middle femora of the male much swollen, and with a sharp 

 spine at the apex of the under side of both the middle and hind 

 femora, which is less prominent in the female. 



One species of this genus occurs throughout the northern 

 United States east of the Rocky Mountains and is represented in 

 Connecticut. 



D. femorata Say. Northern Walking-stick. Plate VII, 7. 



Color of the male usually greenish brown, sometimes almost 

 entirely green. Head yellowish, with three more or less distinct 

 longitudinal fuscous stripes. The female more often grayish 

 brown, more or less mottled with lighter specks. The male is 

 readily distinguished by the more slender body, the less dilated 

 fore femora, the more swollen middle femora, and the stouter 

 spines near the tips of the middle and hind femora. The middle 

 femora of the darker males are banded with lighter color. 



This curious insect is probably well distributed throughout 

 the state and is sometimes locally abundant, but the ordinary 

 observer will seldom see more than one or two specimens in a 

 year, owing to its protective resemblance to twigs and its habit 

 of remaining quiet for long periods. It is often taken in sweep- 

 ing low bushes, the hazel apparently being one of its favorite 

 food plants. The northern walking-stick is the most common 

 species in the United States and the only one of economic im- 

 portance. It has been recorded as defoliating considerable tracts 

 of woodland, oak and wild cherry usually being attacked first. 

 Ordinarily it is not abundant enough to do much damage. Burn- 

 ing the ground in the fall to destroy the eggs is the remedy 

 suggested. 



SALTATORIA. 



The Orthoptera belonging to this sub-order have the hind 

 pair of legs greatly enlarged and fitted for leaping. In the 

 winged forms the males are provided with calling organs, and 

 both sexes possess auditory or hearing organs. The wingless 

 forms lack both the calling and hearing organs. Three families
