By the presence of the busal pUcae this species is evidently related to 

 praecox, but the latter has a different color and a broadei thorax. In 

 our own fauna it resembles very closely praedifus, as will be seen in the 

 description of that species. A male loaned me by Mr. Ulke is more 

 slender in form and the elytral intervals more convex. 



This species was unknown to LeConte at the time of his Revision, and 

 first appears as Esthesopus in the List of 1863. 



Occurs from Virginia to Indiana and Texas. 



K. praeditus n. sp. — Piceous, shining, form robust, sparsely clothed with 

 short yellowish pubescence, antennae and legs pale yellow. Antennae slender, ex- 

 tending slightly beyond the hind angles of the thorax. Head convex, a slight 

 vertical depression, punctuation double, the fine punctures nearly obsolete, the 

 coarse punctures large and deep, but not densely placed. Thorax as wide or pos- 

 sibly a little wider than long, sides parallel posteriorly, arcuate at apical third, 

 basal plicae absent, disc convex, shining, with intermixed punctuation, the coarser 

 punctures very much larger at the sides and near the base. Elytra behind the 

 middle a little wider than the thorax, humeri distinct, sides feebly arcuate, surface 

 rather deeply striate, striae coarsely punctured, intervals convex in their entire 

 extent, slightly rugulose and sparsely punctulate. Body beneath paler than above, 

 the lobe of the prosternum ferruginous, the surface with intermixed punctuation, 

 the finer punctures very indistinct, the coarser very well marked. Length .26 

 inch ; 6.5 mm. 



This insect resembles claricollis in appearance, but differs from that 

 and all our other species by the unusually coarse punctures along the 

 sides and base of the thorax. 



From the characters given in the synoptic table by Candeze (vol. iii, 

 p. 275) this species should be related to hepaticus and murinus from the 

 following remarks : " Prothorax plus fortemeut ponctue a la base qu'au 

 milieu du disque. " In the description of hvmilis in comparing the 

 latter with hepaticus he says: " Elle {humilis) en'diff^re par sa couleur, 

 qui est d'un chatain rougeatre clair, et la punctuation du prothorax qui 

 est constituee a la base et sur les parties laterales, par de gros points. " 

 There is evidently some confusion in the table. 



Occurs in Tennessee and Texas. 



E. paa*cus n. sp. — Form moderately robust, piceous or brown, elytra always 

 paler than the thorax, moderately shining, surface sparsely pubescent, antennae 

 and legs yellow. Antennae slender, scarcely reaching the hind angles of the thorax. 

 Head convex, punctuation close, intermixed, the fine punctuation barely evident. 

 Thorax as broad as long, sides nearly parallel posteriorly, arcuate in front, disc 

 convex, without basal plicae, surface moderately closely punctate, punctures inter- 

 mixed and very evenly disposed, the coarser punctures a little more distinct at 

 middle near the apex. Elytra not wider than the thorax, parallel, narrowed at 

 apical third, moderately deeply striate, striae coarsely punctured, intervals convex.
