the antennz very slightly compresso-elevated. Pronotum with the 
dorsum finely punctate, frontal margin rounded-truncate, posteriorly 
acuminate, the apical process extended little beyond the knees of the 
hind femora, and little longitudinally concave ; posterior angles of 
the lateral lobes armed on each side with an acutely-produced spine, 
obliquely truncate behind ; the pulvilli of the posterior tarsi dis- 
tinctly flattened below, the first smallest, the second and third equal 
in length, and longer than the first. Length of body entire, female,

Genus MITRITETTIX, Hancock.* 
1. AL. processus, sp. nov. (Plate XXI, fig. 8.) 
Stature little larger than phyllocera, which it nearest resembles. 
Body finely punctate, granulate; grayish ferruginous. Vertex 
rostrate, flattened above, subnarrowed forward, horizontally pro- 
duced, about twice the length of one of the eyes, and at the base 
nearly twice the width of one of the eyes ; viewed from above the 
first half of the process with the sides subparallel, at the middle of 
the rostral margins angularly excavate on each side ; the apical half 
of process being little narrower than the first half, and little dilated 
at about the middle, forward the sides converge forming an obtuse 
angle in front, middle carinate, slightly longitudinally sulcate on 
each side ; head viewed in profile little convex above, the rostrum 
often little bent downward, face oblique ; frontal costa somewhat 
widely sulcate, dividing above the posterior ocelli, the carina above 
passing forward on the underside of the rostrum strongly compresso- 
elevated ; posterior ocelli placed between the submiddle part of the 
eyes, a little in advance of them; median ocellus situated far below 
the eyes ; maxillary palpi with the apical articles dilated ; antennz 
short, inserted scarcely below the antero-ventral border of the eyes; 
maxillary palpi with the apical articles dilated. Pronotum anteriorly 
truncate, little angulate produced at the middle of the front margin, 
posteriorly strongly acuminately produced beyond the knees of the 
hind femora, the process stout ; dorsum deplanate, smoothly punc- 
tate, sometimes slightly rugulose, narrow between the shoulders ; 
prozonal carine parallel, humeral angles widely obtuse ; median 
carina compressed, elevated before the shoulders subtectiform,

Mitraria, the latter name being preoccupied. Vide article in Genera
