134 NATURAL ARRANGEBIENT OF INSECTS. 



are extended to the upper side of the abdomen, where 

 they have a considerable resemblance to those in the 

 pipes of an organ. The female cicada, however, is 

 entirely without this apparatus ; hence the old Greek 

 adage that the CicadcB were particularly happy, because 

 they had silent wives. Aristotle mentions them as de- 

 licious food ; but maccaroni lias long supplanted them 

 in the estimation both of the modern Greeks and the 

 Italians. 



(124.) The second division of this family is composed 

 of the CiRcopiN^, or jumping cicadas. They are all 

 of a very small size ; and very different, in their exter- 

 nal appearance, to the last: they have no musical powers; 

 and their long hinder legs are saltatorial, or adapted 

 for leaping. These little creatures are abundant in all 

 verdant situations during summer, particularly among 

 the foliage of trees, and high grass. The larva or 

 grub, as before observed, has the singular property of 

 producing a frothy liquid, precisely like human saliva, 

 in which its. soft tender body is secure, and in the 

 middle of which it constantly resides : hence the vulgar 

 names of cuckow spit given to the larva, and frog- 

 hopper to the adult or perfect insect : the ocelli, or 

 siinple eyes, in this group, are only two ; and the supe- 

 rior wings, called by some the elytra (we think im- 

 properly so), are nerved in a very different manner to 

 those of the true cicada. The genus Ledra is the 

 only one wherein the thorax is ornamented with horns 

 or other excrescences; and this appears to represent, in 

 its own circles, the Centronotidce. The foreign jumping 

 cicadas are innumerable, and are so little known, that 

 out of more than seventy species we discovered in 

 South America, we believe that not one half have been 

 described. 



(125.) The moth cicadas, or the Flatid.e, compose 

 the second great division or family of the tribe. As the 

 CicadidcB form the typical, so this constitutes the suh- 

 typical group ; and every one can perceive how beauti- 

 fully it represents the order of Lepidoptera. They are,
