tirely black except for a very narrow, abbre- 
viated, postsutural yellow vitta on each side. 
The humeri are black along their inner edges. 
Legs: The femora are chiefly rufous, the front 
pair is slightly discolored with brown; the 
others have brownish discolorations on the 
dorsal surfaces, near the apices. The front 
tibiae are yellow, the others are brown. Wings: 
The costal cells are faintly yellowish fumose. 
The second is almost entirely covered with 
microtrichia, only the basal portion is bare. 
The costal band is rather narrow, it does not 
extend into cell R3 except along the wing 
margin, and is not expanded at the apex. 
Abdomen: All black except for a narrow yellow 
to rufous band at the apex of the second 
tergum. Ovipositor: (Fig. 19) The basal por- 
tion is equal in length to abdominal segments 
four and five. 
Length: Body, excluding ovipositor, 7.0 
mm.; wings, 6.5 mm. 
TYPE locality: Aru Islands. 
Type in the British Museum. 
The specimens described above are from 
Amboina, Oct., 1907 (F. Muir).

This species is closely related to D. dorsalis 
Hendel and is often difficult to differentiate 
except by comparison of the ovipositors. The 
color characters which have been used to 
separate pedestris from dorsalis are somewhat 
variable and cannot be wholly relied upon. 
A series of specimens on hand from the Philip- 
pines and from Malaya appears to be pedestris, 
except that they do not always possess the 
broad black rings at the apices of the femora 
which were mentioned by Bezzi. Perkins 
(1938) does not refer to this character in his 
discussion of this species. Perkins said that 
pedestris differs from dorsalis "in having the 
occiput black, or very dark brown, with a

narrow fulvous border, the propleura mostly 
black, the coxae and trochanters either dark 
brown or black, fore and hind tibiae either 
dark brown or black, usually an oval patch 
on the outside of the fore femora and the 
postscutellum entirely black.” The color of 
the occiput appears to be of little or no value 
in this case as it is often discolored with brown 
to black in dorsalis. The anterior sclerite of 
each propleuron is discolored with brown to 
black in the large majority of the specimens 
of pedestris on hand and is typically rufous or 
yellow in dorsalis. The yellow-brown to black 
anterior and middle coxae and trochanters of 
pedestris appear to be useful in separating the 
species. These segments are paler, usually 
clear yellow in dorsalis. The front and hind 
tibiae are predominantly dark brown to black 
in pedestris, and the middle pair are discolored 
with brown to black on the basal one third 
to one half. Typical dorsalis have the front 
and middle tibiae chiefly yellowish, the mid- 
’dle pair are narrowly discolored with brown 
to black near their bases, and the front pair 
often are discolored along the outside edges. 
The hind tibiae of dorsalis are more yellow
