COLEOPTERA. 171 



latter color except a broad irregular transverse band at the posterior thinl 

 and tlu-ee small sijots near the base, one on the suture beliind the scutellum, 

 and one on each elytron nearer the suture than the exterior edges and at 

 one-third the length from the base, all of black ; the posterior band does not 

 attain the extreme margins with its full color but is very narrowly paler 

 along the lateral edge, it is deeply emarginate anteriorly on the suture and 

 is very strongly and narrowly produced along tlie suture posteriorly, becom- 

 ing finely attenuated and reaching the extreme tip, but with a slight paling 

 of the color ; epipleurae very pale ; under surface black except a small poste- 

 rior portion of the prosternum and the apical portions of the last venti-al 

 segment which are paler ; legs very pale tiavate throughout ; antennae pale 

 and very uniformly rufo-flavate throughout, palpi same ; pubescence short, 

 rather sjiarse and coarse, pale flavate in color ; integuments polished. Head 

 scarcely one-half wider tiian long; front feebly and evenly convex through- 

 out, very strongly coarsely and deeply punctate ; punctures round, distant 

 by scarcely more than their own widths, perforate, interspaces flat ; apical 

 margin very broadly rounded, sides feebly sinuate near the eyes ; labrum 

 coarsely and deeply punctate ; antennae as long as the head and pronotum 

 together, basal joint nearly three times as long as wide, sub-cylindrical, as 

 long as the third and fourth together, second slightly elongated, two-thirds 

 as long as the third which is narrowed toward base, third much shorter than 

 the fourth and very slightly shorter than the fifth, fifth to tenth sub-equal, 

 slightly compressed, sub-triangular, much longer than wide, symmetrical 

 internally and externally, eleventh more than twice as long as wide, having 

 a broadly oval terminal process. Prothorax having the sides almost parallel 

 from the basal angles to one-fourth the length from the apex, very feebly 

 arcuate and almost imperceptibly sinuate along the basal portions ; apex 

 transverse, fully five-sixths as long as the extreme width across the tips of 

 the basal processes ; the latter much longer than wide at base, very acute, 

 narrowly and strongly carinate ; basal margin bro^idly arcuate at the bottom 

 of the emargination ; disk medially distinctly longer than wide, very coarsely 

 and evenly punctate ; punctures rounded, very deep, perforate, distant by 

 slightly more than their widths, interspaces flat. Scutellum longer than 

 wide, convex, black, strongly arcuate behind, feebly so anteriorly, sides 

 nearly straight, finely punctate. Elytra as wide as the pronotum; sides 

 parallel in the basal three-fifths and feebly arcuate, thence elliptically 

 rounding behind; immediate apex acutely rounded ; disk scarcely one-half 

 longer than the head and prothorax together and slightly more than twice as 

 long as wide, moderately convex, feebly declivous at base, strongly striate ; 

 striae strongly and coarsely punctate, intervals flat, finely and asperately 

 punctulate, striae abruptly terminating along an imaginary transverse line 

 tangent to the posterior margin of the scutellum, leaving a large space at the 

 base of each elytron without striae or punctures ; humeral angles entirely 

 obsolete ; sides broadly rounding, each elytron being rather acutely rounded 

 at base and very feebly depressed toward the scutellum. Entire under sur- 

 face very strongly and coarsely punctate; posterior coxae pieeousblack, 

 longest at two-fifths their width from the middle. Tarsi finely and densely 

 ciliate beneath, fourth joints rudimentarily lobed beneath. Length 4.7 nun. ; 

 width 1.4 mm.
