which it is closely allied structurally. It is found in houses, upon walls, 



etc., in warm situations. It is described as slow and deliberate in its 



motions, displaying somewhat of the action of a gnat in lifting

 acter of the aranead is mild and quiet. The poison fangs are 

 so feeble as to be of but little use in seizing its prey, which office is chiellv 

 performed by the maxilla;. When taken, Scytodes offers no resistance and 

 attempts no flight, but, feigning death, resigns itself quietly to its fate. 1 



This tribe embraces the singular genus Walckenaera, some of whose 

 species have the eyes placed upon little turret like elevations of the ceph- 

 alothorax. Their habits have not been carefully studied, and 

 their cocoons are little known. One European species, Walcke- 

 naera acuminata, makes a cocoon Hat on one side, rounded on the 

 other, about one-third inch in diameter, and composed of slightly woven 

 white silk. It is found in autumn on the under surface of stones and

 resentatives of this strange genus, which are relegated by Emerton to vari- 

 ous genera, 3 and it is probable that their cocoonery nearly resembles that 

 of the above species.

The most common Tubeweaver in the Eastern States is probably the 

 Speckled Agalena, Agalena nsevia. Its funnel shaped nest, with its broad 

 sheeted top spread over the grass or hedges, or stretched in mis- 

 cellaneous sites, is one of the most familiar objects in our land- 

 scape. Its cocoon is attached to some surface, as the leaf of a 

 tree, a rock, or the under surface of a loose bit of old bark. In 

 this position Agalena spreads a circular patch a half inch or 

 more in diameter, within which she encloses her eggs. This is covered
