Abdomen of P. Thomsoni c? from above; in this species sixth and seventh segments are not visible on the dorsal side; the last segment is the eighth with its apical im- pression. prothoracic parts form at the humeri a curious, somewhat elevated knob; the thoracic disc has generally very sparse and fine, some- times scarcely perceptible hairs, present only as dorsocentral rows and behind the humeri, but in some species the disc is relatively densely clothed all over with more obvious hairs and in this case scutellum bears similar hairs. Thorax has no bristles; the marginal hairs on scutellum are often a little longer than the other hairs, in furcatus (non-Danish) somewhat bristly; on propleura there is in many species a fan of distinct hairs. Abdomen elongated, cylindrical.
