of the segment. The basal portion of the 
ovipositor is 1.56 mm. long by about 1.4 
mm. wide at its widest point. The spiracles 
are situated about 0.62 mm. from the anterior 
lateral margins of the segment. 
Length: Body, 7.5 mm.; wings, 6.0 mm. 
Male unknown. 
Holotype female is labeled "Pontianak, 
Borneo, F. Muir.” The type has been returned 
to the Hawaiian Sugar Planters’ Association 
collection.

This species is readily recognized by its 
predominantly blackish coloration as stated 
in the key and as discussed in the comparison 
with D. luzonae n. sp. The species has been 
adequately described by Perkins except for 
the details of the ovipositor. 
Ovipositor: The basal portion {in situ) is just 
slightly longer than the fifth abdominal seg- 
ment. The extended ovipositor (Fig. 18^) 
measures approximately 4.37 mm. The piercer 
is 1.35 mm. long by 0.15 mm. wide at its 
widest point. The opening of the oviduct is 
situated about 0.25 mm. from the apex of the 
piercer, and the preapical setae are 0.07 from 
the apex (Fig. 18c). The inversion membrane 
is 1.77 mm. by 0.26 mm., and the rasper ex- 
tends to within 0.6 mm. of the base of the 
segment. The basal segment is 1.25 mm. by 
1.0 mm., and the spiracles are situated 0.28 
mm. from the anterior corners of the segment. 
Length: Body, 6.0-7. 5 mm.; wings, 5.5- 
6.0 mm. 
TYPE locality: Larut Hills, Perak, Malaya. 
Type in the Selangor Museum. 
We have studied two paratypes.

Perkins separates this from the typical form 
by the broader costal band, filling almost all 
of cell R3. He also says it differs by having 
the occiput fulvous, the postsutural yellow 
stripes broader, and by its larger size. 
Length: Body, excluding ovipositor, 9-0 
mm.; wings, 7.5 mm. 
TYPE locality: Kedah Peak, Malaya. 
Type in the Selangor Museum. 
We have not seen this variety.
