134 HAUSTELLATA. — LEPIDOPTERA. 



Humming-bird." It is far from uncommon, and in some places it 

 abounds. During two sliort visits at Dover, in August, 1818 aud 

 1819, I observed it in great abundance in the winged state, and in 

 June of the latter year, accompanied by the late Mr. Blunt, we 

 found the larvse in profusion beneath the cliffs : I have also taken 

 the insect plentifully at Hertford, and occasionally at Ripley. There 

 are usually three broods in the year, appearing respectively at the 

 end of April, June, and August; some of the latter have been 

 Iviiown to hybernate. " Common near Ely, Bottisham, &c." — Rev. 

 L. Jcnyns. " Not very common near York ; but more abundant

AntcnncB thickening from tlie base nearly to the apex, and from thence to the

Sesia differs from Macroglossa in the transparency of the disc of 

 its wings, and in having the body rather short, ovate, and thickly 

 clothed with long hair, as well as by the form of the antennae, and 

 several minor characters. They frequent woods and meadows by 

 the sides of plantations.
