DESCRIPTION OF' NEW SPECIES 159 



a median and subapical fascia, the latter very indefinite ; apical maculae 

 not discernible in the type. Pronotal central macula apparently oval, 

 lateral semilunar vittae not discernible. Hairs on the head more or less 

 diffusely brownish ; those on the prosternum longer and more cinereous, 

 elsewhere beneath similar in length but somewhat darker. 



Head slightly transverse, distinctly wider than the pronotal apex ; 

 eyes moderately large and prominent; front broadly impressed, a small 

 and convex, median and more or less glabrous area just behind the 

 epistomal base; punctures rather coarse, well defined and rounded, 

 intervals more or less indented. Antennae moderately long, slightly 

 stout, scarcely incrassate; second joint oval, about a half longer than 

 wide, rather less than half the width of the first; third joint cylindrical, 

 scarcely longer than the second, slightly widest at apex ; fourth feebly 

 compressed, subtriangular, not prominent anteriorly, about a half longer 

 than wide ; fifth slightly compressed, subtriangular, about a fourth longer 

 than wide, wider than the four following joints, apical angle prominent 

 anteriorly; sixth, seventh, and eighth subtriangular, less compressed, 

 about as long as wide ; ninth similar in form and a little longer ; tenth 

 slightly stouter, more oblong, very slightly longer than wide; eleventh 

 almost oblong-oval, rather less than twice as long as wide, not strongly 

 narrowed at apex. 



Pronotum about a fourth wider than long, rather evenly convex ; apex 

 arcuato-truncate ; apical angles rather broadly rounded into the sides, the 

 latter broadly arcuate, rather more strongly so in basal half, converging 

 moderately to apex, serrules small, rather widely spaced, subacute, 

 fimbriae moderate in length and plumbeo-cinereous in color ; base broadly 

 arcuate and not strongly lobed, sinuate laterally ; basal angles obtuse and 

 distinct; disk moderately coarsely punctate in the central area, intervals 

 about equal to the diameter of the punctures, indentato-punctate apically 

 and basally, laterally very densely indentato-reticulato-punctate. 



Elytra oblong, about twice as long as wide, base rather broadly 

 emarginate, scutellum transversely oblong ; disk rather coarsely punctate, 

 punctures somewhat shallow, separated by a distance equal to one or two 

 times their diameter, a few coalescing transversely producing a somewhat 

 but slight rugoseness, punctures finer toward apex, the latter rather para- 

 bolically rounded. 



Abdomen rather densely punctate ; fifth ventral segment modified in 

 the male. 



Legs rather short and moderate in stoutness. 



Male. Fifth ventral distinctly modified, apex rather deeply sinuate, 

 adjacent surface somewhat impressed, impression limited by denser punc- 

 tuation, hairs slightly coarser, but pale in color, or at least very slightly
