164 PECKHAM. [Vol. 2, 



The female is medium brown in color, thickly covered 

 witli short, yellowish-white hairs. Our only male is of a much 

 darker brown, and has had the hairs nearly all rubbed off. The 

 first legs are brown, excepting the metatarsus and tarsus, 

 which are pale, with a dark line running along the inner side ; 

 the other legs are pale with dark rings at the joints. In the 

 fourth leg these rings are joined by a dark band, which runs 

 along the upper surface. 



We have several females and one male from Para and San- 

 tarem in the Smith collection. 



The small size of R. vaga and the position of the second 

 row of eyes distinguish it from other species. 



ANAMOSA GEN. NOV. 



The spiders of this genus are decidedly larger than in Rhene 

 and Homalattus. The cephalothorax is rather high and its 

 upper surface is slightly convex. The thoracic part remains 

 on the same plane as the cephalic for a ver}' short distance be- 

 hind the dorsal eyes and then drops abruptly, the posterior part 

 being overlapped by the abdomen. The widest point is at the 

 dorsal eyes. The sides are vertical or nearly so. The cephalo- 

 thorax is wider than long. 



The quadrangle of the eyes is plainlj' wider behind than 

 in front, and is about one-third wider than long. It occupies 

 fully two-thirds of the cephalothorax. The eyes of the first 

 row, which is straight, are all plainly separated, the lateral 

 more widely than the middle. The middle eyes are nearly 

 twice as large as the lateral. The second row is much nearer 

 the first than the third row. The third row is as wide, or nearly 

 as wide, as the cephalothorax at that place. 



The relative length of the legs is 14 23. 



The type of this genus is callosa, a new species from the 

 Himalaya Mountains. We have one other new species, incon- 

 cinna, from Trinidad. As has been already stated, we believe 

 that Anamosa will also include two species of Thorell, Homalat- 

 tus margarops and Homalattus hirsutus, Ragni Malesi e 

 Papuani, I., p. 629 and p. 632.
