INSECTA. 457 



black body, without the elongated point at the wings, which in the 

 preceding species extends behind the elytra. 



Note. Eneoptera BURM. (Platydactylus BRULLE and SERVILLE in part). 

 The generic name devised by BURMEISTER on account of the elytra similar 

 in both sexes of some species, having no musical organ in males ; comp. 

 BURMEISTER, Handb. derEntomol. 11. 2, p. 1015, and on the typical species, 

 DE HAAN, 1. 1. p. 231. The name of Platydactylus ought to be rejected, 

 since given long previously to a genus of Saurians. In these Achetce the body 

 is elongate , posterior feet very long ; ovipositor of females long, recurved 

 upwards, with valves divergent, clavate at apex. Sp. Acheta brasiliensis 

 FABR., Gryllus surinamensis DE GEER, Mem. in. PI. 43, fig. i, GUERIN, 

 Iconogr., Ins. PL 54, fig. i, (named Gryllus Servillei). 



b) Pronotum oblong, narrower forwards. 



Phalangopsis SERVILLE. Feet elongate. Elytra short ; wings 

 none, or very short rudiments of wings.

 Habit, in South America.

 Ins. Heft 22, Tab. 17. 



Note. BRULLE and SERVILLE assign four joints of tarsi in posterior 

 feet to these insects, which BURMEISTER has shewn to be an error, Handb. 

 der Entomol. n. 2, p. 731. 



Gryllotalpa LATE, (species of Acheta FABR.). Anterior feet 

 bssorial, compressed, broad. Antennas setaceous, shorter than 

 >ody. Ocelli two, placed between the compound eyes. Pronotum 

 ilongate, oval, gibbous ; ovipositor of female none.

 xiv. xv. ; DUMERIL, Cons. gen. s. 1. Ins. PL 25, fig. 7 j the mole-cricket, 

 i ^ " long, brownish-black, yellow below, with grey-brown, darker- veined 

 shield-covers. The fore-feet work like saws, or as spades, with which these 

 insects burrow the ground. The female lays her eggs in a hole under 

 ground, to which a long curved passage leads, in and out of which she 

 often creeps ; at first the young ones live close together, but soon disperse. 

 Horse-dung appears to attract these animals, swine-dung to repel them. 

 They live especially in garden-mould and turfy bog. On the anatomy see

 Europe and of Asia, and other species of this genus are found in all parts 

 of the world. 



Gylindrodes GRAY, SERVILLE. Body elongate. Vestiges alone of
