middle line. At the sides of the middle band are pale stripes 

 indented on the outer side. On the under side the abdomen is 

 black, broken by a row of irregular spots on the sides. Fig. 11. 

 PL II. 



The palpus of the male is of middle size with the tarsus elongated 

 and furnished with a sharp curved process at the base, somewhat 

 as in B. furcatus, Em., Trans. Conn. Acad., 1913. On the outer 

 side is a smaller process near the base of the tarsal hook, as in 

 several species. The tarsal hook is short and recurved, with a 

 slender point turning at a right angle near the end. Kg. 11a. 



The epigynum projects outward from the surface of the abdomen 

 as in furcatus, but is not as large as in that species. 



Vancouver, Canada, 2 males, 1 female. 



Microneta pinnata. new sp. 



Male 2 mm. long, without any markings; legs and cephalo- 

 thorax pale yellow and abdomen gray. The head is high and 

 extends forward as far as the front of the mandibles. The male 

 palpi are large and complex. The tibia is widened on the under 

 side. The horn of the tarsus is straight and at a right angle to 

 the axis of the palpus. It has on the end a group of flat hairs cut 

 at the end into two or three teeth. Fig. 1. PI. III. The tarsal 

 hook is slender and curved backward, with two points at the base 

 and two at the end. The tube of the palpal organ is long and 

 slender, coiled one and a half times, and supported by a thin flat 

 appendage. 



Prince Albert, Canada. 



Microneta flava. new sp. 



2 mm. long, pale, and without markings; male and female of 

 the same size and general appearance. The male palpi are large 

 and but little darker in color than the rest of the body. The tarsal 

 hook is curved in several different directions, shown in the two 

 figures. At the base it is divided into two branches, the lower one 

 slightly turned outward, and along the basal edge is a ridge, also 

 turned outward. The end of the hook is turned at a right angle 

 to the base, pointed at the tip, and with a ridge on the outer side, 

 ending in a low tooth. Figs. 2a, 2b. PI. III. The epigynum is 

 of the usual kind, folded and projecting its diameter from the 

 surface of the abdomen. Fig. 2.
