PLATE LIV. 47 



Cicada Spumar'ia is not only common in this country, but is abun- 

 dant in every part of Europe. It frequents moft plants, but thofe 

 efpecially which exhale much moifture. The food of the Larva ap- 

 pears entirely of the vegetable kind, and confifts, for the moft part, 

 of the fuperabundant fluids which all plants tranfpire. 



*' The Cuckow-Spit, or Froth-Worm, is often found hid in 

 that frothy matter which we find on the furface of plants. It has an 

 oblong, obtufe body ; and a large head, with fmall eyes. The ex- 

 ternal Wings, for it hath four, are of a dufky brown colour, m,arked 

 with two white fpots : the head is black. The fpume in which it is 

 found wallowing, is all of its own formation, and very much refembles 

 frothy fpittle. It proceeds from the vent of the animal, and other 

 parts of the body ; and, if it be wiped away, a new quantity will be 

 quickly feen ejedled from the little animal's body. Within this fpume, 

 it is feen in time to acquire four tubercles on its back, wherein the wings 

 are enclofed: thefe burfting, from a reptile it becomes a winged 

 animal." 



The colour of the winged Infe6t is found to vary from a deep cho- 

 colate, to a very pale brown. It is taken in July and Auguft. 



It rarely ufes its wings for flight, as the hind legs are formed for 

 leaping; at one effort it will frequently bound to the diftance of two 

 or three yards.
