94 THE CANADIAN ENTOMOLOGIST. 



Family lo, Prodidomidce. 



We have but one genus and species in the Southern States. 



Family ii; Drassid(z. 



This embraces a number of common spiders. The body is low and 

 flat, the legs short and stout, the spinnerets usually projecting behind. 

 They spin no web but lead a wandering life in search of prey, mostly at 

 night. There are two sub-families. 



{ A dorsal groove present Drassince. 



\ No dorsal groove present Micariim. 



The latter group is represented by Micaria which is quite rare. 

 The Drassince. may be divided into two tribes. 



\ Hind row of eyes recurved Gnaphosi. 



I Hind row of eyes straight or procurved Drassi. 



The former includes Gnaphosa, Foeciiochroa and Pythonissa. The 

 latter includes Echemus, Drassus, Prosthesima and Temitiius. 



Family 12, Chibionidce. 



Closely related to the preceding family, they are usually light coloured, 

 while the Drassidce are dark. 



The legs are a little longer and more slender, the spinnerets less 



prominent, and the abdomen more round. It may be divided into three 



sub-families.

( A stiff, horny shield either on dorsum or around the base of the

(_ Abdomen wholly soft , Clubionince 



The latter sub-family may be divided into two tribes. 



j Two rows of very strong spines under tibiae I. and \\....Phrwolithi 

 (Tibiae I. and H. not strongly armed Clubioni 



Family 13, Agalenidce. 



Not a very extensive family ; most numerous in the west. The pars 

 cephalica here is very distinct, and occupies the whole width of the 

 cephalothorax in front. One genus, Cybaeus, disagrees with the characters 

 of the family, as the spinnerets are all short ; the genus will, however, be 

 readily recognized as belonging to the family because of its general resem- 

 blance to other more common forms. Two well marked sub-families 

 can be recognized.
