out a little throughout their length, especially in the thoracic 

 part. The cephalothorax is wider than the third row of eyes. 

 The quadrangle of the eyes is a little wider in front than 

 behind. The dorsal eyes are large and prominent. 



The falces are vertical, weak and moderately long. The 

 clypeus is about one-third as high as the middle eyes of the 

 first row. 



The cephalothorax is reddish-brown, darkest in the cephalic 

 region, with a black rim around the margin. Our specimen is 

 rubbed, but there seems to have been a covering of white and 

 reddish-yellow hairs over both cephalic and thoracic parts. 

 There are some long red hairs over the first row of eyes. The 

 integument of the abdomen is of a pale yellowish-brown color 

 with a covering of short white hairs. On the back is a pattern 

 of dark brown markings, which are shown in the figure, and 

 which come out more distinctly under alcohol than when the 

 spider is dry. The legs and palpi are reddish-brown with 

 darker bands. 



We have a single female from Central America, exact 

 locality unknown.

The cephalothorax falls in a rounded slope, in botli direc- 

 tions, from the dorsal eyes, the thoracic part sloping more 

 steeply in the second half. The widest point is in the middle 

 of the thoracic part, there being a slight gradual contraction 

 from this point forward to the first row of eyes. The sides 

 slant outward, especially in the thoracic part. 



The quadrangle of the eyes is wider in front than behind, 

 is one-third wider than long, and occupies two-fifths of the 

 cephalothorax. The second row of eyes is nearer the third
