1. Persistent (Persistentes). Legs which the insect has in all its states.—Ex. The legs attached to the trunk. N.B. These are called Legs (Pedes). Plate [XVIII]. Fig. 11. a.

2. Deciduous (Decidui). Legs which the insect has not in all its states.—Ex. Membranous legs of Caterpillars. Plate [XVIII]. Fig. 11. b. N.B. These are called Prolegs (Propedes).

3. Acquired (Acquisiti). Legs which the insect has not in its first state, but which it acquires subsequently.—Ex. Abdominal legs in Scolopendra, Iulus, &c.

D. Denomination.

1. Fore-Legs (Antici). The first pair. Taken by themselves called Arms (Brachia).

2. Anterior (Anteriores). The two first pair of legs.

3. Mid-legs (Intermedii). The middle pair of legs.

4. Hind-legs (Postici). The last pair of legs.

5. Posterior (Posteriores). The two last pair of legs.

6. Abbreviate (Abbreviati). Legs with an imperfect tarsus.—Ex. Vanessa.

7. Ambulatory (Ambulatorii). When the tarsi have a spongy sole.—Ex. Chrysomela.

8. Cursorious (Cursorii). When, the fore tarsi of some males excepted, they have not a spongy sole.—Ex. Carabus, Cicindela. Plate [XIV]. Fig. 7.

9. Saltatorious (Saltatorii). When the hind-legs have strong incrassated thighs formed for leaping.—Ex. Haltica, Orchestes, the Locustina. Plate [XIV]. Fig. 5.

10. Natatorious (Natatorii). When the legs are compressed or ciliated, and formed for swimming.—Ex. Dytiscus, Gyrinus, Notonecta. Plate [XIV]. Fig. 6.

11. Motatorious (Motatorii). Legs, which when the insect is at rest, are in a perpetual vibratory motion.—Ex. Tipula.

12. Fossorious (Fossorii). Leg with either palmate or digitate tibiæ.—Ex. Scarites, Clivinia, Gryllotalpa. Plate [XV]. Fig. 5, 6.

13. Raptorious (Raptorii). When the strong porrected thighs, usually of the fore-leg, have a channel for the reception of the tibiæ, which are inflexed, and both armed with a double series of spurs.—Ex. Mantis, Nepa.

14. Prehensorious (Prehensorii). When the thighs of the hind-legs converge and the tibiæ diverge so as to form an angle which is armed with spines.—Ex. Gonyleptes. Plate [XIV]. Fig 8[1115].

E. Hip (Coxa).

1. Fixed (Fixæ). When they are not moveable.—Ex. Dytiscus, Gonyleptes.

2. Free (Liberæ). When they are moveable.—Ex. Hymenoptera, most Coleoptera.

3. Laminate (Laminatæ). When the posterior coxæ form a broad thin plate which covers the trochanter and the base of the thighs.—Ex. Haliplus. Plate [XV]. Fig. 1. p´´.

4. Flocculate (Flocculatæ). When the posterior coxæ are distinguished by a curling lock of hair (Flocculus).—Ex. Andrena[1116].

F. Trochanter (Trochanter).

1. Fulcrant (Fulcrans). When the trochanter merely props the thigh below at the base, but does not at all intervene between it and the coxa.—Ex. Carabus.

2. Intercepting (Intercipiens). When the trochanter intervenes between the thigh and the coxa, so as intirely to separate them.—Ex. The Petalocerous beetles, Hymenoptera, &c.

3. Monomerous (Monomerus). When it consists of only one joint.—Ex. Coleoptera, &c.

4. Dimerous (Dimerus). When it consists of two joints.—Ex. Ichneumon.

G. Thigh (Femur).

1. Simple (Simplex). When it is no where particularly thick.

2. Incrassate (Incrassatum). When it is very thick, either partially or generally, and formed for leaping.—Ex. Haltica, &c.

3. Loricate (Loricatum). When the disk of the thigh appears covered with a double series of oblique scales like a coat of mail.—Ex. Locusta. Plate [XIV]. Fig. 5.

H. Shank (Tibia).
