and metanotum are distinct. Abdomen wider thari the 

 thorax. 



May be known from the type of the genus, T. trilobata, 

 Cam. (Ann. S. Afr. Mus., V, 32), by the shorter ovipositor 

 (4 mm with a body length of 5 mm in the latter), by 

 the middle lobe on the apex of the abdomen being hardly 

 developed and by the l st abscissa of the radius being longer, 

 not shorter than the 2 nd . 



Chelonus capensis, sp. nov. 



Black, the abdomen immaculate, the legs, except 

 the coxse and troch anters, red; wings hyaline, the 

 basal nervures pale, the others black, as is also the stigma, 

 the transverse basal nervure dilated at the parastigma; 

 the basal abscissa of radius straight, oblique, forming 

 an acute angle with the apical, which is also oblique, 

 but not so straight. Antennse as long as the abdomen, 

 tapering towards the apex, 25-jointed. Clypeus separ- 

 ated from the face by a smooth ridge, much less 

 strongly punctured than the face, which is closely rugose; 

 the front and Vertex are more distinctly punctured, the 

 punctures clearly defined; there are some longitudinal Striae 

 on the sides of the front, which form, with the punctures, 

 almost reticulations. Thorax somewhat strongly punctured, 

 the pleurse more closely than the mesonotum, and the 

 metanotum more strongly than the latter. Scutellum almost 

 smooth in the centre, the sides sparsely punctured; on the 

 transverse furrow at the base are 8 distinct keels. Ab- 

 domen finely granulär; the apical half covered with a 

 white down. $ 



Length 6 mm. 



Cape Colony (Drege). 



Parapsidal furrows on the basal two-thirds; at their 

 end the mesonotum is much more strongly punctured than 

 it is at the base. 



Characteristic of this species is the abscence of the 

 usual white spots from the base of the abdomen.
