DESCRIPTION OF NEW SPECIES 153 



macula usually extending- forward to the humeral forming a lunule; a 

 rather wide entire median fascia with slightly zig-zag edges, sometimes 

 tending to extend basalward along the suture; a similar but usually 

 slightly narrower subapical fascia, and an apical varying in size, some- 

 times involving the apex. Pronotal median macula constricted at middle, 

 frequently with a short reentrant and median line of pale hairs at apex 

 and base ; lateral vittae narrow or broader. Frontal region of the head 

 sometimes darkish. 



Head about as long as wide. Front feebly and broadly concave, 

 scarcely convex in the median line behind the epistoma, surface densely 

 indentato-punctate. Antennae extending a little beyond the pronotal base, 

 not noticeably slender, feebly compressed; second joint oval, almost as 

 wide as long ; third cylindrico-obconical, scarcely longer than the second ; 

 fourth noticeably subangulate anteriorly; fifth wider, distinctly angulate, 

 sides unequal, apical margin oblique ; sixth smaller, as long as . wide, 

 obtusely rounded anteriorly ; seventh oblong-triangular and about as long 

 as wide; eighth similar and slightly thicker; ninth subtriangular and 

 slightly wider than long ; tenth scarcely wider than long, sides arcuate ; 

 eleventh oblong-oval, apex obtusely rounded, about a half longer than 

 wide ; last four joints gradually incrassate. 



Pronotum about a fifth wider than long, evenly convex ; apex arcuato- 

 truncate, apical angles distinctly rounded; base broadly arcuate, angles 

 obtuse, small and more or less reflexed, sometimes scarcely discernible; 

 sides strongly and evenly arcuate in basal half, thence straighter and 

 moderately converging to apex, serrules equal, rather thick and sub- 

 obtuse, almost equally spaced; fimbriae moderately long and not dense; 

 disk densely indentato-punctate. Sometimes the sides are very briefly 

 sinuate before the basal angles. 



Elytra oblong-suboval, twice as long as wide; base truncate, apex 

 rather broadly rounded ; punctures rather coarse, separated by a distance 

 equal to once or twice their own diameter, finer toward apex; surface 

 somewhat transversely impresso-rugose. 



Abdomen densely and finely sculptured. Fifth ventral segment 

 unmodified in the male. 



Legs not stout. Femora subparallel ; surface finely punctato- 

 rugulose. . 



Male. Narrower. Fifth ventral truncate at apex. 



Female. Somewhat broader, slightly wider posteriorly. Antennae 

 similar to those of the male, but rather less stout. Fifth ventral rather 

 broadly rounded at apex. 



Measurements. Length (Types), 2.5-3.2 mm.; width, 1-1.2 mm.
