198 J. H. Emerton, 
general color is gray, paler on the legs, and there is great differ- 
ence in the depth of color in different individuals. In alcohol the 
wetting of the hairs makes them paler and more translucent, and 
they soon become yellow. The abdomen is marked with four 
longitudinal lighter lines partly broken into spots. There are no 
markings on the cephalothorax, except a little black around the eyes. 
The epigynum is not folded, but extends backward half way to 
the spinnerets, curved slightly inward toward the body and out- 
ward again at the tip, Pl. IV, fig. 12d. 
The male palpi have the tibial hook large and wide, turning 
outward with three teeth on the thickened edge. The base of the 
tarsus has a shght horn, shorter than in waria. The end of the 
palpal organ has two small black processes, one twice as long as 
the other, Pl. IV, fig. 12a, which show from below when the palpi 
are held in the usual position. 
Microneta serrata. (Plate IV, figures 15, 15a, 15h.) 
One male from a fence in Boston, Nov. 20, 1900, during the 
autumn flight. Length 1.6mm. The cephalothorax is a third longer 
than wide, and narrowed toward the front. The eyes cover the 
whole front of the head and are Jarge for the size of the spider. The 
front middle eyes are only slightly smaller and closer than the 
upper middle pair. The cephalothorax is highest in the middle 
where it is more than half as high as wide. The sternum is large 
and convex, widest in front, and ending in a blunt point between 
the fourth coxe. 
The male palpi are very peculiar. The patella is as long as wide; 
the tibia is twice as long as the patella and a little widened at the 
end, with a thin projection on the outer upper corner, extending 
forward and turned a little inward. There is a little ridge on the 
back of the tarsus parallel to this process. The tarsus has a slight 
spur at the base. The tarsal hook is slender as in several small 
Bathyphantes. The middle appendage of the palpal organ is larger 
than in Microneta viaria and has on the outer side a line of short 
black spines, Pl. IV, fig. 15a.

Comparison of several specimens from western Canada leads me 
to think that s:/vatica, solitaria and mgra are all varieties of angu-
