SETTING AND PRESERVING CRUSTACEA. 
iutely to lose all kind of fear for their own personal safety, which, & 
other times, is effectually secured by the reiterated evolutions of their 
strong and rapid wings. So fearless indeed have 1 beheld them ° n 
these occasions, as to climb up and down the sides of the cage which 
contained the dear object of their eager pursuit, in exactly the same 
hurrying manner as honey bees, which have lost themselves, climb up 
and down the glasses of a window.” At the latter end of August, and 
the whole of September, the second and last brood of Caterpillars are 
found : several species of Gryllus may also be taken in meadows and 
marshy lands. 
October, November, December. — At the fall of the leaf insects 
become less numerous, but many of the Hemipterous insects may 
be found by beating the ferns and underwood in woods, also many very 
beautiful Tine* and Tortrices; the aquatic insects will be found in 
ponds pretty plentiful. Hoots of grass, decayed trees. See. may again 
be resorted to. 
Having now given an outline of the rules which appear necessary 
for the purpose of collecting insects, 1 shall proceed to their preserva- 
tion, which, above all, will act as a particular incitement to the early 
collector, who, it is supposed, “ would feel very little pleasure at the 
recollection that all the fruits of his toil in one season would be de- 
stroyed in the next; or at best, that his specimens would only retain a 
wretched vestige of their original perfection.”

Crustacea. 
Method of collecting. — Most of die Crustacea inhabit the sea ; the 
few that are found in fresh water are generally minute, but highly in' 
teresting : ponds, ditches, and marshes produce the latter in abund- 
ance, and arc common near London ; they are taken with the water- 
net, and may be preserved as directed hereafter. 
In searching for Crustacea on the sea-shore, the Entomologist roust 
not omit to search diligently, by turning up stones, & eft. ; — Confer?® 
and Corallines, thrown on the shore after storms, frequently contain 
many rare species, as also llie pools left by the retiring tide on most of 
the rocky coasts. By walking on the sea-shore after heavy gales of 
wind many Crustacea will be found: he must also take every opportu- 
nity of examining the fishermen's nets, and the refuse thrown away 
by them. Empty shells should also be examined, as they frequently 
form a habitation for these animals. 
Directions for preserving CrustaccaJ'or Cabinets. — Those species which 
inhabit the sea should be suffered to remain for some hours in cold
