fascia on first tergite narrowed and narrowly interrupted at mid- 

 dorsal line; broad fasciae on tergites 2-5, all slightly sinuate on 

 posterior dorsal border, that on 2 inclosing pair of large, elliptical 

 spots and acutely emarginate at median anterior border, that on 3 

 biemarginate, and those on 4 and 5 bisinuate on anterior border; 

 apex of sixth tergite; pair of small anterior spots on sternite 2; 

 lateral spots connected by very narrow apical lines on sternites 1-5, 

 each apical line apparently interrupted at mid-ventral line by a dark 

 ferruginous spot ; legs, except more or less of basal joints, line above 

 on all femora, narrow line below on tibiae, and small spot or line at 

 base above on tibiae; yellow. 



The flagellum below is ferruginous; above it is quite dark but 

 shades to ferruginous at the apex. The anterior metatarsus is pro- 

 vided with six spines, of which the basal one is quite small. The 

 wings are hyaline and very long, reaching the end of the abdomen. 

 The second abscissa of both radiella and cubitella is present. The 

 frons between the antennae and the adjacent basal part of the clypeus 

 are distinctly carinate. The sixth tergite is coarsely punctate and 

 the apical part is distinctly ferruginous. The sixth sternite is dis- 

 tinctly carinate on the midline and, like the sixth tergite, its apex is 

 marked with ferruginous. The disk of the second sternite is smooth 

 and shining and bears numerous, scattered, coarse punctures. 



The paratype (female) differs from the type in having the fascia on 

 the scutellum interrupted at midline ; in having the fascia on the first 

 tergite reduced to lateral spots; in having the inclosed spots on the 

 fascia on the second tergite reduced to anterior emarginations ; and 

 in having the fascia on tergite 5 narrowly interrupted at the mid- 

 dorsal line. The ferruginous markings on the sixth abdominal 

 segment are present, but less well developed than on the type. 



Length 22 mm. Described from two females, each of which bears 

 the label, " Nyassa-See, Langenburg, 9-19-VIII, 98, Fiitteborn S."

I have at hand a single female that I have referred to this species. 

 The second sternite (third and fourth also) is entirely yellow; the 

 sixth tergite bears lateral spots ; the fasciae on the tergites are broad 

 and only the first is narrowly interrupted. These fasciae on the 

 tergites have their anterior borders yellow and the posterior part 

 white. The scutellum, metanotiim, and propodeum each bears a 

 prominent fascia ; there is a prominent U-shaped discal mark on the 

 scutum; and there is a pair of black spots on the clypeus. The
