Genus Synemosyna. Mihi. 



Characters. Cheliceres short in the females ; maxillce slightly 

 inclined toward the tip, truncated at tip ; lip short, rounded ; 

 eyes eight, unequal, in three rows, the first composed of four eyes^ 

 the two middle ones largest, the second composed of two small ones 

 placed nearer the first than the third, ivhich is composed of two 

 larger eyes ; feet slender, the fourth pair longest, the other three 

 variable; body elongated, nodose, abdomen contracted near the 

 middle. 



Habits. Araneides wandering after prey, making no web, 

 but silk tubes, for hibernation, running on plants like ants, 

 which they resemble ; cocoon. 



Remarks. This differs in many points from Myrmecia, 

 Latr., Ann. des Sc. Nat. iv. p. 261, and yet seems to be 

 closely related to it. That subdivision is not known to me, 

 though it is said in that work that some species are found in 

 Georgia. In Myrmecia the cheliceres are large, in this, they 

 are small, at least in the females ; in that subgenus the maxillre 

 are rounded and hairy, the abdomen is much shorter than the 

 cephalothorax, and they have other characters which do not 

 belons to this.
