1890.] COLEOPTERA FROM CENTRAL AFRICA. 483 



Aechon cbntatjrtts, Fabr. 



A well-known African Dynastid, found commonly in the coast- 

 regions of Guinea. 



Family CETONiiniE. 



Ceratorhina savagei, Harris. 



Several examples, differing in nothing, except the rather broader 

 fulvous stripes and spots, from the species as found on Mt. 

 Cameroons. 



ECCOPTOCNEMIS LATIPES, n. sp. 



E. thoreyi simillbna, sed differt c? tibiis posticis hrevihus latis 

 intus ante medium dente magna trianc/ulan instruciis, coxisque 

 posticis (J 5 extus fuhis vel sanguineis. 



Long. 29-33 millim. cS $ • 



Differs from examples of E. thoreyi (Schaum) from the Guinea 

 coast in the silky-golden reflections of its green surface and the 

 stronger sculpture, minutely rugulose-punctate with scattered larger 

 punctures, and the reddish outer-lateral part of the posterior coxae. 

 The apices of the elytra are more strongly sinuated and the sutural 

 tooth longer. In the male the hind tibiae are conspicuously shorter 

 and broader, and the tooth at the commencement of the deep emar- 

 gination at the base is very large. The glabrous inner margin of 

 the same tibiae and the short, scarcely perceptible pubescence of the 

 intermediate tibiae distinguish it, beside colour, from U. harthi 

 (Harold). 



Smaragdesthes mutica, Harold. 



Described originally from examples taken by Pogge in the interior. 

 A species or local form, very closely allied and agreeing in the slight 

 elevation of the anterior margin of the clypeus, but differing in the 

 more elongate form of body, is common on Mt. Cameroons. 



PLiESIOEHINA EECURVA, Fabr. 



A single example of a variety in which the elytra are testaceous 

 yeUow, except a broad border at the shoulders and another at the 

 apex, which remain of the general brassy -green colour. The under- 

 side of the body, legs, lateral margins of the thorax, and mesosternal 

 epimera are reddish. Similar varieties are found on Mt. Cameroons. 



Pl^siorhina cincta, Voet. 



Pachnoda marginella, Fabr. 

 Similar to Cameroons examples. 



Pachnoda inscripta, Gory & Perch. 



One example, differing from Gory and Percheron's figure and 

 description in the upper surface being testaceous-yellow like P. 

 ■pictiwnta (Bohera.), and the abdomen being free from white spots.
