Figure 95 

 Omphrale magnicornis Krober, 1913, p. 202. 



The type of this species is much smaller than other material seen 

 by me and is distinguished by its large bulbous third antennal segment. 

 As yet no male has been associated with it. It is close to S. velutinus 

 but separable by the shape of the antenna and bursal plate.

Type-locality: Amerika (Costa Rica) (in Winthems Coll. as 

 pygmaeus Lw.) .
