Some New Genera and Species of Hymenoptem. 211 



Mesocomys pulchriceps, sp. nov. 



Dark purple, mixed with blue and brassy tints ; the head dark 

 purple on the sides of the vertex, the centre blue ; the front fiery 

 coppery red, the clypeus green ; antennae black, the scape rufo- 

 testaceous ; legs black, the tarsi and the fore femora and tarsi in 

 front testaceous ; wings hyaline, the middle clouded, except at the 

 base of the marginal vein, where there is a hyaline cloud of equal 

 width. 2 ■ 



Length 3 mm. 



Head closely, distinctly punctured, the vertex less strongly than 

 the rest; sparsely pilose. Thorax smooth, the pleurae very minutely, 

 indistinctly punctured ; the furrow on the pronotum testaceous. 

 Ovipositor shortly projecting, testaceous. There is a narrow testa- 

 ceous band on the base of the middle tibiae. 



Cape Colony. Graham stown ; Brak Kloof. 



FOSSOEES. 

 SCOLIIM3. 



Gen. DIELIS, Sauss., 



DlELIS ERIONOTUS, Sp. 110V. 



Black, thickly covered with long, white woolly pubescence, the 

 clypeus, except for a large triangular mark in the centre, labrum, 

 base of mandibles, a line on the apex of the fore femora and the four 

 anterior tibiae behind, yellow ; the calcaria and tarsal spines white ; 

 wings hyaline, the stigma and nervures black. $ . 



Length 18 mm. 



Cape Colony. Dunbrody. 



The hair on the head and thorax is longer and denser than in 

 most males, it hiding the sculpture ; it is sparser on the clypeus 

 which is smooth, impunctate, this appearing to be also the case with 

 the thorax, so far as can be made out through the dense hair cover- 

 ing. The black on the abdomen has a bluish tinge ; on the second 

 segment the band is dilated in the middle and still more so laterally; 

 on the third it is narrower but is more distinctly dilated in the 

 middle ; in both the lateral expansion extends beyond the middle ; 

 the bands on the other segments are narrow and are fringed with 

 golden hair.
