ORTIIOPTEHA OF NOVA SCOTIA. — PIKKS. 'Mo 



monly, at least from Tatamagouche, on Northuml^erland 

 Strait, south-westward throughout the Annapolis Valley to 

 Yarmouth. No data is available regarding its occurrence in 

 Cape Breton Island. 



It is found upon the foliage of clusters of shrubs and low 

 bushes, chiefly Speckled Alders (A. incana), in or near some- 

 what swampy or damp ground in the vicinity of land which 

 is more or less cleared. Usually there is only one male on 

 each bush. On the juices of these shrubs it feeds with the 

 aid of its sharp mandibles; and its eggs, instead of being 

 deposited in the earth or in twigs or grass-stems, etc., as 

 is usual with most of the Orthoptera, are glued in double 

 rows like flattened hemp-seeds, to the outer surface of 

 slender twigs or are inserted in the edges of leaves. All 

 the members of the Phaneropterince agree in this manner of 

 oviposition. S. pistillata is usually extremely slothful, 

 although the male occasionally flies some distance from bush 

 to bush, but if in doing so he comes to the ground, he generally 

 falls most awkwardly on his side, if detected while on a bush 

 he can usually be easily taken with the fingers, although 

 occasionally when approached he will suddenly drop to a 

 branch beneath. Females are excessively secretive and are 

 very rarely observed, one reason being that the male only 

 proclaims his location by loud calls. Considering the great 

 difficulty of determining the species to which females belong, 

 most students perhaps are quite thankful for this. 



The Katydids, because of their green colour, leaf-like 

 form, and very slow movements, are extremely difficult to 

 distinguish from the leaves among which they are. The best 

 way to ascertain their exact location is by taking rough cross- 

 bearings. First listen for their call-note and so get the 

 bearing, and then go around until approximately at a right- 

 angle with the former position, listen again for the call, and 

 thus obtain another bearing which intersects the first one. 

 Then on going cautiously to the spot indicated by these 

 cross-bearings and listening once more for the guiding note,
