144 NEW SPECIES MELYRIDAE, CHRYSOMELIDAE AND TENEBRIONIDAE 



size. Pronotal central macula evidently hourglass-shaped or oval, it may 

 have a narrow median reentrant pale line from apical and basal margins ; 

 lateral semilunar lines rather obscure; hairs darkish on front of head. 

 Pronotal fimbriae moderately short and pale in color. 



Head somewhat transverse, front nearly plane, feebly and longi- 

 tudinally bi-impressed anteriorly, impressions separated by a feeble con- 

 vexity, which is more or less glabrous at the epistomal base, punctures 

 moderate, well defined, feebly impressed, separated by a distance equal 

 to one or two times their diameter, intervals flat, feebly indentated toward 

 the periphery; muzzle short. Antennae somewhat slender and rather 

 long, very feebly incrassate and slightly compressed, less noticeably so in 

 the outer joints, somewhat dissimilar in the sexes ; first joint very stout ; 

 second oval, about a fourth longer than wide, narrowing slightly toward 

 base; third subcylindrical, about twice as long as wide, as long as the 

 fourth ; fourth moderately compressed, almost subtriangular, feebly sub- 

 angulate anteriorly ; fifth elongate ; sixth and seventh equal in length, less 

 than a half longer than wide, scarcely subtriangular ; eighth a little longer 

 than wide, shorter than the ninth, slightly oblong-triangular; ninth and 

 tenth distinctly longer than wide, somewhat oblong-triangular; eleventh 

 elongate oval, slightly narrowed at apex, twice as long as wide ; outer joints 

 not noticeably wider. 



Pronotum about a fourth wider than long, rather evenly convex, but 

 more declivous antero-laterally ; apex arcuato-truncate ; apical angles 

 broadly rounded into the sides ; base broadly and rather strongly arcuate, 

 somewhat lobed, more or less sinuate laterally; basal angles obtuse and 

 more or less evident but not strong; sides broadly and moderately 

 strongly arcuate, straighter and moderately convergent anteriorly, 

 serrules short, blunt to subacute, intervals equal to their base ; disk rather 

 discretely punctured in middle third, punctures distinct, separated by a 

 distance equal to one or two times their diameter, intervals more or less 

 glabrous centrally, more or less indentated apically and basally, laterally 

 very densely indentato-reticulato-punctate, surface rather dull. 



Elytra oblong, about twice as long as wide, sides parallel, very feebly 

 arcuate, apex broadly rounded, punctures rather coarse, separated by a 

 distance equal to half to three times their own diameter, surface more or 

 less irregular from feeble transverse impressions, punctures finer and 

 more widely spaced toward apex. 



Abdomen very finely and evenly punctured, more densely so on the 

 fifth segment which is unmodified in the male. 



Legs moderate in length and stoutness ; femora rather stout, meta- 

 femora somewhat rapidly narrowed at the trochanters ; tarsi rather long 

 and slender.
