Some New Species of Hymenoptera. 329 



The long scutellar spine of almost equal width and with the sides 

 yellow distinguishes this species. In capensis the spine is black to- 

 shortly beyond the middle, the apex yellowish testaceous ; in spini- 

 ferus it is much broader compared with the width, and is narrowed 

 at the base ; there is a stout keel down the middle of the scutellum ; 

 the central area on the metanotum is large and reticulated, the apex 

 of the clypeus is not transverse, and the legs are largely bright 

 lemon-yellow. 



In cethiopicus the keel leading from the metanotal area is broad 

 above, becoming narrower below ; it is flat, smooth and shining. 



ICHNEUMONIML 



Hemitelini. 



Gen. XENOLYTUS, Forst. 



Xenolytus rufipes, sp. nov. 



Black, the abdomen from the second segment and the legs rufous ; 

 the legs darker in tint than the abdomen, the hind coxae black ; the 

 basal four or five joints of the antennas dark red ; wings hyaline, the 

 nervures and stigma black. 5 . 



Length 5 ; terebra fully 1 mm. 



Antennas 19-jointed, stout, as long as the abdomen, the third 

 joint slightly longer than the fourth ; the last not quite so long 

 as the preceding two united. Head and thorax shining, covered with 

 a minute pile. Face closely, minutely punctured, opaque ; the 

 clypeus smooth and shining. Mandibles dark red, the teeth black ; 

 the upper is distinctly longer than the lower. Palpi dark testaceous. 

 Thorax shining, closely, minutely punctured, the mesonotum more 

 closely and strongly than the rest ; the base of metanotum distinctly 

 depressed ; the basal area large, almost square ; the areola large, 

 6-angled, transverse at base and apex ; the basal half obliquely 

 narrowed, about one-third narrower than the apex ; there are two- 

 large basal lateral areae ; the apical is broad at the base, narrowed to 

 a point at the apex ; its inner side roundly curved ; it forms almost 

 a triangle ; posterior median area occupies the entire apical slope ; 

 it is 6-angled. The middle of the mesopleurae is smooth and 

 shining ; below it is obscurely, finely longitudinally striated..
