ivory climbing cricket, JEJcanthus niveus, Sew. The male 

 is ivory white, with very broad, transparent wing-covers, 

 crossed by from three to five oblique raised lines. In the 

 female the wing-covers are longer and narrower, and of a 

 pale green color. The antenna? and legs are long and slen- 

 der, the hind thighs not being so stout as in the ground 

 crickets. The shrilling of the species is more sustained 

 than that of Gryllus, the notes running together like the 

 roll of a drum, swelling and decreasing alternately. They 

 commence shrilling about the first of August, and continue 

 until the frosts of Octobor put an end to their existence. 



The eggs are deposited in the stems of plants. The in- 

 sect is sometimes very injurious to raspberry canes and 

 grape vines, on account of its piercing them with its ovi- 

 positor, causing them to wither and die. 



Grasshoppers (Locustari^e). 



These insects may, with few exceptions, be recognised 

 by their long and slender legs, and by their extremely long 

 bristle-formed antennae. In the winged species, the wing- 

 covers slope downwards at the sides of the body and over- 

 lap a little on the back near the thorax. The ovipositor is 

 generally long, flattened at the sides, and curved like a 

 cimiter. 



The shrilling of some of the soul hern species is quite 

 powerful, and where the insects are very abundant the 

 noise is sometimes unpleasantly loud ; but in these northern 

 regions the notes of our grasshoppers are weak, nor are the 

 insects sufficiently numerous to attract much attention. 



At the head of the family, systematists place a group of 

 wingless forms represented in Canada by two species, one 

 restricted to the North- West, the other apparently common 

 in Ontario and Quebec. 



Centhophilus maculatus, Harris. This curious insect is 

 rather strongly built, with stout hind thighs ; the back is 

 arched and has a smooth, shiny appearance, as if varnished. 

 Its general color is brown, thickly covered with spots of a 

 lighter color. Wings entirely absent, ovipositor rather
