Eeplying to inquiry of the insect infesting wheat in York county, Penn., 

 is given : its operations in Europe; its history in the United States; is 

 a southern species, and rare in the State of New York; notice of the few 

 occasions in wliich it has been observed in this State, in museums at Albany 

 and Geneva, and in grain stores — probably not attacking grain in the field; 

 a Catolaccus parasite reared from infested corn; number of broods varying 

 with the latitude and temperature, from two to eight; broods in Pennsyl- 

 vania; the grain heated by the gnawing of the larvae; the flour produced 

 from infested wheat unwholesome and producing disease; bisulphide of car- 

 bon remdy for the insect when within the grain.

The Periodical Cicada. (Country Gentleman, for March 23, 1893, 

 Iviii, p. 226, col. 3 — 20 cm.) 



Replying to inquiries from Plainfield, N. J. — This will not be a locust year 

 in New Jersey or in New York. Next year an extensive brood will appear 

 along the Hudson river valley, and in parts of Connecticut, New Jersey, 

 Pennsylvania, Maryland, and Virginia. It probably will not be abundant in 

 the vicinity of Plainfield, N. J. Fruit-trees are often injured by it, nurseries 

 and young orchards especially. Its injuries through oviposition cannot 

 be prevented by applications to the trees. It may be more easily killed before 

 it becomes winged; and the mature insect may be driven from orchards by 

 taking advantage of high winds.
