THE INSECTS OF NEW JERSEY. 191 



the ovipositor is long, cylindrical, like a stout bristle, and this makes the 

 family easily distinguishable from the "Locustidse" in which the ovi- 

 positor is always blade-like. The field crickets are usually black or 

 brown, live in damp places in fields or meadows and jump readily if some- 

 what erratically. They are often common on cranberry bogs and are 

 believed to eat into berries, but I have never found them doing this until 

 after the berries were on the ground. 



The shrill music of the male cricket is well known and the "song" is 

 characteristic for each species. The eggs are usually laid in dry, sandy 

 soil late in fall, but some forms live as adults throughout the winter and 

 a few come into houses. As a rule they are omnivorous and occasionally 

 cannibalistic. 



The "tree crickets" are white or greenish as a rule, tending to yellowish 

 or light brown, and they occur on trees and shrubs as their popular 

 name implies. They are predatory in habit, feed largely on plant-lice and 

 are therefore beneficial. Their eggs are laid in the soft shoots of trees 

 and shrubs and some injury is occasionally done on fruit trees and berry 

 bushes, but this is slight as compared with the benefits derived from them. 



GRYLLOTALPA Latr. 



G. borealis Burm. Recorded from all sections of the State VII until frost. 

 The "mole cricket," so odd in its appearance that it attracts fre- 

 quent attention and is often sent in with requests for information. 

 Lives in burrows underground, in dams and along ditches, and has 

 been recorded as injuring potatoes. 



Columbia Scudd. is a long-winged form of the preceding and occurs 

 with it. 



TRIDACTYLUS Oliv. 



T. terminalis Scudd. Atlantic Highlands (Bt); Clementon V, 30 (Jn) ; 



Lucaston (GG); Bridgeport V, 20 (Haim) ; Ocean Co. (Sm) ; Laval- 



lette V (Vk); Anglesea IX (Dke). 

 T. apicalis Say. Staten Island VI, IX, on damp ground (Ds). 



ELLIPES Scudd. 

 E. minuta Scudd. Ocean City (Jn). 



CYCLOPTILUS Scudd. 

 C. squamosus Scudd. Lakehurst X, 3 (Ds). 



NEMOBIUS Serv. 



N. fasciatus De G. Throughout the State VII to frost. More common in 

 the pine barrens, but recorded as well from the hilly sections of the 

 north as along the beach strip to Cape May. 



N. vittatus Harr. This is a form of the preceding, in which the wings 

 are aborted. It is as widely distributed and has more northern 

 records; it also occurs commonly on cranberry boga.
