148 CASEY 



blunt ; base transversely truncate, the angles very feebly prolonged 

 backward and blunt ; surface coarsely, deeply and closely punc- 

 tate, more densely so sublaterally and again more finely and sparsely 

 near the sides, where it becomes rather broadly subexplanate pos- 

 teriorly, though narrowly so anteriorly, the bead not very thick, 

 strongly elevated ; elytra about a fourth longer than wide, the 

 sides subparallel and very feebly arcuate, rounding a little at base, 

 strongly rounding posteriorly to the broadly ogival tip, the surface 

 nearly smooth, the punctures rather small and feeble, varying but 

 little in size, becoming faintly muricate laterally and smaller 

 apically, much smaller and less deep than those of the pronotum ; 

 prosternum strongly, rather closely punctate, the process well 

 developed, not margined at apex ; hind femora coarsely and con- 

 spicuously, though very remotely, punctate, the abdomen finely, 

 sparsely so medially, more coarsely and closely, muricately so 

 laterally. Length 8.8-1 1.2 mm.; width 4.6-5.9 mm. 



punctulata Horn 



Elytra densely dull, unevenly and closely punctured, the pubescence 

 coarser and more conspicuous, ihovigh almost equally thinly dis- 

 tributed, the moderately long erect fulvous setse along the sides of 

 the body more developed 3 



3 — Body broadly oblong-oval 4 



Body narrowly oblong, with the sides more parallel 5 



4 — Form very broad, moderately convex, dark castaneous, the under 



surface, legs and antennae paler, dark rufo-ferruginous ; head less 

 coarsely, very deeply and unequally punctate, very densely so cen- 

 trally, much less densely before the suture, nearly as in pitncttc- 

 lata in outline but less broadly rounded and less prominent at 

 the sides before the eyes ; antennae similar ; prothorax similar 

 throughout, except that it is a little shorter and much more than 

 twice as wide as long, with the apical sinus rather less deep, the 

 almost equally coarse and perforate punctures still denser ; elytra 

 similar but with the parallel sides very slightly more arcuate, the 

 punctures about as large as those of the pronotum but not so 

 deep and intermixed with smaller punctures, very close-set and 

 muricate throughout ; under surface nearly similar, except that 

 the coarse and very conspicuous punctures of the hind femora 

 are generally less sparse, the basal joint of the anterior tarsi very 

 slightly less stout and somewhat less obliquely sinuato-truncate at 

 tip. Length 8.2-10.7 ^nm. ; width 4.4-5.7 mm. 



muricata Horn 



Form rather less broad and more evenly elliptic, more convex, blackish- 

 brown in color, the legs piceous-black, the abdomen still blacker, 

 the sterna and antenna paler, rufo-ferruginous ; head as in muri- 

 cata and similarly punctate but more broadly and less obliquely 

 rounded at the sides, the antennae similar; prothorax less trans- 

 verse, barely twice as wide as its median length, the sides much 

 less converging from the base and more narrowly and more feebly
