Family OONOPID^. 



On the authority of Nathan Banks, this family is given a rep- 

 resentative — Orchestina — in our spider fauna. The cocoons are, 

 in general, of a similar type, each consisting of a roundish bit of 

 white floss covering a small number of eggs — only two in Oonops 

 pulcher. There may be several cocoons, however, for each spider. 



Family OXYOPID.a:. 



This family is best known by the genus Pucetia, from the 

 Southern states and California. Its two representative species, 

 P. aurora and P. viridans, suspend their cocoons in a little ir- 

 regular web stretched for that purpose among leaves and 

 branches. The cocoon is conical, and has little, rough, di- 

 verging points, which serve for attachment to the suspending 

 threads. It has no flossy packing, and is made up of a single 

 piece ; that is, it has no suture. Hentz speaks of P. viridans as 

 watching over her cocoon constantly. In the genus Ozyopes the 

 cocoon differs much from that of Pucetia. It is discoid, very 

 flat, and firmly attached, like that of PJiilodromus , in the family 

 Thomisidic. 



Family PHOLCID.ffi. 



The Long-legged cellar spider, Pholcus phalangiodes, is our 

 most common representative. Members of the family in gen- 

 eral make no containing sack for the eggs that could properly 

 be called a cocoon. The eggs are simply held together in the 

 form of a small, rounded mass by a few threads of silk. This 

 little ball of animate possibilities is carried about by the female 

 in her chelicerae and pedipalps until the young are hatched and 

 ready to disperse. The number of eggs is never very large, 

 usually not more than five or six. A foreign species described 

 by Simon carries only two eggs, which, however, are of un- 

 usual size. In other foreign species the eggs are brightly 

 colored in shades of violet, brown, and green. 



Type: Pholcus phalangiodes. 



This spider may be found in cellars, hanging back downward 

 from the threads of its irregular web. Two females carrying 

 cocoons were taken in a cellar used for storing bananas, Sep- 

 tember 16. Hentz reports them as cocooning earlier, giving 

 several dates in July when he observed them with their egg-
