vertical. The mesosternal lobes are separated by a space several times 
as wide as long in both sexes; the metasternal lobes are separated by 
a space a little longer than wide in male and female. The tegmina 
and wings are well developed, not quite equaling or somewhat longer 
than the abdomen. The posterior femora have three, usually well- 
marked, subtriangular or irregular brown spots on the upper face. 
The posterior tibiae are red or yellowish with the apical spurs on the 
inner side much elongated and very unequal. We have but one species 
in this genus. 
Ageneotettix scuddert Bruner 
Ageneotettix scudderi is a beautiful little insect which has been 
noted at a number of places but which, owing to its habit of dropping 
to the ground when alarmed, is commonly overlooked. Blatchley (The 
Orthoptera of Indiana, p. 249) has said that “when disturbed it leaps 
vigorously and without noise for several times, then settling down 
upon a sandy spot will allow a close approach.” This is true when 
it is found, as is often the case, among low or scanty vegetation, but 
we have noted that when in tall or close grasses it will simply dive 
headlong to the ground and crouch there among the stems. Certain 
forms of this species have a very distinct light-colored median line on 
the dorsum as has been noted in Arphia and Tettix. We have taken 
adult specimens of this species at Fergus Falls as early as July 12. It 
has been taken at Fergus Falls, Granite Falls, Mankato, Northfield, 
Albert Lea, Mahtomedi, Glyndon, Detroit, and Ada, and will doubtless 
be found in open places through most parts of the State, save possibly 
in the extreme north. 
SUBFAMILY OEDIPODINAE 
The insects of the subfamily Oedipodinae have the prosternum 
unarmed, the face nearly vertical, and the head rounded at the vertex. 
The fastigium of the vertex always slopes strongly downward, the 
foveolae are usually present but obscure; the antennae filiform, never 
strongly modified, though the basal joints or one edge may be some- 
what modified in some genera. The eyes are less elongate than in the 
Tryxalinae, being generally shorter than the infraocular portion of 
the genae. Dorsum of the pronotum usually considerably widened 
posteriorly ; the lateral carinae either indistinct or wanting; the median 
carina usually strong or cristiform and cut by one or more sulci, except 
in Arphia; the whole dorsal field of the pronotum generally more or 
less rugose or tuberculate. The tegmina are always well developed
