other than from the anterior ocellus; the style is much shorter, 
being about as long as the whole antenna; there are also minor

the thorax being to a large extent greyish white, and there are two 
rows of blackish spots on the abdomen, instead of one row as in

Type female from Mt. Bambata, Matopos, Southern

Wings very long and narrow, with the usual venation for the

face, as also under side of scutellum, with more abundant and 
longer, somewhat yellowish white pilosity. Dorsally on the 
abdomen the hairs are mostly black, except at the extreme base; 
the anterior third of the second tergite has a sparse, erect, long, 
black pilosity ; the remainder of the dorsal side bears many 
scattered, extremely short, slanting, rather stiff, black hairs. 
Ventrally the abdomen is but poorly covered; there are a few,
