TEIBE TENEBEIONINI. 



GEN. APHEOTUS, Pering. 

 XENUS (olim). 



APHBOTUS OBOETUS, n. sp. 



Male : Black, glabrous, moderately shining ; apical part of antennae 

 and tarsi piceous-red ; head deeply excavate in the anterior part and 

 with the antennal ridge produced into a long horn strongly curving 

 forward and rounded at apex, the anterior part of the epistomal 

 cavity is also produced into a somewhat broad, lamellate process, 

 bifurcate at the apex, sub-vertical at the base with the furcate part 

 curving slightly backwards, the surface of the head is covered with 

 elongated punctures ; prothorax regularly rounded laterally from 

 apex to base, moderately convex on the median part, and more so on 

 the sides, covered with moderately deep, round, punctures separated 

 by an interval shorter than their diameter, and having a fine, longi- 

 tudinal smooth line in the centre only ; scutellum very short, trans- 

 verse ; elytra oblong-ovate, plainly acuminate at the apex, covered 

 with rows of somewhat closely set punctures as plain in the intervals 

 as in the nearly obliterated striae ; whole under side roughly and 

 deeply punctured. 



Differs considerably from A. tricorniger, Pering., in the shape of 

 the cephalic horns, which are, however, produced in the same 

 manner ; the prothorax is more evenly rounded laterally, and the 

 punctures are smaller. 



Length lOf mm. ; width 4 mm.

I had proposed for A. tricorniger the generic name of Xenus (Ann. 

 S. Afr. Mus., vol. i., 1899, p. 255), but as there is already a genus of 

 birds to which this name has been given, as well as Xenos, a genus 

 of the Strepsicera, I propose to change it into Aphrotus.
