form types, has the apparently fleshy mamille that pro- 
ject from its sides and back crowned with little hairy red 
globes, which give the animal a most singular and unique 
appearance *. 
Having thus described some of the principal modes in 
which the All-wise Creator has decked and defended these 
creatures with hairs, I shall next give you a short ac- 
count of the spines with which he has armed others. 
The spinous larve are principally lepzdopterous, and 
more particularly conspicuous in some tribes of butter- 
flies, though some saw-flies and Diptera are also di- 
stinguished by them. Vanessa Io”, Atalanta and Urtice, 
Argynnis Paphia, Urania Leilus, and many others are 
clothed with long sharp points, which claim the deno- 
mination of spines, rather than that of hairs or bristles ; 
being horny and hard, and so stiff at the point as rea- 
dily to pierce the skin. ‘Those of the last-mentioned 
species, Madame Merian says, are as stiff as iron-wire‘. 
They are sometimes entirely simple, and look like spikes 
rather than spines, as in the caterpillar of Limenitis ? 
Amphinome and Morpho Menelaus*; but ordinarily they 
are beset with hairs, or more commonly with shorter 
spines, which often give them the appearance of plumes, 
as in Urania Leilus just mentioned: sometimes these 
lateral spines are so long as to have the appearance of 
a branch of a tree; this is strikingly the case with a small 
caterpillar which Captain Hancock brought from Bra- 
zil; its body is so thickly planted with spines of this de- 
scription, that it absolutely wears the appearance of a 
forest or thicket in miniature. A singular circumstance
