This little species is closely allied to 0. osculatii, Guer., 

 which, however, is nniformly coloured. It has almost the 

 colouring of 0. bidentatus, Drap., and, as in that, the femora 

 are bright yellow. In 0. ranunculus the pygidium is also 

 bright yellow and the upper surface is opaque and setose. 

 The male is also distinguished by the quite smooth unpunc- 

 tured head, without trace of carina3.
