2. Lispinus impressicollis iridescens , new subspecies.

Pitchy, the antennae, palpi and legs clear ferruginous. Head narrower than the prothorax, with two impressions on the vertex, distinctly punctate, moderately shining. Antennae short, thickened toward the apex, the penultimate segments strongly transverse. Prothorax as wide as elytra, moderately transverse, greatly widened toward the middle; posteriorly, considerably contracted, yet scarcely sinuately, the median groove short, very narrow, finely and sparsely punctured, scarcely shagreened, moderately shining. Elytra little longer than prothorax, as long as wide, distinctly bluish iridescent, very finely and sparsely punctured, moderately shining, scarcely shagreened. Abdomen moderately shining, sparsely punctured. Length 2 mm.

This race, perhaps likewise a distinct species, stands near subspecies robusticollis Bernhauer. It differs essentially in its somewhat smaller, narrower form, finer and sparser puncturation, finer impressions on the prothorax, and especially in the more distinct iridescence of the elytra.
