454. CLASS VIII. 
Trucalis Fasr. (Gryllus Acrida L.). Antenne depressed, ensi- 
form. Head conical, longer than thorax. Body elongate. Elytra 
narrow. Posterior feet very long, with tibia elongate, slender. 
Sp. Trucalis nasutus Fasr., Gryllus nasutus L., Rasev, Ins. 11. Locust. 
ind. Tab. Vv. (antenne badly drawn); DumérRIL, Cons. gén. s. 1. Ins. Pl. 24, 
fic. 3; Cuvimr, R. Ani. éd. illustr. Ins. Pl. 84, fig. 8, in south of Europe 
and in Africa ;—TZrux. variabilis, KuuG, and others, very similar species ; 
both the above-named species are also found at the Cape of Good Hope, 
the first also at Japan ; see DE HAAN, op. cit. pp. 141, 142. Comp. on 
this genus THUNBERG, Nov. Act. Soc. Upsaliens, 1x. 1827, pp. 76—88. 
Proscopia Kuuc. Body elongate, apterous. Head elongate, 
pyramidal, produced beyond the eyes; antenne subulate, very short, 
with six or seven joints. Prothorax very long. 
Sp. Proscopia radula Kuve, Cov. R. Ani. éd. ill. Ins. Pl. 85, fig. 1, from 
Brazil, like most of the species (all from America). These animals 
resemble Phasma in the habitus; and Mantis in the long prothorax. I can- 
not perceive a groove on the thighs for the reception of the tibie1. 
II. Posterior feet shorter than body. 
Pneumora Tuuns. Antenne filiform, with twenty-one to 
twenty-five joints. Head short, with eyes remote. Prothorax pro- 
duced into a membranous scutellum; thorax short. Abdomen in 
males inflated or vesicular. Greatest part of elytra incumbent 
horizontally on the back. Elytra and wings short in females; in 
some almost quite obsolete, covered by scutellum. 
Sp. Pnewmora variolosa, Latr., Gryllus variolosus, L., FaBr., Pnewmora 
marmorata, THUNB., Stout, Pl. 20, fig. 78; Cuvimr, R. Ani. éd.ill., Ins. 
Pl. 84, fig. 1; from the Cape of Good Hope. The other species also of 
this genus belong to the south of Africa. 
Phalanx II. Locustarie. Antenne setaceous, long (often 
longer than body), with joints numerous. Ocelli in most none. 
Tarsi with four joints. Females furnished with ovipositor bivalve, 
ensiform. In males the right, or more rarely both elytra, mostly 
furnished with a basal portion, orbicular, transparent (musical 
organ). 
1 CHARPENTIER records a winged species from Chili. Elytra were not present; 
wings very small ; but what seems most to distinguish this species is the absence of a 
pulvillus or plantula on the tarsus. Hence it might form a distinct genus Astroma
