5. THERIDION STUDIOSUM. 
Plate IX. Fig. 5. 
Description. Greenish brown ; abdomen above with two 
scalloped yellowish lines, beneath with some yellow spots; 
feet with greenish rings; feet ; 75 4. ; 
Observations. This spider makes its web on bushes like 
Linyphia, frequently on a bush of dead leaves; it is hori- 
zontal and closely woven like that of Agelena, and is sur- 
mounted by threads crossed in every direction, but there are 
none underneath. This species has great affinity to Liny- 
phia. It does not remain in an inverted position under the 
horizontal web, but abides in the middle like other species of 
Theridion, and, in the same manner as some species of Epeira, 
it brings together a few leaves as a shelter. When its web is 
destroyed, it does not abandon its cocoon, which is orbicular 
and whitish, and is placed in the central part of the web. 
The mother then grasps it with her cheliceres, and defends 
her progeny while life endures. She also takes care of her 
young, making a tent like that of social caterpillars for their 
shelter, and remaining near them till they can protect them- 
_ Selves. This spider is very sedentary and little. inclined to 
move; always of small stature. TUM A Bey b
