NOTES ON AFRICAN CHALCIDOIDEA — V. 129» 



a southern form of it, but certainly deserves a separate name. Some interesting- 

 differences in the hind legs are illustrated in fig. 4. The short heavy spine at the 

 apex of the tibia is constant for sycomori, but the similar spines along the ventral edge 

 are less constant. In cydostigma there are no peg-like spines anywhere on the tibia. 



CoLPiXYS, gen. nov. (Entedoninae). 



$. Head with distinct occipital edge ; eyes hairy. Antenna cyHndrical, narrow ;: 

 scape, pedicel, triple ring joint ; funicle three joints, the first very long ; club two- 

 jointed. Pronotum with lateral thickening at the spiracle, which is half surrounded 

 by a smooth rim, prosternum much produced anteriorly ; mesonotum flat, with four 

 bristles on the mid lobe ; propodeon with three sulci, one median and one round each 

 spiracle. Fore wings : submarginal wth two bristles, an isolated row of isocUnal 

 bristles parallel to the hind margin. Abdomen depressed, elongated. 



Colpixys necator, sp. nov. 



Scape, except narrowly at apex, and ring joints clear and pale ; pedicel, funicle, 

 and club blackish brown. Head, thorax, coxae, and abdomen rich dark blue-black,, 

 dulled, except on propodeon and abdomen, by the deep sculpturing of the integument. 

 Near the base of the abdomen and on the propodeon the coloration is metallic, and 

 dark green overhes the blue in some lights. The blue of the coxae is also partially 

 metalhc. Veins pale, a little infuscated, tegulae darker. Hind legs from trochanter 

 onwards entirely pale. Mid legs pale with a dark apical ventral streak on the femur 

 reaching back over one-third ; tibia with trace of a superior brown streak basally ; 

 tarsus a little darker than that of hind leg. Fore femur brownish above, paler 

 beneath, tibia (superiorly) and tarsus smooth, the former pale beneath ; claws dark 

 brown. 



Head very broad, wider than deep (9 : 7) ; eyes far apart, the interval varying- 

 from 3 (at the level of the anterior ocellus) to 3| (at the base line of the eyes) times. 

 an eye diameter ; the eyes two-thirds of the depth of the head ; distance between 

 posterior ocelli to that of either from the orbit in the ratio 5 : 3. Anterior ocellus 

 large, rounded, quadrate ; toruli just above the base line of the eyes, oval, nearly 

 circular ; mouth-edge somewhat above the projecting genal angles, practically 

 straight. Sculpture on frons, vertex and occiput coarse, regular, raised reticulate,, 

 finer towards the clypeus and for a short distance outside the genal keel ; the latter 

 distinct. Clypeal edge narrowly smooth ; many fine bristles on genae and occiput, 

 some of the latter appearing over the well-defined occipital ridge, in front of which 

 there is one strong bristle at each side between the posterior ocelli and the eyes. 

 Three bristles within the ocellar triangle ; another pair towards the sides (1 : 1) 

 above the level of the anterior ocellus, below which there is one bristle, inwardly 

 directed, on each side half-way between the mid line and the orbit. About twelve 

 bristles on each orbit, and two well above the cl;y'peal edge in the middle ; two smaller 

 project from below. There are, besides, numerous bristles bordering the orbits (each 

 of them rising at the corner of a raised cell), but not very regularly disposed ; about 

 sixty in all (30, 30). The eyes are clothed with a moderately long, fine pubescence ; 

 they hardly appear, in side view, above the level of the vertex. Face with practically 

 neither post-scapal hollow, nor trace of suture.
