Sphecodes, Latr. 

 By T. D. A. Cockerell. 

 Of the genus Sphecodes in the broad sense, sixteen species are known 

 from the Eastern and Middle States, nine from the Rocky Mountain 

 region, seven from Mexico, three from the West Indies, and only three 

 have been recorded from the States bordering on the Pacific. The 

 Pacific species are probably numerous, but mostly unknown ; in the 

 present article six are reported from Olympia, Washington State,* where 

 they were collected by Professor Trevor Kincaid. 



*It would save much confusion if the State of Washington could be known as 

 Washingtonia, with the abbreviation Washa. or Wa.
