Cephalothorax, i-2"'"" k>ng and dark brown. The head is wide and 

 round, and the eyes small. The mandibles are long and without a 

 large tooth in front. The legs are stout and brownish yellow. The 

 palpi are short, a little longer than the femur of the tirst legs. The 

 tibia of the male palpus is short except on the upper side, where it 

 extends over the tarsus. The tarsal hook is large and wide 

 at the base, curving outward at the tip, which is slightly widened. 

 The tarsus and palpal organ are dark brown and about as 

 wide as long. The tube appears to be partly hidden under the edge 

 of the tarsus and supported at the end by various short processes.

Erigone (Menge.) 

 In this genus I include only those spiders of wliich the males have 

 long palpi with a tooth under the end of the patella. The maxillaa 

 and the mandibles are much thickened at the base. The tarsus and 

 palpal organ are small. The females diifer but little from those of 

 the related genera.

This is smaller than the other species, being little over a millimeter 

 long. The colors are lighter than usual. The abdomen is yellowish 

 gray, the legs orange-yellow, and the cephalothorax bright orange, 

 especially on the head and mandibles. The eyes are surrounded 

 with black. The bright color of the head makes this spider easy to 

 recognize among the species which fly in autumn. The males and 

 females are of the same size and color, though the latter are slightly 

 paler. The mandibles of the male are large* and have two rows of 

 strong teeth inside the tip. The palpi have a long and pointed spur 

 on the patella. Fig. 8J. The tibia is short but expanded as iisual 

 at the end. The palpal organ is much like the other species. 



This species is common on fences in October and November, in
