Araneides of the United States. 455 
Remarks. This sub-genus, very closely related to CLusiona, 
is very well characterized notwithstanding the similarity. The 
character derived from the respective length of the legs is 
very constant, showing the property of being fast runners in 
all the species of this division. 
In habits they differ wholly from Crvsrowa, being in fact 
wandering Araneides. "The swiftness with which they run is 
truly surprising. They are not exclusively nocturnal, being 
often seen to run in the brightest sunshine. 
Tribe I. Brevirepes. Legs strong, rather short, maxilla 
long, cut obliquely above.

Sreat rapidity on paths and frequented places. It is diurnal,
