elevated, edge emarginate behind the anterior angle, and 
conspicuously angulate well before the posterior angle, surface 
deeply punctate, punctures anteriorly round, posteriorly oval 
or somewhat elongate, 6-costate, two outer coste shortest and 
parallel to the thoracic edge, the others are much elevated 
and equidistant, the two median coste are a little the longest 
and turn from each other at the base; the elytra 6-costate, 
with the outer margin and the two sutural edges also elevated, 
1-3 coste are twice broken by two transverse depressions, 
the third costa being very remarkable as the median portion 
viewed sideways looks like a conspicuous nodule, the fifth 
costa is the strongest, the sixth weakest, both the last com- 
plete, the interstices are very clearly carinulate, with a single 
row of equidistant punctures. ‘The elytra are in part reddish. 
The propygidium has three tubercles transversely placed in 
the middle, the centre one somewhat linear; the pygidium 
closely punctate, with an elevation thus 4 in the middle; 
the prosternum has large, deep, and closely-set punctures, 
striate at the coxe; the mesosternum bisinuous anteriorly, 
and with the metasternum has very large punctures or fovez 
set somewhat in transverse lines, and on the median area of 
the metasternum are two triangulate smooth spaces; the first 
segment of the abdomen has a line of seven fovex along the 
anterior edge ; legs and antennz piceous.

costata ; elytris 3 carinis elevatis, interstitiis obscure punctato-

L. 2 mill. 
Oval, rather convex, little shining; the forehead is wholly 
punctate, little uneven, slightly elevated behind the insertion 
of the antennz, not carinate or costate; the thorax, nar- 
rowly marginate, obtusely angulate before the base, 6-costate, 
outer costa shortest, with a wide interstice between it and 
the second, the second is shorter than the third but parallel 
to it, the two centre coste reach the margin behind the neck, 
and gradually turn inwards anteriorly, but do not meet, the 
surface is punctured like that in 0. tuberculatus; the elytra 
are 3-costate, with an intervening carina corresponding to 
the second, fourth, and sixth strize; below the shoulder is a 
transverse depression which crosses the first costa to the 
second carina (or fourth stria), the interstices are obscurely 
carinulate with intervening punctures; the propygidium
