* In Ca. stratioticus, Chp., the punctures are so close together that 

 the surface is rendered opaque ; in Ca. sculptilis, Chp., the surface is 

 shining and the larger punctures are distinctly separated, with the 

 interspaces finely punctate. 



t This species, however, has a variety without the fasciae, but with 

 two distinct postmedian spots.
