Type, 2, in coll. E. Simon. Total length 18 millim. 
Hab. Mexico, Ciudad in Durango (Forrer+), Omilteme in Guerrero (H. H. Snuth). 
Subfam. LIOCRANINA. 
The genera included in this subfamily may be distinguished from those of the 
Clubionine and Micariinee by the presence beneath the tibie and protarsi of the first 
and second pairs of legs of a double series of more or less numerous long spines. The 
two genera Chemmis and Heterochemmis may be separated from Liocranum by the fact 
that the tarsi of all four pairs of legs are furnished with claw-tufts. They may be 
known from each other by the difference in size of the anterior central eyes and in the 
number and disposition of the spines on the tibize and protarsi of the legs. 
The three genera represented in Central America may be tabulated thus :— 
a. Posterior pair of spinners with a long terminal segment. . . . Sysprra, Simon. 
6. Posterior pair of spinners with a very short terminal segment. 
1. Eyes of anterior rowequal . . ..... . . . . HETEROCHEMMIS, gen. nov. 
2. Central eyes of anterior row much larger than the laterals . . Cx#emmnis, Simon.
