282 8JOSTEDT8 KILIMANDJARO-MEBTJ EXPEDITION. 8: 7. 



Face and clypeus densely covered with silvery pubescence; the apex of the latter 

 transverse. There is a longish, slout keel between and below the antennae; from the 

 outer side of each antenna a narrower keel runs down, the 2 uniting below, where they 

 are rounded on the outer edge, the whole forming an area wider than long. Front and 

 vertex shining, finely, closely punctured. Pro- and rnesothorax sparsely, weakly punct- 

 ured, the apex of mesopleura 3 smooth, as is also the base of the metapleurae; the rest 

 of the latter coarsely, closely reticulated. 



Pseu bidentatns, sp. nov. 



Black, the basal 5 joints of the antennae and the apical below, mandibles except 

 at apex, the four anterior femora except below, the apex of the 1st abdominal segment 

 narrowly and the others entirely, rufo-ferruginous, the apices of the 4 anterior tibia 1 and 

 their tarsi testaceous. Apex of clypeus ending in 2 blunt teeth or tubercles. Wings 

 hyaline, the nervures black; the 2nd abscissa of radius half the length of the 3rd; the 

 1st recurrent nervure interstitial. Front between the antenna? with a large flattened 

 spine. $. - - Length 9 mm. 



Kilimandjaro : Kibonoto, cultivated region. 4th May. 



Front closely, distinctly, but not very strongly punctured; the centre with a clearly 

 defined keel; the vertex smooth, sparsely pilose. Face closely, minutely punctured, separ- 

 ated from the clypeus by a narrow curved furrow; its top is bounded by a distinct, 

 curved furrow. The pubescence on the face and clypeus is short and sparse; on the 

 outer orbits dense and silvery. Base of pronotum bordered by a raised, stout keel. 

 Mesonotum and scutellum punctured, but not closely, nor strongly; there are 2 fine 

 furrows on the basal slope of the mesonotum and one on the sides opposite the tegulse. 

 The scutellum is punctured like the mesonotum; the post-scutellum is much more closely 

 punctured and more densely haired. The metanotal area is large, smooth; its bounding 

 keels lead into the central furrow; in the centre are 2 oblique keels and on the outer 

 edges are 2 short ones; the top of the furrow is bounded by a narrow curved keel; the 

 upper half of the furrow is of equal width; the lower part is wider and becomes widened 

 gradually below; on its top are 3 transverse keels; the apical slope is irregularly obliquely 

 striated. The upper keel on the pronotum extends half way down the propleura?; the 

 base of the latter is margined and ends below in a large triangular tooth; the centre of 

 propleura? is striated, widely above, closely below. Mesopleurse somewhat strongly punct- 

 ured, the apex smooth and with an oblique furrow dow r n the middle; the basal vertical 

 furrow marked with stout . keels. Metapleurte finely, closely obliquely striated ; below the 

 spiracles are a few stouter stria?. The pubescence on the sternum and metathorax is 

 denser than it is on the rest of the thorax. 



Ampulex melanocera, sp. nov. 



Green with brassy tints, the flagellum of antenna^, except at the extreme base, 

 black; the tibia 3 and basal joint of the tarsi blue, the other tarsal joints black; wings
