the 4th segment with a narrow, the 5th with a hroad black band down the centre; the 

 apices of the 2nd to 4th abdominal segments narrowly pale yellow. Wings hyaline, the 

 apex narrowly smoky, the nervures and stigma black; the 3rd cubital cellule much nar- 

 rowed in front, it being there not the length of the distance between the 2nd recurrent 

 and the 2nd transverse cubital nervures, the accessory nervure in hind wings is received 

 at a good distance behind the cubitus. The front below, at the antenna?, projects into 

 a prominent, rounded, nose-like, projection, which is keeled in the centre. Clypeus, face 

 and the lower two-thirds of the inner orbits densely covered with depressed golden pub- 

 escence; the sides of the metanotum densely with silvery pubescence. 3rd joint of an- 

 tennae slightly, but distinctly longer than the 4th, and almost of the same length as the 

 5th. Pronotum at the apex clearly separated, the base rounded, the sides oblique. Meso- 

 notum and scutellum irregularly rugosely punctured; the scutellutn with the base broadly 

 rounded, flat; the post-scutellum has the middle depressed. Metanotal area smooth, bare, 

 and bearing 8 irregular keels; its apex with an oblique slope, smooth. The 2nd ventral 

 abdominal segment is broadly rounded at the base; it is coarsely shagreened. 



Length 11 mm. - - Meru low lands, December. 



A distinct species, not readily confrounded with any of the described African species. 



Abstract: Mutiltidce 43 species, including 42 new species. - Scoliidce resp. 12 

 and 7. Tiplnidce resp. 10 and 10. Myziinidce resp. 2 and 2. Pompilidce resp. 

 38 and 34. - - Sphegidce resp. 56 and 45. - Total resp. 161 and 140, incl. Usambara 

 173 and 149. 



Of the above (Hyin. 6.) enumerated 42 Vespidce (10 belonging to the Social wasps and 32 to the 

 Solitary), 35 are undescribed, including 1 New Genus. I find it difficult, in our present state of knowledge of the 

 Hymenoptera of German East Africa, to draw any trustworthy conclusions as to the Geographical relations of the 

 species dealt with in this Memoir, for the reason that however valuable the material collected so industriously 

 by Dr. SJOSTEDT is, it still can only be looked upon, at least as a whole, as representing the commoner 

 species inhabiting the Kilimandjaro District. Moreover, we know hardly anything of the species of the great 

 mountains of British East Tropical Africa and very few from the great mountain Ruwenzori. As regards the 

 known species from Kilimandjaro and Meru, they are, alike in the Fossores and Wasps, widely spread 

 species, found, like Sphex umbrosus, in all the warmer regions of the Old World, or, if they are confined 

 to Africa, range from Abyssinia to the Cape. 



A comparison of the list of species given in Ihis .Memoir with the list in Dr. H. STADELMANN'S Die 

 Hymenopteren Ost-Afrikas, shows some noteworthy features and also shows how valuable has been Prof. 

 SJOSTEDT'S contribution to our knowledge of East Tropical Africa's Hymenopterous Fauna. Thus no species 

 of Tiphia is recorded by Dr. STADELMANN, while no less than 10 have been found by Dr. SJOSTEDT. On 

 the other hand Dr. STADELMANN records 8 species of S-ynagris, a typical African wasp genus, of which 

 Dr. SJOSTEDT has only collected 1 species. Sceliphron is only represented by one common species as against 

 7 in Dr. STADELMANN'S list. I should have expected S. hemipterum F. to have been found, considering how 

 widely it is distributed. Also Polistes hebrceus F. The Honey-bee killing genus Philantims appears to be 

 a characteristic one. The spider-killers, the Pompilidce, the cricket-feeders, Sphex and, to a less extent, Noto- 

 f/onia, Tachytes & TacJiyspher are common. The Pompilidce (38 species, including one new genus) and the 

 Mutillidce of which the actual number of species is impossible to accurately reckon owing to our want of 

 knowledge of the relationship of the sexes, are the two predominent groups of the Fossores. Among the 

 noteworthy forms I have described are the new genus Schizagenia, the Pseudagenia odontocephala, the Tra- 

 chypus albolineatus (if it be truly identical with the American genus Tranlnjpus, or only an aberrant Pltilanthus) 

 and Meira rujitarsis. I have, in conclusion, to thank Dr. SJOSTEDT for the oppertunity of examining'and 

 reporting upon his very valuable collection.
