THE CANADIAN ENTOMOLOGIST. 93 



Division II. — Microgiiathce. 



With but one section. 



Section II. — This includes spiders of the most primitive and com- 

 prehensive form 3 " prophetic types " as the older naturalists would call 

 them. They have a roundish cephalothorax which projects in front of the 

 small pars cephalica. The maxillae closely surround the lip. The 

 mandibles are small. The legs are usually long and slender, and they 

 make irregular webs. 



Family 5, Filistaiidce. 



These are the lowest spiders. The pars cephalica is no larger than 

 the eye-tubercle of Fhalangida with which it is homologous. The male 

 palpal organ is the most simple, only a tube at the end of the tarsus. 

 Filistata occurs in the southern parts of our countr)'. 



Family 6, Urocteidce. 



This family is represented by one species of TJialamia in the Southern 

 States. 



Family 7, Scytodidce. 



This distinct group is represented by two genera, somewhat rare in 

 the Southern States. 



Family 8, PholcidcB. 



Here the legs are long and slender, the tarsus in the typical forms 

 being furnished with an eighth joint. The forms are principally southern. 

 I include in this family Pholciis, Spermophora and Spintharus. 



Division III. — Verce. 



Here we come to the typical and more common spiders. It embraces 

 three sections. 



Section III. — This is about the same as the Tubitelaritz of certain 

 writers. The cephalothorax is usually low and elongate. The abdomen 

 also is commonly elongate and low. The legs fitted for running. The 

 eyes are equal in size and plainly in two rows. 



Family 9, Dysderidce. 



These have but six eyes • just behind the lung-slits is a pair of 

 stigmata. The forms are uncommon.
