much more prominent than the anterior, which are small and 

 obtusely blunt though evident, the basal angles right, distinct; 

 scutellum evenly and broadly ogival; elytra three-fifths longer than 

 wide, somewhat dehiscent apically, barely a third wider than the 

 prothorax, the sides rapidly converging and feebly arcuate from 

 base to the somewhat narrowly obtuse apex; punctures rather fine 

 and sparse but distinct, the surface smoother and more shining 

 than in palparis, the raised lines very feeble; sterna much less 

 pubescent, the tarsi short, moderately stout. Length (cf ) 22.5 mm.; 

 width 9.0 mm. Kansas simplex n. sp. 



Both of these species are rather rare and known as yet only by 

 the male. LeConte left palparis, which has come to be erro- 

 neously recorded as "palpalis" in our lists with Priomis, though 

 noting the radically different sculpture of the antennae; he however 

 failed to note the different form of the tarsi, which, with the struc- 

 ture of the maxillary palpi, renders a separate genus necessary.

This genus was proposed by LeConte to receive his Prionus 

 integer, as well as the Prionus emarginatus of Say; it is the only one 

 of our Prionini in which the pubescent pronotum appears, so far as 

 known, but probably there are also glabrous forms, judging from 

 the negative evidence of failure to mention any dorsal vestiture 

 in the descriptions of integer and Prionus innocuus. The species 

 may be distinguished among themselves as follows: 



Prothorax with a tooth at the sides, the angles all obtuse, the tooth 

 generally well before the middle 2 



Prothorax without trace of median tooth, the sides smoothly rounded 

 at or before the middle 3 



2 Pronotum without distinct pubescence; color piceous; prothorax 

 finely punctulate, narrowed anteriorly, the sides unidentate at the 

 middle, the posterior angles subobtuse; elytra sparsely, rugosely 

 punctate; antennae (cf ) 13-jointed, stout, strongly imbricate, the 

 last joint complex, as though formed by two connate joints, the 

 inferior lobes of the joints slightly sinuate. Length 24.0 mm.

 Acad. Phila., ser. 2, II, p. 107] Integra Lee. 



Pronotum pubescent; color castaneous, shining; head, pronotum and 

 sterna clothed with long flavo-ferruginous hair, densely punctate; 

 antennae 14-jointed, glabrous, perfoliate, imbricate, the inferior 

 lobes emarginate; mandibles black at tip; prothorax but slightly 

 margined at the sides, where there is a single tooth at or before the 

 middle, the angles obtusely rounded; elytra somewhat uneven, 

 punctured; female glabrous, with simple antennae. Length (cf, 9)
