Histrionotus lightfooti (Peringuey, 1892)

Diagnosis: primary costa formed by long spines, similar to those in Somaticus (Clinocranion) spinosus, but approximated to suture and situated at about middle of elytron; the epipleural margination double, with the upper edge formed by long spines, together with its submarginal depression entirely visible in dorsal aspect.

Gen. Trachynotus. Latr.
T. Lightfooti.
Oblongus, niger, pilis decumbentibus sericeis tectus; prothorace transverso, lateribus valde angulatis; elytris oblengo-ovatis, sub-deplanatis, postice acuminiatis, disco margineque laterali spinis acutis seriatis in singulo armatis.
Long. 11-13, lat. 4-6 mm.
Oblong, black, covered with short decumbent silky greyish hairs, and also with a white tomentum leaving two rouud denuded spots on each elytron, the postical one the largest of the two; head punctuated, eyes raised; prothorax transverse with the outer sides acute hardly convex; elytra oblongo-ovate, little convex, once and a half as broad in its greatest width as the prothorax, and acuminated behind; each one has on the disk a row of long, sharp spines slightly directed backwards; these spines are equi-distant from one another; the outer margin has also a row of short spines arranged in the same manner and reaching from the shoulder to the apex. Some examples (female) have sometimes traces of an intermediate series of very short spines between the suture and discoidal row. The underside is briefly pilose, the legs very long and slender, the claws and spurs reddish.

Captured near Port Nolloth, Little Naniaqualand, by Mr. R. 'Light-foot, after whom I propose to name it.
