Superfamily Argiopoidea 



easily separated by the fact that in the clubionids the fore spin- 

 nerets are contiguous, while in the drassids they are widely 

 separated. 



The Clubionidae includes five subfamilies, all of which are 

 represented in our fauna. The first of these subfamilies, the 

 Anvphaeninae, is sharply distinguished from the others by the 

 position of the furrow of the posterior spiracle. In the case of 

 the other subfamilies the differences between them are such that 

 a key based upon them would not be as practicable for the de- 

 termination of specimens as a more artificial one, like the following: 



TABLE OF SUBFAMILIES OF THE CLUBIONID/E 



A. Furrow of the posterior spiracle remote from the spinnerets, 

 usually near the middle of the abdomen. P. 560. 



Anyph^enin^e 



AA. Furrow of the posterior spiracle situated near the spinnerets. 



B. Tibiae of the first two pairs of legs with a definite double 



series of long spines on the lower side, in which there 



are more than two spines in each row. P. 571. 



LlOCRANIN/t 



BB. Tibiae of the first two pairs of legs without a definite 

 double series of long, movable spines consisting of more 

 than two spines in each row. 

 C. First pair of legs not longer than the fourth pair; 

 legs either with or without spines. 

 D. Spines fairly numerous on the legs. 



E. Anterior median eyes scarcely the diameter of one 



of them from the front margin of the clypeus. 



F. Labium wider than long; cephalothorax mottled 



with brown. P. 571. Liocranin/e 



FF. Labium longer than wide; cephalothorax not 



mottled (Clubiona). P. 565 Cllbiomn.e 



EE. Anterior median eves several times the diameter 



of one of them from the front margin of the 



clypeus (Castianeira) . P. 577. Micariin.v 



DD. Legs not armed with spines or with only a few 



under the tibiae of the first pair. 



E. Median furrow of the thorax wanting or faintly 



indicated; endites slightly depressed in the 



middle (M icarid). P. 377. Mi< vriin/e
