somewhat wide apart; below. the eyes are similar ridges, but behind the eyes and 
between them and the base of the mandibles the ridges are broken up by eross bars. 
The pro-mesonotum has similar sculpture to the head, but the ridges are less regu- 
lar, more vermicular, broken here and there by cross bars. Both nodes have a few 
broken ridges on their upper surfaces, and a few longitudinal ones on their pos- 
terior surfaces. In addition, the entire body, including the scapes and legs, is 
covered with an extremely delicate fundamentual reticulation, which is most dis- 
tinct on the head and gaster (which latter has no other sculpture), and faintest 
inside the scrobes and beneath the projecting plates of the thorax, and on the 
epinotum. 
There are a few long stiff hairs on the front of the clypeus, and the whole body, 
including the legs and antenne, is furnished with short, stiff, erect hairs, which 
on the antenne, legs, and under surface of the gaster are pale testaceous, and on 
the rest of the body, brown. Pubescence nil.

ee with a bronze sheen. Some specimens have a faint iridescence on the 
ead. 
Mandibles triangular, terminated by a long curved tooth, which is preceded by 
five or six large and small ones. Clypeus convex in centre, the anterior border 
widely and shallowly emarginate. Frontal area triangular, fairly distinct, not 
impressed. Frontal carine short and parallel. 
Head sub-triangular, longer than broad, widest just behind the eyes, sides 
convex, occipital border feebly concave, almost straight. Hyes flat, placed in centre 
of sides. The scapes extend just beyond the occiput. 
Pronotum nearly as broad as long; mesonotum narrow, about twice as long as 
broad, sloping downward to the base, where the stigmata are prominent; there is 
a, deep narrow impression between the mesonotum and epinotum, and the base of 
the latter rises high above, rounded in profile, the declivity, which is concave at 
the base, descending sharply ; seen from above, the base is longer than wide, and 
narrower at apex; scale high, but lower than epinotum, somewhat thick, feebly 
convex in front, straight behind; seen from above, is more than twice as broad as 
long. Gaster a rounded oval, not overhanging the scale. 
The whole insect somewhat shining; mandibles punctured, head, thorax and 
gaster microscopically reticulate.

A grey pubescence is fairly abundant on the sides of head, thorax 
and gaster ; mandibles with abundant hairs, a few long ones on occi-
