of the clypeus are subparallel, the anterior margin is 
subtruncate with broadly rounded lateral angles. 
The pronotum is regularly strongly convex, with a 
slight trace of an impressed medial line which disappears 
at some distance from the base; the punctures with which 
the pronotum is covered are very small along the middle 
but stronger and denser set towards the yellow margins 
on which latter they are again wider apart; a small but 
distinct roundish impression is present on the line of 
demarkation between the two colours on the broadest por- 
tion of the pronotum; the sides are narrowly margined, 
slightly concave on the basal half, the basal angles nar- 
rowly rounded and slightly divergent; the base, which is 
as broad as the base of the elytra, is bisinuate, the middle 
lobe broad and regularly rounded. The scutellum has a 
regular triangular shape with convex sides and is provided 
with a few fine punctures. 
The elytra, which at the base are as broad as the base 
of the prothorax, are widest at about one third of their 
length and thence slightly narrowing towards the end in 
regularly curved lines; the disk is rather flat, the sides 
are faintly sloping. Each elytron has sixteen striae (the 
sixteenth marginal) with deep and closely set punctures, 
which striae are for the greater part equidistant; the 2nd 
and 3rd striae run together posteriorly, the 6th and 7th 
are somewhat closer together and likewise united at the 
end; the 10th and 11th are already united about the 
middle of their length, they diverge towards and are dif- 
fuse at the base; the 12th—15th striae originate beyond 
the shoulder which shows a few fine punctures; the 14th 
and 15th striae end at two-thirds of the length of the 
elytron and here the 13th stria approaches the 16th or 
marginal one which begins at the extreme base. 
The pygidium is triangular, much broader than long, 
rather flat, faintly impressed along the middle and covered 
with transverse punctures or striae. 
The mesosternal process is thick at the base and slightly
