punctate. Abdomen very finely, sparsely punctate. Legs slender ; tibiae rather 

 densely clothed with short coarse fulvous hairs ; posterior tarsi scarcely three- 

 fourths as long as the tibiae, with the basal joint very much shorter than the 

 remainder. Length 5.0 mm. ; width 1.9 mm. 



Michigan (Marquette). Cab. LeConte. 



The unique type is a female, and the species is quite isolated as 

 far as known, the very coarse punctuation reminding us only of 

 rufipes. 



HI. Mnotata Say. — Long's Expd., II, 1824, p. 285. — Oblong-elongate, 

 parallel, moderately convex ; body throughout, legs and antennae black ; tarsi 

 paler ; each elytron with a large rounded humeral pale reddish spot ; surface 

 polished ; pubescence rather long, semi-erect, dark, not very dense, moderately 

 conspicuous. Head feebly convex, coarsely, somewhat unevenly punctate, the 

 punctures generally separated by their own diameters or more ; eyes moderate, 

 rather convex, separated by twice their width ; antennae a little less than one- 

 third as long as the body, rather robust, feebly attenuate toward apex, the 

 intermediate joints distinctly obconical, about one-half longer than wide, third 

 scarcely longer than the fourth. Prothorax three-fourths wider than long, the 

 apex subtruncate, two-thirds as wide as the base, the latter transverse, the 

 narrow sinuation at each side of the middle feeble ; sides broadly rounded 

 anteriorly, distinctly convergent and nearly straight from behind the middle 

 to the basal angles, which are obtuse but not rounded ; disk broadly, very 

 indefinitely impressed along the middle, rather coarsely, deeply and somewhat 

 sparsely punctate, the basal foveae rounded, feebly impressed. Elytra rather 

 more than four times as long as the prothorax, and, throughout, equal in 

 width to the disk of the latter, parallel, the sides straight, gradually, rather 

 acutely rounded behind, the two bases equal in width ; disk with scarcely 

 impressed series of small moderately close-set punctures, which almost dis- 

 appear completely toward apex, the intervals finely, sparsely and confusedly 

 punctate. Abdomen and metasternum very finely, sparsely punctate, the pro- 

 sternum and propleurae more coarsely and much more densely so. Legs rather 

 short, slender, basal joint of the hind tarsi as long as the remainder. Length 

 6.6-7.5 mm. ; width 2.5-2.6 mm. 



Michigan (Marquette) ; New York. 



The anterior coxal cavities are by no means confluent as stated 

 by LeConte (N. Spec. Col., 1866, p. 138, foot-note), but the thin 

 lamina separating them is almost completely hidden below and 

 between the unusually large and prominent coxse. This lamina 

 gradually becomes broader behind, and widely separates the side- 

 pieces of the prosternum at the posterior margin ; it is on the same 

 level as the latter throughout its length. 



This is a large and conspicuous species, readily known by its
