Lift each larva carefully by means of a strip 

 of cigarette paper. Drain off the excess of forma- 

 lin, and place with the greatest care in absolute 

 alcohol. Allow the specimen to remain for at 

 least ten minutes in alcohol. 



Remove with cigarette paper to a watch 

 glass containing oil of cloves. With cigarette 

 paper transfer to a slide. Remove excess of oil 

 of cloves, mount in a large drop of balsam, taking 

 care that the dorsum of the larva is upwards. 



If great care is taken not to detach the hairs 

 by handling, the larval characters are beautifully 

 displayed in this way.
