50 PECKIIAM. [Vol. 3. 



cephalic plate is level from the dorsal e3'es to just above the 

 anterior eyes, and is then inclined forward, while the thoracic 

 part rounds off abruptly from the dorsal eyes, and then falls 

 still more steeply in the posterior half. In capitatus the thorax 

 is level for some distance behind the dorsal eyes, and in liondu- 

 rensis it falls very gradually. The falces are vertical and 

 moderatel}'- long and stout. 



The color of the cephalothorax is dark brown, pretty well 

 covered with yellowish gray hairs, which grow long and thick 

 on the clypeus. The abdomen seems to have been covered 

 with short white hairs, but as our specimens are rubbed nearly 

 bare, it is impossible to say what the original appearance of the 

 spider was. The integument is of a pale brownish color. On 

 the dorsum are four pairs of dark spots. The first pair is close 

 to the second, and the two spots are connected by a dark band 

 which runs across the front of the abdomen. In the pale space 

 thus marked off, are four black dots. On the posterior part of 

 the dorsum the dark spots are connected with a dark marking 

 down the middle, so that there are alternating pale and dark 

 wavy bands. The palpi are light brown, with gray hairs. 

 The femur, patella and tibia of the first leg are dark brown, 

 deepening to black on the sides, the femur having a pale 

 space underneath. They are thinly covered with white hairs. 

 The metatarsus and tarsus are yellow. The femoral joints 

 of the other legs are pale. That of the second has a large 

 dark spot on each side at the extremity, while those of the 

 third and fourth have a dark band. The legs are otherwise 

 yellow, with dark rings at the ends of the joints. The falces 

 are dark reddish-brown. 



We have one male and five females from Panama.
