Syn. : monachus Peringuey, loc. cit., p. 417. 1 (^ (type of monachus), between Zambesi and Limpopo, T. Ayres. Apart from the smaller size, which I cannot consider as important (compare with Henicus prodigiosus and Lihanasidus vittatus), the specimen before me agrees completely in all details with Stal's description of truncatifrons. Peringuey, when he stated that truncati- frons differs from his new species by having but one median spine above on fore tibiae, overlooked the fact that this is true only for truncatifrons Brunner v. W., whilst Stal expressly states for his species that it has 2 spines on the upper inner margin of fore tibiae (excl. apical spines). Brunner's species is, in my opinion, different from that of Stal, for (apart from the num- ber of spines) the frontal cone is, according to the figure by Brunner, much more slender and acute (compare fig. 11 here with that given by Brunner), and the coloration is described by Brunner simply as " picea " without mentioning the striking difference between occiput and dorsum of body, which he could not have overlooked. I propose therefore a new name for Brunner's species and have placed it provisionally in the genus Faku (see Fahu hrunneri). Peringuey seems to consider mimus as more closely allied with truncatifrons than monachus. Although the type locality of mimus would suit truncatifrons better than monachus, I must never- theless identify the latter species with truncatifrons on account of their agreement in coloration. Moreover, the head is considerably broader in the c^ of mimus, and Stal expressly states " caput . . pronoto vix latius," a condition which agrees also with monachus and not with mimus. I have few additions to make to the published descriptions : All genicular lobes unarmed. Middle t
