Genus Phyllogryllus Saussure. 



Phyllogryllus Saussure, Mem. Soc. Geneve, XXV (1878), p. 558; Biol. Cent.- 

 Amer. Orth., I (1897), p. 257; Kirby, Syn. Cat. Orth., II (1906), p. 92. 



The present genus seems to be confined to tropical South America 

 and presumably contains several species. But two are recognized in 

 Kirby's Synonymic Catalog of the Orthoptera since he unites a couple 

 of the described forms.

Habitat. — Four females and three males together with five nymphs 

 of an insect which in a measure agree with Walker's characterization 

 of velutinus are referred to this species. These insects were taken at 

 Chapada, Brazil, during the months of August and September (H. H. 

 Smith). In addition to these I find two males labeled "Rio Guapore, 

 below the Rio Sao Miguel, Brazil, Aug. 22, 1909 (Haseman)." These 

 latter bear a general resemblance to the Chapada specimens, but differ 

 materially in several respects both as to structure and coloration. 



It is barely possible, therefore, that we have at least two species 

 here. The P. mortuifolia Saussure from Cayenne is larger than our 

 specimens, while the P. pipilans Saussure is undoubtedly distinct 

 from the others, thus suggesting at least four species. At present, 

 however, I shall not attempt to separate these forms any further, 

 leaving this for the future, when more material shall have been 

 accumulated.
