ble of any locust the writer has ever observed. Although a 

 persistent singer, the notes become inaudible only a few feet 

 away. In the fields they are quite lost amidst the sounds of 

 rustling foliage, the chirpings of crickets, etc. 



The notes of Xiplridiiim brcvipcnne are very brief and much 

 more hurried in their delivery than those of X. fasciatum. In 

 this respect they approach more nearly the dainty stridulations 

 of X. nemorale Scudd. In the song of X. brevipenne usually 

 only one or two almost inaudible staccato lisps precede one, 

 two or even three of the brief, faint phrases, tseeeeeee-tseeeeee. 

 The phrases tseeeee are of much longer duration in the song of 

 X. fasciatum, and are rarely heard without the preceding stac- 

 cato lisps which are of indefinite number. 



Graphically represented, the notes of an individual X. brevi- 

 penne were as follows: . .- 



Gryllus pennsylvanicus Burm., at this season may be found 

 in great numbers crawling over the grassy upland fields chirp- 

 ing incessantly in the sunshine. Its notes in New England are 

 always a brief intermittent musical chirp-chirp-chirp. 



Nemobins fasciatus (t'ittatus') DeG. occupies the grassy fields 

 and pastures everywhere, trilling incessantly during the hours 

 of sunshine. In some localities the trill is very brief and 

 shrill tiiii-tiiii-tiiii. In others the trill is exceedingly high and 

 indefinitely prolonged ti-ti-ti-ti-ti-ti-ti-ti. The prolonged tril- 

 lers appear to be confined almost entirely to dry, grassy, up- 

 land situations. The intermittent singers seem to prefer low, 

 wet grounds. This distribution is rather clearly defined.
