The male, when fresh, has the entire body, in the middle, 
black, and snow-white stripes on each side, from the end of the 
abdomen to the end of the palpi. Sides of cephalothorax pale, 
lower margin edged with black; sides of abdomen darkish, 
falces dark brown, coxse and venter yellowish. First pair of legs 
much the stoutest and dark brown, other legs yellow. 
The female is much like the male but lighter in color; the 
central band on the abdomen is dark brown, the sides lighter, 
but not white. 
In some males there are three pairs of white bars running 
into the middle black band of the abdomen; the bars point for¬ 
ward. Possibly these bars are always present unless rubbed off. 
The species is easily distinguished, as the abdomen is more 
than three times as long as wide. Pobusta, its first cousin, is 
not found in the eastern or middle states, having been reported, 
so far, only from Arizona and California. 
The species ranges through Hew York, Pennsylvania, Mas¬ 
sachusetts, Kansas, Nebraska, Hew Mexico, Florida, South Car¬ 
olina, Georgia.
