hymenopterous parasite, Mesitiopterus kahlit Ashmead; various 
predators such as crows, robins, and other birds; and dry weather 
during the period of egg hatch are important natural control 
factors (775). 
Several other species of walkingsticks also occur in eastern 
United States. The two-striped walkingsticks, Anisomorpha bupres- 
toides (Stoll.), is found in the Deep South, typically in oak stands 
growing on excessively drained, sandy soil in Florida. Eggs are 
laid in groups of 8 to 10 eggs, each in small pits dug in the soil. 
A. ferruginea (P de B.) feeds on various trees and shrubs from 
southeastern Nebraska and Arkansas through the high country to - 
Georgia and the Carolinas. Diapheromera velit Walsh and D. 
blatchleyi (Caud.) feed on grasses and tall shrubs. D. vel occurs 
on the Great Plains; D. blatchleyi, from the Great Plains to the 
Atlantic Coast. Megaphasma denticrus (Stal.), the giant walking- 
stick, sometimes attains a length of 150 mm. Its habits are similar 
to those of D. femorata, but it is apparently never abundant 
enough to be injurious. 
FAMILY ACRIDIDAE 
SHORT-HORNED GRASSHOPPERS 
This family contains most of the well-known grasshoppers, 
many of which are frequently very destructive to agricultural 
crops. Ordinarily, they are not very injurious to trees, but they 
may be seriously damaging during outbreaks. Young trees in nur- 
series, shelterbelts, and plantations are particularly vulnerable, 
especially on the Great Plains, in the upper Mississippi Valley, 
and in the Lake States. The adults are distinguished by their 
short filiform, or three-jointed, clubbed, antennae; short and in-
