316 SETTING AND PRESERVING CRUSTACEA. 



lately to lose all kind of tear for their own personal safety, which, at 

 other times, is effectually secured by the reiterated evolutions of their 

 strong and rd\nd wings. So fearless indeed have I beheld them on 

 these occasions, as to climl) up and down the sides of the cage which 

 contained the dear object of their eager ]>ursuit, 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 .Septeml")er, the second and last brood of Caterpillars are 

 found : several species of Gryllus may also be taken in meadows and 

 marshy lands. 



OcTor.ER, November, December. — At the fall of the leaf insects 

 lx;come less numerous, but many of the llemiptcrous insects may 

 be foimd by beating the ferns and underwood in woods, also many very 

 beautiful Tinea? and Tortrices ; the aquatic insects will be found in 

 ponds pretty plentiful. Roots of grass, decayed trees, &:c. may again 

 be resorted to. 



Having now given an outline of ilie rules \\hich appear necessary 

 for the purpose of collecting insects, I shall proceed to their preser\'a- 

 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.'' 



SETTING AND PRESERVING. 



Crustacea. 



Mti/tod of collecthig. — Most of the Crustacea inhabit the sea; the 

 few tliat are found in frchh water are generally minute, Init highly in- 

 teresting : ponds, ditches, and marshes produce the latter in abund- 

 ance, and are 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 must 

 not omit to search diligently, by turning up stones, &c.; — Confervas 

 and Corallines, thrown on the ^hore after storms, frequently contain 

 many rare species, as also the pools left by the retiring tide on most of 

 the rocky coasts. By walking on the sea-bhore 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. 



Dinvtiunsjbr preserving Crustacea for Cahbiets. — Those species which 

 uihabit the sea should be suffered to remain for some hours in cold
