apex on both margins without teeth. General color as in dissimilis,

Length of body, cf , 4.5 mm., 9 , 5.2 mm. 



Habitat. — The types, a male and a female, are labelled " Piedra 

 Blanca" and "April," as are three other specimens, a male and two 

 nymphs. There is, however, an additional very imperfect male

 collected by H. H. Smith. These insects are the property of the 

 Carnegie Museum.

4. 4A. 4B. 

 Habitat. — There are two females of this species among the material 

 collected by H. H. Smith at Santarem, Brazil. They agree well with 

 Saussure's characterization of the species. 



Genus Hemigryllus Saussure. 



Hemigryllus Saussure, Mem. Soc. Geneve, XXV (1877), p. 100; Kirby, Syn. Cat. 

 Orth., II (1906), p. 20. 



This genus seems to be monotypic and is confined to South America, 

 where it is not at all rare, if we are to judge from the material at hand. 

 It also has a fairly extended distribution. 



36. Hemigryllus kriechbaumeri Saussure. 



Hemigryllus kriechbaumeri Saussure, Mem. Soc. Geneve, XXV (1877), p. loi,
