Clypeus sparsely, distinctly punctured ; the apex with an incision 
which becomes gradually narrowed from the apex to the base, i.e. almost

on the lower part ; sides of scutellum with a broad raised longitudinal 
keel on the sides ; the sides of the post-scutellum with a blunt tubercle ;

is a smooth line which becomes gradually widened towards the apex ; the 
apex of the post scutellum is bluntly rounded ; the first and second 
segments are finely, closely punctured ; the base of the second more

Clypeus a little longer than wide, the apex broad, transverse, strongly 
punctured ; the puncturation on the head and thorax is strong and close ; 
the pubescence dense and white ; post-scutellum roundly, broadly 
depressed above, the sides projecting into teeth ; the first abdominal 
segment is cup-shaped, longer than it is wide at the apex, shortly pedun- 
culated ; the second is longer than wide, depressed in the centre of apical 
third ; there is a distinctly defined crenulated furrow near the apex, which 
is smooth and strongly reflexei ; the basal two segments are closely, strongly 
punctured ; almost the apical half of the third and fourth are finely 
punctured ; the second ventral segment is more strongly punctured, 
except for a large smooth space, furrowed down the centre on the basal 
half ; the tegulae are larger than usual and are strongly, closely punctured.
