.specimen the pubescenca is more dcns3 at the third interspace, and on the 

 secjud t.) the fifth interspaces for a slijrt dis:auce beliind the middle. 



7. O. rugicollis, n. sp. 



Oblong oval, brownis'.i-black, above \vi!h scattered elongate yellow 

 scales, which on the elytra form an indefinite pattern of a transverse band 

 at the base, and another just behind the middle connec ed by some less 

 densely placed scales. Head convex, n 'arly smooth, beak as long as the 

 pro hora.v:, attenuated towards the tip, strongly curved, punctured, fr,)ntal 

 oonstrictijn d ep. Prothorax wider than long, feebly narrowed from the 

 base for two thirds tin length, rounded on the sides, slightly constric ed 

 near the tip; very deeply and oarsely rugose, leaving narrow eleva'ed 

 folds, much as in RhyssematuH; there are a few scattered yellow hair like 

 scales; base scarcely sinuate. Elytra a little wider at base than the protho- 

 rax, gradually nai'rowed be'.iind, scarcely separately, but almost conjointly 

 rounded at tip; s'.rite deep, interspaces flat, each with a row of small dis- 

 tant punctures. Prosternum very broad between the coxae, coarsely punc- 

 tured, mark:'d in front with two lines converging behind, and enclosing a 

 smooth triangular space. Club of antenni3e small, oval rounded, pubescent; 

 claws divergent. Length 4.2 mm.; .17 inch. 



]\Iiddle and Southern States. The pygidium is less exposed than usual, 

 but is perpendicular, so that this species cannot be confounded with Cen- 

 trinus, in which it is nearly horizontal, or at most oblique. 



PSEUDOBARIS n. g. 



The species of this genus have the second joint of the funicle no longer 

 than the third, and the club not larger, oval, with the first joint pubescent 

 and sensi ive, and constituting less than one-half the mass; the claws are 

 approximate and slightly connate at base. In these respects they agree 

 with I'richoharis, but differ by the front coxae being very widely sepa- 

 rated, and by the absence of dense scaly or hairy vestiture, though there 

 are a few scattered scales on the elytra of each species. The prosternum is 

 broadly sulcate in front; the limits of the groove are less sharply defined as 

 in Aulobaris.
