spider and hang in the web near the nest. It is found in Europe in 

 plant-honses, and in South America and Australia. Its native coun- 

 try is unknown. 



Theridium rupicola, new. 



Plate II, figures 2 to 2c. 



This little species closely resembles T. tepidarioritm, the females 

 being easily mistaken for the young of that species. The females 

 are 2'5""" long and tne males 2'"'". The colors are as in tepUlario- 

 rum, though I have never seen such light individuals as in that spe- 

 cies, nor do the colors of the male diifer so much from the female, 

 the legs being only slightly more orange and showing the brown 

 rings distinctly. The abdomen has a pointed hump in the middle, 

 partly covered by the middle black spot and partly bright white. 

 The large lateral black spots have also white spots beliind them, and 

 sometimes the whole back part of the abdomen beliind the hump is 

 nearly white. The palpal organ differs plaiidy from tepidariorum. 

 The epigynum has a narrower opening on a ridge just in front of the 

 fold. 



This spicier lives under stones and among rocks where it builds 

 weT)s like those of tepidariorum, often containing grains of sand, 

 which look as though placed there [)urposely by the S[)ider.

Plate TI, figure 3. 



This little spider is about 2"'"' in length. The abdomen is some- 

 what flattened behind and 1 -5'"™ high, pointed toward the spinner- 

 ets. The hinder portion is white with a large spot in the middle, 

 below which, in my specimen, is a smaller black spot. The front up- 

 per part of the abdomen is yellowish gray and the under part brown. 

 The cephalothorax is orange brown, except the space between the eyes, 

 which is l)lack. The legs are also orange brown. The epigynum is 

 dark brown and very prominent. The opening appears to be in front 

 near the pedicel of the abdomen.

 His., vol. vi. 



Another specimen, from New Haven, Conn., had the front part of 

 the abdomen brown with a bright white line behind it over the back 

 and down both sides.
