Face and clypeus densely covered with moderately long white 

 pubescence, the thorax with denser darker pubescence, which 

 is longer on the metanotum; the ventral surface sparsely covered 

 with white hair. Head opaque, impunctate; there is a stout keel 

 on the middle of the front, commencing near the ocelli and with a 

 few oblique strias on either side. Mesonotum closely, regularly 

 reticulated; a smooth line, with a keel in the centre, in the 

 middle of the basai half and there is a less clearly defined line on 

 the sides. Scutellum coarsely transversely rugose. Metanotum 

 closely transversely striated, the strias closely waved. Pleuras lon- 

 gitudinally striated, the base of the propleurœ smooth, the strias 

 more widely separated than they are on the mesopleuras, on which 

 the strias are stronger and more widely separated on the upper 

 third than on the rest; the metapleuras more strongly obliquely 

 striated, the strias weaker at the base. Metanotum somewhat 

 strongly transversely striated, the apical slope with the strias 

 closer, almost forming reticulations. Pétiole smooth, the post- 

 petiole strongly, but not closely putictured, the punctures in the 

 centre of the base sparser; the 2 nd and 3 rd segments are more 

 finely, and much more closely punctured, more strongly on 

 the base than on the apex and almost forming reticulations; 

 the 2 nd segment is narrowed at the base. 



This species may be known from the type of the genus, the 

 Natal C. ruficeps Cam., by the latter having the head red, and the 

 base of the wings black, there being only one hyaline cloud. 



OPHIONIN.E 



Ophion congoensis sp. n. — Pale reddish yellow, the 

 antennas more rufous in tint; the orbits pallid yellow; wings clear 

 hyaline, very iridescent, the costa and stigma rufo-testaceous, the 

 nervures black; the disco-cubital nervure without a stump, ner- 

 vellus shortly post-furcal; the transverse cubital nervure hardly 

 one fourth shorter than the récurrent. Ocelli black. Mesonotum 

 finely, closely, but distinctly punctured; the pleuras more strongly 

 punctured ; the upper basai half of the pro- and the lower half of the 

 mesopleurœ more or less striated; the metapleuras closely, more 

 rugosely punctured. Temples short, obliquely roundly narrowed. 

 Ovipositor short, scarcely reaching from the middle of the apical 

 segment to its ventral surface. Ç. 



Length 15 mill.
