In studying series of South American Gryllidae, we find 

 that the majority of forms of diminutive size and abbreviate 

 tegmina described as members of the genus Nemobius belong 

 instead to the present genus. 1 Those of which we have mate-

 bius basalis of F. Walker 2 is described as having 3 spines on 

 the dorsal margins of the caudal tibiae and, in consequence, 

 almost certainly belongs to the present genus. Hygronemobius 

 has 3 and 3 spines on the dorsal margins of the caudal tibiae, 

 the distal spurs numbering 3 external and 2 internal ; Nemo- 

 bius has 4 and 4 spines and 3 pairs of distal spurs. These
