148 NEW SPECIES MELYRIDAE, CHRYSOMELIDAE AND TENEBRIONIDAE 



or less constricted at middle, with reentering slender median lines of 

 paler hairs at apex and base ; lateral lunules more or less distinct. 



Head wider than the pronotal apex; frons more or less broadly 

 impressed and usually a small glabrous area is present behind the base of 

 the epistoma, punctures distinct and discrete, intervals somewhat 

 indentato-punctate, surface rugulose at the epistoma. Eyes rather large 

 and moderately strongly prominent. Antennae moderately long and 

 different in the sexes. 



Pronotum about a fourth wider than long, moderately and evenly 

 convex, more strongly so anteriorly and laterally; apex arcuato-truncate 

 and distinctly narrower than the base; apical angles rather broadly 

 rounded ; base broadly and rather strongly arcuate, angles not evident and 

 almost continuously rounded with the broadly arcuate sides, which become 

 less arcuate and moderately convergent to apex, serrations small and 

 rather acute ; disk rather discretely punctured in the central area, intervals 

 flat and as wide or wider than the punctures, almost feebly indentate in 

 part, lateral thirds densely rugoso-indentato-punctate. 



Elytra oblong-oval, punctures rather smaller than on the pronotum, 

 and separated by a distance equal to two times their diameter, somewhat 

 smaller on apical third ; surface more or less feebly transversely impresso- 

 rugose ; apex rather broadly rounded. 



Abdomen quite densely punctato-rugulose ; fifth ventral abdominal 

 segment not modified on the disk. 



Legs moderate in length and stoutness. 



Male. Narrower elongate oval. Smaller males not distinctly 

 parallel. Antennae rather stout, outer three joints incrassate and not 

 compressed; first joint about as long as wide, second a little longer than 

 wide; third obconico-cylindrical, equal to the fourth in length; fourth 

 subtriangular, obtusely angulate anteriorly, wider than the third; fifth 

 a little longer than wide, triangular, distinctly wider than the next three 

 following joints ; sixth subtriangular, equal to the seventh in length ; 

 seventh less subtriangular; eighth less compressed than the preceding 

 joints, a little longer than wide, more obconic than triangular ; ninth, 

 tenth and eleventh joints more robust; ninth as long as wide, sides 

 oblique; tenth as long as wide and subquadrate in outline, circular in 

 transverse section ; eleventh wider than preceding joints, obtusely obovate 

 and about a half longer than wide. Fifth ventral segment rather broadly 

 and feebly sinuate at apex; surface rather asperately sculptured, hairs 

 scarcely darker. 



Female. Somewhat broader. Antennae more slender, relative 

 length and size of the joints similar; second and third rather elongate 

 and equal in length, sixth not noticeably smaller than the seventh.
