86 Annals of the South African Museum, 



Sides and apex of scutellum keeled, base of metanotum keeled, 



body not maculate with yellow. 



Tibiae (especially the four anterior) thickened, contracted at 



the base, body red Erythrophion. 



Tibise slender, not contracted at the base, body black . . . . Stictophion. 



Head, seen from the front, long, owing to the longish malar space. 

 Clypeus not separated from the face, its apex bidentate. Scutellum 

 roundly convex, its sides keeled, bordered on the inner side by a 

 furrow. Median segment coarsely rugosely punctured ; its spiracles 

 lai'ge, linear. Abdomen long, slender, compressed ; the petiole 

 narrow, cylindrical, its spiracles placed at the base of the apical 

 third ; those of the second in the middle. Radial cellule short, not 

 reaching to the apex of the wing ; transverse median nervure inter- 

 stitial ; recurrent nervure received behind the transverse cubital ; 

 transverse median nervure in hind wings unbroken. 



Ophioncura is further known from the two genera here described 

 by the very short malar space, the head therefore not being 

 rostriform. 



The temples are broad ; the occiput margined, roundly incised. 

 Mandibles unequally bi-dentate, the posterior much shorter than 

 the anterior, bluntly rounded, not projecting ; the apex of upper 

 bluntly rounded. Legs slender ; the spurs minute ; hind tarsi 

 stout, spinose. Basal two joints of flagellum of antennae about 

 equal in length ; the scape ovate, about twice longer than wide. 

 Base of metanotum without keels. 



The two species known to me may be separated thus : — 



Legs, the stigma, and base of antennae black tiif/ricans. 



Legs red, the stigma testaceous, base of antennae red rujipes. 



Stictophion rufipes, sp. nov. 



Black, the legs, except the coxae, red; the second and third 

 segments of the abdomen of a more obscure red colour; wangs 

 hyaline, the costa and stigma testaceous, the nervures black. <y . 



Length 14-16 mm. 



Cape Colony. Cape Town. 



Basal half of mandibles red on the inner side. Head thickly 

 covered with white hair ; the face closely, strongly punctured, the 

 sides on the upper part raised into a fold ; clypeus more strongly, 

 irregularly punctured, especially in the centre at the apex, where the 

 punctures run into strias. Front and vertex strongly and closely 

 punctured ; the former transversely striated in the middle. The
