Family STENOPELMATID.E. 



Although widely distributed over the surface of the earth, this 

 family of the Tettigonoidea is represented in South America and nearby 

 regions by only five genera, so far as at present known. Other 

 representatives of the family are found in Mexico and the United 

 States to the north. Not much is known concerning their food-habits, 

 but some of them at least are supposed to be predaceous or carni- 

 vorous. The various species undoubtedly are largely nocturnal in 

 their movements. Some burrow in the earth, while still others live 

 under stones, tree-trunks, boards, and different kinds of encum- 

 brances affording shelter, while some are dwellers in caves and under- 

 ground passages. 



The following synoptical key will aid in the recognition of the 

 genera which are known to occur in South American territory: 



Synopsis of the South American Genera of Stenopelmatid^. 

 A. Anterior tibiae provided with an auditory opening on both sides. 



b. Vertex viewed from above compressed. Fastigium of the vertex narrower 

 than the first antennal joint, sulcate. Occiput provided with a longi- 

 tudinal carina Schcenobates Saussure. 



bb. Vertex viewed from above plane or rounded. Fastigium of the vertex as 

 wide or wider than the first antennal joint, not sulcate. 

 c. Anterior tibiae above on the inner margin two or three-spined. 



d. Pronotum behind truncate, not covering the mesonotum. Front 

 tibiae above three-spined on the outer margin. 



Pherierus Brunner. 



dd. Pronotum produced behind, entirely hiding the mesonotum. 



Front tibiae above on the outer margin unarmed, with the 



exception of the apical spine Licodia Walker. 



cc. Anterior tibiae above on both margins, with the exception of the apical 



spines, unarmed Glaphyrosoma Brunner. 



AA. Anterior tibiae without auditory openings. Fastigium of the vertex between 

 the antennae defiexed, compressed, sulcate. Posterior tibiae robust, pro- 

 vided above with very strong spines Cratomehis Blanchard
