strong spjnes. Male cerci are curved with tips pointed, these are used as clasping or- 

 gans. The notch in the supra-anal spine is broader than deep; the lateral processes 

 tapering distally being sub-triangular, not broadly rounded; the ventral flanges are 

 deeper at the base than at the tip. Sub-anal plate strongly upcurved. Tegmina and 

 wings of female are shorter than in the male and have no stridulating field. 



This species appears to be rather common in different parts of the province, and 

 has been taken in company with S. cuivicauda boiealis. Its call is often heard during 

 the daytime, but it is mostly heard on a warm night during the latter part of the sum- 

 mer when in some localities they appear to be in every shrub and on every blade of tall 

 grass. They are accomplished ventriloquists and are difficult to find by their call.

This insect is somewhat smaller and more compact than S. pistillata but resembles it 

 very closely in structure and color. The main points of difference between them are 

 given below. 



The lateral carina of pronotum more rounded. The tegmina very much narrower 

 with less prominent veins; the distal end less broadly rounded. The stridulating field 

 is also much smaller. The notch in the supra-anal spine is deeper with the lateral pro- 

 cesses broadly rounded; the ventral flanges do not reach the tip as in S. pistillata. 



The females of the two species resemble each other very closely but the tegmina of 

 the present species are much narrower and the eyes decidely larger than in the former 

 species. 



Like S. pistillata. this insect appears to be fairly common. It has been taken in com- 

 pany with the former and in about equal numbers in different parts of the province. 



cudderia furcata furcata (Brunner). 



The members of this species closely resemble those of the species just described, 

 and may easily be mistaken for them at first glance. The following chief differences, 

 however, can be noted. 



The body is slightly more robust than in the former species and the tegmina are 

 slightly longer especially in the males and are proportionately narrower. The hind legs 

 are somewhat longer and the femora stouter. The notch in the supra-anal plate of the 

 male is deeply rounded, with the lateral processes very much swollen; the ventral flan- 

 ges are absent. This readily distinguishes it from the other species. 



The ovipositor of the female is much smaller and not so abruptly upcurved. 



Mr. H. Piers of the Provincial Museum of Halifax has reported taking this insect 

 in the vicinity of Halifax.
