AttUS palustris, Peckliam. 



Female 6"'"' long, male 5""". The cephalothorax is three-fourths 

 as wide as long. The abdomen is short, a little wider than the 

 cephalothorax and pointed behind. PI. XX, tig. ;5. The cei)halo- 

 thorax is light brown in the female and dark in the male, with a 

 narrow, white stripe in the middle, widened between the dorsal eyes, 

 and a white stripe each side, as high as the dorsal ej^es. The al^do- 

 men has a wide, white transverse marking, just l^ehind the middle, 

 and several angular marks behind it. On the front half are two 

 white spots. In the male the large middle marking is usually divided 

 into two white spots. 



The relative length of the legs is 4, 1, 2, 3 in the female, and 1, 

 4,' 2, 3 in the male. The dorsal eyes are very far forward, little 

 more than half as far from the front eyes as they are from each 

 other. 



The epigynum has a large oval opening divided in front into two. 

 The hinder edge over the transverse fold has a small projection in 

 the middle. Fig. 3c. 



The hook of the tibia of the male palpus is nearly straight and 

 has a short piece at the tip very narrow. Fig. 3^. The palpal 

 organ is oval, and the tube extends from the base around the inner 

 side, the end pointing outward. Fig. 3«,

Attus sylvestris, new sp. 



Male 4"^™ long. Cephalothorax abnost as wide as long. Abdomen 

 smaller than cephalothorax ; legs shorter and stouter than in A. pal- 

 ustris, and the male palpi nearly as large as in the male palustris, 

 which is half larger. The colors resemble those of Saitis pulex. 

 The legs are distinctly ringed with dark and light brown. The 

 cephalothorax is dark brown, covered with lighter hairs, which are 

 nearly rubbed off in the specimens. The male palpi have the tarsus 

 dark brown, and the rest of the palpus lighter above but dark 

 beneath. The tibia and patella are covered with white hairs that are 

 very long on the sides of the tibia. The palpal organ resembles 

 closely that of A. palustris, and is nearly as large. The markings
