Evidently broader than elytra between humeri (69:62), nearly as broad as elytra in posterior quarter (69:70). Front with a pair of fairly broad and deep longitudinal impressions and a broad keelshaped median elevation that is not very prominent but well developed; median elevation 1.8 times as broad as each of lateral pieces. Puncturation coarse and dense, irregular, partly rugose along internal margins of eyes, with small smooth spot in middle of median longitudinal ridge; diameter of coarsest punctures evidently larger than basal cross of antennal segment 3. Frontal slope before antennal fossae fairly gentle. Antennae long, reaching basal 1/4 of pronotum. Length proportions of antennal segments 2–11 = 8:11.5:10:8:7:7:5:6:6:7.5; segments of club distinctly elongate (6:3.5, 6:4.5, 7.5:4).</paragraph>

Distinctively large, bulging, uneven, a bit longer than broad (55:52), broadest near middle of length, narrowed convexly anteriorly and concavely posteriorly. Median longitudinal groove deep over almost entire length of disk, vanishing just behind slightly elevated anterior margin. Laterobasal depressions shallow though laterobasal prominences developed. Puncturation coarse, in part nonrugosely obliquely confluent, distinctly greater in middle of length; punctures much larger than those of head.</paragraph>

Humeral angles short but prominent, lateral sides slightly convexly and moderately divergent posteriorly (62:70). Humeral and sutural depressions rather feeble, vanished posteriorly.
