An Injurious Grasshopper at Ridgeway, New Jersey 
(Orth.). 
By Ws. T. Davis, New Brighton, Staten Island, N. Y. 
In the last list of the Insects of New Jersey the grasshopper 
Dendrotettix quercus Riley is reported from Bamber, collected 
by Mr. Daecke, August 17th. This is said to be the only 
record of the species in the Eastern United States. 
Dendrotettix did damage to the oak trees at Ridgeway, N. 
J., in 1910. A few were found on August 16, 1910, about a 
mile west of Lakewood, and last year they were very common 
on the oaks about Ridgeway and north to where the road to 
Lakewood crosses Toms River. A single specimen was dis- 
covered on a post oak at Lakehurst on August 15, 1911, so the 
known range of the insect is from Bamber to Lakewood, a 
distance of about twelve miles, and westward for a few miles. 
The damage has been so great that the many defoliated trees 
near Ridgeway are noticeable from the windows of a moving 
train. The gayly colored grasshoppers are more common 
on the white oaks, though they eat the foliage of scarlet oaks 
and other members of the red oak group. Some of the scar- 
let oaks near Ridgeway have been hard pressed by enemies. 
They support many large woody galls of Callirhytis punctata 
on their limbs; they have had thousands of eggs of the seven- 
teen-vear cicada laid in their branches, which have caused the 
ends of many of them to break off and die, and lastly the trees 
have been defoliated by the grasshoppers. 
Mr. W. DeW. Miller, of the American Museum, and I, 
counted on the trunks of some trees, as many as forty grass- 
hoppers, usually slowly making their way up to what re- 
mained of the foliage, and the excrement of the grasshoppers 
on the limbs fell with a rain-like patter on to the dry leaves 
beneath. Some of the grasshoppers were fully winged and 
others were apterous. Individuals between these two states 
were not common. We have before noticed this in other Or- 
thopterous insects. Nature either prepares them for flight or 
the reverse; there is hardly a half way condition. In addition
