COLEOPTERA

black, irregularly clothed with a fulvous-flavescent pile. Eyes subcircular, 
but their anterior border is obliquely truncate and subemarginate under the 
sides of the rostrum ; two-thirds of their transverse diameter (on the upper 
side), narrowing the forehead, which is only half of the total width circum¬ 
scribed by them. Rostrum broad, flat, nearly as wide as the head, and 
rather longer, scarcely shorter than wide, subquadrate; sides straight, 
apex sinuately truncate ; a short subtransverse impression near the middle, 
and another at each side of the base, above the eyes; punctate and 
clothed like the head. Antennal groove sub triangular, oblong-acute, per¬ 
pendicular ; its upper border is margined by the side of the rostrum, 
and its posterior is slightly distant from the eye. Antennae rufous, rather 
pilose at the apex. 
Thorax subconic, transverse, its width at the base being nearly double 
its length, and being more than a third narrower at the apex ; convex ; 
base sinuate, with the middle obtusely, and the posterior angles acutely, 
produced, the latter evidently extending beyond the elytra ; posterior 
carina convexly arcuate, distant from the base in the middle, directed 
towards the posterior angles, which it meets, and is there very acutely an- 
gulated, then running upwards along the sides (which are oblique) to one- 
third of the length, where it becomes sinuate and obsolete, terminating far 
from the apex, which is much produced above, and subemarginate in 
the middle; black, clothed with fuscous pile, irrorated with fulvous or yel¬ 
lowish, more condensed beneath anteriorly near the legs. 
Scutellum rather small, semiovate, clothed with a whitish or yellowish 
pile. 
Elytra shortly ovate, twice the length of the thorax, and one-fifth nar¬ 
rower than long ; base of each obtusely rounded, margined; shoulders 
callose, within the basal angles, the base being evidently narrower than 
the thorax ; sides emarginately sinuated behind the base, then dilated to 
two-thirds of their length, roundly narrowed towards the apex, which 
is conjointly emarginate, with the sutural angle slightly obtuse ; inflexed 
margin roundly dilated behind the base, emarginate behind the middle, 
transversely and longitudinally convex ; punctate-striate ; suture and alter¬ 
nate interstices elevated, convex, the innermost is behind the base, as well 
as the flat one interiorly connected to it, more elevated, forming together 
an elongated duplicated tubercle; covered with a fuscous pile ; elevated 
interstices and suture tessellated with fulvous and blackish pile.
