Thorax and median segment closely punctured, the pronotum narrow, 
longer than broad and rounded at the. anterior angles. Median 
segment much shorter than the pronotum, broadened from the base 
and obliquely truncate posteriorly. Abdomen closely and finely punc- 
tured, the basal segment broad, the apical margin a little raised, 
with a shallow transverse groove before it; the second segment with 
three transverse carinae including the raised apical margin, the 
space between the two basal carinae rugose and raised in the middle 
into a broken, irregular, transverse carina. Pygidium very small, 
almost vertical, slightly broadened to the apex, the apical margin 
transverse. Fifth ventral segment punctured rugose. 
Fuscous; a curved band round the eye, broken on the inner 
margin, a short oblique line on each side of the vertex, the posterior 
margin of the head very narrowly, a broad transverse band on the 
first dorsal abdominal segment and a line on the anterior and inter-

&. Mandibles tridentate, the outer tooth much the longest, the 
middle tooth short, the inner tooth bent inwards and fitting into 
the emargination of the clypeus. Antennae nearly as long as the 
head, thorax and median segment combined, slender, the apical 
joints rather feebly arcuate. Clypeus subtriangularly emarginate 
anteriorly, the emargination broader at the apex than deep; punctured 
sparsely and shallowly, with a minute tubercle in the middle Head 
finely and very closely punctured, with a smooth, shallow sulcus 
from the anterior ocellus to between the antennae. Thorax closely 
punctured, sparsely clothed with very short cinereous pubescence f 
the scutellum strongly convex; two longitudinal sulei on each side 
of the mesonotum, the outer one very shallow. Median segment 
- shallowly punctured, rounded, nearly as long as the breadth at the 
base. Abdomen elongate, closely punctured; the basal segment more 
than half as long again as the breadth at the apex, much narrowed
