(Plate XIX.) 



"While engaged in incorporating accessions and rearranging the 

 collection of the Pompilidce and other Fossorial Hymenoptera in 

 the Museum of Natural History at South Kensington, I have 

 found a number of species which, so far as I can make out, have 

 not previously been described. In the classification of tlie 

 Pompilidce I have in this paper followed Kohl. His " Die 

 Gattungen der Pompiliden," published in the Verhandlungen 

 der k.-k. zoologisch-botanischen Gesellschaft in Wien, 1884, 

 contains by far the best arrangement of the genera of that very 

 difficult and puzzling family.
