Genus Cylindrogryllus Saussure.

 Cat. Orth., II (1906), p. 92. 

 This genus, which is known by a single species, seems to be confined 

 to Brazil. Just what its habits are seems to be doubtful, otherwise 

 it is possible that more material would be available for study.

Habitat. — The collections made by H. H. Smith in April at Chapada, 

 Brazil, contain two female specimens of a small gryllid, which run to 

 the genus Cylindrogryllus of Saussure. Since but a single species of 

 the genus is known, and these specimens agree fairly well with the 

 characterization of C. brevipennis, as given by Saussure, they are 

 referred to it. As long as the male alone was described, the subjoined 

 brief description of the female is now added. 



Rather small, cylindrical, slender, entirely destitute of tegmina and 

 wings, entire body together with the legs rather closely pubescent, 

 pale brunneo-ferruginous, the legs and underside a little paler. Head 

 large, wider than the anterior margin of the pronotum, the eyes promi- 

 nent, but not exceptionally large, fully twice as far apart as their 

 diameter; the front rather broadly rostrate and roundly protuberant; 

 ocelli inconspicuous, the anterior one situated in a depression, located 

 on a line drawn from the superior edges of the antennal scrobes. 

 Pronotum cylindrical, nearly twice as long as broad, the anterior and 

 posterior edges provided with a rather heavy border, very gently 

 but roundly emarginate at its middle. Abdomen long and slender, 

 gently fur-iform; ovipositor moderately robust, gently arcuate, the 

 apex spear-shaped with the lateral edges faintly crenulate. Hind 

 femora moderately robust; metatarsus provided at its sides above 

 with 2 : 3 short coarse spines or teeth.

 it would fall in the section AA. — The author.
