Form average, parallel ; dull black, lower surface and 
appendages brown, antennse paler basally ; pubescence very 
inconspicuous. Head dull, granular. Prothorax subquad- 
rate, moderately narrowed in front, scarcely so behind, 1/5 
or 1/6 wider than long; sides broadly and more or less 
evenly arcuate, margins faintly crenate; disk convex, with 
entire sinuate carinae nearly paralleling sides, these carinae 
well defined inwardly, not defined (continuous with disk) 
externally; median longitudinal groove obsolete anteriorly, 
faint at middle, defined by a pair of faint carinae at base; 
surface of disk dull but not distinctly granular, finely and 
not very closely punctate. Elytra % or 1/5 wider than pro- 
thorax; sides nearly parallel basally, broadly rounded near 
apex; apices not produced; each elytron with 2 moderate 
costae externally, evanescent on declivity; 4th interval

than 2nd or 4th ; 4 discal striae fine but distinct, indistinctly 
punctate ; surface of disk dull but without distinct granules 
except on 4th interval and less distinctly on costae (rarely 
a few on base of 3rd interval). Lower surface with scat- 
tered granules less obvious than usual; prosternal process 
about i/2 width of mesosternum between middle coxae ; pros- 
ternum carinate before front coxae; abdomen nearly uni-
