234 MESSRS. T. BLACKBURN AND P. CAMERON ON THE 



Mr. Blackburn^ provisions its nest with spiders. The 

 var. flavipes, ¥ah., sec. Saussure, and var. limatus, Fab,^ 

 sec. Sauss. {cf. Hymen, der Novara Reise^ p. 30), both 

 occur, the latter being distinguished from the former by 

 the greater extension of the yellow on the thorax, the 

 metanotum being nearly all yellow. The species has a 

 wide range in North America, but does not, I think, 

 extend further south than Mexico.
