Tctriginae in the Oxford University Museum. 357 
angles nearly straight; posterior angles of the lateral lobes turned 
down obtuse, yet obliquely excised. Elytra small and widened 
posteriorly, apex widely rounded; wings perfectly explicate. 
Anterior femora strongly elongate, superior carinae basally com¬ 
pressed, acute and minutely serrulate ; middle femoral carinae above 
compressed, terminating in an apical denticle ; posterior femoral 
carinae above terminating in a denticle, below longitudinally 
curvate; genicular denticle produced ; posterior tibiae narrow, the 
canthi minutely serrulate and bearing many small feeble denticles ; 
first and third articles of posterior tarsi equal in length, the third 
joint distinctly clavate. 
This genus resembles Bhynchotettix, Hancock,* but 
differs in the cuspidate apex of the produced cephalic 
process, in the absence of a median carina on vertex, in 
the prominent globose eyes, in the presence of elytra and 
wings, in the absence of a spine arming the posterior 
angles of the lateral lobes of pronotum, in the equal 
length of the first and third tarsal articles, and in the 
distinctly clavate form of the third joint of the posterior 
tarsi, 
B. clavipes, sp. nov. 
Body smooth granulate ; eyes prominent and strongly globose ; 
face strongly oblique ; vertex strongly obliquely produced in an 
elongate cephalic process, in profile extended beyond the eyes more 
than the greatest length of one of them, in width equal to nearly 
two-thirds the height of one of the eyes, and terminating in a 
deflexed acute spine; process ventrally compressed, the middle 
forming the facial median carina above, basally sinuate between the 
lower part of the eyes; the process extension viewed from above 
narrower than the vertex backward, longitudinally sulcate, sides 
parallel entire but cuspidate at the apex; vertex between the eyes 
little narrowed forward, broadly transversely fossulate, nearly equal 
in width to one of the eyes, middle not carinate; superior paired 
ocelli placed between the lower third of the eyes; median ocellus 
situated far below the eyes, the distance from the median ocellus 
to the eyes much greater than the distance between the eyes; frontal 
costa narrowly sulcate, forked between the paired ocelli above, 
downwards compressed scarcely elevated; antennae long and 
slender, longer than the head, consisting of fourteen articles, the 
first basal articles crassate, second smaller globose, the next four
