the African Species of El)£eu>. 235 



Four females before me seem to belong here. They have 

 the biack patches on the elytra larger — the anterior one sub- 

 triangular and nearly reaching the suture, and the curved 

 subapical one angulate in front and extending downward 

 exteriorly behind. E. bonneioii is probably a variety of 

 E. iiwrmiptnnis, the head being black at tiie base in both 

 insects; but till the ^ is found they are best treated as

 patches on each elytron — one basal, triangular (extending 

 inwards to the suture), the other oblique, subangulate ante- 

 riorly, on the disc towards the apex reaching the outer 

 margin, but not the suture) — and the metasteruum black ; 

 the head and prothorax almost smooth, the elytra closely, 

 very finely punctured. Head much narrower than the
