 very pale as usual in this section; head rather well developed, some- 

 what more than three-fourths as wide as the prothorax, the ocular 

 puncture moderate and not at the edge of the eye; antennae brown, 

 paler basally, not as long as the elytra, the medial joints about three 

 times as long as wide; prothorax a fourth wider than long, evenly 

 rounded at the sides, which are oblique and sinuate posteriori}', the 

 angles right, the anterior angles blunt; surface as usual, but with 

 the large deep foveae nearer the carina than the middle, the carina

 elytra oval, fully one-half longer than wide, one-half wider than the 

 prothorax, the strise fine, moderately impressed and minutely sub-

 the eye; antennae piceous, rufous basally, about as long as the elytra, 

 rather thick, the medial joints between two and three times as long 

 as wide; prothorax relatively larger than in the two preceding and 

 distinctly transverse, two-fifths wider than long, the sides broadly

 are right and sharp; base barely visibly wider than the apex; foveae 

 large, rugose, not so abrupt or deep as in the preceding, .the carina 

 moderate; elytra one-half longer than wide, barely two-fifths wider 

 than the prothorax, the sides evenly arcuate as usual in this sub- 

 section, the striae fine, entire, feebly impressed internally, obsoles- 

 cent externally, not definitely micro-punctulate, the foveae near two-
