being provided with both quadrate and irregular areoles. The anterior 

 femora are rather broadly inflated and evenh' arcuate above. The

Habitat. — The type and only specimen at hand comes from Jamaica, 

 W. I., and bears the Carnegie Museum Accession No. 2306. 



Judging from the structure of the apex of the ovipositor of this 

 insect and its allies I would suggest a relationship to the genus Pseudo- 

 gryllus Chopard (Ann. Soc. Ent. France, LXXXI, p. 411) which genus, 

 along with Stenogryllns are suggested as forming a separate group. 



Family PODOSCIRTID^. 



This is one of the most extensive families of the Grylloidea and is
