The vertex is strongly and closely punctured, the punc- 
tures all clearly defined; the sculpture on the front and cly- 
peus is hid by the dense hair. Base of mandibles punctur- 
ed; the apical tooth is long and sharp-pointed ; the two sub- 
apical are of almost equal size. Mesonotum and scutellum 
closely punctured. The area on the metanotum is bare, opaque 
and is bordered by broad curved, shallow furrows. The basal 
segments of the abdomen are obscurely punctured ; the penul- 
timate segment is strongly and closely punctured and is covered 
with longish black hair ; the last segment is much more closely 
and uniformly, but not so strongly, punctured; its base has an 
almost vertical slope ; the apex projects and has a wide shallow 
incision in the centre above which isa spot of golden pubes- 
cence. ‘The hair on the legs is long and pale, on the base of 
the hinder tarsi below, golden.

scutellum, closely and uniformly punctured; the median seg- 
ment is not so strongly or closely punctured ; the basal area 
is strongly aciculated and finely striated. Abdominal segments, 
including the transverse depressions, closely punctured; the
