CAMERON, VESPIDAE. 193 



Ancistrocerus (Nortonia?) lineaticollis sp. nov. 



Black, the head and thorax densely, the base of abdomen sparsely covered with 

 longish fuscous pubescence, 2 small spots over the antenme (some times obsolete) a 

 narrow, but distinct line on the base of pronotum, one on the apex of the 1st, 2nd, 

 3rd (the line on the 2nd and 3rd extending to the ventral surface) and 4th and a short 

 one in the centre of the 5th, whitish yellow; the basal 5 joints of the antenme bright 

 red, the apical half, the scape and the pedicle black above, the other joints of a duller 

 brick red, black above; legs bright red, the coxa?, trochanters and basal two-thirds of the 

 femora black. Wings fuscous violaceous, the costa and stigma dark rufo-testaceous, the ner- 

 vures black, the teguhe rufous. Clypeus pyriform, a little longer than wide, the apex di- 

 stinctly bidentate. The sides and top of the upper half of the metanotum keeled, the keel dila- 

 ted below; the top of the keel rounded ; at the bottom of the sides is an oblique tooth. Apex 

 of post-scutellum transverse, its apical slope oblique. Base of thorax transverse, without 

 projecting angles. 2nd abdominal segment longer than it is wide at the apex. $. 



Length to end of 2nd abdominal segment 10 mm. - - Mem, rain forest, 3500 m. Jan. 



Temples wide, rounded. Abdominal petiole with a distinct neck at the base as in 

 Nortonia; the segment rounded at the base above, cup-shaped, closely, distinctly, but 

 not very strongly punctured. 



The a 71 is similarly coloured, except that the clypeus has a curved irregular broad 

 line on the sides of the lower two-thirds, the line roundly dilated on the innerside above; 

 its apex has a distinct triangular incision; the antennal hook is stout, narrowed towards 

 the apex and does not reach to the base of the llth joint. 



Odynerus (Nortonia) massaicus sp. nov. 



Black, the clypeus, mandibles, frontal keel, a line on the top of the outer orbits, 

 top of basal slope of pronotum broadly, the lower edge narrowly, the upper half of the 

 base of propleura? broadly, the apex narrowly, teguke, tubercles, antenna scape, and the 

 base and apex of the flagellum, rufous, as are also the abdominal segments narrowly 

 behind the yellow lines, the basal segment entirely below and the apices of the 3rd and 

 following dorsal segments; the 1st and 2nd with yellow lines on the apices, the 1st on 

 top only, the 2nd on top and bottom. Wings hyaline, the radial cellule from near the 

 base and the apical 2 cubital cellules broadly fuscous violaceous in front, the stigma dark 

 testaceous, the nervures black. Apex of metanotum on top forming 2 rounded lobes, 

 margined, reticulated below the keels, the rest finely, closely, transversely striated. The 

 base of the 1st abdominal segment is raised, the top of the raised part almost forming 

 keels, the sides oblique, the middle of the top slightly curving downwards; above this keel, 

 and clearly separated from it, is the ordinary transverse ridge of the Ancistrocerus group. 

 2nd abdominal segment longer than it is wide at the apex. Apex of clypeus with a 

 minute black tooth on eitherside. Antennal keel longish, the upper half furrowed. Legs 

 of a paler red than that on the body, the hind coxa? with a curved tooth near the 

 middle, its lower edge transverse. The puncturation on the head is close, on the thorax 

 it is closer. $. - - Length 1 mm. - - Kilimandjaro: Kibonoto, 1300 1900 m., llth May.
