which has been proposed for it. This species is remarkable for the 

 long time required for it to attain its maturity. The eggs are laid 

 in the twigs of various trees; the female makes a series of slits in 

 the twig, into which th are placed. Sometimes thi 



occurs in such great numbers that they seriously injure small fruit- 

 trees, by ovipositing in the twigs and smaller branches. The lai 

 hatch in about six weeks. They soon voluntarily drop to the 



:nd. where they bury themselves. Here they obtain nourish- 

 ment by sucking the juices from the roots of forest and fruit tr 

 And here they remain till the seventeenth year following. They 

 emerge from the ground during the last half of May, at which time 

 the empty pupa-skins may be found in great numbers, clinging to 

 the bark of trees and other objects. The insects soon pair, the 

 females oviposit, and all disappear in a few weeks. 



More than twenty distinct broods of this species have been tr 

 out; so that one or more broods appear somewhere in the United 

 States nearly every year. In mail}' localities, several broods coexist ; 

 in some cases there are as many as seven distinct broods in the same- 

 place, each brood appearing in distinct years. There is a variet 

 the species in which the period of development is only thirteen years. 

 This variety is chiefly a Southern form, while the seventeen-} 

 broods occur in the North.

This family is remarkable for certain exotic forms which it con- 

 tains. Chief among these is the great Lantern-fly of Hra/.il, which is 

 figured in many popular works on insects. Scarcely less strange
