154 INSECTA. 
MyrMEcopHita.—Spuxrium, Charp. 
The Myrmecophile have no wings; and the body is oval. With 
respect to their antenne, and the absence of simple eyes, they resem- 
ble the true Grylli.. The posterior thighs are extremely large. 
The only species known—Blatta acervorum, Panz. Faun. 
Insect. Germ., LX VIIT, 24—lives in ant-hills *. 
Sometimes the elytra and wings are tectiform, and the tarsi are 
quadriarticulated. The antenne are always very long and setaceous. 
The mandibles are less dentated. and the galea is wider than in the 
Grylli. The females always have a projecting ovipositor, com- 
pressed, and in the form of a sabre. 
They have but two ceca, like the preceding Insects, but the biliary 
vessels surround the middle of the intestine, and are inserted directly 
into it. 
These Orthoptera are herbivorous, and form the genus 
Locusta, Geoff., £ab.—Gry.ius TETTIGONIA, Lin. 
Such, for instance, are the 
L. viridissima, Fab.; Rees., Insect., II, Gryll., x, xi. Two 
inches long; green and immaculate; ovipositor of the female 
straight. 
L. verrucivora, Fab.; Rees., Ib., viii. An inch and a half long; 
brown; elytra spotted with brown or blackish; ovipositor of the 
female recurved. It bites with considerable severity, and it is 
said that the Swedish peasants are in the habit of making it bite 
the warts on their hands, and that in consequence of those ex- 
crescences recciving into the wound the black and bilious fluid 
poured into it by the Insect, they become desiccated and disap- 
pear. 
Several species of this genus are apterous, or have but very 
short elytra. Such is the 
L, ephippiger, Fab., Ross., Faun. Etrusc., II, viii, 3, 4 f. 
* It is the subject, if I mistake not, of a Memoir from the pen of M. Paul 
Savi. 
+ This species, and some others, in which both sexes are almost apterous, or pre- 
sent at most but very short elytra resembling rounded and arched scales, form the 
genus EpHIpPIGER of my Fam. Nat. du Régn. Anim. That of ANISOPTERA is 
composed of species, the males of which are winged, and the females apterous or 
merely furnished with very short elytra; such are the L. dorsalis, brachyptera., of M. 
Toussaint Charpentier. The species provided with ordinary elytra and wings, in 
which the antenne are simple, and the front is not elevated pyramidically, form the 
genus GRYLLUS proper. Such are the first two species above described. Add to 
them the Locusta varia, Fab. ; Panz., Ib., XX XIII, 1 ;—L. fusca Ib., ii;—L. cly- 
peata, 1b., iv ;—L. denticulata, Ib., y. His Gryllus proboscideus, Ib., XXII, 18, is 
the Panorpa hiemalis.

Those Grylli, in which the front is elevated in the manner of a pyramid or cone, 
have been generically distinguished by Thunberg, under the name of CoNocEPHA-
