(S. A. Newve); also 1 #1 9 from other Rhodesian localities 
and 2 f.1 2 Salisbury (@. Marshall). The author’s name 
is on a f from Salisbury (1895), which is regarded as the 
type of the following description. 
The 2, which has not before been described closely, 
resembles the 9, but the head and thorax are densely 
clothed with short hoary yellowish pubescence that hides 
the sculpture, the wings are hyaline with only the very 
faintest tinge of yellow, and the transverse yellow bands 
on the segments of the abdomen above are very broad and 
deeply excavated on each side. In the ? these bands are 
only slightly laterally excavate.
