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

 the protLorax, the frontal excavation broad, very deep, 

 almost smooth and opaque "svithin, 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 bisiuuate ridge ; 

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

 suhfiliform. Prothorax transverse, obliquely narrowed 

 posteriorly. Elytra moderately long, much wider than the 

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

 rather slender; anterior tarsi S-joiiitcd, simple.

 coll. Fry) . 



One male. Separable from tlie males of H. maculifer. Ah. 

 { = bimaculatus, Boh., nee Er.), and U. flavinasus, tlie only 

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

 very long antennye, 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 bear some 

 lesemblance to various species of Dinometopus, which have 

 a basally-constricted longer prothorax, &c.
