metatarsi and tarsi which are pale yellow. At the union of 

 these two joints is a black ring, and the tarsi are tipped with 

 black. The palpi are pale brown in the female and dark 

 brown in the male, and are covered with white hairs. 



We have a number of males and females sent us from 

 Wallace, Kansas, by Mr. Papenhoe. 



ERIS C. KOCH. 

 Plate XVI., Figs. 12— 12e. 



The cephalothorax is high, and is plainly longer than wide. 

 Its greatest width is at the dorsal ej'es. The sides are widely 

 rounded out, both in the cephalic and thoracic part. 



The quadrangle of the eyes is one-third wider than long and 

 is very much wider behind than in front. It occupies from 

 one-half to three-fifths of the cephalothorax. The first row of 

 eyes is straight or a little curved. In the type species the eyes of 

 this row are all well separated, the lateral not more widely from 

 the middle than the middle from each other, and the middle 

 are less than twice as large as the lateral ; but in maculata the 

 middle eyes are sub-touching, and the lateral are a little 

 separated from them and only half as large. The second row is 

 half-way between the first and third, or is nearer the first. The 

 dorsal eyes are on the sides of the upper part of the cephalo- 

 thorax, but as the sides round out a little they form a row not 

 quite so wide as the cephalothorax at that place. 



We have included the genus Bianor Keys, in Eris. We 

 have in our collection the tj^pe, Eris albo-bimaculata Lucus 

 (for description see Simon's Arachnides de France, Vol. III., 

 p. 198) and Eris (Bianor) maculata Keys., from Sidney, de- 

 scribed as Scythropa maculata in Arachniden Australiens, 

 p. 1447.
