with faint, median, shining line; elytra and elytral declivity shining, elytral striz not 
impressed, punctures fine, in distinct rows, interspaces smooth and irregularly punc- 
tured, declivity steep, subconvex, strize slightly impressed, interspace 3 with a few 
minute granules, apex obtusely rounded, with slightly elevated subacute margin 
which also forms the lateral margins of the declivity. Rosslyn, Va., in Lindera sp.,

rounded from vertex to apex, which is narrowed and retuse, posterior lateral margin 
of declivity not elevated; body clothed with long erect hairs, longer on sides; elytral

several obscure longitudinal lines and impressions; elytra with sides parallel, shining, 
strize and interspaces equally punctured in approximate rows, strie with row of very 
fine hairs, interspaces with longer erect ones in approximate rows, declivity convex, 
faintly, broadly retuse, interspace 1 faintly elevated, stria 1 impressed, interspace 3 
with two small teeth on face of declivity and 4 with one or two teeth, 1 and:3 with
