290 R.TOSTEDTS KILIMANDJAROMERU EXPEDITION. 8: 7. 



Trypoxylon massaicum, sp. uov. 



Black, the palpi and spurs pale testaceous, the head and thorax densely covered 

 with silvery pubescence, the wings hyaline, iridescent, the nervures black ; the front with 

 a large area, bounded by distinct keels; it extends behind the anterior ocellus, where it 

 is rounded, but projecting slightly in the middle behind; below the middle it becomes 

 gradually obliquely narrowed to a blunt, rounded point; it is almost twice longer than 

 wide. Metanotal area large, wide, widely furrowed in the middle, and bordered laterally 

 by a narrower furrow; the central furrow is more shining and more strongly striated 

 than the raised sides, the striation on which becomes finer and closer towards the apex; 

 on the sides and apical slope the striation is stronger, with the striae clearly separated. 

 Pro- and mesopleurse smooth; the metapleune obliquely striated, more closely and strongly 

 below. First abdominal segment as long as the following 2 united, its base flat above, 

 the apex not much dilated. Mandibles ferruginous. $ - - Length 13 mm. 



Kilimandjaro: Kibonoto, Obstgartensteppe. 14-th May. 



The form of the frontal area is not unlike what it is in T. scutifrons, SAUSS.; in 

 that species the basal part becomes gradually widened and the apex ends in a sharp 

 point; in the present species the basal part does not become widened and the apex is 

 distinctly rounded. Cf. KOHL, Denkschr. d. Mathem.-Naturwiss. d. K. Akad. d. Wissen., 

 1906, Taf. Ill, f. 3. In length, as compared with the width, it more resembles that 

 of Stroudii, GRIB., but in it the apex ends in an acute point. 



Bemfoex, FABK. 



The 3 species described here agree best with HANDLIRSCH'S Group 35 (Fuscipennis) 

 cf. Sitzung d. K. Akad. d. Wissensch. in Wien, (',. 11, 850. 



Bembex niassaica, sp. uov. 



Pale olive yellow, the upperside of the antennal scape, the flagellum, 2 oblique 

 pyriform marks on the top of the clypeus in the centre, the vertex, the black continued 

 to either antenna, the lines gradually narrowed below, the occiput except round the 

 edges, the mesonotum, except for a narrow line on either side of the centre of the basal 

 half and a broader line on the sides at the teguhv, the scutellums except round the 

 apices, the metanotum, except for a curved broad line, dilated below in the centre and 

 with a square dilatation in the middle above, a bilobate mark on the top of the pro- 

 pleurte, the lobes narrowed above, the posterior the larger, the lower part at the base 

 narrowly produced towards the base of the pleura 1 , the mesopleura?, except for a longish 

 line, gradually widened from the top to the bottom, a curved line below the hind wings, 

 one of equal width in the centre of the metapleune, the sternum, the basal half of the 

 1st abdominal segment, the mark roundly narrowed at the apex, a broad line on the 

 apex, slightly dilated in the middle, the apices of the 2nd, 3rd and 4th segments broadly, 

 the lines dilated in the middle, a curved line, not extending to the outer edges, on the
