Parasites of the Mealie Stalk Borer. 335 



The cocoon is elongate-ovate, white, covered on the outside 

 with longish hair. The insect escapes by a round hole near 

 one end. 



Apanteles sesamle, sp. nov. 



Black, very smooth and shining except the metanotum and basal 

 segment of the abdomen, which are opaque and coarsely shagreened. 

 Basal half of flagellum fuscous ; the legs rufo-testaceous. Wings 

 hyaline, the stigma and nervures fuscous. $ . 



Length nearly 2 mm. 



Cape Colony. Grahamstown (11th September). 



Antennae stouter than usual, not much longer than the head and 

 thorax united ; the third joint twice longer than thick, clearly longer 

 than the fourth which is longer than thick ; the others are as long 

 as thick. Face rounded ; separated from the clypeus by a distinct 

 furrow. Temples broad, rounded. Mesonotum depressed, flat, its 

 apex raised. Metanotum not areolated or keeled. First abdominal 

 segment wider than long ; its sides depressed ; the depressions wide, 

 clearly denned ; the second is shorter, broader than long, aciculated, 

 more shining than the first, but not so much as the following 

 segments ; the ovipositor distinctly projects, is stout, broad ; the 

 apical ventral segment is testaceous. The apices of all the segments 

 are transverse. The legs appear to be stouter than usual ; the spurs 

 of the hind tibiae are stout and are nearly as long as the second tarsal 

 joint ; the hind coxae smooth and shining. The first cubital cellule 

 is large, its apex broadly, roundly curved ; there is a short stump of 

 the cubitus beyond it. 



The antennae are thicker, the mesonotum more shining and 

 depressed and the nervure bounding the first cubital cellule more 

 rounded than they are in most European species. Against the light 

 the cubitus can be traced to the apex of the wing ; at the base it is 

 straight, oblique. The praediscoidal areolet is more than twice 

 longer than it is wide at the apex, where it is straight, oblique. 



ICHNEUMONID^E. 



EXEPHANES NIGROMACULATUS, Cam. 



Annals of the South African Museum, Vol. V., 1906, p. 161. 

 The example bred is a J , which has not been described. The 

 basal third of the antennae is red, the rest black except for a white 

 band of five joints near the middle ; the apical joints are serrate.
