around the lower sides. In some cases the central band on the 

 abdomen is broken into chevrons, as is shown in the drawing. 

 There are some stiff, black bristles in the eye region. The ven- 

 ter is evenly, but not thickly, clothed with Avhite hairs, and there 

 are also white hairs on the sternum. The legs and palpi are 

 light yellow. The falces are dark brown. 



We have three females of this species from Santarem,. 

 Brazil. 



ADMESTINA PECKHAM. 

 Plate XL, Figs. 6—66. 



Small spiders, with the cephalothorax narrow in front and 

 rounding out widely in the thoracic part. First leg with femur 

 and tibia thickened. 



The cephalothorax is low and flat, widest opposite the mid- 

 dle of the thoracic part, more contracted in front than behind, 

 and a little less than twice as long as wide. In front the sides 

 are vertical, while behind they are rounded. The quadrangle 

 of the eyes is nearly twice as wide as long, is a very little wider 

 behind than in front, and occupies one-third of the length of 

 the cephalothorax. The anterior row of eyes is curved ; they 

 are all close together, and the middle are twice as large as the 

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

 The dorsal eyes are a little larger than the lateral, and are 

 plainly further from each other than from the lateral borders ; 

 they form a row which is as wide as the cephalothorax at that 

 place. The labium is as wide as long. The abdomen is narrow 

 and rather long. 



While Admestina bears some resemblance to Hyctia, Hel- 

 vetia and Spadera it is smaller and not so slender. As it is 

 found only in the United States, it is not likely to be confused 

 with other genera. 



RUDRA PECKHAM. 

 Plate XII., Figs. 3—36. 



Spiders of medium size, or smaller. 



General appearance broad, low and flat, both in cephalo- 

 thorax and abdomen. First legs dark colored, elongated and 

 thickened.
