ON THE CETONIID^ OF SOUTH AFRICA.

and that of the present Cape species. The whole insect is black, except the nine last joints 

 of the antennae, which are fulvous. M. Gory only states that the three joints of the clava 

 are fulvous in the Senegal species; but, perhaps, this is a mere omission, and therefore I 

 shall register our Cape insect as follows. 



Sp. 9. (Macrominus) Oplostomus fuligineus, Oliv. 



Cremastocfieilm fuligineus, G. P. p. 110. tab. 15. fig. 1. 



38. We have to pass on now to the following sub-genus. 



Sub-genus 2. Anoplocheilus, M'L. 

 Antenna of ten joints, the first obconic, and the second globose. 



Mandibles having their corneous external process very httle longer than the membranaceous 

 part. 



Maxilla homy, prismatic, and long, having the terminal process not distinct from the inner. 



Mentum narrow convex, with the anterior edge semicircular. 



Head small, subquadrate. Body convex and thick. Epimeron very visible between 

 thorax and elytra. Scutellum large, triangular. Mesosternum blunt, and not produced. 

 Feet short and strong, with the fore tibise tridentate, and the posterior femora some- 

 times incrassated, as are also the posterior tibiae, which are always externally sub- 

 bidentate. 



This sub-genus has a prismatic maxilla, something like that of Genuchus ; only terminating 

 in three equal horny teeth. Genuchus has only two teeth to its maxillae. But both sub- 

 genera agree with Oplostomus in the outer side of the terminal process of their maxillae, having 

 no brush of hair. 



Sp. 10.:^(Macrominus) Anoplocheilus spinitarsis, n. s. 



Descr. Anoplocheilus nigronitidus punctatus, clypeo minuto emarginato lateribtis rotundatis, 

 sutura prominente, vertice pills flavis hirsute, tliorace sub-semicirculari postice sinuato, 

 ^ elytris striato-punctatis, corpore subtus pills hirsuto, femorlbus posticls valde incrassatis, 



articulo prlmo tarsi medii et postici extiis in spinam longam triangularem producto, pseiido- 

 nychiis distinctls. 



Long. 5^ lines. 



39. I do not know whether I am altogether accurate in placing the following Cape insects 

 with indistinct pseudonychia in this sub-genus, because I have not dissected them ; but they 

 appear to agree in several respects, and possibly only differ as belonging to another section of 

 the sub-genus. In external appearance they are all three very much alike. 



Sp. 11. (Macrominus) Anoplocheilus setosus, n. s. 



Descr. Anoplocheilus fuliginosus caplte quadrato clypeo antice reflexo, elytris supra foveolis semi- 

 circularibus setigeris impressis, corpore subtus pills aureis rarls vestito. 



Long. 5^ lines. 



Note. This species like the following, differs from Anoplocheilus spinitarsis, in having no spines on the 

 first joint of the posterior tarsi. 



Sp. 12. (Macrominus) Anoplocheilus tomentosus. 



Cetonia tomentosa, G. P. p. 226. tab. 51. fig. 5? 

 Note. The description and figure of Gory and Percheron answer so well to my insect, that I am un- 

 willing to believe it to be a distinct species, although they say that the Cetonia tomentosa of King is a 

 Mexican insect. By the way, with their usual accuracy, these gentlemen have another " Cetonia tomen- 

 tosa" from Mexico, which is probably a true Cetonia. I shall merely now repeat that as the clypeus of
