Moderately long-oval, piceous-black, polished, sometimes tinged with 

 rufous on the base of prouotum, front of head, and on tlie costal area. 

 Head longer than wide, remotely ciliated with fine bristles, broadly 

 dei)ressed around the front of clypeus, the margins strongly recurved ; 

 surface of the lateral lobes uneven, minutely and obsoletely rugulose, the 

 usual broad wrinkles obliterated ; pits present each side near the mid- 

 dle, one in the exterior angle near the eye, and another on the inner 

 margin of the eye near its middle; the pits setigerous ; tylus as long 

 as the lateral lobes, a little narrower at the apex, the lobes curving 

 against its tip but not meeting in front of it; the depressed lines bound- 

 ing it become almost obliterated where it rises behind the middle, and 

 then become expanded and deepened at its base ; ocelli large, placed on 

 a line with the base of the eyes ; base of head moderately convex, 

 smooth. Antennre ferruginous, the second joint a little shorter than 

 the third. Eostrum ferruginous, or pale castaneous, reaching to the 

 intermediate coxse; the basal joint a little shorter than the bucculoe and 

 almost inclosed by them ; the bucculse dull, minutely rugulose; second 

 joint long, moderately compressed, a little arched ; the third feebly com- 

 pressed, a littl^ widened, about of the same length as the second ; the 

 apical joint shortest, not very slender. Pronotum a little wider than 

 long, the sides oblique, decidedly narrowing toward the front, sparingly 

 ciliated, the surface moderately convex, the transverse line deeply in- 

 dented, sharply separating the anterior lobe, remotely punctate, and the 

 punctures scarcely' forming a disconnected series from those which ex- 

 tend back upon the posterior lobe, and across its width to the submar- 

 gin ; on the sides the punctures are massed, extending from before the 

 humeri to the anterior angles, and invading an arcuated impression, 

 which runs forward from the pit at the end of the transverse line ; disk 

 of the anterior lobe impunctate, but with a shallow, longitudinal, 

 impressed line in front; the marginal stria very distinct, and with a 

 few obsolete pits in its bounding line; humeri distinct, impunctate, the 

 sinus adjoining small, shallow. Scutellum convexly prominent near 

 the base, the immediate base with the impressed line minutely punc- 

 tate ; surfiice coarsely, remotely punctate, somewhat in transverse, 

 irregular lines almost to the tip ; tip posteriorly with a few fine punct- 

 ures ; the lateral marginal line deep, long, with faint vestiges of pits
