96 OF THE SENSES OF 
the collection of the Portsmouth Philosophical Society, 
T had procured a variety of larvee, (the insects thus 
obtained being generally in a better condition than 
those taken by the net.) They in due time passed 
into the pupa ; and the first which emerged, was a 
female Sphinx Convolvuli. On going into my study

On lifting it up, it ran up my coat, and several times 
round the collar, before I could place it in safety. I 
went from thence immediately into my garden, to

coat, where the female had previously been. 
« A fter this, another female of the same species had 
been produced ; three males found their way into my 
study down the chimney, there being no other mode 
by which they could obtain entrance ; and one of

males rushed in, and instantly sought the females. 
« T state these facts just as they occurred. They

females emit an odour perceptible to the delicate
