cinereous pubescence. Head small, two-fifths as wide as the 

 prothorax, the antenn;^^ rather long and slender, gradually and 

 very feebly incrassate, the penultimate joint longer than wide. 

 Prothorax somewhat longer than usual, scarcely one-half wider 

 than long, rapidly subconical throughout, the sides arcuate, not 

 becoming parallel at the base, the basal angles rather strongly 

 prominent posteriorly but distinctl}- rounded. Elytra slightly 

 wider than long, equal in length to the prothorax ; distinctly 

 narrowed from the base, the imln'ications rather large but feeble, 

 and subtransversely and finely reticulate. Abdomen very evenly 

 tapering throughout, the erect black set;^ long and conspicuous 

 to the base. Length 1.5 ram.; width 1.05 mm. 



New York to Iowa and Texas. A small and widely distributed 

 species, varying but little in the large series before me. The 

 male has a large and broadly rounded emargination occupying the 

 entire apex of the sixth ventral segment, the fifth being com- 

 pletely unmodified at the apical margin. The epipleurffi are 

 narrow and do not quite attain the rounded apical angles; they 

 became vertical toward base externally and are practicall}- glab- 

 rous throughout. 



In assigning setifer to opica Say, as a synonym. Dr. Horn 

 entirely neglected to observe the long bristling setfe throughout 

 the length of the abdomen, which would have shown him its true 

 position at once, irrespective of the radically difi'erent form of 

 the epipleurffi.

Oblong-oval, convex, rather shining, black, the basal margin of 

 the pronotum very narrowly and the apices of the abdominal 

 segments paler ; base of the elytra broadly and indefinitelj^ rufes- 

 cent, less broadly so toward the scutellum ; under surface rufo- 

 piceous, the legs red-brown ; pubescence not very dense and un- 

 usually long, dark fulvo-cinereous in color and conspicuous. 

 Head somewhat small, much less than one-half as wide as the 

 prothorax, the antennte graduall3' incrassate. Prothorax rather 

 short and wide, fully three-fifths Avider than long, the sides 

 strongl}- arcuate, very convergent anteriorlv but becoming paral- 

 lel a long distance from the base; basal angles gradually and 

 only feebh' prominent posteriorly and broadly' rounded. Elytra
