all black. In D. harringtoniae the abdomen is 
largely reddish with no black markings or 
crossbands. 
MALE. Head: All rufous except for the shin- 
ing black facial spots. The front is about two 
times longer than wide and is just slightly 
discolored in the median portion. Most of the 
head bristles are brownish-red, the fronto- 
orbital bristles are black. There are two pairs 
of inferior fronto-orbitals and one pair of 
superiors. The occiput is entirely pale. The 
facial spots (Fig. 18 ^) are moderately large, 
suboval in shape, and indistinctly pointed be- 
low; often drawn out into a distinct point as 
in fagraeus. Thorax: Chiefly rufous, with the 
usual pale yellow on the humeri, notopleura, 
etc., and with a yellow vitta on each side of 
the mesonotum from the suture to the pos- 
terior supra-alar bristles. The mesonotum has 
a narrow shining reddish-brown to blackish 
line extending down each side (inside the 
lateral yellow vittae) from the inner edge of 
each humerus to the scutellum. A median 
longitudinal vitta is also set off on the meso- 
notum by a subshining yellow-red line 
bisecting the grayish pruinosity which covers 
the dorsum. The bristles are typical of the 
subgenus. The metanotum is reddish-brown 
on the sides, yellowish in the middle. The 
mesopleural stripe is rather narrow and is not 
markedly expanded on the top portion and is 
scarcely broader than the notopleural calli. 
The halteres are clear yellow. Legs: All yellow 
except for brownish discolorations on the
