head is veiy large ; the body is high and convex, often com- 

 pressed laterally. The hind legs are thickened and enlarged, 

 adapted for leaping purposes. Some of the strangest shapes 

 among insects are found in this group. This is due to the great 

 development of the forehead, or vertex of the head, which is pro- 

 longed either angularly, or into a long snout-like process, as in 

 Fulgora, while in other species it is as long as the entire body. 



"The species of some genera, such as Flata Umbata, Phenax 

 variegata, Lystra auricoma and L. lanata, emit a waxy white 

 secretion, made into a fine white wax, which is much esteemed 

 in China and the P^ast Indies." (Westwood.) 



The Lantern-fly, Fulgora, attains an immense size when 

 compared with other Heniiptera, being between two and three 

 inches long. The head is large with a prolongation much 

 longer than the head, which is said by novices and some nat- 

 uralists, though doubted bj' others, to be luminous at night, 

 whence its name. The Fulgora lanternaria Linn, occurs in 

 Surinam, and F. (Hotinus) candelaria Linn, is found in China. 

 Mr. Caleb Cooke of Salem, who resided several years in Zan- 

 zibar, Africa, informs me that the Lantern-fly is said by the 

 natives to be luminous. They state that the long snout lights 

 up in the night, and in describing it, say ''its head is like a 

 lamp." {KeetcJuia kana-tah.) 



In Flata the base of the head is concealed by the front edge 

 of the prothorax, the front of the head is long and slender, 

 without any middle keel ; the wings are very broad and rounded. 



Anotia Bonnetii Kii'by is found, according to Fitch, on wil- 

 lows about the middle of September. Otiocerus Coquebertii 

 Kirby is found on beech and oak trees, and sometimes on the 

 grape-vine, according to Fitch. 



The genus Delphax has a very broad front, with sharp edges 

 and a forked keel along the middle ; the antennae are two- 

 jointed, the articulations long and thickened at the end. Del 

 phax arvensis Fitch is pale yellow, unspotted, with the elytra 

 and wings nearly pellucid. It is common in fields of wheat 

 early in June.
