other pairs, one pair near tlie front end of tlie alxlomon and another 

 smaller on the sides half way back. The body of a fidl grown 

 female is about Y""" long, and the distance between the tips of the 

 spines is equal to the length of the body. The legs and cephalotho- 

 rax are yellowish brown, the latter with whitish edges. Underneath, 

 the abdomen is strongly wrinkled and marked wMth black bands and 

 yellow spots. The posterior spines are lighter on the under side. 

 The young differ greatly from the adult female. The abdomen is 

 longer than wide. The posterior spines are short and blunt and the 

 general color of the body is dark brown. There are two light spots 

 just in front of the base of the spines and other smaller ones on vari- 

 ous parts of the abdomen. The two hinder pairs of legs are whitish 

 with longitudinal dark stripes. The first and second pairs are dark 

 toward the base and white at the tips. 



The males resemble the young. They are about 4'^"" long. The 

 abdomen is long and \videst behind and truncate without any spines 

 except slight humps. On each side of the abdomen are three black 

 spots in which are slight humps. Across the hinder part of the 

 abdomen are four light spots as in the young. The cephalothorax is 

 dark brown and the legs liglit yellow with dark markings as in the 

 young. 



They become adult the last of Jidy and are found till October. 

 They are common in Massachusetts and Connecticut. The webs are 

 usually in low bushes and the adult females seem to hang all the 

 time in the webs. '

This is a much smaller species than spinea, measuring 4 or 5™'" 

 long. The abdomen of the female extends forward so as to cover 

 half the cephalothorax. It is three-fourths as wide as long and 

 ' square at the hinder end where it has two pairs of spines. The abdo- 

 men is white or yellow above. There is a dark spot of variable size 

 and shape over the first segment and a dark middle stripe between 

 the hinder spines. There are also numerous black muscular spots. 

 Below the abdomen is wrinkled and marked with black and yellow 

 very much as in spinea. The cephalothorax and legs are brownish 

 yellow. The cephalothorax is shorter than in spinea, the front of the 

 head square and the sternum nearly circular. 



Common at New {laven, Conn. I have not found it in Eastern 

 Massachusetts nor farther north.
