ovipositor, the latter extending somewhat beyond the apex of the hind 

 legs when fully straightened out. Wings only a little shorter. 



Form moderately robust, somewhat resembling a small Grylliis in 

 general appearance, but lacking the perforation on the inner side of 

 the anterior tibiae, and having the areoles of the dorsal portion of the 

 tegmina in the female quadrate, instead of rhomboidal, as in Acheta 

 and Gryllus. Head shining black, moderately large, subrotund, of 

 about the same width as the anterior edge of the pronotum. Front 

 about twice the shorter diameter of one of the eyes, the latter not 

 prominent, a little elongate up and down; the ocelli arranged in an 

 arcuate line, the lateral ones rather large and prominent. Front 

 provided with an inverted broadly Y-shaped testaceous marking, 

 the upper extremity of the shank of which reaches a point on a level 

 with the center of the base of the antennae. Occiput provided with 

 six prominent testaceous lines. Genae and mouth-parts pallid, the 

 palpi dirty white, or pale testaceous. Pronotum somewhat pubescent, 

 nearly twice as broad as long, the sides gently rounded, the anterior 

 margin widely and evenly emarginate, the hind margin somewhat 

 sinuose; the disk dark brown and rather prominently varied with 

 testaceous, the lateral lobes having the superior portion piceous, the 

 inferior portion pallid. Tegmina complete, almost reaching the apex 

 of the abdomen, the humeral angle and the costal area pallid, the 

 remainder fuscobrunneous. Legs testaceous, the hind femora em- 

 browned. Wings pallid, lengthily caudate, extending fully three- 

 fifths of their length beyond the tip of the tegmina. Ovipositor 

 slender, filiform, excessively long. 



Length of body, 9 , 12 mm.; length of pronotum, 2.5 mm., width, 

 4.5 mm.; length of tegmina, 8 mm., of wings, 20.5 mm., of hind 

 femora, 10 mm., of ovipositor, 15 mm. 



Habitat. — The type, a female, and the only specimen at hand, comes 

 from Bahia, Brazil, west of Jacobina on road to Catinga, Nov. 10,
