Genus Lebinthus Stal. 



Lebinlhus Stal, CEfv. Vet.-Akad. Forh., XXXIV, pt. i (1877), p. 50; Bolivar, 

 An. Soc. Espan., XVIII (1889), p. 425; Kirby, Syn. Cat. Orth. II (1906), p. 88. 

 Paraeneopteriis Saussure, Mem. Soc. Geneve, XXV (1878), p. 533. 



This is an oriental genus, the representatives of which, at least for 

 the most part, are confined to the Philippines and adjacent regions. 

 Under the generic name PorcEneopterus of Saussure. however, Giglio- 

 Tos has credited a species to Darien. Stal and Saussure both selected 

 the same species for the type of their respective genera. 



90. Lebinthus elegans (Giglio-Tos)? 



Paraeneopteriis elegans GiGLio-Tos, Boll. Mus. Torino, XII (1897), No. 301, p. 8. 

 Lebinthus (?) elegans Kirby, Syn. Cat. Orth. II (1906), p. 88. 



Habitat. — There is a single nymph at hand of what seems to be an 

 example of this genus. As compared with typical specimens of L. 

 bitmniatus from the Philippines, the nymph referred to here seems to 

 be congeneric. The broad dorsal pale stripe as described for elegans 

 will apply to our nymph. It is therefore referred to Giglio-Tos's 

 species, but with some doubt. Our specimen seems to come from 

 Para (Brazil) where it was taken during the month of July presumably 

 by H. H. Smith. It is deposited in the Carnegie Museum. 



Other specimens of apparently the same insect are in the writer's 

 collection. The}' were collected at Pernambuco, Brazil. Possibly 

 they may be the immature stages of Ligypterus heydeni Saussure, 

 which also occurs in Brazil. 



Family STENOGRYLLID^. 



This family of Grylloidea is composed of rather large and moder- 

 ately robust insects, in which the hind tibiae are biseriately spincd, 

 instead of having these members both spined and serrate. In habits 

 these crickets are subarboreal. living on, or near, the ground among 

 fallen leaves and herbage. Their colors are chiefly testaceous, ochra- 

 ceous, or fulvous with some darker markings. At least two genera 

 are known from tropical America.

the lateral lobes a little narrowed in front Stenogryllus Saussure, 



A A. Anterior tibia without an auditory opening. Lateral lobes of the pronotum
