the S. African Species of Diiiometopus, cfcc. 311 



of the frontal cavity, the cavity itself broad, deep, bimaculate 

 in front, bisinnate behind, the inar^^ins dentate before the 

 eyes ; elytra parallel ; winj^s fnlly developed. 



? . Head and elytra black or brassy black, the latter with 

 at most the extreme apical margin testaceous ; elytra more 

 or less abbreviated, leaving 3 or 4 abdominal segments 

 exposed, much widened or inflated posteriorly ; wings 

 wanting; the vestiturc of the upper surface a little longer.

Males and females have been taken at Estcouit, Frere, 

 and bJalisbury, and there can be little doubt that tluy belong 

 to one and the same species, the almost entirely black 

 elytra of the $ notwithstanding. I have seen the types 

 of D. natalensis, C. ferox, and A. albicauda, the two first- 

 mentioned agreeing perfectly with the descriptions of 

 H. cavifrons. Boh., J. The insect named by Pic C. ferox, 

 var. testaceifroiis, is specifically distinct. The basally con- 

 stricted prothorax and the filiform antennie separate D. cavi- 

 frons from the first section of Hedijbius. 



2. Pinometojjiis feroculus, sp, n. (PI. 1\. fig. 2, head, J.) 



^ . Very like the same sex of D. cavifronx. Boh., and 

 D. testuceifrons, Pic: — Narrower and less shining, the punc- 

 turing excessively fine and close : black, the antennie with 

 the basal four or five joints, the head (except at the base), 

 and the anterior and intermediate tibiie, testaceous ; the 

 elytra each with a rather large rounded patch on the outer 

 part of the disc before the middle, extending narrowly for- 

 wards along the external margin t(i the base, and an apical 

 patch, fiavous ; head with a broad, deep, simple, inter-oenlar 

 excavation, the epistoma flattened and with a transverse 

 lamella in the centre behind it projecting over the anterior 

 portion of the cavity. 



? . Smaller and less convex than D. testaceifrons, ? 

 { = croceoniucu/alus, Pic); the basal joints of the antennie 

 darker (1 black above); the head black ; the yellow markings 

 on the elytra smaller, the apical jjatch sometimes wanting, 

 the elvtra themselves a little more shining than in (^ .
