apically, the external surface very lightly punctate; wings fully 
explicate. Legs light ferruginous, margins of anterior and middle 
femora little compressed, entire. Length of the body entire, female, 
11 mm. ; pronotum 10°2 mm.

Genus RHYNCHOTETTIX, nov. 
Body smoothly punctate ; face profoundly retreating; vertex 
strongly rostrate, viewed from above the rostrum very much longer 
than the length of one of the narrow eyes, the apex distinctly 
rounded, the middle longitudinally carinate; frontal costa very 
narrowly sulcate, the carina above compressed, percurrent forward 
underneath the process to the apex; eyes viewed from above nar- 
rowly subelliptical, in profile compresso-conoidal ; superior ocelli 
placed on a plane with the lower third of the eyes; the mediay 
ocellus placed far below the eyes; antenne inserted little before 
(below) the antero-ventral border of the eyes. Pronotum truncate 
anteriorly, the margin little convex produced, posteriorly acuminate, 
but not spinose, toward the apex little concave and extended back- 
ward little beyond the posterior femoral knees; dorsum narrow 
between the shoulders, cylindrical forward, the prozonal carine 
here obliterated ; median carina low deplanate forward, but little 
elevated and distinct posteriorly ; lateral carina low; lateral lobes 
with the anterior margin below obliquely excised, the posterior 
angles of the lateral lobes little laminate outwards, distinctly pro- 
duced in an acute spine on each side. Elytra and wings wanting. 
Middle femora elongate, margins little compressed entire ; genicular 
and antegenicular denticles moderately stout; the posterior tibie 
little ampliate toward the apices, the canthi spinose, the first article 
of the posterior tarsi distinctly longer than the third. Type Rhyn- 
chotettia rostratus.* 
1. £. rostratus, sp. nov. (Plate XXI, fig. 7.) 
Fusco-ferrugineous, with lighter longitudinal striation on each 
side of dorsum, posterior femora with the external faces below stri- 
ated with fuscous. Rostrum triquetrous, strongly produced and 
when viewed from above about one and a half times longer than the 
length of one of the narrow eyes, the base of process subequal in 
width to one of the eyes; frontal costa viewed in profile roundly 
excavate opposite the eyes, and below very slightly sinuate, between
