a little broader before the middle, and then gradually (but 
not much) narrowed to the base. Close to the front margin 
there is a well-marked transverse impression scarcely inter- 
rupted in the middle; immediately behind this on the side 
there is a short sinuous impression, which does not reach the 
lateral margin; behind this is a third rather wider impression, 
which reaches the margin, and at the base a short but wide 
impression. Hach of these impressions has a line of large 
punctures; those in the third one less distinct. The central 
portion of the surface is smooth, except for three or four deep 
punctures close to the base. The elytra are ample, nearly 
twice as broad as the thorax, a little broader than the head 
across the eyes, arcuate at the sides; yellow, with the 
shoulders, the outer apical angle, the suture, and a spot across 
the middle of the suture black. On the disk immediately 
below the shoulder are two approximate lines, each consisting of 
three or four large punctures ; these punctures are in a shallow 
impression, and there is another impression occupied by the 
black spot across the suture. Antenne pitchy, with the club 
fuscous.

Long. 2 lin. 
Head very broad, with large punctures irregularly scattered 
over the surface. Antenne testaceous, with the apical two 
joits fuscous. Thorax with deep punctures rather closely 
placed over the surface, leaving the anterior margin smooth ; 
in front of the same width as the head between the eyes, then 
suddenly wider, so as to make a somewhat acute projection, 
from which to the base it is gradually narrowed ; the sides 
between the angular projection and the base rather straight. 
Above there are on each side two oblique smooth ridges, 
which unite near the anterior angle and diverge towards the 
middle of the thorax; and at a little distance from the poste- 
rior angle there is a small round swelling, in the centre of 
which there is asingle large puncture. LElytra short, scarcely 
as broad as the head including the eyes, arcuate at the sides, 
with strong punctures rather closely placed in the sutural 
region (leaving the apex smooth) and at the sides; on the 
disk there are two lines of strong punctures (with a smooth 
ridge between them), the outer line extending to the apex.
