322 ORTHOPTERA OF NOVA SCOTIA. PIERS. 



I did not succeed in capturing, was seen on a fir tree. In 

 the vicinity were large white pines and spruces. At the 

 time I heard about a dozen others, presumably of the same 

 species. Their note was chiefly a very short zi'p, but unlike 

 that of S. pistillata. These two specimens agree fully with 

 Scudder's description and plates in his paper on The Orthop- 

 teran Group Scudderige (Proc. Am. Acad. Arts and Sc, 

 Bost., p. 33, 1898), the form of the supra-anal spine leaving 

 no doubt whatever as to the determination.* Their measure- 

 ments have been given on page 320. I did not deter- 

 mine the specimens until the spring of 1916, and in 

 going to the same locality in the following summer, I only 

 happened to find S. pistillata, but further search will without 

 doubt show it is still there. 



This form is no doubt rare or quite uncommon about 

 Halifax, and C. B. Gooderham informs me that he has 

 never seen it near Truro, Col. Co., or in the western counties 

 of Nova Scotia, and there is no specimen in the collection of 

 the Agricultural College, Truro. Still we would expect it 

 to be more related to the fauna of our Transitiou region than 

 to that of the Canadian region of eastern Nova Scotia. In 

 New England it is everywhere common. It probably appears 

 later than S. pistillata, and should be met with from August 

 to October. In New Jersey it occurs usually in pine barrens, 

 and in Indiana is mostly seen on low bushes and trees about 

 the margins of thickets and along fence-rows, while in the 

 prairie country to the north it frequents coarse grass and 

 weeds in company with S. pistillata. 



The characteristic keelless, deeply and widely forkel 

 and much swollen end of the supra-anal spine of the male 

 will very readily distinguish it, on careful examination with 

 a lens, from S. pistillata and S. curvicauda horealis. Females 

 may be separated from tliosc of »S. pistillata by the propor- 

 tionately narrower wing-covers of furcata; and the propor- 

 tionately narrower ovipositor of the latter may help in
