No. 1.1 ANT-LIKE SPIDERS OF THE FAMILY ATTID.E. 35 



Legs, 4312 ; equally stout. 

 The cephalic part is high and is separated from the 

 thoracic by a constriction ; the thoracic part is lower, but not 

 nearly so much lower as in plataleoides, and narrows a little 

 behind. The quadrangle of the eyes is one-fourth wider than 

 long, a little wider behind than in front, and occupies a little 

 more than one-third of the cephalothorax. The first row of 

 eyes is a little bent downward ; the eyes are all close together ; 

 the middle being about twice as large as the lateral. The 

 second row is plainly nearer the first than the third row. The 

 dorsal eyes are larger than the lateral and are placed on the 

 side of the cephalothorax. The pedicle is very long, and is 

 bi-articulate. The falces, in the male, are long, horizontal, and 

 flattened above, and are slightly wider in the middle than at 

 ■either end ; from below, four or five teeth are visible on the 

 inner edge of each falx ; the fang is nearly as long as the falx. 

 In the female the falces are short and stout and a little oblique. 

 The sternum is very narrow, and the lip is much longer than 

 wide. The abdomen is long and oval, with a deep constriction 

 in the anterior third. 



Color. This is a large, dark species. The male has the 

 cephalic part very dark and slightly iridescent, with some short, 

 white hairs in the anterior part, which are directed forward on 

 the sides, and obliquely upward and forward on the upper part ; 

 between the cephalic and thoracic parts, in the constriction, is a 

 iDand of white hairs; the thoracic part and the pedicle are 

 medium brown in color. The abdomen is divided into two 

 parts by a constriction ; the anterior part is dark brown, shad- 

 ing into blackish ; the posterior is black and is thinly covered 

 with white hairs, which vary in length, some being long and 

 some short. The upper, flattened surface of the falces is rugose 

 and is medium brown in color, excepting in the central inner 

 region, where it is dark and somewhat iridescent. The legs of 

 the second pair are light brown ; the others are dark brown 

 at the proximal ends and shade to medium brown at the tips. 

 The palpi are medium brown. On the venter, in front of the 

 ■constriction, is a transverse band of yellowish-white hairs.
