ON KILLING AND 
a pin (PI. 1, fig. 6 and 7), or set out on small 
square pieces of card. The gum should be 
thinly spread, with a camel’s hair pencil, and 
the insect placed upon it, the legs, &c. being 
extended by means of a clean camel’s hair 
pencil. Field bugs, butterflies, moths, bees, and 
other winged insects, and also flies {Diptera) 
should be pierced through the thorax as re- 
presented in the plate, (l, hg. 2, 3, 4, 5.) 
All the flying insects should have their wings 
extended before they become stiflP, by means of 
braces, as shewn Plate 1, fig. 2, 3, 4, 5, the 
wings being elevated with the setting needles ; 
and the braces must remain several days on 
the insects, until their moisture is evaporated, 
and they are quite stiff. Another method is to 
have a piece of cork, with grooves for the body 
and legs, and the wings are then set flat with 
broad braces. Mr. Shuckard’s plan (by 
which he sets Hymenoptera most beautifully) 
is to raise a stage by means of two broad pieces 
of card, one to each pair of wings, and with two 
other broad pieces he confines the wings quite 
flat (PL 1. f. 2). As the underside of the wings 
of butterflies are not only very beautiful, but it 
being necessary to shew them to determine 
some of the species, those specimens whose 
upper wings are rubbed, should be selected for
