1907.] Catalogue of the Coleoptera of South Africa, 295 



The number of species recorded from the South African area is 

 223 divided into 101 genera. This is a good example of how great 

 the tendency is, nowadays, to divide the genera on the slightest 

 plausible reasons ; for there are few Sub-Families among the Coleop- 

 tera which are as closely related to each other as the Cetonin^: are. 

 The multiplication of species on the flimsiest characters excels that 

 of the genera. I have satisfied myself, by an examination of the 

 male genital organs, that a great many of them cannot be considered 

 as valid. 



The endemic genera number 33, distributed as follows : — 



Tkichiini, 4. Agcnius ; Stegopterus ; Brachagcenius ; Eriopel- 



tastes. 

 Myodermini, 2. Elpidus, Xiphoscelidus. 



Cetononi (Cetonides) 15. Xiphoscelis; Bhinocceta ; Lipoclita ; 

 Atrichelaphinis ; Goraqua ; Trichostctha ; Odontorrhina ; 

 Ischnostoma ; Gariep ; Heteroclita ; Baceloma ; Mazoe ; 

 Gnathocerida ; Amazula ; Atrichia. 



(Cremastochilides) 12. Macromima ; Phymatopteryx ; 

 Anatochilus; Plagiochilus ; Proxenus ; Astoxenus ; Genu- 

 chus; Trichoplus; Myrmecochila; Anatochilus; Scaptobius; 

 Placodidus. 



Six of these genera will probably be met with outside the South 

 African area. 



Tribe TKICHIINI 



In the insects included in this Tribe, the elytra are either convex 

 or plane, the ligular part of the mentum is deeply and broadly 

 scooped out, the labial palpi are inserted in the outer face of the 

 mentum, the upper lobe of maxillae is elongated, simple, and bears a 

 long pencil of hairs, and the inner lobe is not distinct, the clypeus is 

 a little longer than the head, the antennal club is as long or much 

 longer than the pedicel in the £ ; the basal angles of the prothorax 

 are not rounded but are always angular, and even sharply so, and 

 the median part is not arcuate ; the scutellum is cordiform and as 

 broad as long ; the apical end of the hind tibiae does not end in three 

 teeth or spines, and the spurs are long, the upper one is occasionally 

 strongly compressed in the 5 (Stegopterus) ; the tarsi, especially the 

 hind ones, are very long and slender, with the claws long ; the basal 

 joint is longer than the second, and there is no mesosternal process, 

 except in Stripsipher. The body is partly pubescent, or glabrous, 

 the pubescence is not squamose.
