fully a third longer than wide, rather narrowly- obtuse behind, the punctures 

 sparse and rather strong ; pubescence coarse ; male with the fifth ventral evenly 

 sinuate at tip, the surface narrowly beveled along the sinus, the first gradually 

 glabrous toward the middle. Length 1.5 mm. ; width 0.8 mm. Pennsylvania. 



punctatus Say 



Much more broadly oval, the body smaller, less polished, black throughout, the pro- 

 notum feebly picescent at the apical angles, not more than three-fifths as wide as 

 the elytra, scarcely more than twice as wide as long, the sides quite strongly con- 

 vergent, very discontinuous and almost straight, the punctures very minute and 

 inconspicuous ; elytra but little longer than wide, obtusely rounded at apex, very 

 finely, rather feebly, evenly but not closely punctured, the pubescence rather 

 short and fine, not very conspicuous ; legs rufo-piceous ; ventral plates approach- 

 ing the hind margin of the segment by a third or fourth of their own length but 

 rather narrow and strongly rounded. Length I.25-I.35 mm.; width 0.8-0.95 

 mm. Nevada (Reno) OCCiduus, sp. nov. 



Evenly and not very broadly oval, black, the frontal margin, mouth, apical angles of 

 the pronotum and legs throughout pale ; marginal bead of the elytra at apex also 

 testaceous ; prothorax nearly as wide as the elytra, finely, not densely and evenly 

 punctate, the sides almost perfectly continuous, strongly convergent and feebly 

 arcuate ; elytra distinctly longer than wide, rather finely but strongly, evenly and 

 not closely punctate, the pubescence moderately long, cinereous and distinct; 

 metacoxal plate approaching extremely close to the suture, broadly rounded ; 

 male with the fifth ventral broadly trapezoidal and sinuato-truncate, the edge nar- 

 rowly beaded and the surface just anteriorly more convex. Length 1.5 mm. ; 

 width 0.95 mm. New. Mexico nanus Lee. 



64 — Upper surface black, each elytron with a large oval red spot on the median line of 

 the disk just before the middle ; form very broadly oval, the head and pronotum 

 black throughout, the latter finely, strongly and closely punctate ; elytra rather 

 coarsely, evenly and moderately closely punctate, not pale at apex, the pubes- 

 cence coarse ; under surface black throughout, the legs fusco- testaceous, the 

 femora black. Length 2.5 mm. ; width I.S5 mm. Texas ; [Tennessee and Loui- 

 siana — Horn.] circumspectus Horn 



Upper surface black, the prothorax bicolored ; elytra without discal pale spot 65 



Upper surface pale flavo-testaceous to piceous-black ; sides of the prothorax discon- 

 tinuous 69 



65 — Elytra distinctly and somewhat broadly margined with red at the apical margin, 

 oval, polished, the head and prothorax generally pale, the latter broadly black 

 toward the middle and base, sometimes black throughout, the sides not quite con- 

 tinuous, rather strongly convergent and evenly, moderately arcuate, the punctures 

 generally distinct but not very dense ; elytra coarsely and sparsely punctate, the 

 pubescence coarse, rather long, ashy and conspicuous ; legs pale to blackish in 

 color. Length 1. 8-2. 7 mm. ; width X.3-I-9 mm. New York, Delaware, Mis-

Elytra not red at tip, or only extremely finely so, the punctures very much smaller and 

 more close-set, the body more narrowly oval ; vestiture rather short and decum-
