Bruner: South American Crickets. 415 



Genus Stenogryllus Saussure. 

 Stenogryllus Saussure, Mem. Soc. Geneve, XXV (1878), p. 554. 



Only a single species of this genus is known. It is the Stenogryllus 

 phthisicus Saussure from St. Domingo, West Indies. No specimens 

 of it are at hand. 



Genus Pseudogryllus Chopard. 



Pseudngryllus Chopard, Ann. Soc. Ent. France, LXXXI (1912), p. 411. 



Like the preceding, the present genus is monotypic, containing so 

 far as at present known only the species P. elongatus Chopard from 

 French Guiana, unless we can include the insect described as Metrypiis 

 heros Brunner and its allies, which are mentioned below under the 

 generic name Tafalisca Walker.

 Melrypus Saussure, Mem. Soc. Geneve, XXV (1878), p. 671. 



The present genus is composed of about a dozen species of moder- 

 ately large and fairly robust crickets, most of which are to be found 

 in the West Indies and the northern countries of South America. 



91. Tafalisca lineatipes sp. nov. 



Most closely related to the Metrypus luridus of Saussure, as de- 

 scribed in Mem. Soc. Geneve, XXV, p. 673, pi. 19 (LXXIII), figs. 

 3h, 3b, but apparently not the same as Tafalisca lurida Walker. 



Large, robust, testaceous, the head, legs, and abdomen covered 

 with a close, short, pale, silky pile. The pronotum bordered narrowly 

 in front and broadly behind by dark piceous. Hind femora provided 

 externally with a prominent longitudinal black line, the hind tibiae 

 brunneo-ferruginous, and the ovipositor piceous. 



Length of body, 9 , 36 mm., of pronotum, 5.5 mm., width, 6 mm., 

 length of tegmina, 27 mm., of wings, 30 mm., of hind femora, 17 mm., 

 of ovipositor, 16 mm. 



The dorsal field of the tegmina of this insect is provided with 

 longitudinal veins, and between them is weakly but rather closely and 

 irregularly' reticulate; at the sides the reticulation is mixed, this area
