terminal joint, subfusiform, the first joint of the flagel¬ 
lum globose, rather robust, the second short, subclavate 
and subequal with the rest, which increase gradually in 
length and substance to the terminal one, which is the 
longest, and laterally compressed ; face flattish ; clypeus 
subquadrate, very convex and very pubescent; “ labrum

the margin of the posterior one, at the apex, slightly

The male differs in having “ the sixth segment of the 
abdomen emarginate, and with a strong tooth on each
