frontal costa strongly advanced beyond the eyes, the rami somewhat 
widely sulcate, divided above the posterior ocelli near the vertex, 
and slightly divergent forward. Pronotum anteriorly produced 
scarcely beyond the head, the front margin on each side straight, 
convergent forward, angulate, but with obtuse apex; dorsum strongly 
compresso-cristate ; the median carina forward between the shoulders 
strongly sinuate, posteriorly acuminate, extended little beyond the 
hind femoral apices. Elytra rather wide, oval, bearing a large black 
macula transversely intersected by a light fascia near the apices ; 
wings fully explicate and extended beyond the pronotal apex. 
Posterior femora somewhat incrassate ; the first and third articles of 
the posterior tarsi subequal in length, the three pulvilli of the first 
tarsal articles nearly equal in length. Length of body entire, male, 
14 mm.; pronotum 12°5 mm.; posterior femora 7 mm.

Genus TETTIGIDEA, Scudder. 
1. TZ. planus, sp. nov. 
This species has no spine at the termination of the superior carina 
of the middle femora, and the elytra are plainly coloured without 
macula ; it resembles Scudder’s species Tettigidea cuspidata. 
Body granulate; ferruginous, often fusco-variegated. Vertex 
distinctly wider than one of the eyes, somewhat depressed and 
smooth, narrowed forward, the supraocular lobes small, the front 
margin advanced about as far as the eyes, the median carina absent, 
the frontal carinule on each side very little compressed, little 
rounded-concave ; frontal costa narrowly sulcate, little compresso- 
elevated between the antenne; maxillary palpi yellow, widely 
compresso-dilated at the apices, the apical articles oval. Pronotum 
anteriorly acute spiniform produced nearly as far as the front of 
vertex, the spine nearly straight, the front margin on each side of the 
spine strongly concave ; posteriorly cuneate, extended backward 
nearly to the apices of the hind femoral knees ; dorsum granulate, 
between the shoulders somewhat tectiform; median carina little 
incrassate, subundulate, nearly horizontal, little compressed and 
pereurrent. Elytra elongate, acuminate toward the bases and apices, 
the external faces plain coloured and granulate; wings abbreviated. 
Hind femora elongate; the tibiee fuscous with pale annulation near the 
bases, the first and third articles of the posterior tarsi subequal, the 
first, second and third pulvilli respectively gradually increasing in
