coarsely punctate. Head (text-fig. 1) a little broader than 

 the prothorax, the frontal excavation broad, very deep, 

 almost smooth and opaque within, trilobate anteriorly — the 

 median lobe erect, the others oblique, angulate, compressed, 

 dentate at the tip, — limited on each side by an angular 

 supra-ocular prominence, and basally by a bisinuate ridge ; 

 antennae very long, rather slender, the outer joints elongate, 

 subfiliform. Prothorax transverse, obliquely narrowed 

 posteriorly. Elytra moderately long, much wider than the 

 protliorax, parallel at the base, rounded at the tip. Legs 

 rather slender; anterior tarsi 5-jointed, simple. 

 Length 3^ mm.

One male. Separable from the males o{ H.maculifer, Ah. 

 {^bimacnlahis, Boh., nee Er.), and II. flavinasus, the only 

 allied S. African forms known to me, by its larger size, the 

 very long antennae, the more extended, anteriorly trilobate 

 frontal excavation, the greater development of the rufo- 

 testaceous portion of the elytral surface, the coarser 

 puncturing of the latter, &c. These insects hear some 

 lesemblance to various species of Dinometopus, which have 

 a basally-constricted longer prothorax, &c.

S . Antennoe moderately long, strongly serrate, black, 

 joints 1-5 partly testaceous (1 nigro-lineate above, 2-5 black 

 along their inner edge) ; head broad (PI. XIII. figs. 11, 11 a), 

 flavous in front, the inter-ocular space and vertex tes- 

 taceous, nigro-maculate before and behind the lateral 

 prominences, the latter also with a black spot within, the 

 inter-ocular cavity very deep, limited on each side by a 

 stout, vertical, horn-like elevation, which is })rodiued into
