112 PECKHAM. [Vol. 2, 



in the central posterior part of the venter is a longitudinal black 

 band ; in the anterior part this band narrows and is bordered 

 with dull gold color. 



Of this species we have a single example, a female, from 

 Santarem, Brazil. 



PSEUDICIUS COGNATUS SP. NOV. 



Plate XI., Figs. 3— 3a. 



9 . Length, 8.4. Length of cephalothorax, 3.2 ; width 

 of cephalothorax, 2.2. 



Legs, 1432 ; the second and third not far from equal. 

 First pair plainly stoutest, and of a darker color 

 than the others. 



The whole spider is long and narrow. In the cephalic 

 part the cephalothorax is moderately high and the sides slant 

 inward toward the lower edge. There is a transverse depression 

 behind the dorsal eyes, behind which the thoracic part re- 

 mains on the same plane as the cephalic for about half its 

 length, and then slopes rather gradually to the posterior border. 

 The quadrangle of the eyes is one-third wider than long, is 

 wider behind than in front, and occupies two-fifths of the ce- 

 phalothorax. The first row of eyes is straight, the middle eyes of 

 this row are close together and are fully twice as large as the 

 lateral eyes, which are a little separated from them and are placed 

 further back. The second row is half-way between the first and 

 third. The third row is as wide as the cephalothorax at that 

 place. The whole cephalothorax is long and narrow, the nar- 

 rowest point being at the anterior end, from which place it 

 widens gradually to near the po.sterior end. 



The abdomen is long and narrow, and is slightly wider in 

 front than behind. 



The first leg has the femur, patella and tibia enlarged. 

 There are two rows of spines on the under side of the tibia and 

 metatarsus, those of the outer row being much smaller and 

 weaker than those of the inner. The falces are vertical, and 

 are long and strong.
