Supplement to the New England Spiders. 193 



thorax Light yellow tinged, when fresh, with light red on the head 

 and mandibles. There is a row of four or live hairs directed forward 

 on the middle line of the head. The abdomen is covered above 

 and below with scattered hairs about their length apart. The 

 mandibles of the male have a strong tooth in front. The sternum 

 extends backward between the fourth coxae and is truncated at the 

 hinder end, where it is about half as wide as the fourth coxa. The 

 epigynum appears very simple externally, showing two small sper- 

 mathecae through the skin, over which the short scattered hairs are 

 arranged in two clusters. The male palpi have been sufficiently 

 figured in N. E. Therididae. 



Tineticus flaveolus, Banks. Proc. Acad. Nat. Sci. Phila., 1892. 

 (Plate IV, figures 8, 8 a, 8b.) 



This species resembles T. longisetosus in size and color. It is 

 1.5 mm, long. When fresli the cephalothorax is light orange color 

 and the rest of the bod}' pale. The sternum extends backward 

 beyond the fourth coxae, where it is as wide as one of the coxae. 

 The mandibles of the male have a small spine on the front near 

 the end. The epigynum is much like that of longisetosus, with a 

 transverse slit with the spermathecae showing through the skin. The 

 male palpus resembles that of longisetosus, but the tibia and tarsus 

 are both slightly shorter. The tibia is widened at the end as it is 

 in longitarsus, with several projections and shallow curves on the 

 edge. The tarsus has two large spines near the base, one much 

 thicker than the other and both about half as long as the corres- 

 ponding spines in longisetosus.

 (Plate IV, figures 3, 3 a, 3b.) 

 2 mm. long, and pale yellow, brown and gray, with some individ- 

 uals almost white. The group of eyes is rather narrow, not more 

 than half the width of the thorax. The sternum is widest at the 

 second legs, and extends between the fourth coxae in a narrow 

 piece not more than half the diameter of one of the coxae. The 

 male palpi are large and the palpal organs of a very distinct form. 

 The tibia is small, but widened at the end, where it is about twice 

 as wide as at the base. The tarsus is long and oval, with a smooth 

 strip without hairs near the outer edge. The tarsal hook is slender 

 and has a short rounded process near the base on the outer side.
