THE CURLED-THREAD WEAVERS. CINIFLONID.E. 



These spiders have been separated from the others, because the adhesive threads which they spin are 

 curly. They have in front of the usual spinnerets an additional spinning organ called the cribillittn and on 

 their hind feet a comb-like intrument a row of stiff spines called the calamistrum, which they use to 

 extract the threads from the cribcllnm. 



According to the way in which they make their webs, they are divided into two sub-families. 



1. The Dictynidic, otherwise like Tlicrididie or some Dmssidte (Amaurobius')., spin irregular webs 



covered with curly threads, on plants, flowers or walls, and watch them from some tube or crevice. 

 They are all very small spiders. 



2. The UloboriiUc build regularly planned webs. 



HYPTIOTES. 



The triangle spider. 



3. H. cavata. -' in. long. Blackish brown with white clots and lines and five pairs of warts 

 on its body part. Its legs and eyes are like Epcira ; the lower side eyes almost invisibly 

 small. It builds a triangular web. like a section of an orb-web of only four spokes. To be 

 found mostly on pine trees. 



ULOBORUS. 



U. pliiinipes. fV in. long. Brownish. Body part with black lines and two warts on forward 

 part. Legs with dark rings. The eyes are like Tctragnatha. The web resembles an orb- 

 web in shape, but is placed horizontally. The spider guards it from the under side, with his 

 legs extended in a straight line like Tctragnatlta. It builds in holes or hollow logs.
