genera Aenidea or Platyxantha might have equally served well for its reception, 

 since none of these genera are well defined, but as there is already one species of 

 Stenop/atys described from Africa with which the present one agrees pretty nearly, 

 it might as well be included in that genus. I only know the male of this species, 

 the female is in all probability devoid of the excavation of the head which is also 

 fonnd in several species of Aenidea from the East. 



Spilocephalns (?) metallicus sp. nov. 



Elongate, metallic diuk bine, the antennae and tibiae black, head and thorax 

 impunctate, the latter deeply snlcate, elytra sparingly and very finely punctured. 



<J. Antennae longer than the body, pubescent, the posterior tibiae armed with 

 a slender spur projecting beyond the apex. 



? . Antennae shorter than the body, posterior tibiae unarmed. 



Length 2i lines. 



(J. Head broad, impunctate, the eyes very large and prominent, occupying the 

 entire sides of the head, frontal ele various well raised, clypeus triangular, acutely 

 raised, antennae longer than the body, black, pubescent, the fourth joint longer 

 than the third, all the joints, with the exception of the second, very elongate and 

 slender ; thorax scarcely one half broader than long, the sides straight, the surface 

 impunctate, with a deep transverse sulcation, metallic blue ; elytra broader at the 

 base than the thorax, rather obsoletely and very finely punctured, their epipleurae 

 prolonged to the apex ; posterior tibiae with a projecting spur placed at the inner 

 or lower margin ; anterior coxal cavities closed or very slightly open. 



Hal/. Sierra Leone (Mus. Eothschild, and coll. Jacoby). 



It is with considerable doubt that I have placed this species in my genu^ 

 Spilocepkalus since the antennae in that genus are robust and comparatively short, 

 the same organs in the present species resembling rather those of the genus Ozomena 

 {Theopea). The cavides of the anterior coxae are closed in tha female specimens I 

 have exammed (agreeing with Spilocepkalus) but slightly open in male specimens. 

 Mr. Gahan has likewise described a suj)posed species of Spilocepkalus (S. distanti) 

 in which the male is similarly provided with a tibial spur, and it is on that account 

 principally that I have placed the species in the present genus.
