INSECTA. 463 
which BurMeIsTER changed into Dematoptera, had been previously 
(see above, p. 449) given by Dz Grzr to the order of the Orthoptera. 
Léon Durour, who subsequently proposed the same separation, 
named these insects, in imitation of Dum&rit, Labidura; West- 
woop Luplexoptera (Zool. Journal, 1831, Modern Classification, 1. 
1839, p. 308). At all events these insects have greater agreement 
with the Orthoptera than with the Coleoptera ; they differ from the 
last by their incomplete metamorphosis and by many particularities 
of internal structure. The great size of the under-wings in com- 
parison with the elytra is very common in the Orthoptera (to refer 
to Phasma alone), and the reflexion of the point of the wing also is 
not wanting in some other Orthoptera, as, ex. gr. Anaplecta, the last 
of the sub-genera of Llatta recorded above. 
Forficula L. Body depressed, narrow, elongate, with prothorax 
quadrate. Antenne filiform, a little longer than half the body, with 
joints very distinct, mostly more than twelve (ten to forty). Ocelli 
none. lLabrum entire, orbicular; mandibles denticulate; labium 
bifid, with palps short. Abdomen with last segment forcipate, with 
forceps horny, moveable, in males arcuate, or more open.

Earwigs, perce-oreilles, Ohr-wiirmer. It is said that they creep into the 
ears, and hence this name; this they do not more than other insects, which 
by chance may get into the ears of persons asleep. They live in moist 
places, and eat almost everything; they are especially fond of fruits and 
honey. The females sit on their eggs, and guard them; the young also 
creep under their mother, like chickens under the hen, and she often sits 
quietly for hours together over them. DE Grrr, Mém. s. 1. Ins. 11.

Note.—Some are without hind-wings but provided with elytra, or are 
entirely apterous. According to difference of form and number of joints 
in antenne, LEACH, LATREILLE, and especially SERVILLE, have formed 
several sub-genera, of which it may here suffice to cite the names; Apachya, 
Mecomera, Sparatta, Diplatys, Forficula, Echinosoma, Lobophora, Pyragra,
