covering a small, circular hole through which the young escape. 

 The pedicle itself usually hangs suspended from two or three 

 cross lines of silk attached to surrounding objects. From some 

 cocoons collected August 23 the young spiders emerged August 

 28. Data respecting the eggs are not at hand. 



Type: Tetragnatha extensa. 



This spider is abundant in the prairie regions. It does not 

 seem to have the preference for living near water shown by 

 other species of the genus, as it is found on the higher hills as 

 well as along the streams. The cocooning season is early in 

 the year, the species being one of the first orb-weavers to ap- 

 pear in the spring. In the month of May the interesting little 

 cocoons can be found swung by their supporting lines from 

 some convenient object. They are about the size and shape of 

 a cherry-pit — aproximately one-fourth inch in diameter. Each 

 is composed of loose material of a greenish tinge and is covered 

 with projecting tufts of whitish silk. The suspending lines, 

 usually three in number and about an inch in length, support 

 the cocoon like a hammock. They are stretched so tight as to 

 be nearly horizontal. The eggs are agglutinated into a little 

 ball looking like a tiny berry. They are whitish, tinged with 

 brown, and number about sixty. In some cocoons young spiders 

 were found May 20. 



Type: Argiope aurantia. 



The Golden garden spider spins its snare in about the same 

 situations as those chosen by Araneus trifolium. Its cocoons 

 are easily found in autumn among the goldenrods in or near 

 some marshy place, or down in the matted grass of the marsh 

 itself. They are large, bladder-shaped sacks, a little more than 

 one inch in longest diameter, and having a narrowed neck, to 

 the flaring top of which attachment is made with the lines 

 that support them. They are also held in place by a maze of 

 radiating threads which draw together the leaves and stems of 

 the supporting plant in such a way as to hide and protect the 

 cocoon. The exterior of the cocoon is light brown to dark 

 brown in color, and paper-like in texture. The egg-mass within 

 is again enclosed in a capsule of firm brown tissue, elongate- 

 dome-shaped, with base of dome upward, slightly convex,
