tips. The tegmina are opaque and reddish at base, subtransparent dis- 
tally; the great hind wings are clear and transparent. This locust is com¬ 
mon in the South, where it sometimes assumes a migratory habit and 
becomes very injurious to crops. The leather-colored locust, S. alutaceum,

semi-transparent tegmina, and clear transparent hind wings, and the rusty 
locust, S. rubiginosum, with light dust-red body and opaque tegmina, are 
the common eastern representatives of this genus. Both are large and 
striking forms. 
The subfamily Tryxalinae includes a number of locusts distinguished 
by the sharp oblique sloping of the face, and in some cases by the much 
prolonged and pointed vertex (region of the head between the eyes). In 
the East the short-winged locust, 
Stenobothrus curtipennis (Fig. 174), 
recognizable by its short narrow 
wings, yellow under-body, and prom¬ 
inent yellowish hind legs with black 
knees, is a common example of this 
group. It likes to hide among tall 
grasses, where its sprightly tumbling

locust, Chloealtis conspersa (Fig. 175), is an abundant species through¬ 
out the East. It is light reddish brown sprinkled with black spots, 
and has pale yellowish-brown tegmina with many small dark-brown spots, 
the wings being clear; it is about three-fourths of an inch long. The 
males have the sides of the pronotum shining black. This locust lays its 
eggs in rotten stumps or other slightly decayed wood. Blatchley discovered 
a female in the act of boring a hole for her eggs in the upper edge of the 
topmost board of a six-rail fence. One of the most grotesque of all the 
locusts is a member of this subfamily named Achurum brevipenne. The 
body is very long and thin, measuring an inch and a half in length by one-
