This species is distinguished by its very 
short and broad ovipositor, its pale reddish 
to yellow thorax, and by the lack of a median 
vitta on the abdomen. It is most closely 
related to D. hreviaculeus n. sp,, but is easily 
separated by the characters noted above as 
well as by a comparison of the female ovi- 
positors (Figs. 11^ and 12c). 
MALE. Predominantly pale species with 
brown to blackish markings only on the sides 
of the abdomen and sometimes on the pleura. 
Head: The frontal and the occipital bristles 
are dark brown to black, the other head 
bristles are brownish-red to yellow-red. There 
are two pairs of inferior fronto-orbital 
bristles. The front is nearly two times longer 
than wide and is but slightly discolored in 
the median part. The area around the bases 
of the frontal bristles is not discolored. The 
facial spots are large, almost circular, and 
extend to near the oral margin. The third 
antennal segment is brown to blackish on 
the inner dorsal surface. The third segment is 
about one and one-third times longer than 
the face (measured on a mid-line) and is 
nearly five times longer than wide. Thorax: 
Scutellum, humeri, etc., yellow, and with 
broad postsutural yellow vittae on the sides 
of the mesonotum. These vittae extend from 
the suture to just beyond the bases of the 
inner posterior supra-alar bristles. Except for 
the yellow markings the entire mesonotum 
is reddish in ground color. This ground color 
is partially obscured by dense gray pruinosi- 
ty. This pruinosity is indistinctly divided by 
three subshining lines running longitudinally 
the full length of the thorax; one of these is 
median and the other two are submedian in 
position. The scutellum has a narrow brown- 
ish band at its base. The sternopleura and the 
anterior margins of the mesopleura are brown 
tinged. The yellow mark on the mesopleura 
is broad on the dorsal one-half to two-thirds 
of the sclerite and narrowed below. In the 
upper portion the spot covers three-fourths 
of the top margin of the sternopleuron. 
Legs: Entirely yellow except for the brownish 
discoloration on the hind tibiae. Wings: 
First two costal cells hyaline and devoid of 
microtrichia except in the apical portion of 
the second cell. Costal band and cubital 
streak distinct and brownish in color. The 
costal band is comparatively narrow but 
does extend a short way into cell R3 and a 
short distance into cell R5 at its apex. The 
cubital streak is broad and fills all of the
