SYNEMOSYNA HENTZII N. SP. 



PI. VII., Fig. 2, female. 

 9 . Total length, 5 mm. 



Cephalothorax : Length, 2 mm. ; width 1 mm. 



Legs, 4312 ; equally stout. 



1st leg longer than 2d b}^ tarsus. 



4th leg longer than 3d by tarsus and metatarsus. 



In shape this species is longer and slenderer than formica. 

 The cephalothorax is low, with two constrictions in the thoracic 

 part, one before the middle, and the other nearer the posterior 

 end; between the constrictions it is rounded, but not so widety 

 as in formica. The cephalic part slants forward. The anterior 

 row of eyes is a little curved ; the middle are two and a half 

 times as large as the lateral and the four eyes touch each other. 

 The falces are vertical, parallel and rather weak. The coxse of 

 the first pair are separated by the width of the lip. The lip is 

 a little wider than long. The abdomen is long and slender, 

 with a constriction just in front of the middle, and has the in- 

 tegument hardened at the anterior end both above and below. 

 It is not enlarged behind like the abdomen of formica. 



Color. The general color is light, the cephalothorax being- 

 reddish, with a black band running around the eyes, and the 

 abdomen yellow, having on the posterior segment a heavy, 

 curved, black band on each side, and a dark, longitudinal line 

 down the middle. The legs, palpi and under parts are all 

 yellow.
