No. 1.] ATTIDJS OF CENTRAL AMERICA. 75 



two longitudinal, curved reddish-brown bands on the dorsum. 

 The palpus has the patella and tibia white and the tarsus red- 

 dish with long reddish-yellow hairs, which are sometimes 

 mingled with long white hairs. The legs are brown, those of 

 the first and second pairs being darker than the others, with 

 some short white hairs. The first leg has, in one example, a 

 pale patch on the upper surface of the patella, while another 

 has a blackish streak along the anterior face as far as the end 

 of the tibia. The falces are bright reddish-brown with some 

 long white hairs on their front face. When the spider is dry, 

 short yellow hairs appear on the cephalothorax above the 

 white bands ; the abdomen is seen to be covered with hairs, 

 the bands being of a rich reddish color which contrasts with 

 the pure white background ; and each of the bands has, in 

 front, on the inner side, a yellowish lozenge-shaped spot with- 

 out hairs, which makes the central white band considerably 

 narrower at tlie anterior end. Low down on the front part of 

 the abdomen is a short wide dark brown band extending only 

 across the front surface. In one example the red hairs are 

 rubbed from the bands on the abdomen, leaving them dark 

 brown covered with small yellow speckles. 



We have two males from New Grenada, sent to us by 

 Count Keyserling, and one from Guatemala in our own collec- 

 tion. 



MENEMERUS BICOLOR, SP. NOV. 



S . Length, 5.8. Length of cephalothorax, 2.5 ; width of 

 cephalothorax, 2. 

 Legs, 1432 ; first pair but little stouter than the others. 



A graceful, medium-sized species, the abdomen marked 

 with red and white. 



Although we put this species into Menemerus it does not 

 conform very closely to the characteristics of that genus. The 

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

 one-sixth wider than long, and occupies very nearly one-half of 

 the cephalothorax. The anterior eyes are in a curved row and
