the pattern of red and black. H. vagans is smaller than H. armatus Sharp, and 

 rather more short and compact, with shorter legs, which are not spiny Hke those 

 of the American species. The lateral margins of the pronotum are strongly 

 serrate and fringed with spines, as in H. armatus, but not narrowed behind, 

 and the elytra are shorter, more parallel-sided, rather less convex, and bear 

 large, closely set pmictm-es in longitudinal rows. The pattern of the elytra is 

 similar to that of the typical species, but an anterior band is not traceable and 

 the antemedian black spots are not united. Probably, however, the pattern 

 is variable. The sides of the metasternum are strongly punctured and the 

 4th sternite is very short.

 This appears most to resemble a South African species, 0. capensis, Grouv., 

 but it differs in having the terminal joint of the antenna shorter, the prothorax
