STATES OF INSECTS. (Ligg.) cp 
enemies. I shall consider them under two views : jist, 
as depositing their eggs in groups, whether covered or 
naked ; and secondly, as depositing them singly. 
gs in groups are first to 
be considered. I shall begin with those that protect them 
1. Those that deposit their eg 
with some kind of covering. 
I have already mentioned in a former letter? the 
silken bag with which Lycosa saccata, a kind of spider, 
surrounds -her eggs, and in whieh she constantly car- 
ries them about with her, defending them to the last ex- 
tremity. Many other spiders, indeed nearly the whole 
tribe, fabricate similar pouches, but of various sizes, 
forms, texture, and colours. Some are scarcely so big 
as a pea, others of the size of a large gooseberry ; some 
globular, some bell-shaped ; the pouch in which the eggs 
of some spiders are inclosed resembles a cocoon; one 
shaped like a bell, suspended by a footstalk, is described 
and figured by De Geer®, and I have a similar one in 
my own cabinet: others, the genus Thomisus in parti- 
cular, are depressed like a lupine; some of a close tex- 
ture like silk; others of a looser fabric resembling wool : 
some consisting of a single pellicle, but most of a double, 
of which the interior is finer and softer * ; some white; 
others inclining to blue; others again yellow or reddish ; 
most of them are of a whole colour, but that of Epeira 
Jfasciata is gray varied with black 4. And while the parent 
spider of some kinds (the Lwpz) always carries her egg- 
bag attached to her anus, others hold them by their 
palpi and maxillz ; and others suspend them by a long
