrosus Fabri- 
cius. Perkins (1939: 13) regarded them as 
distinct species which can be separated on 
the basis of size, color of abdomen, and by 
the position of the r-m crossvein. The writers 
have not studied specimens from New Cale-

donia or New Hebrides so cannot confirm 
Perkins’ conclusions. Specimens of Dacus um- 
brosus are on hand, however, from a wide 
range extending from Malaya through the ■ 
Netherlands Indies, the Philippines, New 
Guinea, and New Britain. Specimens from '= 
the Philippines possess the black lateral mark- ^ 
ings on abdominal terga three and four which, r 
Perkins says, distinguish frenchi. They range 
in size, however, from about 7.0 to 8.0 mm. 
for the males, instead of 8. 5-9-5 mm. The 
writers have not been able to detect significant 
differences in the position of the r-m cross- 
vein and doubt the taxonomic importance of 
the slight degree of difference in umbrosus and 
frenchi which has been noted by Perkins. ' 
The ovipositor has not been described pre- ’ . 
viously. The visible portion of the ovipositor , 
is about equal in length to the fourth and j 
is equal in length to the fifth. The extended > | 
ovipositor (Fig. 22b) is approximately 6.7 mm. ir
