24O P. CAMERON. HYMENOPTERA. 



Length 7 mm. ; terebra 3 mm. 



Smooth and shining, the pubescence dense and white. The area on base of2 n( l abdominal 

 segment a little longer than it is wide at the base and with the apical projection about twice 

 longer than wide; it extends to the apical fourth of the segment; the bounding furrows are 

 wide, smooth; the latéral furrow wide, the basai area longish triangular and without an apical 

 keel; there are narrow smooth, transverse furrows on the base of the 4 th and 5* segments. 



11. Camploneiirus cultricaudis sp. n. 



Lorentz River, November. 



Head, thorax and legs ferruginous, the eye orbits and pleurae paler, more yellowish 

 in colour, the hind tarsi infuscated; wings almost hyaline to the récurrent nervure, a small 

 cloud at the inner side of the transverse basai nervure, touching the costa, more than the 

 posterior half of the ist and the basai half of the 2^à discoidal cellule and the radial, cubital 

 and posterior apical cellules fuscous, a narrow, curved longish hyaline, cloud in the hinder 

 part of the i st cubital cellule, running into a wider oblique, conical one, twice longer than 

 wide, outside the ist transverse cubital and récurrent nervures; the 2 n(i transverse cubital 

 nervure bullated at base and apex; the ist abscissa of cubitus bluntly angled at the base; 

 the transverse médian nervure received shortly beyond the transverse basai; the récurrent 

 nervure in the 2nd cubital cellule. The narrowed basai part of the i st abdominal segment is 

 dark rufous; the abdomen as wide as the thorax; smooth and shining, the apices ofthe 31'dand 

 following segments narrowly white, the area triangular, as long as it is wide at the base, the 

 apical keel not much longer than wide, extending to shortly beyond the middle ; the bordering 

 furrows crenulated ; suturiform articulation crenulated in the centre only, the 2 latéral branches 

 smooth; there are smooth furrows on the base of the 4* and 5 th segments. The sides of the 

 hypopygium black, with a longish white line on the outer edge, commencing at the apex of 

 the basai fourth and extending to near the apex, the black there being directed backwards 

 at the base on the outerside, like the point of a harpoon. 0. 



Length 8 mm., terebra 8 mm. 



12. Camploneiirus basiornatus sp. n. 



Heuvel Bivak, November. 



Ferruginous, the flagellum of antennae, tips of mandibles and the back of the abdomen 

 black; the basai hollow of ist abdominal segment yellow, tinged with red; the apices of the 

 apical 4 segments narrowly white, the ventral segments white, with the usual black spots, 

 the hypopygium black, lined above and below with white; the hind tarsi dark fuscous except 

 the basai half of the ist joint; wings fuscous, with the usual small hyaline 3 clouds, the 

 ist bordering the basai abscissa of the radius; the ist abscissa of cubitus broadly roundly 

 curved at the base; the transverse médian nervure interstitial; the récurrent nervure received 

 clearly in front of the transverse cubital; anal nervure issuing from the top of the post- 

 erior third. Ç. 



Length 8 mm.; terebra 3 mm. 



A slenderly built species ; the abdomen is as wide as the thorax. Smooth, shining, sparsely
