416 OBSERVATIONS ON INSECTS AND VERMES. 



I cnce saw a swarm of these insects playing up and down over 

 the surface of a pond in Denn Park, exactly in the manner de- 

 scribed by this accurate naturalist. It was late in the evening of 

 a warm summer's day when I observed them. MARKWICK. 



SPHYNX OCELLATA. 



A vast insect appears after it is dusk, flying with a humming 

 noise, and inserting its tongue into the bloom of the honey-suckle ; 

 it scarcely settles upon the plants, but feeds on the wing in the 

 manner of humming birds. WHITE. 



I have frequently seen the large bee moth, sphinx stellataruntj 

 inserting its long tongue or proboscis into the centre of flowers, 

 and feeding on their nectar, without settling on them, but keeping 

 constantly on the wing. MARKWICK. 



CONVOLVULUS HAWK-MOTH.
