Some largeinsects, and especially female moths, whose sizeprevents the use of the ordinary cyanide bottles, are difficult to these, fluttering may be prevented by the use of chloroform, or theymay be killed by puncturing the thorax or piercing the body longitudi-nally, with a needle dipped in liquid cyanide, or oxalic acid. A longbottle with a needle thrust into the cork may be kept for this purpose:but the needle must be of ivory or bone, as those of metal are corrodedand eaten by the liquids. For killing small and delicate, moths which have been bred. I findnothing more handy than chloroform. They may be caught in turned. FIG. 89.—Chloroform bottie with brush.
