less than twice as long as the labium. The first leg has the 

 femur very broad, and the tibia and metatarsus with a double 

 row of stout spines. 



This is the largest species of Rudra that we have, and the 

 abdomen is not so flat as is usual in this genus. The cephalo- 

 thorax is glossy reddish-brown, with a dark band around the 

 sides, a dark central line over the thoracic part, a black line 

 around the margin and black spots around the eyes. The 

 marks on the abdomen recall those of Rudra geniculata, which 

 is also from Guatemala. The lower sides are dark brown ; the 

 upper surface is pale, with a pattern of brown lines, one longi- 

 tudinal, one down the middle, a wavy one on each side of this, 

 and two or three chevrons in the posterior half. The clypeus 

 is covered with white hairs. The first legs, palpi and falces 

 are dark brown ; the other legs are pale. 



We have one female, from Guatemala.

9 . Length, 5. Length of cephalothorax, 2 ; width of 

 cephalothorax, 1.4. 



Legs, 1423 ; those of the first pair very much the longest 

 and stoutest. 



The cephalothorax is verj'low, and, excepting that there is 

 a depression in the middle of the thorax, is perfectly flat 

 throughout its entire length. The sides are vertical in front, 

 but widen out a little behind the dorsal eyes. The eyes of the 

 first row are close together in a straight line. The middle are 

 not quite twice as large as the lateral. The second row is a little 

 nearer to the first than to the third row. The third row is 

 very nearly as wide as the cephalothorax at that place. The 

 clypeus is so narrow as to be indistinguishable. The falces are 

 very short and small, and are directed backward. The palpi 

 are long and slender. The labium is longer than wide. The 

 maxillse are truncated, and are less than twice as long as the 

 labium. The abdomen is flattened. The first legs are much 

 enlarged, the other three pairs being equally stout. The femur
