clear and distinctly veined, the antennae are placed be- 

 tween the eyes, and are of six or seven joints, and there 

 are three ocelli. 



Cicada Anglica (PL XII., fig. 1), the only English 

 species, is a rare insect, but there are smaller species as 

 beautiful and more common ; but while in England the 

 Cicadse do not form a conspicuous family, they are in 

 some foreign countries rendered prominent both by their 

 numbers and by the deafening noise which, when con- 

 gregated together, their combined efforts are capable of 

 producing. 



The Cicada is, as has been mentioned above (Introd. 

 p. 9), an eminently musical insect. In the Brazils it is 

 said to " sing till it bursts," an idea arising from the 

 number of split pupa-skins found under the trees 

 frequented by these insects, 



In America (where it is commonly called the Locust) 

 it is less esteemed for its powers, if we may judge by the 

 following extract: "One of your Spa-fields meetings 

 can give you a faint idea of their incessant and unmusical 

 cheering and noise. If Hogarth had known these 

 Locusts, he would have placed them about the ears of 

 his enraged musician. Knife-grinders and ballad-singers 

 would have been lost in their din."* 



The musical instrument is neither in the wing-cases, 

 as in the Cricket, nor in the legs, as in the Locusts ; but 

 is placed within the abdomen. 



The ovipositor of the Cicada is to the full as remark- 

 able an instrument as that of the Sawfly. It is a horny 

 borer (/, a) composed of two thick blades, which may be 

 called either saws or files (6, c, d) and which, running in
