Plate XCI. 



In the following paper an attempt has been made to bring 

 together all the species of the cosmopohtan genus Odynerus 

 known to occur in the Ethiopian Region. Species from 

 Madagascar are not included. At the same time I have 

 taken the opportunity of describing a number of new 

 species and varieties. 



The genus would seem to be richly represented through- 

 out the whole continent, and the number of species must 

 ultimately prove to be very considerable. 



I have listed 132 species, and of these 24 are described 

 as new; three new varieties of known species are also 

 described. 



Through the courtesy of various correspondents it has 

 been possible to examine types or at least cotypes of a 

 number of the species. For these facilities my thanks are 

 specially due to the following : to Dr. Severin, of the 

 Musee d'Histoire Naturelle, Brussels; to M. Lucien 

 Berland of the Paris Museum; to Prof. Y. Sjostedt of 

 Stockholm and to Prof. E. B. Poulton, F.R.S., each of 

 whom has most generously loaned me types or cotypes from 

 their several institutions. All measurements of length 

 (unless stated to the contrary) are taken from the front of 

 the head to the apex of tergite 2. The types of all the 

 new species are in the British Museum.
