I. elegans is found in Maine, New Hampshire, Massachusetts, 
New York (Mr. Banks has it from Long Island), Florida, Illi¬ 
nois, Wisconsin and Nebraska. In Wisconsin it matures about 
July 10, and for from ten days to two weeks it is very common.

This is a dark spider, and looks very much like an ant. 
The cephalothorax and abdomen are dark with iridiscent 
greenish scales. There is a white marginal band on the thorax. 
The legs are black with white stripes, two on the sides and 
one below. The palpus is dark with a white line within and an 
indistinct light line on the outside. 
The sides of the cephalothorax are nearly parallel, and both 
cephalothorax and abdomen are more rounded than is usual. 
Mr. Emerton had only the female, from Connecticut and
