in the liypopygial characters. The outer harpago is 
two or more times longer than wide and the inner is very 
differently shaped than in rex. The processes on the 
sixth segment of the abdomen are also distinctive. 
Male. Head: Eyes very narrowly separated on the 
front, nearly touching for half the length of the front. 
Front and face silvery gray pubescent. Mouth parts and 
third antennal segment bright yellow. First two antennal 
segments brown, ventral bristles of second as long as the 
segment. Third segment gently rounded below, shaped 
as in D. rex (Curran). Thorax: Pleura yellow brown in 
ground color, densely gray pollinose. Dorsum black, 
covered chiefly with brownish pollen. Propleura bare 
dorsocentral hairs very small and inconspicuous; mar- 
ginal fringe of scutellum distinct but the hairs are short 
and tine. Humeri, tegulse and knobs of halteres dark 
brown to blackish. Legs: Coxae and femora chiefly dark 
brown, the latter with yellow bases and apices. Trochan- 
ters, tibiae and basal subsegments of tarsi yellow; the 
apical subsegments blackish. All femora silver pollinose 
on the posterior side and with a row of fine cilia near the 
upper portion of the posterior side. Flexor spines pre- 
sent only on the basal one-third to one-half of the middle 
femora, absent on the other legs. Middle coxae with a row 
of black bristles at apices above. Hind tibiae without 
strong erect bristles on the swelling. Wings: Very 
lightly fumose, stigma brown and filling all of the third 
costal section. Third section slightly longer than the 
fourth, the two combined are slightly longer than the fifth. 
The r-m crossvein is located at the basal third of the discal 
cell and the last section of the fourth vein is strongly 
curved. Abdomen: Chiefly dark brown with broad gray 
fasciae on apical halves of segments, these are broadly 
interrupted with brown in the middle. Hypopygium: 
Similar in general appearance to D. rex except that the 
apical membranous area is not so large (Fig. 2a). The 
outer harpago is two times longer than wide and oyer one- 
third as long as the inner harpago. The inner is greatly 
enlarged on apical half and also produced on inner side 
of basal portion (Fig. 2b). The sixth abdominal segment
