their ready separation. Hence none will be attemjited at this time. 

 These small crickets very likely agree fairly well with the members of 

 GryUodes and Gryllus in their haunts and habits. 



The following listed species appear to be represented among the 

 material at hand. 



41. Miogryllus pusillus (Burmeister). 



Gryllus pusillus Burmeister, Handb. Ent., II (1838), p. 733; Saussure, Mem. 



Soc. Geneve, XXV (1877). P- i94; PI- 12 (XI), figs. 7, 7e, f. 

 GryUodes pusillus Saussure, Miss. Mex., Orth. (1874), p. 416, PI. 7, fig. 6. 

 Miogryllus pusillus Saussure, Biol. Cent.-Amer., Orth., I (1897), p. 227; Kirby, 



Syn. Cat. Orth. II (1906), p. 38. 



Habitat. — There are two males and one female in the collection 

 made by H. H. Smith at Santarem, Brazil. I also find another male 

 bearing the label "Chapada, Brazil, Ace. No. 2966." This last insect 

 was taken in October. The species is also recorded from Mexico, 

 Guiana. Peru, etc., showing a rather wide distribution. 



42. Miogryllus micromegas (Saussure). 



GryUodes micromegas Saussure, Miss. Max., Ortli. (1874), p. 418. 

 Gryllus microynegai Saussure, Mem. Soc. Geneve, XXV (1877), p. 196. 

 Miogryllus micromegas Saussure, Biol. Cent.-Amer., I (1897), p. 227; Kirby, Syn. 

 Cat. Orth., II (1906), p. 39. 



Habitat. — Two females of still another species of this genus are 

 referred here. One of them comes from "Bom Jesus de Lapa, Rio 

 Sao Francisco, Brazil," where it was taken Dec. 8, 1907, by Haseman. 

 The other is labeled " Prov. del Sara, Bolivia, 350 M. J. Steinbach, 

 II, 1913." 



43. Miogryllus brevipennis (Saussure). 



GryUodes brevipennis Saussure, Miss. Mex., Orth. (1874), P- 4i8. 

 Gryllus brevipennis Saussure, Mem. Soc. Geneve, XXV (1877), p. 195. 

 Miogryllus brevipennis Saussure, Biol. Cent.-Amer., Orth. I (1897), p. 227; Kirby, 

 Syn. Cat. Orth., II (1906), p. 39. 



Habitat. — I find a pair of these little crickets which I place with 

 Saussure's M. brevipennis. They come from Santa Cruz de la Sierra, 

 Bolivia, at an altitude of 450 meters above sea-level, and were taken 

 by J. Steinbach. They belong to Accession No. 4546. 



These little crickets resemble representatives of the genus GryUodes, 

 but have both sides of the anterior tibia perforated, a character 

 belonging to Miogryllus.
