Philadelphia must be considered as belonging to the New Jersey fauna, as they 

 will certainly be found within the State with proper collecting, and in fact 

 specimens credited to these may in some cases have actually been captured on 

 New Jersey soil. Still, none of those are given for N. J., except where known 

 to have been collected at some point in the State." 



" Other species will certainly be found, especially in Jassidcc, Fulgoridcs,. 

 Aphididcc and Coccidce." 



Family CICADIDiE. 



Large species with transparent wings, 

 occurring on shrubs and trees, the males 

 making a shrilling sound during the day. 

 Includes the "Harvest flies" and "17- 

 year locust " as common species. 



In the adult stage they feed very little 

 or not at all, the larvae living from 1 to 

 16 years underground on the roots of 

 trees, growing very slowly and doing no 

 appreciable harm. 



Eggs are laid in slits made in trunks, 

 branches or twigs of shrubs and trees, and 

 this sometimes causes serious injury on 

 young or nursery trees. It is good policy 

 not to set an orchard the year a large brood 

 of the periodical Cicada is expected, nor 

 indeed the year before. If planting must 

 be done, do no pruning, that the insects 

 may find plenty of twigs in which to 

 oviposit, and these can be cut off after the 

 insects disappear and the tree shaped up.

C. septendecim Linn. "Seventeen 

 year Locust," or "Periodical Ci- 

 cada" : at intervals in all parts of 

 the State. There are four distinct 

 broods known in New Jersey, ap- 

 pearing during the last days of May and continuing to the early days of 

 July; a list of the broods has been published in the bulletins and reports 

 of the College Experiment Station.
