Bathyphantes tristis. 



The median rounded part of the epigynum shows two cavities on 

 the posterior edge. Probably the female of some described Micro- 

 neta or Bathyphantes (PI. XI, fig. 17). 



Microneta latens = !/• quinquedentata Emer. 

 Microneta palustris. 



This is a Pedanostethus; I give a figure of the other side of palpus 

 (PI. XI. fig. 16) ; this docs not seem to agree with any described species; 

 the epigynum of the females (PL XI, fig. '25) (collected after descrip- 

 tion was made) agrees very well with one of Emerton's figures of 

 riparius. 



Microneta luteola. 



I give a figure of other side of palpus (PI. X, fig. 2), it were prob- 

 ably better in Bathyphantes, and related to B.calcaratus Emer.; there 

 are, however, no marks on the basal part of the abdomen, but several 

 taint, whitish, transverse spots toward tip. 



Microneta flaveola. 



This is probably only a form of Bathyphantes angulata; the hook, 

 however, is not as heavy as in that species, and there are several 

 structures not shown on Emerton's figure. In the original figure 

 a part of the median bilobed process was mistaken for a continuation 

 of the upper limb of the hook (PL X, fig. 9). 



Microneta complicata. 



A figure is given of the back of the palpus (PL X, fig. 14); it is 

 related probably to Bathyphantes intricata Emer., but distinct. 



Microneta minutissima. 



The size given was a little too small; it is about 1.1 mm. long (PL 

 X, fig. 12). 



Microneta frontata. 



This is a Pedanostethus, and it agrees well in size, color, and epigy- 

 num with what Emerton figures as his female P. pumilus, and I 

 believe it is the same. 



Microneta gigantea. 



This appears to be Tmeticus brunneus Emer., the female of which 

 was figured in 1909. The low, broad head and small A. M. E. would 

 seem to indicate a special genu-. 



Microneta distincta. 



Perhaps better placed in Tmeticus. I give new figures (PL X, 



fig. 1) of the palpus; apparently not otherwise known.
