The type of the subgenus Proterosphex thus established is 

 Sphex maxillosus Fab., as was designated for the subgenus 

 Sphcx by Kohl., as Proterosphex replaces that name. 



Throughout this investigation it has been a great satisfac- 

 tion to have had the active co-operation of Dr. W. H. Ash- 

 mead, and of Dr. C. W. Stiles, who is a member of the Commis- 

 sion on Nomenclature of the International Zoological Congress. 

 These gentlemen have gone over the whole subject thoroughly 

 and have fully endorsed the views herein presented, and the 

 writer desires to express his deep appreciation of their kindness. 



It may be added that the family name for this group of 

 insects should be Sphecidae rather than Sphegidse, the genitive 

 of Sphex being Sphecos, not Sphcgis. The correct formation 

 has already beeu indicated in the Century Dictionary.
