172 NEW SPECIES MELYRIDAE, CHRYSOMELIDAE AND TENEBRIONIDAE 



Pronotum transverse, about a fourth wider than long, widest at basal 

 third ; sides broadly arcuate in basal half and less so anteriorly, con- 

 verging moderately to apex, serrules small and subacute, fimbriae 

 moderate in length ; apex broadly arcuato-truncate, angles obtusely and 

 rather broadly rounded; base broadly arcuate in middle six-eighths, 

 sinuate within the angles, the latter subdentate and obtuse; disk moder- 

 ately arcuate from side to side, more strongly so anteriorly, more or less 

 coarsely indentato-punctate, densely so laterally, less so in the central area 

 where the indentations are rather shallow. 



Elytra slightly more than twice as long as wide, at base about equal to 

 the width of the pronotum ; rather coarsely punctate, punctures separated 

 by a distance equal to one-half to three times their diameter, surface finely 

 and rather obsoletely rugulose; punctures much finer toward apex, the 

 latter subserrulate on the edge, sutural angles obtusely but not strongly 

 rounded. 



Abdomen finely, rather densely punctate; fifth ventral segment 

 different in the sexes, being modified on the disk in the male. 



Legs moderate in length and stoutness ; metafemora moderate in 

 stoutness with their dorsal outline distinctly arcuate. 



Male. Parallel and slightly oblong. Antennae with the second joint 

 oval, slightly narrowed at the base, about a third longer than wide, quite 

 equal in length to the third ; the latter cylindrical, twice as long as wide, 

 comparatively narrow ; fourth obconical, feebly prominent anteriorly, 

 about a half wider than long, subequal in length to the third ; fifth rather 

 elongate, subtriangular, about a third longer than the width of the apex, 

 apical margin transverse, as wide as the seventh, distinctly wider than the 

 sixth, fourth, third or second, moderately prominent anteriorly ; sixth and 

 eighth triangular, about as long as wide and subequal ; seventh almost 

 triangular, longer than wide, sides slightly arcuate ; ninth wider, tri- 

 angular, about as long as wide ; tenth subtriangular, less narrowed toward 

 base, sides noticeably arcuate, very slightly longer than wide ; eleventh 

 elongate oval, feebly narrowed apically, almost twice as long as wide. 

 Fifth ventral segment modified ; broadly and rather deeply emarginate, 

 emargination rounded, adjacent surface of the segment rather glabrous 

 and shining, the impressed area semilunar in outline, surface beyond sub- 

 asperate, set with rather long but not dense blackish hairs which extend 

 somewhat on to the apex of the fourth segment ; hairs rather long at the 

 angles of the emargination, the latter rather obtuse. Modified area 

 blackish. 



Female. Subparallel, sides of the body slightly arcuate. Antennae 

 more slender, joints proportioned as in the male; the fourth rather sub- 

 triangular; fifth slightly narrower, less prominent anteriorly, apical
