88 Illinois State Lahorafory of Natural Historij. 



Described from many specimens collected at Cobden, Union 

 Co., 111., 25th September, 1886. We have also specimens from 

 Johnson county. 



The males of this species are much more numerous than 

 the females. Out of a large number of specimens collected, I 

 was surprised not to find a single female. Wood states that he 

 found six times as many males as females. According to him, 

 "The females are to be distinguished by their larger size, the 

 brown color of their legs and palpi, as well as the darker and 

 less uniform color of the dorsum, which also frequently loses 

 almost all of the reddish tint." 



This species is chiefly remarkable for the enormous length 

 of its legs. Though the body is very small, the legs are im- 

 mensely developed. Like L. vittatum, this harvest-man fre- 

 quents the rocky ledges of southern Illinois, where it is quite 

 abundant. I have never taken it anywhere else.

Dorsum minutely tuberculate (almost appearing finely 

 granulate), of a rich dark golden-brown color, somewhat 

 darker in front, with a faint indication of a dark central mark- 

 ing in some specimens. Eye eminence well pronounced, longer
