Descriptions of New Species of Parasitic Hymenoptera. 101 



PANISCINI. 

 PANISCUS, Schr. 



Paniscus melanogaster, sp. nov. 



Dark rufous, the abdomen for the greater part black ; the 

 antennae of a lighter rufous colour ; the orbits, sides, and apex of 

 the clypeus yellow ; wings hyaline, the costa, stigma, and nervures 

 black. (J . 



Length 21 mm. 



Cape Colony. Neighbourhood of Cape Town. 



Face and clypeus closely punctured, the latter (especially below) 

 not so closely punctured. Mandibles tinged with yellow, black at 

 the apex. Clypeus separated by a furrow from the face. Scutellar 

 keels distinct, black. Except at the apex the metanotum is closely 

 transversely striated ; there is a large depression, bordered behind by 

 a keel, on the sides of the apex. Basal two segments of the abdomen 

 as long as the thorax. Disco-cubital nervure with a slight indication 

 of a stump of a nervure. 



Paniscus melanocotis, B6. 



This seems to be a variable species as regards the amount of black 

 on the head and abdomen and of yellow on the head and thorax. 

 The ocellar region may want the black, and the abdomen may be 

 blackish from the second segment. The stump of a nervure on the 

 disco-cubital may be distinct, indistinct, or even absent. 



BANCHINI. 

 EXETASTES, Grav. 



EXETASTES PERONATUS, Sp. nOV. 



Black, a line on the base of the mesonotum in the middle, 

 narrowed gradually behind and reaching near to the tegulse, a large 

 mark on the scutellum, commencing at the top of the basal slope, 

 a narrow one on the apex of the post-scutellum, tegulge, and 

 tubercles, yellow ; the apical four segments of the abdomen with 

 their apices narrowly lined with white. Legs red ; the coxjfi, 

 trochanters, apex of hind femora narrowly, apical half of hind tibia; 

 and the hind tarsi, black. Wings hyaline, the nervures and stigma 

 black ; the disco-cubital nervure broken by a stump of a nervure. 

 $ and (? . 



Length 10-11 mm. ; sheath of ovipositor 1 mm.
