The others are membranous, fleshy, generally conical or cylin- 
drical, contractile, and taking, according to the will of the animal, 
very different forms. Fig. 95 represents, after the same memoir 
of Réaumur’s, the different forms of the membranous legs of

the Silkworm caterpillar. This plate gives a sufficiently good 
idea of the shape of these organs, and of the hooks, circular or 
semi-circular, with which they are furnished. 
In Fig. 96 are represented, after the same author, two mem- 
branous legs of a large caterpillar, 
of which the hooks of the feet are 
fastened into a branch of a shrub. 
Caterpillars have from two to ten 
false lees, the scaly legs being always 
sixin number. The pro-legs, as the 
fleshy ones are called, are divided 
into hinder and intermediate. The 
former are two in number; the in- 
termediate are rarely more than 
eight in number. 
In the caterpillars which have the 
full number of legs—that is to say, 
sixteen—there are two empty spaces,

one between the legs and the pro-legs, formed by the fourth and 
fifth seement; the other, between the intermediate pro-legs and 
the anal legs, formed by the tenth and eleventh ring.
