by 



P. CAMERON. 



The Fossorial Hymenoplera (Hutillidie, Tipliiidw and Sphegidce) collected by Prof. 

 Dr. SJOSTEDT (177 species, 146 new species, 862 specimens) form a very valuable addition 

 to our knowledge of the Hymenoptera inhabitating German East Tropical Africa (Massai 

 Land). Most of the species were taken on the Mountains Kilimandjaro and Mem. The 

 Geographical relations of the species I purpose discussing, along with the Spltegidce, at 

 the end of this paper.
