and not inf umate ; upper basal iiervure postfurcal ; areolet pentagonal 

 and not large, emitting the angled and bifenestrate recm-rent nervure 

 from but slightly beyond its centre ; nervellus postfurcal and straight, 

 intercepted at its lower third. Length, 12 mm. 



The type was captured at Bulwar in Natal by W. Hay garth.

In the same monograph, I have referred to this species' occurrence 

 in Asia, Africa, Australia, and its erroneous record from Europe. It 

 is known throughout Central Africa; but none were hitherto captured 

 so far south as the following typical example.

$ only. A slender, clear testaceous species with the head except 

 mandibles and palpi and clypeal margin, antennae except underside 

 of scape, and the anus from base of the fifth segment, dead black ; 

 flagellum discally white-banded beyond its centre ; and the wings 

 fulvescent with stigma luteous. In structure it differs hardly at all 

 from /. luteator : the face is shorter, the hind coxae are distinctly 

 more sparsely punctate below, the eyes a little less prominent ; and 

 the wings are narrower, with the discoidal cell a little longer and 

 narrower, and the radial distinctly narrower with the apical radial 

 abscissa straighter. It is, however, abundantly distinct in its im- 

 maculate legs, black head and pale-banded antennae. Length, 12 mm. 



No nearer locality than South Africa is assigned the type.

Essential Characters. Metanotal areolar carinae entirely wanting ; 

 wings not hyaline; species testaceous. Apophyses distinct; scutellum 

 not strongly convex ; areolet pentagonal and of normal size. Flagellum 

 of $ more or less strongly dilated and of $ serrate. Segments but 

 little discreted, neither angularly produced nor aciculate.
