No. 2.] SPIDEIiS OF THE MARPTUSA GROUP. 101 



Taczanowski (Araneides du Perou, p. 220), which we have from 

 Amable Maria, and Marptusa bracteata L. Koch, from Aus- 

 traha (Arachniden Australieiis, p. 1105), which agrees closely 

 with the other species.

The quadrangle of the eyes is barely one-fourth wider than 

 long ; it is about equally wide in front and behind, and occupies 

 a little more than two-fifths of the cephalothorax. The second 

 row of eyes is nearer the first than the third. The third row 

 is not so wide as the ceph ilothorax at that place. The cephalo- 

 thorax is rounded on the sides and behind. The cephalic and 

 thoracic parts are on the same plane. The falces are vertical, 

 moderately stout and rounded. 



This is a rather large species. The first legs are moder- 

 ately long and are a little the stoutest, but are not so decidedly 

 thickened as in Balmaceda punctata. The abdomen is more 

 slender than the cephalothorax. 



The general color is lightish brown. The cephalothorax is 

 dark brown on the sides, with the central region reddish. There 

 is a white band around the lower margin, a central white spot on 

 the posterior thoracic slope, and some white hairs above on the 

 cephalic part, and around the anterior eyes. The abdomen 

 has the anterior half white or light brown on the sides and 

 dark brown in the center, while the posterior half is dark 

 brown with a herring-bone stripe in white or light brown down 

 the middle. The legs are light brown with darker rings at the 

 joints. The palpi are light and the falces dark brown. 



We have two males and one female from Guatemala 

 (east coast).
