A common species in the Islands, and, according to Mr. 
Blackburn, provisions its nest with spiders. The var. 
flavipes Fab. see. Saussure and var. limatus Fab. sec. 
Sauss. (c/. 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 metonotum being nearly all yellow. The species 
has a wide range in North America, but does not, I 
think, extend further south than Mexico.
