narrow, cultrate, with about thirty-six small, rounded, blunt teeth. Strigil rather 
large, almost square, with about eight rows of teeth. Intermediate tibie one-fourth 
longer than the tarsi, which are about one-seventh longer than the claws. Pronotum 
with 11-12 yellow lines. Pronotum, clavus, and corium feebly rastrate. Length

9. Moderately elongate, broad, robust, shining ; testaceous, the head with a f\-shaped mark beneath and a 
narrow space before the labrum piceous, these markings connected in one specimen ; the pronotum with 
from 12-16 transverse black lines, the lines becoming broader towards the apex; the elytra nigro-fuscous 
or black, crossed by many undulate flavescent lines, which are but little interrupted on the clavus and 
corium, the markings on the membrane more irregular, the corium usually with a conspicuous pale lunate 
mark at the apex and a space in front of it darker than the rest of the surface, the marginal area with 
the apex, a transverse mark at the middle, and sometimes a space below the base, more or less black ; the 
venter and under surface in great part black ; the anterior tarsi or tibia at the apex externally, the apices 
_ of the intermediate femora, tibiew, and tarsi, and the apex of the hind tarsi broadly, more or less infuscate 
or black. Head with two widely separated, coarsely punctate sulci on the vertex, and some punctures near 
the eyes. Pronotum not carinate, very faintly and interruptedly rastrate. Elytra moderately sinuate 
at the sides below the base; the clavus and corium finely rastrate, the clavus becoming smoother in front. 
Anterior femora very stout; pala long and narrow, much curved on their outer edge, furnished with very 
long hairs within, and with a long curved claw at the apex. Intermediate femora with a fringe of 
very long hairs beneath, the tibie and tarsi subequal in length, the claws shorter than the tarsi. 
g. Head with a shallow longitudinal depression in the middle beneath, and with several deep punctures near 
the lower angle of the eyes; anterior femora strongly, angularly dilated on the iower side towards the 
base ; the pale formed as in the female. Strigil on the right side, small, longer than broad, with four rows 
of teeth, the third row shorter than the others. Ventral segments asymmetric on the left side. 
Length 93-10 millim.
