Superfamily Argiopoidea 



the base of a very deep notch in the terminal margin of the seg- 

 ment. 



Subfamily CLUBIONIN^E (Clu-bi-on-i'nae) 



In this and in the following subfamily the last segment of 

 the hind spinnerets is quite distinct and conical. In this sub- 

 family the labium is much longer than wide, and extends beyond 

 the middle of the endites. The endites are narrower at the middle 

 than at the apex, and are margined on the inside with incurved, 

 very long hairs. 



Only two genera are represented in our fauna. 



TABLE OF GENERA OF THE CLUBIONIN/E 



A. Posterior legs longer than the anterior legs; tibiae and meta- 

 tarsi of the first two pairs of legs armed beneath with 

 paired spines. P. 565. Clubiona 



AA. Anterior legs longer than the posterior legs; anterior legs 

 armed with but few spines, and these are not paired. P. 569.

Genus CLUBIONA (Clu-bi-o'na) 



The median furrow of the thorax is present. The posterior 

 eyes are equidistant or the median eyes are farther from each 

 other than from the lateral eyes. The lower margin of the furrow 

 of the chelicerae is usually armed with two teeth, but sometimes 

 with three, four or five. The posterior legs are longer than the 

 anterior. The tibiae and metatarsi of the first two pairs of legs 

 are armed beneath with paired spines; there are one or two 

 pairs, usually two, beneath the tibia, and a single pair beneath 

 the metatarsus of each of these legs. 



The spiders of this genus are of medium or of small size; 

 they are pale or tawny; the abdomen is clothed with white or 

 pale yellow pubescence, with a silky reflection; most of them are 

 without markings, but some have the abdomen ornamented either 

 with a median line or with a series of chevrons. 



These spiders live in silken tubes which they spin under bark 

 or stones or in rolled leaves; these tubes have two openings, and 

 adhere to the object to which they are attached. 



This is a very large genus; seventeen species arc known
