COLLECTING INSECTS.

leaving a bag before the holes, the insects will 
be easily captured when they make their exit, 
Platyrhinus latirostris has been taken in 
June in some abundance at Bristol, by strip- 
ping off bark on decaying willows, and tacking 
it somewhat loosely on again, and examining 
it every day. Timber yards should be well 
searched, and the holes probed or smoked ; 
but the insects found on or near foreign timber, 
should be kept separate and labelled. 
Beating Trees. Beating into a clap net 
or umbrella, has already been recommended, 
but a far more profitable mode may be adopt- 
ed, by two persons carrying a large sheet, while 
a third, wdth a pole twenty or thirty feet long, 
beats the higher branches of trees. Not only 
rare beetles and other insects are thus obtained, 
but also caterpillars, which only feed on the 
higher branches. From oaks the beautiful 
caterpillar of the purple emperor butterfly 
{Apatura Iris) may be beaten. 
Taking Caterpillars. A method of col- 
lecting caterpillars appeared in “ The New 
Times,” on the 24th of August, 1820 ; it might 
be tried in potatoe grounds in September, for 
taking the caterpillar of the death's head moth, 
{Acherontia Atropos) which, as well as many 
others, only feed by night, and conceal them-
