-/* S.IOSTEDTS KILIMANDJARO-MERU EXPEDITION. S: 7. 



broadly, - - more broadly late-rally than in the centre - the greater part of the tibia-, 

 the 4 anterior tarsi and the basal joint of the hind tarsi on the basal half, pale yellow. 

 The underside of the anlennal flagelluin brownish red. Wings hyaline, the apex clouded 

 from shortly before the apex of the radial cellule, the nervures black, the 1st recurrent 

 nervure received at the apex of the basal third of the cellule - - at about the length of 

 the pedicle. Metanolal area with 2 parallel keels down the middle, the space between 

 them stoutly transversely striated; the lateral space irregularly obliquely striated. Pygi- 

 diuni irregularly rugose on the basal half and aciculated. $. - Length 9 mm. 



Kilimandjaro: Kibonoto, 1300 1900 in. May. 



Face and clypeus densely covered with silvery pubescence, the hair on the vertex 

 sparse and black. Front and vertex closely, the face and clypeus sparsely punctured. 

 Thorax more strongly punctured than the head, the metanotum more closely than the 

 mesonotum ; the post-scutellum with a few fine punctures, almost smooth. 



The tf has the clypeus, the sides of the face broadly - the mark narrowed 

 above - - a mark, widened gradually below, leading from the antennal keel and the posl- 

 scutellum yellow; the pygidium is sparsely, strongly punctured; the apex roundly, shal- 

 lowly incised. The size of the yellow marks probably varies; the line on the post- 

 scutellum is interrupted. 



Cerceris rufiscutis, sp. nov. 



Black, the labrum, mandibles, except at base and apex, antennae, occiput, upper 

 half of outer orbits, scutellums, the 2nd abdominal segment, except for a broad black 

 line on the sides of the basal three fourths, and one down the middle of the basal 

 three-fourths, gradually narrowed towards the apex, a narrow line, widened laterally, on 

 the apex of the 4-th, the 5th except for a curved black line on the base, the whole of 

 the 6th, a triangular mark on the sides of the 4th ventral and the whole of the apical 

 2 ventral abdominal segments, rufous; the antennal keel, a broad, irregular line on the 

 lower part of the inner orbits, commencing shortly above the middle, an oblique mark 

 of equal width and more than twice longer than wide on the clypeus below it, a large 

 triangular mark, rounded and almost bilobate below on the middle of clypeus, a broad 

 line on the sides of the 1st abdominal segment, widest at the apex, the black central 

 line being widened in the middle, a small spot on the apex of the 2nd on the sides, a 

 line on the apex of the 3rd, widened at the sides, where it is more than half the length 

 of the segment, 2 large marks, narrowly separated, on the 2nd ventral, the space between 

 them at the base triangular, the black apex, narrow, widest in the middle, and an irre- 

 gular, transverse oval mark on the sides of the 3rd, pale yellow. Legs rufous, the coxa? 

 and trochanters black, the 4 hinder coxa? and trochanters yellow on the outer side; the 

 hinder tarsi infuscated. Wings hyaline, the apex of costal cellule narrowly, the radial 

 and the 4th cubital cellule smoky-brown, the apex of the hind wings narrowly and lightly 

 smoky; the 1st recurrent nervure is received close to the apex of the basal 3rd of Hi*' 

 cellule, the 2nd distinctly beyond the transverse cubital; stigma ochraceous, the nervures 

 black. 5- Length 13 nun.
