on the scutellum. Although I could see no flat scales on the 
mesonotum in the type, they can be easily detected in the var. 
alba , and have been most probably denuded off. 
Yar. alba. 
Head with flat white scales at the sides and on the sides of 
the occiput. Thorax bright rufous; pleurae pale ochraceous, 
with patches of flat white scales and a patch at the borders of 
the mesonotum just in front of the wings; abdomen with the 
second and fourth segments with broad apical white-scaled bands, 
a, Cross-veins ; b, male ungues of fore leg. 
the last segment with an apical median white-scaled patch. 
Posterior cross-vein more than twice its own length distant from 
the mid cross-vein, only about one and a half times its length 
distant from the junction of the anterior branch of the fifth vein 
with the stem. 
Length.—2 • 5 mm. 
Habitat. —Salisbury, Mashonaland (Marshall) (79). 
Time of capture. —March. 
Observations .—A single specimen, so much like the type 
structurally that I think it must be merely a variety with apical 
bands to some of the segments of the abdomen, and more white 
scales on the sides of the head and on the sides of the pleurae 
and mesonotum. I can only see the mid and hind claws which 
resemble those of the type. 
11. UraNotaenia minima, n. sp. 
Thorax deep brown (denuded), with long black bristles • 
metanotum with a pale median line. Abdomen dark brown, 
with narrow basal bands of pale yellowish-brown; pleurae and 
coxae very pallid. Small sized (2 mm.).
