No. 1.] ATTIDyE OF CENTRAL AMERICA. 19 



front of the middle. This central part and the lower sides 

 seem' to have been originally covered with white hairs. Low 

 down across the front end of the abdomen is a narrow dark 

 band, and above this there is a curved white band. The first 

 and second legs of the male are usually darkened, excepting the 

 proximal end of the femoral joints ; these, with the other legs 

 and the palpi, are of a light yellowish color. One male, from 

 Guatemala, is much darker than the others. 



The females are much like the males, although the color is 

 decidedly lighter. Some of them have red and some white 

 hairs on the cephalothorax, but none of them have the upright 

 ridge over the e3'es. The abdomen has a white line down the 

 middle, and has the innfer edges of the dark wavy bands edged 

 with white dashes and spots. 



This species was described as Triplolemus henignus in Pro- 

 ceedings of the Nat. Hist. Society of Wisconsin, December, 

 1885. 



We have three males and five females from Panama, and 

 one male from Gautemala, near Ysobol.

The quadrangle of the eyes occupies more than one-half 

 of the cephalothorax, and is equally wide in front and behind. 

 The middle eyes of the first row are more than twice as large as 

 the lateral eyes. The first row is plainly curved. The second 

 row is nearer the first than the third. The third row is nar- 

 rower than the cephalothorax. The clypeus is somewhat 

 higher than the large middle eyes. The falces project a little. 

 They are long and slightly divergent, with a tooth on the inner 

 side near the distal end. The fang is short. The palpus is as 

 long as the femur, patella and tibia of the first leg, having its 

 own tibia a little longer than the tarsus, while the patella is
