128 ORTHOPTERA. 



Eggs laid in a longitudinal series in raspberry canes, 

 causing the death of that part of the plant which is 

 beyond the punctures. The eggs are laid in the au- 

 tumn ; the young crickets appear (at Ithaca) during 

 the month of June (June 15th, 1873); the perfect in- 

 sect may be found early in September (Sep. 9th, 1873). 

 This species is predacious, feeding upon plant-lice and 

 eggs of insects. Prof. Riley states that females ovi- 

 posit in the twigs or canes of the grape-vine, apple, 

 peach, blackberry, white-willow and soft-maple, as well 

 as those of the raspberry. (3, V., 120). 



LOCUSTARI^ (Green or Long-horned Grasshoppers). 



Saltatorial Orthoptera with long, slender antennae ; 

 wings, when at rest, slanting like a roof; tarsi four- 

 jointed ; ovipositor, generally long, compressed, sword 

 shaped. 



The Long-horned Grasshoppers are mostly of a 

 green color, their wings often resembling leaves. 

 Like the crickets, they are chiefly nocturnal, solitary, 

 phytophagous insects. They live on grass and other 

 herbaceous plants. Their eggs are laid either in the 

 ground or in various parts of plants. A few of the 

 larger species, called Katydids, inhabit trees and 

 shrubs. (2, 155 ; 3, VL, 150). 



One species of Katydid, Microcentrum retinervis 

 Burm. attaches its eggs externally in a double row to 

 twigs. From eggs of this insect received from New 

 Jersey, I have bred a Chalcis-fly, Antigaster mirabilis 

 Walsh. (5, IL, 368). 



Several genera, belonging to this family, are wing- 

 less. Ceuthophilus maculatics Say is a common, wing- 

 less species, found under stones.
