a crown of short spines on the tip of the tibia, and the first 
two tarsal segments. 
Genitalia . — Ultimate ventral segment of female nearly as long 
as width at base, elevated in the middle; posterior margin trun- 
cate, with a broad median notch; py gofers narrow, moderately 
exceeded by the oviduct; the margins and tip studded with 
short, stout, orange spines; length, 4.50 mm.; width on center 
of costa, nearly 2 mm. 
LarvcB. — Half -grown specimens taken the middle of Septem- 
ber already possessed the characteristic head and pronotum of 
the adult. The antennae were longer than the body, basal joints 
very large, and arising from under a well marked ledge; color, 
bright green, with six black spots, as follows: A pair of round 
ones occupying the anterior half of the eyes, a pair on base, 
and another on posterior margin of the wing pads, directly 
behind and in line with the eyes, anterior pair partly concealed 
by the pronotum. Spines on the genitalia, and legs stronger 
than in the adult. 
This species was taken in upland pastures in which Andro- 
pogon scoparias^ Bouteloa Mrsuta and curtipendula predominated. 
Adults were taken the latter half of August; half- grown larvm 
were found September 13th and 17th. 
This is a very peculiar species, and suggests a relationship 
between Euacantlms and XestocepJialus, two of the lower genera, 
placed respectively in the sub-families Jassinoe and Tettigonince. 
XESTOCEPHAEUS PULICARIUS VAN D. 
Bull. Buffalo Soc. Nat., Sci. vol. IV, 1894. 
This is a narrow, convexly conical headed little species with 
broad maculate elytra and a brown vertex marked much as in 
Tettigonia Meroglypliica. Length about 3 mm. 
This species might easily be mistaken for a Deltoceplialus but 
for the ocelli which are situated nearly half way from the eyes 
to tip of vertex. It was found rather commonly on blue grass 
in shaded locations through July and August. 
Very generally distributed north, and specimens have been 
received from Mississippi (Weed). 
XESTOCEPHALUS CORONATUS N, SP. 
(PL xix, Fig. 3.) 
Form and size of pulicarius nearly, but with head and pro- 
notum shining black, with white markings; length, female, 3 
mm.; male, hardly 2.50 mm.
