Pubescence long, pale, semierect. Habitus: Fig. 38h.

Head not very transverse; eyes moderately large; carina of post-ocular border salient, forming a prominent tooth on temples at a distance from posterior margin of eye; punctures coarse, umbilicate, dense, irregular on entire disc, leaving the anterior part of frons impunctate. Lateral margins of pronotum strongly bordered in anterior 2/3 rds, the surface immediately below border glossy and impunctate; puncturation of disc roughly arranged in four median parallel series, on either side with irregularly scattered punctures between these and a continuous series of punctures along lateral margin in anterior 1/3 rd, an arcuate series of a dozen punctures enclosing bases of the median series, and six smaller punctures between this and base. Fully winged; elytra ample, strongly elongate, with pronounced humeral angles; puncturation dense, fairly homogeneous, a little sparser on sides than near suture. Abdominal puncturation dense, about as coarse as that of elytra, punctures disposed randomly.
