Eiolo curvinervis sp. a. — Rufo-testaceous, the stemma- 

 ticum and apex of mandibles black; wings hyaline; the stigmaand 

 nervures rufo-testaceous, the base of cubitus thickened, roundly 

 curved at the base; the l st transverse cubital nervure from near 

 the radius, the apex of the l st abscissa of the cubitus narrowly, the 

 2 nd more broadly at the base and the fore part of the récurrent 

 broadly, bullated, the l st and 2 nd cubitals and the 2 discoidals being 

 thus confluent; the 3 ld abscissa of the radius is roundly curved and 

 longer than the basai 2 united. Ç. 



Length 17 mill.; terebra 22 mill. 



Kasai : Eiolo (Waelbroeck), 16' h January. 



Smooth, shining, the mesonotum and scutellum weakly, the

Zèle maculiceps sp. n. — Testaceous, flagellum of antennse, 

 stemmaticum, tips of mandibles and ovipositor black ; wings hya-

 closely punctured. Mesonotum distinctly, but not very closely or 

 strongly punctured ; the furrows deep, weakly crenulated. Meso- 

 pleurae smooth above, below the furrow (which is wide, shallow 

 and curved) closely punctured. The metanotum is closely and more 

 strongly punctured, appearing almost reticulated. The l st abscissa 

 of the radius is half the length of the 2 nd . The apical joints of the 

 antennae are dark testaceous, the apices of the joints annulated 

 with black. $. 



Length 9 mill.

2 (1) Thorax and legs not black, head not yellow. 



3 (6) Head red. 



4 (5) l st abdominal segment striated throughout, a stronger keel 



in the centre, the strise on 2 nd not extending beyond the
