The southern mole cricket (Scapteriscus acletus R. & H.) is some- 
what more slender and pinkish buff in color. It is recorded from 
Georgia, Texas, and other Southern States. 
The tree crickets are an interesting group of small, delicate, pale- 
colored crickets that are definitely “arboreal, Injury to trees and 
shrubs is caused by the females, which chew small pits in the bark and 
then drill into the holes with their Ovipositors to lay their eggs. This 
injury causes the branches to break. Fulton (174) reported ‘that tree 
crickets also fed on aphids and scale insects, as well as on foliage and 
fruit, and for that reason may be considered beneficial at times. 
The tarsi are three-jointed, the second segment being small and 
compressed. The legs are very slender and in Oecanthus the hind 
tibiae are armed with a double row of slender spurs interspersed with 
toothlike spines. The tegmina of the males are very broad and flat and 
he in a horizontal position over the abdomen. The tegmina of the 
females are narrow and wrapped closely about the body. The song 
of the male, which seems to attract the female, is produced by a minute 
rasp on the inner side of the forewing which is scraped by a structure 
on the inner edge of the opposite wing. On the metanotum of the 
male isa elandular secretion which attr acts the female. ‘They over- 
winter 1n the egg stage. One generation is produced annually. 
The snowy tree cricket ( Oecanthus niveus (Deg.)) is widely dis- 
tributed throughout the United States. It is very pale ¢ ereenish white 
with a single black spot on each of the first two antennal : seoments. It 
inhabits tr ees, bushes, and orchards, preferably in the open. The eggs 
are deposited singly in branches. 
Ocecanthus angustipennis Fitch is widely distributed in the eastern 
part of the United States. It is pale greenish white with a J-shaped 
mark on the basal segment of the antenna. The eggs are deposited 
singly in the branches of trees. 
Oecanthus exclamationis Davis is similar in appearance, habits, and 
range to the preceding species but can be distinguished by the mark 
on the basal segment of the antenna being club- shaped instead of like a 
letter J. 
The black-horned tree cricket (Oecanthus nigricornis nigricornis 
Wlkr.) is widely distributed in the United States. It is greenish-yel- 
low with the head and pronotum either wholly black or with three 
more-or-less distinct, lengthwise, black stripes. The eggs are depos- 
ited in rows in canes of raspberry and blackberry and the branches of 
trees, and it is quite destructive in certain berry-growing regions. The 
four -spotted tree cricket (Oecanthus nigricornis quadr ipunctatus 
Beut.) is a subspecies that has two distinct spots on each of the two 
basal segments of the antennae. The ventral surface of the abdomen 
is pale r ather than dark. 
Oecanthus pint Beut., the pine tree cricket, has been found only 
in the Eastern States. The head, thorax, and antennae are reddish 
brown. It lays its eggs about 3 mm. apart in regular rows in pine 
bark. 
Oecanthus latipennis Riley occurs in the eastern part of the United 
States. The male is greenish white and the female is pale yellowish 
green. The basal joints of the antennae are pinkish. It deposits from 
4 to 12 eggs ina single hole in the smaller twigs of shrubs and vines. 
Neowabea bipunctata (Deg.) is widely distributed in the East but
