Original Description

Content:  Transcribed by Laurence Livermore P. opacus.- Dark brown, without lustre, punctured, pubescent ; head with the space between the antenniferous tubercle filled up, antennæ pubescent, brown, with the apical two-thirds of the tip joint yellow, upper surface of the head covered with yellowish pubescence ; thorax roughly punctured, a transverse, slightly elevated lobe near each anterior angle, posterior margin with a fine, transverse, impressed line, anterior angles acute, posterior ones rounded lateral margins sinuated, edge slightly recurved, posterior margin truncate ; scutellum and corium of the hemelytra punctured and uniform with the thorax; membrane pale brown, nervules very irregular, tip reaching the end of the fifth segment; tergum and beneath uniformly roughly punctured, pubescent, incisures of the tergum yellowish at the lateral margins; legs dark brown, pubescent, tarsi honey-yellow. Length 10 millim. Humeral breadth 2 ½ millim. male female. Takanosima, Japan. This genus presents an entire anomaly amongst the Coreoid Hemiptera with simple legs; it seems to have most affinity with the Gonoceridæ, but it differs from them in the length of the hemelytra and the irregularity of its nervules; its position in the series, as the system now stands, is very difficult to define. Uhler, 1860: 226
