cylindrical ovipositor which is "as long as the 
preceding part." The legs are yellow. The 
wings have a brown costal band which is 
dilated toward the tip and have two transverse 
bands connected to the costal band. 
Length: Body, 6.0 mm. 
TYPE LOCALITY: Batchian. 
Type in the British Museum. 
Dacus diffusus Walker, I860, Linn. Soc. Lon- 
don, Proc. 4: 153. 
Walker described this species as having a 
black band on the face and as having two 
short, narrow black stripes on the mesono- 
tum. The wings are "clouded with very pale 
brown about the veins." This may possibly 
be related to D. {Zeiigodacus) macuUpennis 
(Doleschall). 
Length: Body, 8.0 mm. 
TYPE LOCALITY: Makassar. 
Type in the British Museum. 
Dacus macultgera (Doleschall), 1859, Natuurk. 
Tijdschr. Nederland. Indie 17: 122 (Bac- 
trocera) . 
This species has been considered as a syn- 
onym of Dacus zonatus (Saunders) by some 
authors, but the synonymy cannot be con- 
firmed as we have not seen specimens from 
this area. 
TYPE locality: Sarawak, Borneo. 
Type in Vienna. 
Dacus ritsemae Weyenbergh, 1869, Arch. Neer- 
land. 4: 360, pi. 6, figs. 1-5. 
TYPE locality: Java. 
Bezzi (1913: 78) says "the type is in 
Amsterdam.^" 
Dacus strigifinis^dilktt, 1861, Linn. Soc. Lon- 
don, Proc. 5: 295. 
This may not be a Dacus. Bezzi (1913: 80) 
questioned its generic position. 
TYPE locality: Batchian. 
Type in the British Museum.
