Black, shining. Head 
smooth, broad, frontal im- 
pressions well marked, 
clypeal suture distinct, end- 
ing on each side in the fron- 
tal impression ; eyes some- 
what prominent, inclosed 
behind. Pro-thorax broader 
than long, grooved down 
the middle, slightly rounded 
on the sides, gently narrow- 
ing towards the base; pos- 
terior angles rounded off, 
lateral impressions short ; 
marginal border reflexed on 
the sides, reaching as far 
but not extending beyond 
the inner side of the lateral 
impressions on each side of 
the base ; posterior marginal Fig. 2. 
punctures in the lateral 
border at the basal angles. Elytra oval, not convex, a little 
narrower towards the base, rounded on the sides, broadest just 
beyond the middle, sinuate behind, dehiscent at apex, sides and 
apex declivous, striate ; interstices flat, the ninth marked through- 
out its course with umbilicate punctures, those towards the base 
and apex close, but not confluent; lateral margins wide, humeral 
angles not marked. Abdominal segments normal. 
Obs . — The third interstice of each elytron has a series of punc- 
tures, but as the number is not uniform, there being six on the 
right elytron and four on the left, these impressions can scarcely 
be accepted as specific characters.
