Beata is easily distinguished from Homalattus, Rhene 

 and Anamosa by the shorter cephalic part, and from Ballus by 

 its widely rounded sides. It is represented, in our collection, 

 by a new species from New Grenada. 



BEATA MAGNA SP. NOV. 



Plate XV., Figs. 9— 9c. 



9. Length, 5.5. Length of cephalothorax, 2.5 ; width of 

 cephalothorax, 2.5. 



Legs, 1432; tirstpair stoutest, with tibia enlarged. 



The cephalothorax is brown, covered with brownish- white 

 hairs, which grow long on the sides and around the eyes. The 

 abdomen is brown, with a tliin covering of whitish hairs, there 

 being a fringe of them at the anterior end. On the dorsum are 

 some pairs of spots and wav}^ lines in pure white, and toward 

 the posterior end are two chevrons. 



The legs are banded witii lighter and darker brown. In 

 the first pair the general color is darker than in the others, 

 but the patella and the proximal end of the tibia are covered 

 with pure white scales, while the distal three-fourths of the 

 tibia is dead black, without scales. 



We have four females from New Grenada. 



COCCORCHESTES THORELL. 



Very small spiders, resembling beetles. 



The cephalothorax is high, and almost as wide as long. 

 The upper surface slants upward from the first row of eyes to 

 the posterior end. The sides slant inward from the upper sur- 

 face ; they are almost parallel, the cephalothorax being a very 

 little wider at the posterior end. 



The abdomen has a rounded outline, and is about as wide 

 as long. The cephalothorax and abdomen are formed to fit 

 closely together. In some cases the posterior end of the cephalo- 

 thorax is hollowed out and overlaps the anterior end of the 

 abdomen, while in others the case is reversed, the anterior end 

 of the abdomen being excavated to receive the posterior end of
