one row overlapping about one-fourth their length and alternating 
with those of the other row. The angular-winged katydid (1. reti- 
nerve (Burm.)) is smaller than the above species and more southern 
its range extending from New Jersey west through southern Indiana 
to Kansas and Nebraska and south ‘throughout the Southern States. 
Pterophytla camellifolia (¥.), the true katydid, is a large, green, 
robust form. The tegmina are dark green, leaflike, very broad, concave 
within, longer than the wings, and wholl y enclose the abdomen. The 
prosternum. is armed with two slender tapering spines. This broad- 
winged katydid dwells in small colonies in dense foliage of forest and 
shade trees and is more commonly heard than seen. Its call is begun 
soon after dusk and often continues till dawn and is the loudest of 
any member of the family. The known range extends from New 
England west to northern Illinois and south and west to North Caro- 
lina, northern Georgia, and central Kansas. The eggs are thrust by 
means of the ovipositor into crevices of loose bark or into soft stems 
of woody plants. The eggs are dark slate color, about 6.5 mm. long 
and 2 mm. wide, very flat, pointed at each end, and with the edges 
beveled off. 
Camponotus carolinensis (Gerst.) is not important, but it has a 
unique habit of rolling leaves into a nest in which it hides. It is 
medium sized, 12 to 15 mm. long, reddish brown above, yellowish white 
beneath, and wingless. The middle and hind pair of femora are 
mottled with dark brown. On each of three posterior dorsal segments 
of the abdomen is a dark-brown transverse bar. Its range extends 
from New Jersey west to southern Illinois and south to Tennessee, 
Mississippi, Georgia, and Florida. 
Famity GRYLLIDAE 
The Crickets 
The crickets are medium-sized, Jumping insects usually with long 
filiform antennae, three-jointed tarsi, and a spear-shaped ovipositor. 
The tegmina lie flat on the back and are bent down abruptly at the 
sides of the body. The wings may be fully developed, abbreviated, 
or wanting. The hearing organs when present are visible on one or 
both sides of the fore tibia. The calling organs on the male are lo- 
cated near the base of the dorsal surface of the t tegmina. 
The crickets are nocturnal, the males being shrill and loud singers. 
They are variable in habits, living in or on the ground, or in bushes 
and trees, and feeding on vegetable or animal matter. Although they 
are commonly found in countless numbers, they are not so serious pests 
as some of the other Orthoptera. The ‘tree crickets, which injure 
young branches with their oviposition scars, and the mole crickets, 
which occasionally cause some injury in nurseries, are the only crickets 
injurious to trees or shrubs. 
The mole crickets are quite different in appearance from the more 
typical crickets. Their front legs are fitted for digging, being greatly 
broadened and shaped somewhat like the front foot of a mole. Their 
hind legs are but httle enlarged and their ovipositors are not visible. 
They burrow in sandy soils or loose soils somewhat after the manner 
of moles. They feed on roots, earthworms, and on other insects. At 
night they feed near the surface, cutting off the plants.
