METHOD OF COLLECTING, &c. 193 
insects, the collector must beat the branches of trees 
into his folding gauze net, as also hedges, nettles, 
and other plants, on which these larvee feed, or 
to which many of the pups are suspended by the 
tail. 
In searching for moths which fly by night, the 
London collectors have a lantern constructed with 
a concave back, and provided with a reflector be- 
hind. This lantern is fastened round the body of 
the lepidopterist, about the region of the stomach, 
by means of a belt. The fly net should be held 
open in front by the collector, when all those noc- 
turnal flying moths will be entrapped which come 
within the influence of the light, to which they are 
naturally attracted. In hot and close summer 
evenings, if a candle is placed on the table of a 
summer house, or in other rooms, with the windows 
open, it will be found that many of the night 
flying lepidoptera will be thereby attracted. 
When taking lepidopterous insects by means of 
forceps, they should he as widely expanded as pos- 
sible, and the insect should be approached with 
great caution. When the entomologist has ap- 
proached sufficiently near, the instrument should 
be quickly closed on the animal, including the leaf 
on which it is settled. When the prey is secured, 
a gentle pressure with the finger and thumb is ap- 
plied to the thorax below the wings, which soon 
kills it.
