110 PECKHAM. [Vol. 2, 



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

 is equally wide in front and behind or wider behind (usually 

 plainly wider behind) and occupies two-fifths of the cephalo- 

 thorax, or a little less. The first row of eyes is straight. The 

 middle eyes are close together, the lateral sometimes a little 

 separated. The middle are twice, or nearh^ twice, as large as 

 the lateral. The second row is half-way between the first and 

 third rows, or is a little nearer the first. The third row is as 

 wide, or very nearly as wide, as the cephalothorax at that place. 



In Pseudicius the cephalothorax is longer and narrower 

 than in Icius, and the cephalic part is not inclined. It differs 

 from Menemerus in being lower, flatter, narrower and not so 

 much dilated, and in having the cephalic part level and the 

 abdomen rather long and narrow. 



The type of Pseudicius is (Dendryphantes) encarpatus 

 AVlk., described in Simon's Arachnides de France, Vol. TIL, 

 p. 42. We include in this genus Attus binus Hentz, described 

 under the genus Menemerus by Mr. Emerton in his New Eng- 

 land Attidfe, Trans. Conn. Acad.,Vol. VIIL, Oct., 1891 ; Marptusa 

 radiata Grube, described by M. Simon in his Arachnides de 

 France, Vol. III., p. 28 ; two new species, oblongus, from Brazil, 

 and cognatus, from Japan, and Icius piraticus P., N. A. Attidse, 

 p. 49.

The cephalothorax is low and long ; it is narrowest in 

 front and widens gradually from that point to the anterior 

 thoracic part, where it is widest. The sides are nowhere verti- 

 cal. The upper surface is perfectly' flat through the cephalic 

 and two-thirds of the thoracic part, except for a slight depres- 

 sion that separates the two, and then falls in a short, gradual 

 slope to the margin. The upper surface of the thoi'ax is nar-
