Some New Genera and Species of Hymenoptera. 223 



There is an obscure rufous line on the sides of the pronotum, an 

 obscure rufous streak runs from the ocelli to the antennal keel, 

 which is yellowish, bordered by rufous. The depressed base of the 

 second and third segments black ; the second segment may be 

 broadly black at the base and the fifth narrowly ; the antennae may 

 have the apical joints black above. 



Oeeceris pearstonensis, sp. nov. 



Black, a broad line, roundly narrowed above and below, on the 

 centre of the inner eye orbits, antennal keel, a line on the outer 

 side of the pronotum, tegulae, post-scutellum, the third abdominal 

 segment except for a broad curved black band in the centre of the 

 base and a broad, irregular band on the apical half of the fifth, 

 yellow ; the first segment and the second, except for a broad curved 

 mark on its apex, red ; legs black ; the greater part of the fore 

 femora and the four front tarsi rufous ; all the tibiae white on 

 the outer side. Flagellum of antennae for the greater part brownish. 

 Wings hyaline, the apex smoky. ? . 



Length 9 mm. 



Cape Colony. Pearston. 



Third antennal joint shorter than the scape and about one-quarter 

 longer than the fourth. Front and vertex closely and strongly 

 punctured. Face and clypeus thickly covered with silvery pubes- 

 cence ; the face and base of clypeus sparsely punctured ; the apex 

 of clypeus obliquely incised ; the sides of the incision straight, 

 forming a sharp angle in the centre and sharply projecting below, 

 the lower edges forming sharp teeth ; the lateral edges roundly, 

 broadly incised, the apical roundly projecting. Mandibles yellowish 

 at the base, reddish in the centre, black at the apex. Pro- and 

 meso-notum distinctly punctured, the punctures clearly separated ; 

 the scutellum more sparsely punctured; pleurae closely, coarsely 

 rugosely punctured. Metanotal area longer than its width at the 

 base, smooth ; a row of deep punctures down the centre, the 

 punctures close to each other and wider than long. Pygidium 

 slightly narrowed towards the base and apex ; slightly, irregularly, 

 obliquely striated ; its apex oblique, bordered by a rounded keel 

 above; apex of epipygium with a rounded incision, not extending to 

 the middle. 



The amount, of red on the second abdominal segment varies, it 

 may be present on the extreme base, or the segment may be entirely 

 red. Comes near, apparently, to C. albifrons, Sm., of which the 

 male only has been described very imperfectly.
