Superfamily Argiopoidea 



Lycosa pictilis (L. pic'ti-lis). — The cephalothorax is chocolate- 

 brown, with a median grayish band, which begins at the second 

 row of eyes, extends between the eyes of the third row, and then 

 abruptly bulges on each side, being much wider than the eye-space 

 midway between the eyes and the median furrow, then narrowing 

 to the median furrow, where it is about the same width as the eye- 

 space. The abdomen is dark brown above, with a black spot on 

 each side at the base, which in the female encloses a light spot 

 but not in the male; on each side, between the basal black spot 

 and the middle line of the body, there is a large light spot; on 

 the hinder part of the abdomen, there is a series of chevrons; at 

 the outer end of each of the chevrons is a light spot enclosed by 

 black, and in front of each half of each chevron is a light-coloured 

 spot. The form of the epigynum is shown in Fig. 720, /. The 

 male measures nearly two fifths inch in length; the female, about 

 one half inch. 



Mr. Emerton, who first described the species, states that 

 it is abundant among the moss and low shrubs on the upper part 

 of Mount Washington, N. H., and the neighbouring mountains. 



Lycosa rubicunda (L. ru-bi-cun'da). — The cephalothorax is 

 dark reddish brown above with a light brown median band; the 

 hairs with which it is clothed are very short and sparse, which re- 

 sults in the carapace having a polished appearance; the median 

 light band is wider than the eye-space in front, behind the eye- 

 space it narrows rapidly to the median furrow. The abdomen is 

 gray, light in the middle, and with many closely placed dark dots 

 and dashes on the sides. The length of the body is about two 

 fifths inch. 



Emerton, who redescribed this species under the name Lycosa 

 polita, states that it is found under stones in summer and under 

 leaves in winter. Its known range extends from New England 

 west to Indiana and south to District of Columbia. 



Lycosa avara (L. a-va'ra). — The cephalothorax is marked 

 with a light median band, which begins at the second row of eyes 

 and extends to the hind end of the carapace; it is widest between 

 the third row of eyes and the median furrow where it is as wide as 

 the third row of eyes; it is somewhat abruptly contracted at the 

 anterior end of the median furrow, and then gradually narrows 

 to the posterior end of the carapace. The abdomen is clothed 

 with gray and brown hairs, and bears an indistinct lanceolate
